- Implement device communication and error handling in collaboration with hardware and firmware teams.
- Develop reliable service behavior, including startup, shutdown, reconnection, logging, and recovery from faults.
- Collaborate with React developers to align API behavior, system state, and user workflows.
- Ability to expand beyond your comfort zone in the stack - this means helping where needed.
- Improve CI/CD pipelines and development tools.
- Maintain clear documentation for APIs, services, communication interfaces, and debugging procedures.
