Rethinking the limits of AI, Lightmatter merges photonics and computing to build a future where speed, efficiency, and intelligence converge. Backed by GV.
About the role
We are hiring a senior engineer for our Photonics Characterization team at Lightmatter. Lightmatter is redefining computing by building photonic systems that use light to enable high-bandwidth, energy-efficient AI computing.
What they're looking for
- PhD or Master’s degree in Electrical Engineering, Physics, Applied Physics, Photonics, Optics, or a related technical field
- 5+ years of hands-on experience in semiconductor laser, SOA, photonics, or optical device characterization
- Strong understanding of semiconductor laser physics, optical gain, carrier dynamics, rate equations, thermal effects, feedback sensitivity, linewidth, RIN, and optical noise mechanisms
- Deep hands-on experience with optical and electro-optical lab measurements
- Strong understanding of semiconductor optical amplifiers, including gain, saturation behavior, ASE, noise, carrier dynamics, polarization dependence, wavelength dependence, and thermal effects
- Strong Python programming experience for instrument automation, data analysis, plotting, statistical analysis, and automated reporting
More about this 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.
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!
