Who Gets Hired, and Where They Land
PsiQuantum's $1 billion Series E, closed in 2025, made it the best-funded pure-play photonic quantum company in the world — and its hiring now reflects a shift from research to semiconductor-scale execution. The company's engineering focus (silicon photonics manufactured at GlobalFoundries' Fab 8 in Malta, New York; fusion-based quantum computation with fixed routing and constant-depth operations; control electronics co-located with qubits in modular packaging; and a software platform (Construct) for fault-tolerant algorithm development) maps directly to teams scaling across Milpitas, Palo Alto, Chicago, the UK's Daresbury Laboratory, and the Moreton Bay site in Queensland. Headcount passed 500 in 2026, backed by government partnerships with DARPA, AFRL, and the Australian and U.S. federal governments.
The candidate profile centers on engineers and scientists who have moved hardware from prototype to volume. Active requisitions include Principal Power Systems Architect for Quantum Infrastructure, Principal Characterization–Failure Analysis Engineer, Staff Hardware Design Engineer, Manager of Optical Process Engineering, and Staff Digital Design Engineer. These roles sit inside distinct but intersecting groups: the silicon photonics team designing the Omega chipset; the cryogenic systems team building cabinets that support hundreds of chips; the control electronics team integrating classical logic inside the cold package; the process engineering team qualifying wafer-level yield with GlobalFoundries; the characterization and failure-analysis group closing the loop between fab data and design rules; and the quantum architecture team translating FBQC's fusion networks (6-ring and 4-star topologies with published loss thresholds of roughly one in ten fusions and one in forty photons — Bartolucci et al.'s Nature paper reports 10.4% fusion erasure and 2.7% photon loss thresholds) into system-level error budgets. The pay breakdown for these roles follows in the next section.
Cross-disciplinary fluency is non-negotiable. A photonics designer must understand how waveguide loss propagates through a fusion measurement. A cryogenic mechanical engineer must account for the thermal budget of control ASICs sitting millimeters from the qubit plane. A digital design engineer writing RTL for the control stack must know the timing constraints imposed by feed-forward in a ballistic FBQC scheme. The company's own technical communications emphasize that "every qubit only needs to see a small constant depth of physical components in its lifetime" and that fixed routing "eliminates the need to be able to switch between multiple possible configurations" — design choices that only work if hardware, firmware, and architecture teams share a common error model.
Hiring patterns reflect this. The Milpitas cluster (power systems, characterization, hardware design, optical process engineering) is the integration hub where fab output meets cryogenic packaging. Palo Alto hosts digital design and the Construct software effort. The Chicago and Australian sites are building infrastructure teams in parallel with the hardware ramp. DARPA's advancement of PsiQuantum to the final phase of the US2QC program, the $125 million agreement announced in July 2026, and the CHIPS Act letter of intent for up to $100 million in proposed incentives all signal that the hiring trajectory is tied to government-milestone delivery, not just research milestones.
The through-line: PsiQuantum recruits for execution in high-precision environments where semiconductor process control, cryogenic engineering, and quantum architecture intersect. The teams are organized around that intersection.
The Pay Picture
PsiQuantum's compensation reflects a company that has moved past early-stage risk into capital-intensive execution — backed by the Series E, the DARPA contract, and government partnerships worth hundreds of millions more. Zero G Talent's board data, drawn from 54 salaried roles posted directly to the site, (Zero G Talent's figures put the band at $100k–$236k, median $186k) shows a base salary band of roughly $100k–$236k with a median of $186k.
| Role | Location | Base Salary Range (USD/year) |
|---|---|---|
| Principal Power Systems Architect, Quantum Infrastructure | Milpitas, CA | $239,500 – $281,400 |
| Director, Investor Relations | Palo Alto, CA | $218,600 – $256,800 |
| Principal Characterization–Failure Analysis Engineer | Milpitas, CA | $208,300 – $244,700 |
| Staff Hardware Design Engineer | Milpitas, CA | $201,400 – $236,600 |
| Manager, Optical Process Engineering | Milpitas, CA | $201,400 – $236,600 |
| Staff Digital Design Engineer | Palo Alto, CA | $201,400 – $236,600 |
Location differentials are modest; Milpitas and Palo Alto roles sit in the same bands, which suggests PsiQuantum prices to the Bay Area market rather than adjusting for the 15-mile gap. That aligns with operational reality: the Milpitas site hosts the primary integration and test labs (cryogenic probe stations, high-speed optical characterization), while Palo Alto houses architecture, digital control systems, and software teams. Candidates relocating from lower-cost regions should not expect a geographic adjustment; the band is the band.
Equity is where the negotiation lives. The Series E raised $1B at a valuation implying meaningful paper gains for early holders, but the cap table now includes sovereign wealth (Australian Commonwealth and Queensland governments, A$940M committed April 2024), DARPA (non-dilutive contracts), and CHIPS Act incentives (up to $100M LOI signed 2026). Each tranche adds liquidation preferences. A staff engineer joining today should model equity as a long-duration option on a utility-scale machine — not a four-year flip. The board data doesn't capture refresh grants or performance multipliers.
Bottom line: cash compensation is competitive for deep-tech hardware. The trade is access to a production silicon-photonic flow at GlobalFoundries Fab 8, cryogenic integration at scale, and a roadmap that has cleared DARPA's most rigorous benchmarking gauntlet. If that scope matches your career vector, the band is negotiable at the margins — especially for candidates who bring tape-out experience on 300mm SOI or have commissioned dilution refrigerators in a fab-adjacent environment.
Inside the Filter
PsiQuantum does not publish a step-by-step interview playbook, and no first-hand accounts from recent candidates appear in the public record. What the research shows through job postings, the technical roadmap, and leadership composition is the evidence base the process must filter for.
The roles currently listed all sit at the intersection of semiconductor fabrication, cryogenic packaging, and photonic control systems. Each posting specifies a salary band ($201k–$281k) consistent with senior individual-contributor or technical-lead scope. That compensation level implies a hiring bar calibrated for engineers who have already shipped complex hardware in high-precision environments.
The company's public narrative reinforces what the roles demand. Co-founder Jeremy O'Brien described the last decade as "several years and several hundred million dollars getting into [the semiconductor] industry... a decade and a billion dollars let's say to be at the point where we're mass manufacturing the chips." That trajectory, from university research through foundry qualification at GlobalFoundries' Fab 8 to the Omega chipset announced in 2025, means every hire must operate inside a flow spanning process development, yield analysis, cryogenic test, and system integration.
Leadership hires signal the same priority. The July 2026 appointments of Rob Soderbery as Executive Vice President and Sriram Sitaraman as Chief Information Officer, announced alongside Victor Peng's confirmation as CEO, brought in executives with experience scaling engineering organizations. Their mandate is "scaling engineering, operational, and commercial capabilities" (language straight from the company's press release), telling you the interview loop evaluates not just technical depth but the ability to build and run teams that execute at foundry pace.
Dani Kleinman, Chief People Officer since at least 2026, oversees a people function across Palo Alto, Milpitas, New York, the UK Daresbury site, and the new Illinois Quantum and Microelectronics Park. The geographic spread means the process also tests for cross-site collaboration — candidates interview with counterparts in fabrication, packaging, and cryogenics groups who will depend on each other's deliverables.
No public source documents the exact number of interview stages, panel composition, or specific rubrics. What the grounded evidence supports is this: the filter is the work itself. Partnerships with Lockheed Martin, Mercedes, and Airbus; the DARPA QBI contract; in-house barium titanate development — each represents a milestone that cannot be met by theoretical contribution alone. The hiring process, whatever its formal structure, is designed to admit engineers who have already demonstrated they can deliver inside that kind of program.
Three Nodes, One Thread
PsiQuantum's physical footprint reflects its founding thesis: the company does not own a fab, but operates like a tenant that has learned to push a commercial CMOS line far beyond its standard process window. The result is a three-node network (headquarters in Palo Alto, a hardware integration campus in Milpitas, and a dedicated photonics flow at the New York fab), each solving a different slice of the problem a fault-tolerant photonic quantum computer presents.
Palo Alto houses architecture, algorithms, and software teams, including the group that shipped the Construct SDK. The site functions as the systems-engineering brain: it defines the logical qubit layout, the error-correction cycle time, and the control-plane latency budget the hardware must meet. Because the machine's interconnect is optical, the Palo Alto team also owns the link-level simulation models that translate a circuit description into a schedule of photon routing, loss budgets, and detector timing — models validated against silicon test structures before a single wafer ships north.
Milpitas, roughly ten miles southeast, is where those models meet cryogenics and packaging. The board's live postings (Principal Power Systems Architect, the principal characterization engineer, the staff hardware designer, the optical process manager) all sit in Milpitas, and the role titles map directly to the infrastructure there: dilution refrigerators with custom optical feedthroughs, wafer-level probe stations, and a low-volume assembly line bonding detector arrays, multiplexers, and routing chips into the multi-chip modules that become a "quantum cabinet."
The third node is not PsiQuantum's at all — it is GlobalFoundries Fab 8, a 300 mm CMOS line in upstate New York where the company has spent more than $100 million and six years qualifying a silicon-photonics process that did not exist in any PDK when the partnership began. The chips are "silicon chips that move light instead of electricity," as the company describes them. PsiQuantum engineers work on-site at Fab 8 during critical lot runs, co-owning the metrology recipes and yield models that feed back into the Palo Alto architecture. The arrangement is contractual, not acquisitive: the company "works within the constraints of a big fab and an existing supply chain" rather than demanding atomic-scale process changes that would break the line's economics.
What ties the three nodes together is a single digital thread. A wafer lot processed in Malta ships to Milpitas for cryogenic probe and module integration; the resulting characterization data flows to Palo Alto to update the system model and the Construct compiler's hardware-aware scheduling pass. The loop closes when a new process variant (a lower-loss grating coupler, a faster phase shifter) is designed in Palo Alto, taped out through the Fab 8 flow, and validated in Milpitas. That cadence, not any one facility, is the infrastructure that lets a photonic approach chase millions of qubits on a semiconductor timeline.
Who Stays, Who Leads
The people who stay and advance at PsiQuantum share a recognizable profile: they treat the gap between a lab demonstration and a manufactured, deployable system as an engineering problem, not a research question. The company's own language ("moving quantum computing out of the lab and into utility-scale infrastructure") filters for engineers and scientists who have already operated in that gap. Founders Jeremy O'Brien, Terry Rudolph, Peter Shadbolt, and Mark Thompson spent more than a decade in academic photonics at Bristol and Imperial before incorporating; the hiring pattern since then has favored candidates who can translate that depth into production flow.
Technical breadth across the stack is non-negotiable. A given week might require a photonics engineer to debug edge-coupling yield at the Malta fab, then coordinate with the Milpitas PsiFactory team on wafer handling, while the Daresbury PsiLabs group validates cryogenic cabinet thermal models at 2 K. The Technology Review profile notes that PsiQuantum now produces several detector chips per day — a cadence that only exists because the design, fab, packaging, and test loops are closed inside the same organization.
Government partnership fluency matters more here than at most venture-backed hardware companies. PsiQuantum is one of two companies (with Microsoft) to reach the final phase of DARPA's Quantum Benchmarking Initiative, holds a $125 million QBI contract, a $22.5 million AFRL agreement (USAspending federal awards data records a $22.5M DoD award), and the CHIPS Act incentive letter. The Australian Commonwealth and Queensland governments have committed A$940 million for the Moreton Bay Central site.
The software-hardware boundary is unusually tight. PsiQuantum's Construct platform, described as "the industry's first comprehensive platform designed to help enterprises, governments, and researchers create fault-tolerant quantum algorithms", is developed in parallel with the Omega chipset. Application engineers work with Mercedes-Benz on battery chemistry, Airbus on fluid-dynamics simulation, and Boehringer Ingelheim on molecular modeling. The December 2024 Airbus collaboration paper showed only moderate speedup on classical benchmarks, and outside experts (Andrew Childs, Dominic Berry) noted the algorithm needs further acceleration and lower error rates.
Execution under aggressive, public milestones is the daily rhythm. The company broke ground at Moreton Bay Central in June 2026 targeting "hardware-ready" status in 2027; the Chicago IQMP site is on a parallel track. Victor Peng's appointment as CEO in 2026, followed by Rob Soderbery (EVP) and Sriram Sitaraman (CIO), signals a shift from pure R&D to scaled delivery.
Cross-disciplinary communication is tested explicitly. A photonics process engineer must explain yield loss to a quantum architect who thinks in logical error rates; a control-systems engineer must specify noise floors the ASIC team can hit; the Construct team must expose compiler primitives the FBQC architecture can execute natively. The company's own site lists "manufacturability," "networking," "cooling power," and "control electronics" as co-equal pillars; no single discipline owns the critical path.
Finally, tolerance for opaque progress. Scott Aaronson noted it is "very hard for an outsider to evaluate" PsiQuantum's advances; Joe Altepeter, former DARPA QBI program manager, said in March 2025 he is "more optimistic now than at any point in the past 10 years." The company publishes selectively (major contracts, groundbreakings, the Omega chipset announcement) but does not release interim qubit-count or fidelity dashboards. Employees who thrive are internally motivated by technical milestones their friends and former professors cannot yet verify. They build the cabinet, the chip, the decoder, and the algorithm knowing the first utility-scale demonstration is still ahead, and they treat that uncertainty as the job.
