AI/ML Engineer

Salary: £43,000 - 83,000 per year

Requirements:

• Degree in Computer Science, Artificial Intelligence, Machine Learning, Software Engineering, Data Science, or a related technical discipline, or equivalent hands-on experience; an MSc or PhD is welcome but not essential.
• Exceptionally strong Python programming skills, including object-oriented design, clean code, and software engineering principles such as SOLID, design patterns, modularity, and testability.
• Strong backend and API engineering experience, ideally with Python frameworks such as FastAPI or similar.
• Hands-on experience building and operating solutions in AWS environments.
• Proficiency with Docker, GitHub, and CI/CD pipelines.
• Proven ability to work across teams and drive delivery into production.
• Strong problem-solving, debugging, and performance optimisation skills.
• Solid software engineering foundations, including version control, automated testing, and monitoring.
• Desirable: Experience building or productionising agentic AI systems, including tool use, orchestration, multi-step reasoning, or agent frameworks such as LangGraph, LangChain, CrewAI, AutoGen, or similar.
• Desirable: Experience with production GenAI or LLM systems, including RAG, prompt orchestration, evaluation, guardrails, and cost or latency optimisation.
• Desirable: Exposure to MCP (Model Context Protocol) and tool-based or function-calling architectures.
• Desirable: Experience deploying and operating machine learning models or MLOps pipelines, such as model serving, monitoring, and retraining workflows.
• Desirable: Experience with real-time or streaming systems.

Responsibilities:

• Design and build robust, secure APIs and backend components that power AI/ML, GenAI, and agentic applications.
• Engineer agentic systems by integrating LLMs with tools, data sources, and business workflows into reliable, production-grade pipelines.
• Take systems from prototype to production, owning reliability, scalability, and operational readiness.
• Improve code quality, structure, and production readiness across the AI/ML stack.
• Debug and resolve issues across APIs, environments, and integrations to support rapid response and minimise disruption.
• Partner with Data Science, Engineering, DevOps, and Infrastructure teams to take solutions from development through live deployment.
• Advise and support colleagues across the business whose systems integrate with AI/ML and agentic components.
• Resolve technical ambiguity proactively to reduce delivery friction and rework and ensure smooth handovers from prototype to production.
• Establish and evolve engineering standards for productionising AI/ML, including testing, observability, versioning, and release management.
• Mentor and guide data scientists and engineers through code reviews and hands-on technical support.
• Promote disciplined engineering, continuous improvement, and operational excellence within our Data Science team.
