Job summary

Monarch Quantum is seeking a Senior Photonics Process Development Engineer to build scalable packaging and tooling. You will drive end-to-end photonic assembly development from concept to production, collaborating with multi-disciplinary teams to ensure high yield and robust manufacturability.

You will design DOE studies, define process controls, transfer processes to manufacturing, and push for continuous improvements in yield and cost while adhering to cleanroom protocols.

Qualifications

• BS or MS in Optical Engineering, Electrical Engineering, Materials Science, Mechanical Engineering, Physics, or a related field.
• 8+ years of relevant experience in photonics or optoelectronic process development.
• 5–10 years of experience using manufacturing process equipment such as die bonders, wire bonders, vacuum reflow systems, active alignment platforms, or laser welding systems.

Responsibilities

• Participates in end‑to‑end development of photonic assembly processes from concept through production release.
• Create and execute the process development roadmap aligned with product and manufacturing goals.
• Design statistically rigorous experiments (DOE) to optimize process windows, robustness, and yield.
• Determine process control limits, qualification criteria, and acceptance metrics.
• Transition processes from R&D to pilot and full manufacturing scale.
• Process transfer to production, including equipment qualification (IQ, OQ, PQ).
• Work on yield improvement initiatives and root‑cause investigations for failures and reliability issues.
• Participate in establishing engineering standards, documentation, and best practices.
• Create process flows, work instructions, travelers, and training materials.
• Apply Design for Manufacturability (DFM) principles and perform tolerance analysis.
• Analyze and improve process capability (Cp/Cpk).
• Support qualification, reliability testing, and failure analysis (including FMEA).
• Perform precision fixtures, tooling, and mechanisms to enable repeatable assembly and alignment.
• Collaborate with mechanical engineers and equipment vendors to develop manufacturable solutions and automation.
• Ensure adherence to cleanroom protocols and contamination control practices.
• Perform other related duties as required.
• This position requires access to export‑controlled information. Employment is contingent upon the applicant being a U.S. person as defined by 8 U.S.C. § 1324b(a)(3).
