AI and Agentic Technical Lead

AI and Agentic Technical Lead | Enterprise AI

Location: UK remote, with occasional travel to London HQ
Engagement: Permanent
Package: Up to £120,000 base + bonus
Sponsorship: Unable to provide sponsorship for this position.

A rare seat for an AI practitioner who would rather set the technical bar than write the code. After a period of proving where AI can move the needle, a global enterprise now needs someone to make sure the build is sound, the vendors are honest, and the value actually lands.

About the opportunity

A large, well-established organisation with a global footprint across many industries. It recently established a dedicated AI function to find and scale the opportunities that matter most, and it is now shifting from experimentation into delivery. You would join a deliberately small senior team that has both the mandate and the air cover to influence how AI gets built across the group.

What you'll be doing

• Owning the technical quality bar across a portfolio of AI and agentic initiatives, from first scoping through to live deployment.
• Holding delivery partners to account, pressure-testing their designs, their numbers and their claims so the business buys outcomes rather than slideware.
• Calling feasibility early, where data, integration and cost realities decide whether a use case is worth pursuing.
• Setting the standards and evaluation methods that keep solutions reliable, safe and fit for purpose as they scale.
• Guiding how agentic systems get built, from tool use and orchestration through to the multi-step workflows the business is starting to rely on.
• Working shoulder to shoulder with IT, Cyber and Data, and turning technical risk into plain-English calls for senior decision-makers.

What we're looking for

• Six to ten years building real AI/ML, with the scars to prove you have taken work from prototype into production inside a large organisation.
• The judgement to assess an architecture or delivery plan on its merits without building it yourself, and to weigh build, buy or partner honestly.
• Practical, hands-on exposure to LLMs such as OpenAI or Azure OpenAI, a clear view of where retrieval-based approaches tend to break, and real experience with agentic patterns. This is a young field, so we value genuine, current hands-on work over overclaiming.
• An instinct for how AI lands in a messy enterprise, across APIs, pipelines, deployment and monitoring, and data that is rarely as clean as anyone hoped.
• Enough Python to get under the bonnet and check the work, plus a grounded sense of which modelling techniques suit which problem.
• The presence to challenge a vendor and reassure a leadership team in the same afternoon, and the temperament to thrive while the brief is still taking shape.

Qualifications

• A track record of production AI/ML in a complex organisation; degree-level education or equivalent real-world experience.
• Helpful extras: cloud AI platforms such as Azure ML, AWS or GCP, exposure to AI governance or risk, and hands-on multi-agent work.

Why join?

• Real authority. You set the technical direction and flag what will not work, rather than waiting for permission.
• Proximity to the decisions. A small team, senior sponsorship, and a direct line into where the calls get made.
• Frontier work. GenAI and agentic systems at enterprise scale, with the chance to write the playbook others follow.
• Remote-first in the UK, backed by the reach and stability of a global business.
