Manager, Passive Components

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. 

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, PsiQuantum 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, PsiQuantum's most 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 Zennström. 

PsiQuantum 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. It represents a fundamental shift, and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we now have the funding, the government validation, and the sites under construction to make it real. 

Job Summary:

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. 

We are looking for an energetic, highly motivated Photonics Engineer who will be responsible for the design, optimization, integration, and validation of novel photonic structures, devices, and subsystems for a linear optic quantum computer (LOQC).

We’re looking for a creative and innovative individual with strong fundamentals in the design, optimization, layout, and fabrication of integrated photonic devices. This role is focused on leading a group that is pushing the boundaries of high-performance integrated photonic components and circuits. The role requires excellent programming skills, experience with commercial electro-magnetic simulation packages, experience with photonic optimization techniques, and deep knowledge of the design and validation of integrated photonic components. Experience with python based layout tools and foundry tapeouts are highly desirable.

Responsibilities:

• Leads the development of passive photonic components.
• Interacts with device, hardware and software design teams to assist in overall development of Photonics and Quantum Optics photonic systems and devices.
• Leads the development of simulation automation techniques and infrastructure to support photonic device design, model development, and performance validation.
• Leads the development of a photonic device library and process design kit (PDK) for passive photonic components.
• Supports foundry tapeouts with photonic device design, design of experiments, layout, device validation, data analysis, failure mode analysis, and troubleshooting.
• Provides multi-disciplinary support to component and systems teams by resolving technical issues associated with components, parts, products, or systems.
• Applies quantitative analysis in determining root cause of highly technical problems and proposes, develops and implements solutions for corrective action.

Experience/Qualifications:

• PhD or equivalent in Electrical, Computer Engineering, Material Science, Physics.

Experience

• 10 years of relevant work or academic research experience in integrated photonics.
• 2 years of project and/or people management experience.

Knowledge, Skills and Abilities

• Strong leadership and organizational skills.
• Strong fundamentals of the design and characterization of photonic devices and circuits.
• Strong fundamentals in electro-magnetic theory.
• Extensive experience with simulation platforms, particularly Lumerical, for designing and simulating photonic devices and circuits.
• Proven team player with an ability to work effectively across departments, sites, time zones.
• Excellent verbal and written communication skills.
• Strong analytical and detail oriented problem-solving skills.
• Proven experience executing cross-department complex projects.
