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 Senior System Integration & Optical Validation Engineer is responsible for leading the integration, system-level verification and validation (IV&V), and operational readiness of complex photonic quantum computing systems. This role develops integration strategies, test methodologies, validation processes, and deployment procedures to ensure integrated systems meet performance, reliability, and operational requirements. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- M.S. or Ph.D. in Optical Engineering, Electrical Engineering, Photonics, Physics, or a related technical field with 5+ years of relevant industry experience, or B.S. with 10+ years of equivalent experience
- Demonstrated expertise in developing system-level test strategies, verification methodologies, acceptance criteria, and experimental approaches for complex integrated systems
- Strong understanding of optical technologies, including lasers, fiber optics, photonic components, optical instrumentation, and measurement techniques
- Proven ability to troubleshoot multidisciplinary optical systems using structured experimental methods, quantitative data analysis, and systematic root-cause investigation
- Strong analytical, communication, and cross-functional collaboration skills, with the ability to make sound technical decisions in fast-paced engineering environments
- Experience with cryogenic systems or quantum technologies is highly desirable
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...
