Join our fast-paced and passionate team as a Photonics Scientist 3 – Reliability Engineering. As we scale, you will be instrumental in building our foundation from the ground up. This is a dynamic, hands-on role for a self-starter who thrives in a fluid startup environment. You'll have the opportunity to work on cutting edge technologies, work closely with leadership, and develop and implement engineering practices that support our mission and growth. Your key responsibilities are as follows:

Serve as subject matter expert for photonic systems within the Reliability Engineering team.

Identify laser and photonics system risks through component / system analysis and vendor discussions.

Design and execute hands-on short-term and long-term tests that systematically de-risk component, module, and system design decisions. Act as a champion for laser safety.

Collaborate closely with mechanical engineering to assist with the design of modular test stations that will allow for the long-term reliability testing of lasers, active/passive optical components, and modules.

Collaborate closely with optical and mechanical teams to understand system design and manufacturability and identify risks. Propose design changes and present trade-offs.

Work independently and in a team while overcommunicating with the manager, project engineer, and the teammates. Mentor junior engineers.

Execute complex engineering tasks involving planning, preparation, data/information collection, and analysis and decision-making in a process involving peer reviews and documentation of the results.

Use tenacity, patience, self-discipline, and passion for excellence to assure accuracy of execution schedule, data quality/integrity, conformance to company best practices, clarity in communication, and documentation.

Use every opportunity to grow competency through mentorship, curiosity, communication, exposure, and initiative.
