Job Description & How to Apply Below
Our autonomous vessels spend months alone ry decision they make — from navigating changing sea states to collecting sensor data, communicating with shore, and managing power — depends on reliable embedded software.
As we scale both our platform and our fleet, we are looking for a Firmware Engineer to help evolve the embedded systems that make this possible. You will work closely with our CTO, electronics, robotics, and software teams to develop firmware that is robust, maintainable, and ready for the next generation of C-Star deployments.
What You'll Do- Become a key technical owner of the firmware systems that power the C-Star platform
- Design and delivery of production-grade embedded software for deployed autonomous systems
- Contribute to the evolution of the firmware architecture as the platform and fleet continue to scale
- Firmware reliability, performance, power management, fleet update capability, and maintainability across deployed vessels
- Development of testing, CI/CD, containerised builds, code review, documentation, and collaborative development workflows
- Close collaboration with electronics, hardware, cloud, autonomy, and product teams to bridge firmware with the wider technology stack
- Debugging hardware/software interactions in the lab, on the bench, and in real deployment contexts
- Mentoring junior engineers as the firmware team grows and helping shape the long-term firmware roadmap
- Strong embedded C/C++ firmware development experience on shipped, production products
- Experience developing firmware for resource-constrained embedded systems
- Experience with STM
32 or comparable ARM Cortex-M microcontrollers - RTOS experience, ideally FreeRTOS, including task management, queues, semaphores, and inter-task communication
- Strong software architecture and system design skills
- Comfortable working at the hardware/software boundary — reading schematics, debugging on the bench, SPI/I2C/UART protocols
- Experience with collaborative engineering:
Git workflows, code review, documentation - Ability to work independently in an ambiguous environment and make sound engineering decisions
- Robotics, drones, aerospace, marine, defence, automotive, or IoT experience
- Autonomous systems, sensor fusion, GPS, IMU, acoustic, or environmental sensor experience
- Satellite communications:
Iridium, Rock Block, LoRa, cellular, VHF - Low-power firmware design, duty cycling, resource-constrained embedded systems
- Signal processing, acoustic analysis, edge compute, or embedded AI/ML experience
- PCB design, electronics co-design, or deeper hardware development experience
