Job Description: Compiler Engineer [Contractor] Company Overview designs and manufactures optical processors built to train and run inference on large-scale AI models. Contract Overview We are seeking an experienced and highly motivated Compiler Engineer (Contractor) . You'll collaborate with our in-house engineering team to deliver a production-ready ML backend —including compiler, runtime, debugger, and a functional simulator—for our next-generation Optical Tensor Processing Units (OTPUs). This role requires deep technical expertise in compiler construction, runtime systems, C/C++ programming, and ML framework internals. Key Responsibilities Compiler Development Design and build a compiler extensible to future optimisation patterns such as op fusion, layout optimisation, tiling, and scheduling. Debugger & Diagnostics Implement optional runtime assertions, compile-time dump mechanisms, TensorBoard timelines, and JAX I/O callback support. Functional Simulator Develop a simulator that mimics our kernel-space driver, enabling the software team to lower operations ahead of hardware availability. Required Skills & Experience 5 years of professional experience in C/C++ software engineering Strong background in compilers , runtime systems , and low-level optimisations Deep familiarity with ML frameworks (e.g., PyTorch, JAX, TensorFlow) and their execution models Experience with high-performance computing or hardware-software co-design Strong problem-solving skills with a creative and pragmatic mindset Comfortable operating in fast-paced , ambiguous environments Bachelor's degree (or higher) in Computer Science, Electrical Engineering, Mathematics, or a related field Excellent communication and collaboration skills Contract Details Length : 3 months IR35 Status : Outside IR35 Location : Remote (UK or EU preferred) Start Date : ASAP
