The ideal candidate will additionally have experience of a good subset of the following:

• Real-Time C/C++
• Experience of at least one higher level language for tooling or test automation (for example Python or C# & .NET).
• Broader embedded experience such as RTOS, bare-metal systems, hardware interfacing, DSP, algorithms, protocols (application layer and low level), and state machines.
• Experience of working at the boundary between electronics and software, and able to read an electronics schematic when designing and developing embedded firmware solutions.
• Ability to diagnose and resolve complex system wide software and system-level issues.
• Good communication skills, with the ability to write technical documentation for internal and client circulation.
