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
As an integral part of the team developing a photonic quantum computer, the Staff Test Software Engineer will own the software that drives automated testing, calibration, and data acquisition across our fleet of electro-optical test stations including the sequencing, measurement, and instrument-control code that runs on the test stations built by our hardware test automation team.
What they're looking for
- BS in Electrical Engineering, Computer Science, Physics, or related field with 8+ years of relevant experience (MS with 6+ years, or PhD with 3+ years)
- Strong Python skills, including asynchronous programming
- Hands-on experience building automated test/measurement software with instrument control (SCPI/VISA/GPIB)
- Working knowledge of electrical, optical, or electro-optical measurement concepts
- Experience debugging distributed or fleet-scale systems
- Comfortable working at the boundary between software and hardware
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.
In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago,...
