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 the Senior Applications Lead, Defense, you will help define and advance PsiQuantum’s defense and national security applications strategy. Sitting in the Industry Applications team, you will partner closely with Business Development, Applications, Algorithms, Software, and other technical teams to translate defense and national security needs into credible quantum computing opportunities.
What they're looking for
- Significant experience in the U.S. defense industry, national security, intelligence, aerospace, or adjacent government technology ecosystem
- Ability to obtain and maintain a U.S. Government security clearance required, active clearance (TS/SCI) preferred
- Ph.D. required in physics, engineering, applied mathematics, chemistry, materials science, or a related technical field
- Familiarity with quantum computing, quantum algorithms, high-performance computing, AI, semiconductors, or other technologies preferred
- Excellent written and verbal communication skills, including experience preparing briefings, proposals, white papers, conference materials, or customer-facing technical content
- Self-starter with strong cross-functional collaboration skills and the ability to thrive in a fast-paced environment with high ambiguity and evolving priorities
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,...
