Project lead firmware development for multidisciplinary scientific manufacturing applications

Cambridge South;-to -85,000 DoE + Benefits

This growing engineering product start-up has taken their innovative technology to market and has already established partnerships with multiple stakeholders within robotic scientific manufacturing systems. They are looking to hire a senior / principal level Firmware Engineer to join their multidisciplinary team.

As a senior engineer, you would take technical ownership of firmware development for sensors, controls, motors and electromechanical components. Your code will keep systems running smoothly and you will champion code quality, reliability and delivery. Further, you will be a key individual within the team, collaborating with electronics and mechanical engineers as well as scientists.

Requirements:
- An extensive track record designing and building embedded systems, with a strong appreciation of applied hardware (including motors and sensors). This should include firmware used in prototyping to production ready delivery.
- Extensive demonstrable experience with C and C++ firmware development for ARM microcontrollers (ideally STM32). Additional experience with C# or Python would be desirable.
- Strong project development process experience including relevant automated tests for embedded systems, debugging complex hardware systems and even understanding of electronics schematics.

Projects are complex and sophisticated, so an ethos of teamwork and collaboration is fostered. This means that strong communication skills are expected. Further, technical management and architecting experience would be needed.

Due to the nature of projects, this role is based fully onsite at their offices and workshops. Parking is available on premises. On offer is an excellent remunerations package including a wide range of benefits. Interested candidates are expected to be based close to offices, located in the south of Cambridgeshire (commutable from Cambridgeshire, north Essex, north Hertfordshire and west Bedfordshire).
