Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world's first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads. Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter! If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders. Lightmatter is (re)inventing the future of computing with light! We are hiring a Photonics Technical Lead to join our laser development team. In this role, you will develop integrated and highly scalable laser solutions for silicon photonics AI communications and computation. You will work closely with cross-disciplinary engineering teams both internally and across our ecosystem of manufacturing partners to assess the technical feasibility of product requirements, develop an engineering plan to meet architectural specifications, execute new product designs for laser solutions, and validate system performance on hardware. This role requires a deep understanding of complex multi-domain platforms as well as integrated silicon photonics and the requirements of datacom systems. You will navigate the design space of performance, schedule, reliability, power consumption, and cost, working in tandem with stakeholders across the company to identify optimal and innovative engineering solutions. Creativity, analytical skills, and clear communication skills are a necessity. Join a tight-knit team where each individual's contributions directly influence the success of the company and product. You'll have the opportunity to build innovative laser solutions from the ground up and tackle groundbreaking challenges. Work with people who love to build and who thrive in diverse technical environments where great ideas are prioritized.
