Senior Research Engineer - Machine Learning & Generative AI
We're hiring an experienced Senior Research Engineer to join a world-leading technology organisation working at the frontier of AI and machine learning research.
This is an unusually research-heavy engineering opportunity. You'll be embedded directly within a cutting-edge AI research team, working on areas including large language models, reinforcement learning, synthetic data, multi-agent systems and AI agents, while also building the robust infrastructure needed to support complex research experiments.
- 5-7 years' relevant experience, with strong hands-on Machine Learning/AI expertise.
- Strong Python programming skills - a core non-negotiable.
- Proven experience developing machine learning models at scale, ideally within a leading technology company, AI research lab or similarly sophisticated environment.
- Experience writing production-quality software and running complex experiments involving large AI models and datasets.
- Strong scientific/research mindset - able to investigate not just whether an approach works, but why.
- Comfortable working at pace in a highly ambiguous research environment where priorities can change rapidly.
Experience with PyTorch, LLMs, LLM post-training, reinforcement learning, generative AI or multi-agent systems would be particularly valuable. A research-focused Master's or PhD in AI/ML is advantageous but not essential.
Deadline for this role is Monday the 14th of September.
