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: 6+ months • IR35 Status: Outside IR35 • Location: Remote (UK or EU preferred) • Start Date: ASAP
