Remote Senior Machine Learning Engineer in Scunthorpe

Salary: £70,000 - 70,000 per year

Requirements

• Strong software engineering skills in Python, with experience building production‑grade data pipelines and ML DevOps.
• Practical experience with prompt engineering, designing, testing, and refining prompts for reliable LLM/VLM outputs.
• Experience with ML data workflows, including large‑scale data processing and loading, data versioning, and training format considerations such as tokenization, batching, and sharding.
• Hands‑on experience working with data pipelines for large‑scale distributed ML training runs.
• Familiarity with annotation tooling and human‑in‑the‑loop data collection.
• Understanding of ML training requirements and what good data looks like for LLM/VLM fine‑tuning.
• Experience loading and writing large datasets to and from cloud infrastructure and distributed storage systems.
• Strong communication skills to scope ambiguous problems and translate needs into actionable plans.
• A collaborative approach, with comfort taking ownership and iterating quickly.
• Experience with preference data collection for RLHF or reward modelling.
• Familiarity with multimodal data such as image‑text pairs, video, and design assets.
• Experience building synthetic data generation pipelines using LLMs.
• Background in data quality metrics and monitoring systems.
• Contributions to dataset releases or benchmarks in the ML community.

Responsibilities

• Design and build data pipelines for agent training, including collection, filtering, deduplication, formatting, and versioning across text, image, and multimodal sources.
• Build and maintain infrastructure for efficient data loading, storage, and retrieval at scale.
• Collaborate with research scientists to translate research requirements into concrete data specifications and iterate as experiments reveal new needs.
• Create evaluation datasets and benchmarks in collaboration with researchers, curating task distributions that surface real failure modes.
• Develop tooling for dataset construction, including human annotation workflows, synthetic data generation, and preference data collection for RLHF/DPO‑style training.
• Own data quality by building validation frameworks, monitoring for drift and contamination, and establishing standards for trustworthy and reproducible datasets.
• Document datasets thoroughly, including provenance, known limitations, intended use cases, and versioning history.
• Implement comprehensive test coverage for data pipelines and ML workflows to ensure reliability and catch regressions early.
• Elevate codebase quality through code reviews, refactoring, and establishing engineering best practices that help research velocity scale sustainably.
• Contribute to team roadmaps by identifying data bottlenecks and proposing solutions that unblock research velocity.
