PsiQuantum is on a mission to build the first commercially useful quantum computer to solve humanity. Backed by Founders Fund and Redpoint.
About the role
The Director, Platform & System will define the strategy for delivering a complete, integrated product that combines PsiQuantum’s photonic engine with partner-built systems and components. This role will own the system-level requirements, architecture, delivery model, and cross-subsystem trade-offs required to bring the product from specification through prototype and production.
What they're looking for
- 10+ years hardware systems engineering, 3+ directing system architecture for a rack-mounted networking or datacenter product that shipped.
- Direct command of datacenter hardware constraints: rack unit budgets, airflow, power delivery, front-panel density, serviceability, environmental standards.
- Took a system from specification through prototype and a partner or contract-manufacturer build.
- Familiar with datacenter cabling and the realities of high-density front-panel port counts.
- Writes specifications engineering teams can actually build against.
- Zone 1 - Bay Area and NYC
More about this role
PsiQuantum's mission is to build the first useful quantum computers: machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.
Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry, including partners like GlobalFoundries, we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don't feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.
That approach has since been tested at the highest level of scrutiny the U.S. government applies to emerging technology, and it has held up. In 2025, PsiQuantum...
