Principal Engineer, Laser Module Architect

Ayar Labs • San Jose, CA

11h • Onsite

About The Position

Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models. Backed by industry giants like NVIDIA, Mediatek, AMD and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next-generation AI scale-up architectures. We are seeking a highly experienced and forward-thinking Laser Module Architect to define and drive next-generation laser technologies and system architectures. This role sits at the intersection of innovation and execution—shaping long-term technology strategy while enabling near-term product success. The ideal candidate brings deep expertise in laser physics, system design, and cross-functional leadership to translate emerging technologies into scalable, manufacturable solutions.

Requirements

• MS in Electrical Engineering, Physics, Photonics, or related field
• 10+ years of experience in laser design, optical systems, or photonics-based products
• Deep understanding of laser architectures (e.g., DFB, EML, external cavity lasers, integrated lasers) and system-level trade-offs
• Strong experience in modeling and simulation of laser systems and optical links
• Proven track record of architecting and delivering complex hardware systems from concept to production
• Experience working across hardware, firmware/software, and system teams

Nice To Haves

• Ph.D.
• Experience with silicon photonics integration and co-packaged optics
• Familiarity with high-speed optical communication systems and standards
• Background in reliability, manufacturing, and yield optimization for laser-based products
• Experience in semiconductor or optoelectronics startup

Responsibilities

• Lead system-level architecture development, converting product requirements into robust, scalable laser module solutions
• Develop and own trade-off frameworks across performance, cost, reliability, manufacturability, and power to guide design decisions
• Partner closely with Product Management to align specifications with market needs, while anticipating future platform evolution
• Collaborate with Laser HW, FW/SW, silicon photonics, packaging, and system teams to deliver cohesive module architectures
• Guide modeling, simulation, and early prototyping efforts to de-risk new technologies and validate architectural choices
• Establish design guidelines, reference architectures, and best practices to enable reuse and scalability across multiple product generations
• Act as a technical leader and mentor, influencing engineering direction across teams and driving alignment on critical decisions
• Engage with external partners, vendors, and research communities to stay at the forefront of laser innovation
• Define and drive the long-term laser technology roadmap, identifying and evaluating emerging architectures, components, and integration approaches
