Embedded Software Engineer (Lasers)

Join Lightmatter, a pioneering company in extreme-scale artificial intelligence computing clusters. As an Embedded Software Engineer, you will work on the control plane and diagnostics software for next-generation photonic interconnect products. You will collaborate with a multidisciplinary team and have a visible impact on 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.
• Integrate transceiver management and telemetry with data center administration interfaces such as CMIS, OpenBMC, and DMTF standards.

• Solid understanding of hardware-software integration, including common embedded peripherals and buses (I2C, SPI, UART, GPIO)
• Working knowledge of Git, and experience with CMake or a comparable build system
• Degree in Computer Science, Electrical Engineering, Robotics, or a related technical field
• Experience developing firmware in resource constrained environments; experience in both bare-metal and RTOS systems preferred. FreeRTOS, Zephyr or other modern RTOS experience preferred
• Experience contributing embedded software to a product that shipped to customers, or to hardware that reached production or field deployment
• Proficiency in C or C++, and comfort with Python for tooling, test, and analysis
• Hands-on lab experience debugging embedded systems with GDB, JTAG, logic analyzers, or oscilloscopes
• BS and 5+ years of experience, MS and 3+ years of experience, or a PhD; equivalent practical experience also considered
• Demonstrated ability to take ownership of a defined problem, work through ambiguity, and deliver on commitments in a fast-moving environment
• Coursework, research, or industry experience in closed-loop control: designing, simulating, or deploying control algorithms on real systems
• Experience developing firmware for optical transceivers, photonic systems, or other precision analog/mixed-signal hardware
• Familiarity with CMIS, OpenBMC, DMTF/Redfish, or similar platform management environments
• Exposure to optical communication systems, laser physics, or thermal and wavelength stabilization techniques
• Familiarity with optical test and measurement, and with methodologies for characterizing optical components and systems
• Experience building test automation, hardware-in-the-loop test benches, or CI for firmware
• A track record of learning unfamiliar technical domains quickly and becoming the person teammates come to with questions
