The Role

As our Research Engineer, you will sit at the boundary between frontier machine‑learning research and shipped product.

You will take ideas from the research edge, reinforcement learning, RLHF, multi‑objective policy optimisation and LLM post‑training, and turn them into capabilities that make our platforms measurably better.

This is a Research Engineer role.

You will read the literature, prototype quickly, and see your work through into systems our customers depend on, while connecting that research to OD’s product vision and to what our customers actually need.

Responsibilities

• Apply and adapt machine‑learning and reinforcement‑learning research to OD’s product roadmap, translating research direction into shippable capability.
• Design, train and evaluate models using reinforcement learning, RLHF and multi‑objective policy optimisation, balancing competing objectives such as accuracy, safety, latency and cost.
• Work on LLM post‑training: fine‑tuning, alignment, reward modelling and rigorous evaluation.
• Prototype fast, then work with the engineering teams to harden what works into production.
• Define how frontier models can be evaluated and how decision making can be audited.
• Engage directly with customers and stakeholders, explaining technical approaches to non‑specialists and feeding real‑world needs back into the research agenda.
• Help shape OD’s research and product vision, bringing a clear point of view on where the field is heading and what OD should build next.

Requirements

• Ph D in AI, machine learning or a closely related field, or holding a current postdoctoral research position in Machine Learning.
• Strong grounding in Machine Learning and reinforcement learning, including RLHF.
• Hands‑on experience with multi‑objective policy optimisation.
• Solid knowledge of transformer architectures and LLM post‑training (fine‑tuning, alignment, reward modelling).
• Publications at top‑tier AI conferences such as ICML, ICLR, Neur IPS, CVPR, etc.
• Experience using HPCs and CUDA for training large‑scale models.
• The ability to translate research into a product vision and carry it through to delivery.
• Nice to have
• Computer vision experience.
• Open‑source contributions.
• Applied research that shipped into a product.
• Soft skills

Commercial thinking

an instinct for connecting research effort to product value and customer impact, rather than research for its own sake.

Communication and client‑facing skills

able to explain complex ideas clearly to both technical and non‑technical audiences, including customers.

Calm, judgement‑led decision making

and comfort operating in ambiguity with fast‑moving priorities.
