Senior Firmware Engineer

Cell therapies are changing how we treat some of the most devastating diseases, by using a patient’s own cells as the treatment. To bring these therapies to many more people, manufacturing must change too, becoming far more scalable, reliable and efficient. At Cellular Origins you’ll help build the firmware that drives our robotic manufacturing technology, so more patients can access life-changing treatments sooner.

As a Senior Firmware Engineer, you’ll sit at the intersection of software, electronics and automation. You’ll take technical ownership of turning motion, sensing and control ideas into reliable, production-ready firmware that keeps our systems running smoothly in a bioprocess environment. You’ll regularly see your code make motors move, sensors respond and complex systems run reliably.

You’ll join a multidisciplinary team of engineers and scientists working on our core automation platform, from first prototypes through to production systems. You’ll design, implement and test firmware that runs on ARM microcontrollers, work directly with hardware on the bench, and help shape technical decisions across firmware, electronics and the wider system.

This is not a role confined to the firmware team: you may spend as much time working with electronics, mechanical, automation and systems engineers, and with biologists, as you do with other firmware or software engineers. You’ll need to enjoy crossing disciplinary boundaries and learning enough about the wider system to help make it work as one coherent whole.

In this role, you’ll:

Own firmware development for key parts of our core technology, from requirements and architecture through implementation, verification and support in production.

Write and review high-quality C for ARM microcontrollers (primarily STM32), focusing on robust, maintainable and testable code.

Design and maintain automated tests for embedded firmware, including unit, integration and hardware-in-the-loop, and integrate them into continuous integration workflows.

Turn system needs into clear firmware requirements and interfaces, working directly with electronics, mechanical, automation and software engineers, plus biologists.
