Join our fast-paced and passionate team as a Senior Photonics Process Development Engineer. As we scale, you will play a key role in developing and maturing the processes that enable our products to move from concept to production. This is a highly hands-on role for someone who thrives in a dynamic startup environment and enjoys solving complex manufacturing challenges.

You’ll work closely with device, optical, mechanical, and manufacturing engineers to turn fragile photonic designs into robust, repeatable products. You’ll contribute to establishing best practices, improving yield, and supporting the transition from R&D to production.

Key Responsibilities

Lead hands-on process development for:

Wire bonding (Au, Al; ball and wedge)
Die bonding (epoxy, eutectic, and solder attach)
Vacuum reflow soldering (AuSn, SAC, indium, etc.)
Fiber splicing (fusion splicing, PM fiber alignment)
Optics attach and active alignment (lenses, isolators, fiber arrays)

Design and execute DOE experiments to improve yield, reliability, and performance
Support the transition of processes from R&D to pilot and early-stage manufacturing
Develop and maintain process flows, work instructions, and travelers
Perform root-cause analysis for yield loss and reliability issues
Collaborate with equipment vendors on tooling, fixturing, and process optimization
Support product qualification, reliability testing, and failure analysis efforts
Train technicians and manufacturing personnel on established processes
Contribute to continuous improvement of process control and manufacturability

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).

Experience:

BS or MS in Optical Engineering, Electrical Engineering, Materials Science, Mechanical Engineering, Physics, or related field
Typically 8+ years of relevant experience in photonics or optoelectronic process development
5–10 years of experience in photonics or optoelectronic process development

Core Skills

Wire bonding (ball and/or wedge)
Die bonding and solder attach processes
Vacuum reflow systems
Fiber splicing and fiber handling techniques
Precision optics attach and active alignment
Strong understanding of process control, yield improvement, and manufacturability
Comfortable working in lab and cleanroom environments
Clear and thorough documentation skills

Preferred Skills

Experience with laser diodes, PICs, modulators, detectors, or optical transceivers
Familiarity with hermetic packaging (butterfly, TO, or micro-optic packages)
Experience with active alignment systems and automation
Reliability testing experience (thermal cycling, HTOL, damp heat)
Knowledge of statistical process control (SPC) and manufacturing metrics
Experience supporting low- to medium-volume production environments

Startup Mindset

Comfortable taking ownership of projects while collaborating closely with a small team
Adaptable and resourceful in a fast-changing environment
Motivated to build, improve, and scale processes with a practical, hands-on approach continuously improve them

The expected annual salary range for this position is $125,000-$175,000.
