Analytics Engineer

About the Company

My Company is based in London and appears to operate at the intersection of data and artificial intelligence, likely serving organisations that rely on sophisticated analytics and machine learning to drive decisions. The team works with modern cloud and ML infrastructure, suggesting a technically mature environment where data products are built and scaled with care. This is likely a role within a dedicated AI function, indicating that machine learning and data engineering are central to the business rather than peripheral initiatives.

About the Role

This is a senior individual contributor role sitting within the AI department, responsible for shaping how analytical and machine learning systems are built, optimised, and maintained at scale. You will work across the full lifecycle — from refining model performance and hardening LLM pipelines to establishing MLOps practices on Databricks and AWS. The position carries real architectural influence, with the opportunity to set standards that the wider team builds on.

Responsibilities

• Design, build, and maintain robust data and ML pipelines on Databricks, ensuring reliability, observability, and scalability across production workflows.
• Lead model optimisation efforts — identifying performance bottlenecks, tuning hyperparameters, and improving inference efficiency across both classical and large language models.
• Implement LLM hardening practices including prompt engineering guardrails, output validation, safety layers, and evaluation frameworks to ensure production-grade reliability.
• Own and evolve the MLOps practice: manage experiment tracking, model versioning, and deployment workflows using ML Flow and associated tooling.
• Architect and maintain cloud infrastructure on AWS to support data ingestion, model serving, and pipeline orchestration.
• Partner with data scientists, ML engineers, and product stakeholders to translate analytical requirements into scalable, production-ready solutions.
• Define and enforce engineering standards, documentation, and best practices across the AI team to raise the quality bar for all data and model assets.
