Embedded Software Engineer (Lasers)
Company: Lightmatter
Location: Boston, MA
Salary: $140k - $165k per year
Type: Full-time

About this role
- Lightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. Join a multidisciplinary team to pioneer the future of computing by building the world’s most advanced communications lasers
- In this role you will help build the control plane and diagnostics software behind next-generation photonic interconnect products - implementing laser control and stabilization routines, the telemetry and monitoring firmware that keeps them healthy in the field, and the tooling that brings new hardware to life
- You will work shoulder-to-shoulder with photonic, analog, digital, and systems engineers, own well-defined pieces of the stack end to end, and grow your depth in a domain where very few engineers have experience. Your work will be visible in every product we ship
- Implement and tune active laser control and stabilization algorithms on embedded targets, working from architecture and control approaches defined with the cross-functional design team
- Own delivery of well-scoped firmware components for photonic transceiver diagnostics, telemetry, and monitoring; from requirements through bring-up, test, and release
- Contribute to control plane and diagnostics architecture discussions across a multidisciplinary team of photonic, analog, digital, systems, and network engineers
- Integrate transceiver management and telemetry with data center administration interfaces such as CMIS, OpenBMC, and DMTF standards
- Bring up new hardware alongside hardware engineers, and debug embedded systems using GDB, JTAG, logic analyzers, and oscilloscopes
- Characterize and debug laser behavior using optical test and measurement equipment, and build the automated test and data collection scripts that make that work repeatable
- Adapt existing practices where they fit and devise new approaches where precedent is limited, working independently with review at critical checkpoints
- Write clear documentation and share findings with engineers outside your specialt...
