Senior Software Engineer

A well-funded AI engineering organisation is hiring a Senior Software Engineer to deploy, extend, and optimise a leading open-source LLM inference engine, across two core programmes: a scaling inference initiative and a high-assurance/regulated-environment initiative.
What you'll do
Deploy, instrument, and monitor open-weight models served via the inference engine
Build new engine features to support novel hardware architectures
Extend the engine for accuracy, explainability, and accountability in regulated settings
Contribute upstream to the relevant open-source community
Optimise inference performance (latency, throughput, hardware utilisation)
What they're looking for
Senior-level Python + low-level programming (C/C++, Rust, CUDA)
Direct contributions to a major inference/serving engine or similar ML infra project (e.g. PyTorch, Ray)
Strong grasp of LLM inference internals (KV caching, batching, quantisation)
Experience up streaming to active OSS communities
Hardware accelerator optimisation experience (GPU/TPU/etc.)
Genuine enthusiasm for AI-assisted development (LLMs/agents as core tools)
Nice to have: regulated-environment experience, AI safety involvement, MLOps/CI/CD depth.
