Senior Data/ML Engineer – Contract Position – HIRING ASAPLocation: London Bridge – In office 2-3 days per week Start Date: ASAP Duration: 3-4 months with extension Daily Rate: £400 - £450 per day outside IR35SummaryYou will sit with the Head of Data and the Lead Data Scientist/Engineer. You will be pointed at inputs and expected outcomes, then expected to design and build the path between them - including the data model – with light review.The work still must be grounded: clear schemas, sensible storage layout, production-quality Python. It is not cowboy scripts, and it is not waiting for a backlog of tickets.This is a bad fit if you mainly plug enterprise components together, wait for JIRA epics, or treat AI coding tools as a novelty. This is a good fit if you have built data/ML systems in a startup or small product team, you use Cursor/Copilot (or equivalent) as a normal part of shipping, and you can own a problem from messy source files to a running pipeline without being sequencedRequirementsStrong production PythonEvidence of designing data models and schemas, not only consuming themComfort operating with incomplete requirements: inputs and outcomes, then you fill in the middleCan take messy inputs and an expected outcome, then design schema + build the pipeline with light reviewEvidence of designing a production pipeline from messy source data, not just orchestrator configAI-assisted development as a default way of working, not a talking pointUsing AI coding tools (Cursor, Copilot or equivalent as a normal way of shipping4+ years shipping data or applied ML systems in productionPrevious experience in a start-up or a small product teamBonus SkillsDagster, or Airflow, or Prefect in productionData lakes / Parquet / S3Terraform or general cloud familiarity (infra is owned by another team)RAG, embeddings, or other LLM-adjacent pipelinesStartup or small-team product deliveryResponsibilitiesTurn client data (APIs, CSVs, S3, messy operational exports) into reliable Python pipelines.Specify schemas and storage layout (Parquet on S3, layered / medallion-style) so the next person can extend the work.Orchestrate jobs in Python.
