At Encord, we're building the AI infrastructure of the future. The biggest challenge AI companies face today isn’t model design — it’s data quality. The performance of any AI system ultimately depends on the quality of its training data, and for most teams, this remains the most costly and time‑moving part of getting products to market.

As former computer scientists, physicists, and quants, we experienced first‑hand how the lack of modern tools for producing high‑quality training data slowed progress. AI today feels a lot like the early days of computing or the internet — enormous potential, outdated tooling. That’s why we founded Encord.

We’re now a team of 100+, working at the frontier of computer vision and deep learning. Backed by top‑tier investors including CRV, Y Combinator, and industry leaders like Luc Vincent (former VP of AI at Meta), we’re one of the fastest‑growing companies in our space and consistently ranked the #1 platform in the market by our customers.

We’re now looking for a driven Account Manager to join our London GTM team and help expand our footprint within some of the most advanced AI organisations in the world.

As an Account Manager (Expansion) at Encord, you’ll own and grow a portfolio of strategic UK and European customers. Your focus will be on expanding usage, driving adoption, and ensuring customers get maximum value from our platform — from autonomous vehicle companies to medical imaging teams and next‑gen robotics groups.

You’ll work directly with technical and commercial stakeholders, understand their ML workflows, and identify opportunities for growth. This is a great fit for someone who loves building long‑term relationships, enjoys technical conversations, and wants to help shape the future of AI infrastructure.

• Strong relationship builder with a genuine interest in solving customer problems
