AI Product Engineer, FW​/SW

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.

This is a senior individual contributor role operating at the intersection of silicon photonics, embedded systems, electronics, controls, and system software
. The engineer will be responsible for translating photonic device and system requirements into robust control algorithms, firmware, APIs, diagnostics, and system-level software.

The ideal candidate has previously developed firmware and software for complex embedded hardware systems
, understands closed-loop control and real-time system behavior
, and is comfortable working directly with hardware during bring-up, characterization, debugging, and productization.

• Architect, develop, and maintain embedded firmware for control and management of silicon photonics products.
• Develop firmware that interfaces with photonic devices, ASICs/FPGAs, DACs, ADCs, temperature sensors, power-management devices, and other board-level electronics.
• Implement closed-loop control algorithms for parameters such as optical operating points, temperature, power, bias, alignment, switching state, and other device-specific control variables.
• Understand system dynamics, stability, convergence, calibration, tolerances, noise, drift, and failure modes when designing control loops.
