Firmware Engineer

Psi Quantum'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 approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industry, including partners like Global Foundries, 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'tfeel 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,Psi Quantum closed a $1 billion funding round that valued the company at $7 billion. In 2026, the U.S. Department of Commerce signed a $100 million Letter of Intent under the CHIPS and Science Act, followed by a $125 million agreement with DARPA under Stage C of its Quantum Benchmarking Initiative,Psi Quantum'smost valuable U.S. government agreement to date.

This year, we also broke ground on our utility-scale quantum computer in Brisbane, Australia, and continued building out our Chicago site. Victor Peng, our CEO, and co-founder Jeremy O'Brien, now Executive Chairman, lead a team and board that reflects how seriously the world is taking this build, joined this year by Intel's Lip-Bu Tan and Atomico's Niklas Zennstrom.

Psi Quantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies, including

Airbus,Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical, to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shift, and a path to mastering challenges that cannot besolvedany other way. The potential is enormous, and we now havethe funding,the government validation, andthe site sunder construction to make it real.

The Staff Firmware Engineer is a hands-on technical leader and firmware developer on Psi Quantum's Firmware team, within the Electronics organization. The role leads firmware architecture and development for quantum computing control systems, working closely with hardware, systems architecture, and software teams.

• Define system architecture and design in partnership with hardware and systems architecture teams; evaluate and select components to meet system requirements.
• Lead firmware-focused schematic reviews, identifying design risks and ensuring hardware supports system and firmware needs.
• Architect, develop, and validate firmware for quantum computing control systems and other research and development programs.
• Set technical direction for firmware design and implementation, and raise the quality of the team's work through design reviews and technical mentorship.
• Define and drive software interface specifications and deliverables across firmware, hardware, and systems teams.

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, or related field.
• Minimum of 10 years hand-on firmware development and architecture experience leading to a successful commercial product.
• Experience architecting solutions for multiple products and/or sets of control boards.
• Expert level firmware development in C/C++.
• Intermediate or advanced Python for control and test interfaces.
• Familiarity with build systems, version control, and test driven development.
• Schematic review and hardware debugging tools and techniques.
• RTOS, bare metal, and linux development experience.
• Communications protocol development and TCP/IP protocol implementations.
• Excellent verbal and written communication skills with an ability to communicate effectively to a variety of audiences ranging from senior leadership and technical experts to entry-level staff.
