Staff Photonics Design Engineer
About the role
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. In this role, you will design, layout, and test silicon photonics devices for an integrated and scalable laser system. You will collaborate closely with cross-functional teams including photonics, packaging, systems, and software to define and refine specifications, ensuring that all designs meet or exceed performance targets and align with product requirements.
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.
Responsibilities
- Design and optimize silicon photonic devices for laser systems, including couplers, muxes, rings, switches, and other active and passive components.
- Layout device test structures as well as complex integrated photonic systems.
- Work with the characterization team to develop and execute test plans for device validation, analyzing results to assess performance and troubleshoot issues.
- Work closely with packaging and systems engineering teams to address integration challenges, ensuring high alignment between device and system requirements.
- Implement rigorous simulation, modeling, and testing methodologies to calibrate designs and optimize performance across manufacturing variability.
- Engage in problem solving and contribute to new device designs and architectures.
- Publish novel photonics results, and participate in premier optics/photonics conferences.
Requirements
- PhD in Electrical Engineering, Physics, Photonics, or related discipline with 3 years of industry experience.
- Experience in silicon photonics device design, layout, and testing, ideally in a product development environment.
- Demonstrated track record of designing integrated silicon photonics components using Lumerical, Tidy3D, or equivalent.
- Proficiency in modeling and data analysis in Python.
- Experience with integrated lasers, SOAs.
- Excellent communication skills, with a demonstrated ability to collaborate effectively with multidisciplinary teams.
- Strong problem-solving skills in problems that do not have obvious solutions.
- Can-do, positive attitude.
Preferred Qualifications
- Experience doing layout with foundry PDKs.
- Experience with code-based GDS creation such as GDS Factory or similar.
- Experience with optical and electronic test equipment, wafer-level testing and statistical data analysis (e.g., optical spectrum analyzers, tunable lasers, OBR/OVA, oscilloscopes, BERT).
- Strong project execution skills, with the ability to handle multiple priorities and meet project milestones.
