PsiQuantum is hiring: Production Engineer in Palo Alto

Overview

Join to apply for the Production Engineer role at PsiQuantum

PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering world-changing applications. We aim 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 potential advances across climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and more. Our architecture is based on silicon photonics and leverages high-volume semiconductor manufacturing processes; photons’ resistance to heat and EMI allows us to use existing cryogenic cooling systems and standard fiber connectivity. In 2024, PsiQuantum announced government-funded projects to support our Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois, backed by nations that understand quantum computing’s potential. We will build hardware and fault tolerant quantum applications that deliver industry-transforming results. We are seeking exceptional talent to join us on this extraordinary journey.

There is much more work to be done, and we are looking for exceptional talent to join us on this extraordinary journey.

Responsibilities

• Own and optimize polishing processes for optical and semiconductor components, ensuring high precision, low-defect surfaces.
• Support semiconductor and optical packaging operations, including die attach, wire bonding, fiber alignment, sealing, and final test.
• Collaborate with design, R&D, and equipment engineering teams to translate prototypes into scalable production processes.
• Develop and document process parameters, work instructions, and quality controls to ensure repeatability and reliability.
• Monitor production data to identify yield losses and drive root cause analysis and corrective actions.
• Introduce new tools, fixtures, and automation to improve process efficiency and throughput.
• Partner with suppliers and vendors to qualify new materials, components, and processes.
• Train technicians and operators on proper execution of polishing and packaging workflows.
• Champion continuous improvement initiatives in safety, quality, and productivity.

Experience/Qualifications

Required

• Bachelor’s degree in Mechanical Engineering, Materials Science, Electrical Engineering, Physics, or related field (or equivalent hands-on experience).
• 3+ years of experience in semiconductor manufacturing, precision optics, or advanced packaging.
• Strong knowledge of optical surface preparation (lapping, polishing, metrology).
• Hands-on experience with semiconductor/optical packaging processes (e.g., bonding, alignment, hermetic sealing).
• Familiarity with cleanroom practices, precision metrology, and process control.
• Strong analytical and problem-solving skills, with ability to drive root cause investigations.
• Excellent written and verbal communication skills.

Preferred

• Experience in photonics, fiber-optic components, or microelectronics assembly.
• Knowledge of adhesives, epoxies, and underfills used in semiconductor/optical packaging.
• Exposure to statistical process control (SPC), DOE, and Six Sigma methodologies.
• Experience with automation or custom tooling for packaging processes.
