AI / ML Engineer
Build and maintain the model pipelines behind our product — fine-tuning, retrieval, evaluation and the harness that decides what ships.

About the Role
Our model layer is the product, not a feature of it. This role builds and maintains the pipelines behind it — fine-tuning runs, retrieval components, evaluation datasets and the scoring harness that decides whether a model version ships.
You work under the AI/ML Lead alongside our AI fellows, which means part of the job is setting the standard for how experiments are run and recorded. This is applied engineering, not research: the measure is whether it works in production for a client.
Key Responsibilities
Build model pipelines
Data preparation, fine-tuning runs, checkpoint management and deployment.
Own retrieval quality
Chunking, embedding, reranking — and measuring whether each change actually helped.
Write the evaluations
Build golden datasets and regression suites so model quality is a number, not an opinion.
Do the error analysis
When output is wrong, find out why and fix the cause rather than the prompt.
Watch cost and latency
Track inference cost per transaction and keep it inside the envelope.
Work with the fellows
Review their experiments and help them reach production standard.
What You Bring
- 3–5 years in applied machine learning, or an AI fellowship with demonstrated production contribution.
- Strong Python; PyTorch and the Hugging Face ecosystem as daily tools.
- You have run a fine-tune and can explain why it did or did not move the metric.
- Retrieval pipelines built and tuned in production — and measured, not assumed.
- You write evaluation datasets rather than judging model output by eye.
- You can read a paper and tell whether it is worth implementing.
What Would Be Great to Have
- OCR and document extraction pipelines.
- Speech and audio processing.
- Quantisation and inference optimisation.
- Model governance and documentation under ISO 42001.
