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
Quantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum we’re building a general-purpose silicon photonic quantum computer to tackle these very problems.
What they're looking for
- Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Physics, or related technical field
- 7+ years of software engineering experience, with significant exposure to systems integration or platform architecture
- Proven experience designing and governing APIs (REST, gRPC, event-driven architectures) in complex, multi-tool environments
- Familiarity with data interchange formats (protocol buffers, avro, etc.)
- Experience integrating with data platforms (DataBricks, Tableau, etc.)
- Strong programming skills in Python (required) and at least one systems or backend language (Go, C++, Java, Rust, or similar)
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,...
