Principal software engineer: Compiler and Tools at XMOS
Bristol, GB

The role is based in Bristol, UK.

You’ll work within the Software Group and interact with the applications team and developers – the ‘leading edge’ consumers of the tools that you will develop. Your main responsibilities will include:

  • Developing and maintaining the XMOS C, C++ and XC compilers;
  • Designing and implementing optimizations to address performance, code size, power consumption and timing closure for real-time programs;
  • Static and dynamic code analysis for measuring timing and detecting deadlock;
  • Generating DWARF debugging information for optimized code;
  • Actively contributing to and sharing LLVM compiler improvements with the open-source community;
  • Working with the apps team and with customers to contribute to development of the XC concurrent and real-time programming language;
  • Working with the silicon team to contribute to development of next-generation XMOS products and architecture; and

As a member of a software engineering group, your responsibilities will also include:

  • Collaboration with agile planning processes;
  • Software design, implementation and documentation;
  • Automated test implementation;
  • Code reviews and support for other development on going within the team;
  • Collaboration with engineers from a range of disciplines to deliver complete, production ready systems.

You’ll need to be self-directed, proactive and equally comfortable working as part of a team or independently and you’ll enjoy solving day-to-day problems with limited direction.
