Sr. Staff Engineer, Platform Firmware
$170,000–$223,000 year
On-site · San Jose, California, United States
Job Summary
Own and evolve platform-level firmware running on STM32-based systems used for demos, validation, and customer enablement. Develop firmware that controls and monitors ADCs, DACs, regulators, laser modules, and other board-level components. Build and maintain firmware that emulates customer platforms, enabling realistic system behavior without requiring full customer SoCs. Support and scale firmware across multiple board designs, balancing reuse, configurability, and maintainability. Lead board bring-up and sign-off, working hands-on in the lab to validate functionality and readiness. Review schematics and PCB designs, providing actionable feedback to the hardware team when changes materially improve firmware robustness, testability, or system reliability. Coordinate closely with the embedded firmware team responsible for photonic IC control, ensuring clean interfaces and effective system validation. Develop board-level firmware that controls, exercises, and tests embedded firmware running inside Ayar Labs’ and customers’ SoCs. Partner with systems, validation, and customer-facing teams to debug complex cross-domain issues.
