Responsibilities
- Design and build C++ firmware for distributed aircraft microcontrollers.
- Develop reliable Ethernet, serial, and other microcontroller communication interfaces.
- Define platform-level interfaces and reusable firmware components for multiple aircraft subsystems.
- Own microcontroller performance and communication-bus reliability across startup, real-time operation, fault handling, and recovery.
- Optimize CPU utilization, memory usage, scheduling latency, timing jitter, and resource contention.
- Develop metrics, monitoring, and troubleshooting capabilities for field deployment at scale.
- Develop Rust-based tooling and software-in-the-loop simulations to test and validate firmware behavior.
Requirements
- Production experience writing C++ for embedded or resource-constrained systems.
- Experience with embedded communications such as Ethernet, serial interfaces, or other hardware communication protocols.
- Experience designing and debugging real-time firmware involving task scheduling, interrupts, concurrency, synchronization, and memory constraints.
- Experience building and maintaining deployed embedded systems and handling edge cases for safety, reliability, and performance.
- Strong systems debugging skills and the ability to narrow down potential causes of failures.
- Fluency implementing peripheral drivers from electrical schematics and datasheets and debugging at the hardware-software boundary.
- Ability to work from the South San Francisco office on a regular basis in a hybrid work environment.
Benefits
- Hybrid in-office and distributed work environment centered around the South San Francisco, California headquarters.
- Equal opportunity employer committed to diversity and nondiscrimination.
