ProvenMetal's $200K Founding Engineer Must Shrink Seven Days to Code
The Signal in the Garage
A garage in San Francisco's Dogpatch district ships circuit boards in five to seven days while the rest of the industry measures in weeks. That speed is the visible edge of a supply chain being rebuilt from scratch, and ProvenMetal is actively recruiting for one critical role in its American-based PCB assembly operations, with a rigorous screening process designed to filter candidates for precise technical competencies and practical experience.
ProvenMetal arrived in Y Combinator's Summer 2026 batch with a company only weeks old and a thesis the accelerator had already rejected once. Johnny Doyle and Will Carkner, both Engineering with Management students at Trinity College Dublin, first applied with Syncra, an IoT building-management venture. Y Combinator told them the team was strong but the idea lacked ambition. They flew to San Francisco, booked thirty-plus conversations with manufacturers and hardware companies in a week, returned with five letters of intent, and walked into a second interview with a new company and a new problem: domestic PCB assembly. The accelerator accepted them. A third Trinity student, Alex McConnell, joined shortly after to make a four-person team.
The timing is not accidental. Two decades ago the United States produced roughly 30 percent of the world's printed circuit boards. Today that share sits near 4 percent, Trinity College Dublin's data shows. The gap matters because drones, robotics, defense systems, and energy infrastructure all need boards assembled domestically, and the capacity to do it quickly at scale was hollowed out along with the factories. Hundreds of billions of dollars are now being spent to rebuild the industry in America, Trinity College Dublin reported. ProvenMetal positions itself inside that flow: one team sources every component, manages fabrication through qualified partners, assembles and tests in San Francisco, and ships a full quality record with each order. Their standard turn is five to seven days from quote to ship, with no expedite fees. Fully domestic builds are available when ITAR or other compliance requirements demand it.
The company's own site lists capabilities that read like a spec sheet for hard hardware: up to 32-layer HDI stackups with blind, buried, and stacked vias; SMT assembly down to 01005 and 0.3 mm pitch BGA; RF and microwave substrates to 30 GHz on Rogers and Megtron 6; rigid, flex, and rigid-flex builds; AOI, X-ray, and functional test on every board. Partners carry ISO 9001 and AS9100 certifications. The operation is small — four people, a garage, a vetted partner network — but the intent is to own the entire build from sourcing decision through final test.
That operational model creates a hiring signal different from a typical early-stage startup. The lone open role is not a generalist slot. It sits at the intersection of automated procurement, design-for-manufacturing review, and assembly execution: the three bottlenecks ProvenMetal says it automates. The candidate who fills it will step into a process that moves from BOM verification on day zero to tested boards shipping on day seven, with full lot traceability, MSL and ESD controls, and acceptance criteria agreed before production starts.
The Screen in Practice
ProvenMetal's public job posting for the Founding Engineer role describes the requirement plainly: an ambitious engineer with a background in electrical, electronic, or software engineering, ready to fully commit to building a unicorn. That breadth (three engineering disciplines for a single founding-engineer seat) reflects the actual work. The company automates three distinct bottlenecks in domestic PCB manufacturing: part procurement, design-for-manufacturing (DFM) review, and assembly. Each bottleneck sits at the intersection of hardware and software, and the founding engineer will touch all of them.
Will Carkner, CTO, previously shipped the PCB testing pipeline at Lumindt. That experience signals what ProvenMetal values: someone who has built the software that validates physical boards, not just designed the boards themselves. Johnny Doyle, CEO, came from IoT building-management systems, a domain where firmware, mechanical constraints, and supply-chain lead times collide daily. In the Dogpatch garage, the line between "electrical engineer" and "software engineer" dissolves. The job is to write the code that turns a customer's design files into a quoted, sourced, assembled, and X-ray-inspected board in five to seven days.
The research does not list a specific IPC certification or soldering standard as a hiring gate. Generic PCB-technician postings across the industry cite IPC-A-610 or J-STD-001, fluency with Altium Designer or Eagle, and hands-on rework with microscopes, multimeters, and oscilloscopes. ProvenMetal's public materials do not mention those. What they do mention is instant quoting, automated DFM review using Anthropic in zero-retention mode, and X-ray inspection of every board; all are software-driven workflows.
Hardware-test infrastructure is the other explicit thread. Carkner's Lumindt pipeline and the company's own X-ray-every-board policy point to a need for engineers comfortable with test automation applied to a manufacturing line.
The "any experience level, new grads welcome" line on the careers page is a filter for adaptability. Visa sponsorship and free hacker-house accommodation widen the aperture further. The company is recruiting nationally and internationally for a role that demands physical presence in San Francisco; boards are assembled on Lane Street, not in the cloud.
Fit Over Credentials
ProvenMetal's four-person team operates from a garage in Dogpatch, where the boundary between founder and early employee dissolves. The company's lone open role — Founding Engineer, $100K–$200K with 1–4% equity, new grads welcome — signals that cultural alignment outweighs credential depth. Doyle and Carkner built this operation by pivoting from Syncra Technologies after thirty-plus customer meetings and five letters of intent pointed the same direction: domestic fast-turn PCBs. They scrapped their original idea, booked flights to San Francisco, and proved customer demand in a week to win a second YC interview. That velocity ("maximised velocity" in Doyle's words) is the behavioral benchmark.
The YC selection process itself filtered for this trait. Vivian Midha Shen, their primary partner, saw a team that wound down a business, relocated five thousand miles, and generated proof in seven days. Carkner came from hydrogen battery experience at Lumindt; Doyle had shipped IoT building management systems. Neither fit a traditional manufacturing resume. ProvenMetal's hiring logic mirrors that pattern: demonstrated ability to move fast in ambiguous, hardware-constrained environments beats a perfect transcript.
"America is reshoring the chip. But we're ignoring the board that makes it work." (Will Carkner, July 2026 blog post)
That mission framing attracts a specific candidate profile. Defense, drone, and robotics customers choose ProvenMetal partly because ITAR compliance and supply-chain sovereignty are non-negotiable. The team "owns sourcing, fabrication, US assembly, and test" as a single unit. Cross-functional ownership is not a slogan; it's the only way five-to-seven-day turns happen with four people.
The equity range (1–4%) reinforces the founder-adjacent expectation. This is not a role for someone who waits for tickets. Practical experience carries weight in specific forms. Carkner's Lumindt stint and Doyle's IoT deployments meant they understood hardware iteration cycles from the customer side. ProvenMetal's target customers (hardware startups burning cash, defense contractors navigating compliance) face the same time pressure.
The garage origin story is not mythology; it's the operating model. Four people, one team, no handoffs.
How Candidates Win
ProvenMetal's founding engineer role sits at the intersection of electrical engineering, software automation, and manufacturing operations, a combination that reflects the company's core thesis: the bottlenecks in domestic PCB production are solvable with code. The job posting asks for an engineer matching the earlier description. That phrasing describes the daily reality of a four-person team running a garage operation in Dogpatch that sources components, manages fab partners, assembles boards, and ships tested units in five to seven days.
The company's own process makes the work visible: Phase 01 (Day 0–2) sources and verifies every part against the BOM; Phase 02 (Day 2–5) runs fabrication and assembly with vetted partners; Phase 03 (Day 5–7) tests every board and ships it. An applicant who can speak to MSL/ESD handling, lot traceability, AOI and X-ray inspection, or functional test fixture design signals they will not need months to become useful on the factory floor.
The software layer ProvenMetal is building to compress those phases automates the DFM review mentioned earlier, with a manual-review fallback for customers who prohibit external model processing. That detail, published on their site, reveals the stack: LLM-assisted design-rule checking, instant quoting, and a pipeline that turns Gerbers and BOMs into a build plan.
ProvenMetal's public customer logos — Sorcerer, Vortex Drones, Vernius, Earendil Robotics, Autonumy, Greypoint Industries, Kform, Biohub Chicago — cluster in drones, robotics, and defense-adjacent hardware. The founders have explicitly asked for "intros to drone companies that need hardware fast" and noted after an Actuators 2026 event that "we had the whole US drone supply chain in one bar."
Visa sponsorship is available, but the expectation is physical presence in San Francisco. The compensation band ($100K–$200K base, 1–4% equity) spans individual contribution to technical leadership.
Finally, do not treat the "new grads welcome" line as a lowering of the bar. It means the founders will teach domain-specific manufacturing knowledge to someone who demonstrates the raw engineering velocity and hardware intuition they need.
The Board That Ships
The garage in Dogpatch still ships boards in that timeframe. The screen still filters for the engineer who can keep that promise: not the one with the longest credential list, but the one who has already lived the loop of code, hardware, data, repeat. When the next revision lands on the line, the only question that matters is whether the person standing there can see the failure before it ships.
