Responsibilities
- Own the Diode Advance Program end-to-end: scope, schedule, budget, risks, and deliverables across all work packages, including next-generation development, exploratory R&D, manufacturability confirmation, subsystem cost reduction, cost modeling, and beam-shaping optimization.
- Serve as primary technical interface with external research partners on diode bar development, overseeing both an evolutionary performance track and a high-risk/high-reward exploratory concept.
- Coordinate manufacturability reviews with multiple diode manufacturers; manage separate design-review cycles to confirm that R&D designs can be produced at commercial scale. Maintain the confidentiality firewall between competing manufacturers.
- Drive power-supply and cooling cost-down: manage collaborations with industrial partners to benchmark, redesign, and prototype improved driver electronics and cooling subsystems; scout and onboard additional partners.
- Provide technical inputs to the diode cost model covering the full stack and translate cost targets into engineering requirements.
- Communicate program progress, risks, and decisions clearly to executive leadership and all internal and external stakeholders.
Requirements
- Master's degree (or higher) in Mechatronics, Electrical Engineering, Physics, Systems Engineering, or a related field.
- 3+ years of experience in systems engineering, product development, or technical project management in a multi-physics environment (thermal, electrical, optical, mechanical).
- Demonstrated ability to manage multi-partner R&D projects, coordinating external research institutes, industrial suppliers, and internal teams simultaneously.
- Hands-on experience translating R&D outputs into manufacturable products: design-for-manufacturing, supplier coordination, and prototype-to-production transitions.
- Strong cost and manufacturability mindset
- Fluency in English
- Self-directed, structured, and comfortable operating in a fast-moving startup
- Preferred: Experience with high-power diode lasers
