Ameba | Full-stack Engineer | London | ONSITE | £100-130k + Equity

Join us in building Ameba, an AI platform that turns supply chain noise into knowledge.

If you've never considered working in supply chains before, everything around you, including the device you're reading this on, has a story of how it got there. From raw materials to the final product in your hands, that story is its supply chain.

If you're the kind of engineer who thrives on solving novel challenges, such as building modern data pipelines to construct a supply chain from unstructured communication streams, Ameba offers you the opportunity to build from first principles in a greenfield space.

We're a seed startup made up of experienced entrepreneurs (who have previously raised $160m+, built supply chains for 30+ brands) and builders (formerly at Meta, Microsoft, Snap, Apple & Palantir). We have big ambitions and are backed by the best investors in Europe, having raised over $9m since our launch just over a year ago — and we're just getting started.

If you're interested, please email me directly via Email is hidden with [HN] in the subject. Note we are currently unable to sponsor visas.
