Our custom chips, accelerators, and software stacks enable us to take on technical challenges that have never been seen before, and deliver results that help our customers change the world. We are seeking a Senior Firmware Engineer to join our Power Architecture team, developing firmware algorithms for power and performance management on ML Acceleration Chips. In this role, you will design and implement intelligent control algorithms, optimization strategies, and real-time decision-making systems that maximize performance while managing power and thermal constraints. You will develop sophisticated firmware that monitors system state, makes dynamic trade-offs between power and performance, and implements adaptive control policies. To enable this work, you will also build instrumentation and tracing capabilities that provide the telemetry needed to develop, tune, and validate your algorithms, with collected data optionally post-processed using cloud-based analytics. Key job responsibilities

• Design and implement firmware algorithms for power management, thermal control, and performance optimization on ML acceleration hardware
• Develop real-time control policies and state machines that dynamically balance power, thermal, and performance constraints
• Create optimization algorithms for resource allocation, frequency/voltage scaling, and workload scheduling
• Implement efficient data structures and algorithms suitable for embedded, resource-constrained environments
• Design and implement on-device tracing and telemetry collection systems to support algorithm development and validation
• Build developer tools and data pipelines for metric collection, analysis, and visualization of algorithm behavior
• Implement low-overhead instrumentation that minimizes impact on workload performance
• Collaborate with hardware architects to understand hardware capabilities and identify optimal instrumentation points
• Develop automated testing and validation workflows; integrate with optional cloud-based analytics pipelines
• Own firmware code quality through rigorous testing, debugging, and validation on hardware

A day in the life You will work closely with power architects and hardware teams to understand silicon capabilities, implement low-level control mechanisms, and create the algorithms and tooling that deliver optimal system behavior. This position is ideal for firmware engineers who enjoy solving algorithmic challenges in resource-constrained environments, working close to hardware, and building systems that intelligently manage complex trade‑offs in real‑time.
