Senior Electro-Optic Packaging Engineer (Numerical)

Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world-changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.

By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.

PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier-1 semiconductor fabs such as GlobalFoundries where we leverage high-volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.

In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry-transforming results.

Quantum computing is not just an evolution of the decades-old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.

There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!

Job Summary:

The Senior Electro-Optic Packaging Engineer  will leverage advanced numerical simulation and analysis tools to guide the design of electro-optical packages, ensuring alignment with optical, thermal, electrical, and mechanical requirements.

This position requires an understanding of vacuum and cryogenic environmental requirements and their implications for electro-optical packaging. The engineer will provide design rules and simulation insights to drive thermal management solutions and support robust package designs.

Responsibilities:

• Utilize numerical simulation tools to interpret optical, thermal, electrical, and mechanical requirements, providing design directions for electro-optical packages.
• Assess and minimize the impact of assembly processes on PIC/EIC integrity by guiding process development through simulation insights.
• Guide BOM selection by providing simulation-driven inputs to material choices for optimal performance and reliability.
• Identify potential risks in proposed package designs or architectures and recommend mitigation strategies.
• Collaborate with experimental teams to validate and refine simulation models, enhancing their predictive accuracy.
• Develop and recommend design rules to ensure effective thermal management in package designs.
• Address and translate vacuum and cryogenic environmental requirements into electro-optical packaging solutions.
• Provide expertise in diverse package architectures, including traditional optical, 2.5D, and 3D packaging, ensuring designs meet performance, manufacturability, and reliability criteria.

Experience/Qualifications:

• Proficiency in numerical simulation tools for thermo-mechanical analysis and package design evaluation.
• Strong understanding of optical, thermal, electrical, and mechanical interactions within electro-optical packages.
• Familiarity with assembly processes such as die attach, optical coupling, underfilling, and fiber alignment, and their impact on PIC/EIC performance and reliability.
• Experience with BOM selection and optimization through simulation-driven insights.
• Knowledge of risk assessment techniques such as DFMEA and experience in driving risk mitigation plans.
• Hands-on experience with thermal management solutions and their implementation in package designs.
• Expertise in vacuum and cryogenic environments and their implications for packaging materials and architectures.
• Familiarity with traditional optical, 2.5D, and 3D package architectures, including their unique challenges and solutions.
• Familiarity with reliability requirements and testing.
• Engineering degree in Mechanical, Electrical, Materials Science, or related fields (BSc with 6+ years of experience, MSc with 3+ years, or PhD).
