Who gets hired and onto which teams
Equal1, a quantum computing company founded in 2017, listed eight to nine open roles across six sites in five countries as of October 2026, roughly half of them engineering positions at the center of its silicon-spin-qubit architecture. This guide maps who gets hired, what the work pays, and how the interview process works, drawn from the company's posted roles, its careers pages, and public data.
The company operates from Dublin headquarters, California (Fremont), Sherbrooke, Timișoara, Delft, and Japan. Engineering roles break into quantum (three positions), backend, product, industrial engineering, and operations, a spread that reflects a hardware-first company moving toward system integration and deployable product.
The quantum roles define the core. A Spin Qubit Calibration Engineer works on qubit characterization and control, with postings showing Sherbrooke and Dublin locations. A Quantum Error Correction Lead or Senior Quantum Error Correction Scientist, posted in Dublin with additional locations in Delft and Sherbrooke, targets the fault-tolerance layer. A Software Stack/Framework Engineer in Timișoara builds the bridge between quantum hardware and the developers who will use it. These sit at the center of Equal1's chip-based approach.
Around that core, the company hires for the physical and mechanical systems that make the chip work in practice. A Cryogenic Systems Engineer and a Junior Mechanical CAD Engineer/Designer, both in California (Fremont), handle the dilution-refrigerator environment and the mechanical design of the integrated package. A Technical Program Manager for Cryomechanical & Quantum System Integration, also in Fremont, owns the cross-disciplinary schedule that brings silicon, cryogenics, and control electronics together. An Advanced Packaging & Integration Lead, listed with a Dublin anchor and Delft presence, focuses on the heterogeneous integration that distinguishes Equal1's architecture.
The non-technical hires signal maturity. A Head of People in Dublin, posted six months ago, and an HR role in the Alion data suggest the organization is formalizing its talent function. A speculative-applications slot for quantum computing, open for seven months across Dublin, Delft, Timișoara, and Sherbrooke, acts as a standing funnel for candidates who don't fit a current requisition but match the company's long-term needs.
Seniority skews toward leadership and experienced individual contributors. Alion's snapshot shows two Lead roles, one Head+, one Staff+, and one Junior. Engradar's broader set reads five unspecified, two Senior, one Director, one Junior. The first-party board on Zero G Talent confirms the pattern: the Advanced Packaging & Integration Lead, the Quantum Error Correction Lead/Senior Scientist, the Head of People, and the Technical Program Manager all carry scope implying ownership of a workstream or team. The Junior Mechanical CAD Engineer/Designer is the lone early-career posting.
Seven of the eight current listings have been open more than 90 days (median 97 days on Engradar; Alion reports median age 183 days with 7 of 8 roles over 90 days). Alion's truth index scores the board a B with 100% of checked roles flagged as stale. The roles are real — 0% ghost listings, 0% reposted — but they stay open until the right intersection of specialization and learning capacity appears.
The team a candidate lands on is determined by that intersection. Quantum hires join the physics and control group. Cryogenic, mechanical, and packaging engineers sit in the hardware integration group. The software stack engineer bridges to the product organization. The TPM and the Head of People operate across all of them. There is no generalist track; every open role maps to a specific technical risk the company is retiring on the path to a compact, affordable quantum computer.
What it pays
Equal1 does not publish salary bands or equity grant sizes in its public job postings. The nine roles currently listed on its Ashby board — spanning quantum error correction, cryogenic systems, advanced packaging, mechanical CAD, technical program management, people operations, and software framework engineering — carry no compensation metadata. That silence is typical for a deep-tech company of this size operating in a niche where peer benchmarks are thin.
Alion provides estimated annual ranges for seven of the eight roles it tracks (all marked "Estimated"):
| Role | Location | Estimated Range (USD/yr) |
|---|---|---|
| Spin Qubit Calibration Engineer | Dublin | $74k – $201k |
| Advanced Packaging & Integration Lead | Dublin • Delft | $94k – $223k |
| Junior Mechanical CAD Engineer / Designer | San Jose | $66k – $124k |
| Technical Program Manager – Cryomechanical & Quantum System Integration | San Jose | $160k – $288k |
| Head of People | Dublin | $91k – $219k |
| Quantum Error Correction Lead / Senior Quantum Error Correction Scientist | Dublin • Delft | $63k – $173k |
| Speculative Applications (Quantum Computing) | Dublin • Delft • Timișoara | $62k – $170k |
The Software Stack / Framework Engineer in Timișoara shows no estimate. These figures are Alion's modeled estimates, not company-published bands. The ranges are wide, reflecting the variance in seniority, location, and candidate leverage typical at this stage.
Equity mechanics follow venture-backed deep-tech norms for a company with Equal1's investor base (European Innovation Council, Atlantic Bridge, Elkstone, Enterprise Ireland, TNO, ISIF, Matterwave Ventures, and others listed on equal1.com). The company's leadership has described a "fabless semiconductor" long-term model (Jason Lynch, QC Ware interview), implying equity upside tied to a liquidity event rather than secondary markets. Specific grant sizes, vesting schedules, and instrument types (EMI, BSPCE, ISO/NSO) are not public.
Geographic differentials are real: roles are posted in Dublin, Delft, Sherbrooke, Timișoara, and Fremont, each with distinct labor markets. Candidates can move from qualitative to quantitative at the recruiter screen with three specific questions: (1) "What is the base salary band for this role at this location?" (2) "What percentage of the fully diluted option pool does this grant represent?" (3) "What is the current 409A / fair-market-value strike price and when was it last set?" If the recruiter cannot or will not answer, that signals the maturity of the compensation function; not a reason to walk away, but it does mean the offer conversation will be the first time real numbers appear.
How the hiring process works and what gets candidates through it
Equal1's public careers page keeps the process description broad: the company says it seeks "highly talented and energetic team members" who are "passionate about quantum technology" and ready to "tackle groundbreaking challenges." The company does not publish a detailed, stage-by-stage interview framework on its own site.
No public source documents Equal1's specific interview process. The Equal Experts consultancy (a separate company) publishes a four-step framework on its site, but there is no evidence Equal1 uses that process. Glassdoor shows one review for Equal1, insufficient to reconstruct a process. Candidates should expect a technical screen relevant to the role (quantum error correction, cryogenic systems, advanced packaging, mechanical CAD, or program management), likely a take-home or live technical exercise, and conversations with future teammates and hiring managers, but the exact steps, timeline, and rubric are not in the public record.
Application signal. The live board shows six open roles across Dublin and California on Zero G Talent's board as of October 2026, with additional roles on Ashby and Alion. Tailor materials to the specific discipline: a Quantum Error Correction Lead needs a track record in fault-tolerant protocols and silicon spin qubits; a Cryogenic Systems Engineer needs dilution-refrigerator integration experience; a Technical Program Manager needs cross-domain hardware/software delivery proof. The roles lead with demonstrated work on the relevant problem: tape-outs, fridge commissioning, surface-code simulations matched to data, mechanical designs that survived thermal cycling.
Where the work happens
Equal1 operates from six locations: Dublin (HQ), Delft, Sherbrooke, Timișoara, Fremont, and Japan. Zero G Talent's board lists six recent postings tied to Dublin and Fremont, and the distribution reveals how the company splits its quantum-computing stack.
Dublin carries three roles on the first-party board: Advanced Packaging & Integration Lead, Quantum Error Correction Lead / Senior Quantum Error Correction Scientist, and Head of People. Packaging and error correction sit at the heart of Equal1's silicon-spin-qubit approach; both demand close collaboration between process engineers, device physicists, and fab partners running CMOS-compatible flows.
Fremont carries three postings on the board: Junior Mechanical CAD Engineer / Designer, Cryogenic Systems Engineer, and Technical Program Manager – Cryomechanical & Quantum System Integration. These roles point to the dilution-refrigerator infrastructure, the wiring and thermal engineering that connects the quantum chip to room-temperature control electronics, and the program-management discipline that stitches the cryogenic subsystem into the full-system bring-up.
The split mirrors a recognized pattern in solid-state quantum hardware: quantum-information science (error correction, architecture, algorithm-compiler co-design) clusters where theoretical talent and university partnerships live, while cryogenic packaging and system bring-up clusters where test infrastructure, fridge farms, and mechanical fabrication capacity live. Dublin hosts university collaborations (UCD is noted on the company site); Fremont accesses the Bay Area's cryogenics supply chain and mechanical engineering talent.
What the research does not show — because the board data captures only six live postings — is whether either site runs cleanroom processing, whether a third site exists for wafer fabrication, or how the hubs coordinate day to day. Employee reviews on Glassdoor and SimplyHired number only one each, so there is no public qualitative picture of site culture, commute, or remote-work norms. The company's own careers page lists all open roles and locations. Candidates should verify directly with recruiters whether travel between sites is expected for their function, and whether a fab-access site (likely a partner foundry) factors into the role.
Who thrives here
The roles Equal1 posts reveal the profile of people who match the work. The company builds silicon-based quantum processors — a stack spanning quantum error correction theory, cryogenic packaging, mechanical design at millikelvin temperatures, and program management to ship it across five time zones. The six live postings on Zero G Talent's board as of October 2026 make that stack explicit: a Quantum Error Correction Lead in Dublin, an Advanced Packaging & Integration Lead in Dublin, a Cryogenic Systems Engineer in Fremont, a Technical Program Manager for cryomechanical and quantum system integration in Fremont, a Junior Mechanical CAD Engineer in Fremont, and a Head of People in Dublin. Each role sits at a different layer of the same problem: turning a quantum chip into a manufacturable, operable system.
The postings emphasize this. The Junior Mechanical CAD Engineer role asks for production CAD experience and a Master's degree. The Quantum Error Correction Lead asks for 5+ years' experience, a PhD, and Python. The Advanced Packaging & Integration Lead asks for 7+ years' experience, a Master's degree, and Ansys HFSS. The Cryogenic Systems Engineer asks for millikelvin cryocooler design, thermodynamic and gas-flow concepts for He-4/He-3 cycles, and Joule-Thomson turbocompressor experience. The Head of People asks for HR operations leadership, scalable processes, multi-jurisdiction compliance, and employee experience. The Technical Program Manager asks for 10+ years' experience managing end-to-end technical programs for cryomechanical and quantum system integration.
The multi-site footprint selects for people who communicate asynchronously by default. A packaging decision in Dublin affects cryogenic wiring in Fremont; a mechanical tolerance in Timișoara changes the thermal model in Sherbrooke. The Technical Program Manager role exists because those dependencies are real and cross-functional. Engineers who wait for a meeting to resolve a blocking question lose weeks. The ones who ship write the trade-off document, tag the owners, and propose a decision by end of day.
The company's own careers page emphasizes "quantum computing as deployable rack infrastructure" and "silicon-based quantum computer technology." The people who stay are the ones who treat that phrase as an engineering commitment. They know the foundry run schedule. They know the lead time on a custom cryogenic cable. They know the error budget allocation across control electronics, packaging, and qubit coherence. And they know that the only way to hit the next milestone is to hand off clean interfaces to the team in the next time zone — and to demand the same from them.
