The Team You'd Join
Unlimited Industries, a seed-stage frontier-tech startup founded in 2025 and backed by Andreessen Horowitz, is hiring across software, electrical, civil, process, and supply-chain functions in a deliberate mix, and only candidates who match its specific technical and cultural bar advance through its process. The company closed a $12 million seed round from Andreessen Horowitz and CIV in December 2025, Axios Pro reported, with CEO Alex Modon confirming the raise. The mission: reverse a half-century decline in the ability to deliver critical infrastructure by compressing engineering timelines from months to days through an AI-native design platform. Every hire so far works in person, five days a week, in San Francisco, with a Construction Lead role also open in Texas.
Unlimited thinks the fix isn't just better software — it's a specific blend of engineers who know how those facilities actually get built, paired with operators who can move steel and transformers from factory to site.
The engineering side spans multiple disciplines tied to live postings on the Zero G Talent board, BuiltIn, and the a16z job board. A Senior Electrical Engineer owns power-system studies, grounding, protection coordination, and the translation of expert judgment into an automated electrical design product covering utility-scale power, battery storage, solar, gas generation, substations, grid interconnections, and data centers. A Senior Civil Engineer handles structural and civil design for the same project classes. A Senior Process Engineer drives end-to-end process design for large-scale capital projects — heat and material balances, PFDs, P&IDs, emissions control, equipment sizing — across gas power, industrial, chemical, or polymer plants, with simulation tools and AI coding agents listed as advantages. A Modeling and Analysis Engineer builds and maintains the modeling, performance, and optimization tooling that feeds the automated design engine, requiring systems thinking, first-principles reasoning, and deep expertise in one or two areas. A Software Engineer (All Levels) partners with hardware and analysis engineers to develop product architecture, databases, cloud infrastructure, and customer-facing capabilities, with emphasis on AI coding agents and physical-world engineering software.
Two supporting functions round out the slate. A Supply Chain Lead builds the company's first supply chain operation for large-scale energy and data center projects: manufacturer relationships for transformers, switchgear, inverters, steel, and cable; capacity expansion; lightweight processes; AI-automated repetitive work; and travel to suppliers, factories, and job sites. A Business Development lead owns commercial development from prospecting through signed projects, identifying developers and hyperscalers, leveraging investor and industry networks, educating customers on iterative engineering, and translating customer needs into product priorities, all in an early, in-person San Francisco environment.
Across every role the postings signal the same filters: first-principles reasoning, cross-disciplinary technical breadth, hands-on execution, and the ability to prioritize high-impact problems. The company also lists a general-application path for candidates passionate about the mission who don't fit a defined role, a deliberate signal that cultural alignment and mission orientation matter as much as any single skill set.
What the Offer Looks Like
Unlimited Industries has not published salary bands for any open role. The current positions on Zero G Talent, BuiltIn, and a16z carry no public compensation figures. Any specific number encountered is speculative until the company confirms it in conversation.
At a startup this young, compensation gets negotiated individually rather than slotted into published grades. Equity will be a meaningful component of every offer, and the cash portion reflects both the founder's fundraising stage and the premium required to hire senior talent into an early-stage environment. The board shows a mix of senior-level and all-levels titles; Unlimited is hiring for senior roles but also lists "All Levels" for software and modeling positions. Senior frontier-tech engineers in San Francisco command market rates starting well above $200,000 base even before equity.
Broader market data offers guardrails. The U.S. Bureau of Labor Statistics reported that paid leave benefits alone cost employers an average of $2.94 per hour as of September 2022, roughly 7.4 percent of total compensation. Indeed found mentions of PTO in job postings more than doubled between January 2020 and May 2024. Empower reported roughly one in five workers would reject an offer lacking unlimited PTO, while 26 percent would accept lower pay in exchange for it. FAU research found PTO access reduces turnover by 35 percent overall, and flexible scheduling matches retirement plans in retention impact. BambooHR found approval rates hadn't kept pace with leave requests in 2024; nearly half of U.S. employees expected to finish the year with unused vacation days.
| Company | Healthcare Benchmark |
|---|---|
| NuStar Energy | 100% of employee premiums (≈37% of salary) |
| Gradient AI | 100% in-network preventive + 12 weeks paid parental leave |
| GoDaddy | 100% premiums from day one |
| Spectrum | Absorbed all medical, dental, vision cost increases for 12 consecutive years |
Replacement costs for specialized talent can reach a full year's salary. Voluntary turnover costs U.S. businesses more than $1 trillion annually. For a team this size, losing one engineer is an existential risk. That dynamic gives candidates leverage, but it also means the company has likely structured offers to maximize retention: meaningful equity vesting, accelerated schedules for key milestones, and benefits that reduce departure likelihood. Unlimited's PTO policy is not publicly disclosed; candidates should ask directly about it. If the company offers unlimited PTO and genuine schedule flexibility (both common in early-stage frontier tech), those benefits carry real economic value that should factor into any offer comparison.
For the Construction Lead role split between San Francisco and Texas, geographic differentials may apply. Clarify whether the offer is indexed to location or role.
No public data exists for Unlimited's specific bands. That's not unusual at this stage. It means the first offer you see is a negotiation, not a policy. Come prepared with market comparables for your discipline, a clear view of your equity-to-cash preference, and questions that test whether the benefits match the retention research. Ask directly about base, equity percentage and vesting, refresh cadence, healthcare coverage for dependents, PTO policy and actual utilization rates, and whether the company has a minimum-time-off expectation.
Inside the Interview Room
Public information on Unlimited's interview process is sparse. The company publishes no detailed playbook, and third-party aggregators show only fragments. Two sources offer clues: a Glassdoor entry for "Unlimited Innovations" (a name close enough to warrant attention but not confirmed as the same entity) and a set of practice questions on interviewchamp.ai that reference Unlimited Industries directly.
That outline (screen, then panel) is standard for early-stage hardware-adjacent startups, but the company-name mismatch means it should be treated as directional, not definitive.
The interviewchamp.ai questions reveal what the software-engineering track actually tests. The prompts are behavioral and architectural, not algorithmic:
- "Describe a full-stack application you built from scratch: what were the most critical architectural decisions you made?"
- "How have you approached integrating AI or machine learning models into production systems, and what challenges did you encounter?"
- "Tell us about a time you identified a critical bottleneck in a complex system and how you prioritized solving it."
- "What experience do you have building software for engineering, manufacturing, or physical-world products?"
- "How do you balance shipping quickly with maintaining technical excellence, especially in a high-pressure startup environment?"
- "Describe your approach to extreme ownership: give an example of when you took full responsibility for a project outcome."
- "Why does our mission to revolutionize construction through automation resonate with you?"
Together, the questions signal a process that weighs systems thinking, production-grade ML experience, and comfort with hardware-software integration over LeetCode-style puzzles. The "extreme ownership" and "mission resonance" prompts suggest the team screens for autonomy and alignment, traits that matter when every hire represents a double-digit percentage of headcount.
No public source confirms the number of rounds, typical timeline, or whether a take-home project or onsite technical exercise is standard. The board listings imply the company is hiring across electrical, civil, process, supply-chain, construction, and business-development functions simultaneously; each discipline likely runs a tailored loop with the relevant lead. The process is iterative and conversation-driven; the founding team evaluates directly. Prepare concrete narratives around shipping physical-world systems, owning outcomes end-to-end, and making architectural trade-offs under resource constraints.
San Francisco Brain, Texas Muscle
Unlimited Industries operates from a San Francisco headquarters that houses its core engineering, design, and business teams, while construction operations fan out across active project sites in Texas and other U.S. regions. Five of the six current openings on Zero G Talent pin to San Francisco. The Construction Lead role reads "San Francisco or Texas", a signal that field leadership splits time between the office and the build sites where AI-generated designs meet dirt and steel.
That split reflects the origin story. Founder Alex Modon cut his teeth on a major industrial project in Texas, "one of the most construction-friendly regions" in the country, where he experienced the delays and fragmented tools that later drove him to start Unlimited. A GlobeNewswire announcement notes the company is "currently delivering projects in the United States" across mining, energy, advanced manufacturing, and data centers, with international expansion on the roadmap. The same release highlights a near-term focus on "rapidly building power in the US for data centers, critical minerals, and advanced manufacturing projects," sectors that cluster in Texas, the Southwest, and the Mountain West.
San Francisco serves as the platform's brain. The proprietary system that "generates and evaluates hundreds of thousands of design configurations in parallel" runs there, staffed by the electrical, civil, and process engineers the company is hiring. The Business Development and Supply Chain leads also sit in the Bay Area, close to the capital and partner networks that fund and supply large-scale infrastructure. But the platform's output — "optimized designs that simply are not achievable through manual effort" — only creates value when it reaches a job site. That handoff is where the Construction Lead earns their keep, translating continuous design iteration into poured concrete, erected steel, and commissioned equipment.
Unlimited's model compresses pre-construction engineering from six months to just a few weeks, per the December 2025 funding announcement. On one recent industrial project, the platform explored tens of thousands of configurations and identified a design that "reduced projected capital costs by over 50 percent." Those numbers only materialize when the field team can execute the optimized plan without the traditional change-order friction. The Texas presence isn't incidental; it's where the company proves its platform survives contact with reality: permitting, weather, subcontractor coordination, and the thousand small deviations that derail conventional projects.
The company's website frames the contrast bluntly: "Outcome-based milestones vs Time & material / massive contingency costs; Unified modern technology platform vs Fragmented legacy tools." That philosophy demands a physical footprint that mirrors the software architecture, a tight core in San Francisco that pushes design authority to the edge, where Construction Leads and field crews operate with real-time access to the same living model. As Unlimited adds project sites across mining, energy, and data-center corridors, the ratio of office to field personnel will shift. The current team is heavily weighted toward the platform; the next hiring wave will likely tilt toward the build side.
For candidates, the location question is binary: San Francisco if you write the code that designs the plant; Texas (or the next project state) if you turn those designs into operating infrastructure. The Construction Lead posting makes the duality explicit. Everyone else on the board today sits at headquarters, but the company's trajectory suggests that won't hold. Each completed project "makes the system smarter, strengthening the models, cost data, and workflows," and each new site becomes a potential permanent outpost. The map is still being drawn.
Who Lasts
The team reads like a deliberate collision of two worlds that rarely share a cap table. On one side: Tara Viswanathan and Jordan Stern, who built Rupa Health from zero to an $80 million revenue run rate and a nine-figure exit — Viswanathan as CEO raising $40 million in venture capital, Stern leading every design and AI product decision through hundreds of thousands of users. On the other: James Betts, a chartered mechanical engineer with 15 years delivering billion-dollar infrastructure across oil & gas, hydrogen, mining, and transmission at BP, PwC, and Anglo American's First Mode division, where he ran the EPC team. Alex Modon sits between them, a multidisciplinary engineer who spent two years partnering with national labs, founders, and the U.S. Department of Energy to commercialize hard tech, then built the company he couldn't find when trying to accelerate R&D to commercial scale.
That composition is the hiring signal. Unlimited does not hire generalists who "wear many hats." It hires specialists who have already proven they can operate at the extremes of their domain — whether scaling a venture-backed SaaS platform to a nine-figure outcome or delivering a transmission project on a mine site — and who now want to apply that depth inside a vertically integrated, AI-native construction company. Every open role demands a seniority level that implies independent ownership of a critical workstream from day one.
What unites the team is a tolerance for — and a track record of — collapsing feedback loops that traditionally take months. The company delivers milestone-based outcomes, not billable hours. There are no design freezes, no change orders, no version control by filename. Engineers work embedded with customer teams, and every project feeds data back into models that make the next one faster. Candidates who need process stability, who optimize for predictable sprint cadences, or who expect a clear separation between "engineering" and "the business" will not last. The ones who advance have already operated in environments where the specification changes daily, the hardware ships before the software is perfect, and the only metric that matters is whether the physical asset gets built on time and on budget.
Geography filters the pool further. The roles are based in San Francisco (Construction Lead also lists Texas), but the work happens at project sites: power plants, data centers, critical mineral facilities, advanced manufacturing campuses. The company is already active in the United States, with international expansion planned. That means travel. It means showing up at a job site in Texas and making decisions that affect a project's critical path while the concrete is still curing. Betts has done this for 15 years. The Construction Lead they're hiring will need to do it too.
There is no culture-fit abstraction here. The culture is the work: vertically integrated, incentive-aligned, outcome-obsessed, and moving at a pace the traditional EPC industry considers impossible. The people who thrive are the ones who have already proved they can build in that mode (whether they learned it scaling a health-tech company to a nine-figure exit or delivering a billion-dollar hydrogen project at BP). The resume doesn't need to check both boxes. It needs to check one of them deeply, and show evidence the candidate is ready to learn the other side fast.
The next project site isn't on the map yet. But the person who runs it is already reading this board.
