Runtime Engineer

Codeplay - full time - £27,000 to £53,000

Edinburgh, UK

29 Jun 2017


Runtimes are key components to enable higher-level programming models such as SYCL to efficiently target various modern heterogeneous hardware platforms.

Your primary responsibilities will be to implement and improve runtime systems to target brand-new hardware such as GPUs, mobile CPUs and DSPs. Writing, testing, debugging and maintaining code, whilst interacting closely with other team members and clients, is a central part of the job.

Runtimes are usually implemented close-to-the-metal and interact directly with hardware and/or drivers as well as compilers. Actual driver work may also be involved. Each platform has its own eccentricities, and successful candidates will be able to investigate and implement solutions by working around quirks or exploiting them for performance, power or memory gains.

The Environment
Codeplay has a relaxed working environment and you will be working alongside other creative and talented developers. Codeplay is regarded as being at the forefront of compiler and development technology and has active participation in several research programs within the European union, the Khronos Group and the HSA Foundation

The ideal candidate is a self-motivated individual who can work through a problem from start to finish, to deadlines as required to support software projects, and sometimes under pressure. They will be working on technology that is usually not publicly announced and may be several years away from public release, and candidates must understand the secretive nature of the work that we undertake.

The position is permanent and will be based at our head office in central Edinburgh. Salary Range (dependent on experience) £27,000 to £53,000.

What We Offer
Codeplay is internationally recognized as being at the forefront of software development technology, and working with us offers unique opportunities and challenges to learn new technologies and to be involved in shaping the software industry. Codeplay's projects range from: creating tools and tool sets (optimizing compilers, debuggers, profilers, programming models & APIs, test systems/suites, ...) for brand-new unannounced next-generation hardware; developing and optimizing current machine learning (TensorFlow) and computer vision applications; research and development into lowering the power consumption of mobile devices, and contributing to new programming models and software standards (e.g. C++, SYCL™, OpenCL™, Vulkan® and SPIR™-V).

Codeplay is an active contributor in the community for the Clang, LLVM and LLDB open-source compiler and debugger projects. Our engineers are also leading the effort to bring support for machine learning with TensorFlow to OpenCL-enabled devices, by adding support for the SYCL for OpenCL open standard to the open-source codebase. We are building an ecosystem around SYCL (the C++ high-level , including public projects for computer vision, linear algebra, and C++ parallel programming APIs - see If you are excited about contributing to programming tools that will be used by developers worldwide, please get in touch!
