Do you want to utilise your skills to help cure cancer and heart failure, and make a real-world impact?

AI Science and Autonomous Labs are buzzwords; we’re building the actual robotics and software tooling to enable scientists to design, execute and analyze experiments without human intervention.

This includes complex electromechanical instruments that combine robotics, fluidics, sensors, and software. The electronics and firmware are what make these systems work.

We need an embedded systems engineer who can own both: the boards and the code that runs on them.

This is a role for someone who genuinely works across the full stack of embedded development; schematic capture and PCB layout one week, production firmware in C/C++ the next, field debugging a deployed system the week after. You'll take a design from concept through to manufactured, tested hardware running production firmware in a real lab.

If you've spent your career at a consultancy handing off designs you never see shipped, or at a large company owning one narrow slice of a system, this is your chance to own the whole thing.

• Engineers who care about what they build, not just how.
• Clear thinking, pragmatism, and sound judgment over buzzwords.
• A bias for action to build products with customer value.
• Friendly, organised, efficient, and enthusiastic people with a can-do attitude.
• People who take responsibility and follow problems through.
• Using the right tools, including AI, to work smarter, not harder.
• Low-ego individuals who love asking questions & go above and beyond to help the team succeed.

You’ll work alongside our principal engineer to own the electronics and embedded systems across our products and platforms. Day-to-day, that means:

• Schematic design and PCB layout for control boards, sensor interfaces, power distribution, and system interconnects.
• Writing and maintaining production firmware in C/C++ on STM
  32/ARM microcontrollers, real-time control of pumps, valves, sensors, and actuators.
• Designing and implementing inter-device communication (CAN, Ethernet, serial) across networked instruments.
• Building the integration layer between embedded systems and our monitoring platform and telemetry stack; APIs, data pipelines, and control interfaces.
• Prototyping and validating designs in our in-house electronics workshop, driving rapid iteration from concept to working board.
• Design for manufacture: translating prototypes into production-ready boards, managing BOM optimisation, and coordinating with contract manufacturers.
• Supporting EMC, CE, and UL compliance testing and designing for long-term reliability in regulated environments.
• Field debugging and supporting deployed systems, diagnosing issues remotely and on-site, and feeding lessons back into the codebase.
• Contributing to system architecture decisions as we scale from single instruments to multi-unit autonomous production lines.

You’ll have high autonomy and direct influence on technical decisions. The learning curve is steep, but you’ll expand your skills faster here than in most environments, and everything you build ships to real customers.

• Demonstrated experience across both electronics hardware design (schematic capture, PCB layout, component selection) and firmware development (C/C++ on microcontrollers such as STM
  32/ARM).
• Competence with PCB design tools (Altium, KiCad, or equivalent), hands‑on prototyping skills: comfortable with soldering (THT and SMD), rework, and bench testing.
• Strong understanding of real-time systems, interrupts, peripherals, and hardware abstraction layers.
• Experience with communication protocols: CAN, SPI, I2C, UART, Ethernet/TCP‑IP.
• Comfort interfacing embedded systems with higher‑level application layers (Python, REST APIs, MQTT, or similar).
• Evidence of taking designs from concept through to production hardware running deployed firmware.
• Experience developing or maintaining full‑stack software with a Python backend.
• A methodical approach to debugging, testing, and documentation.

• Exposure to industrial…
