ABOUT THE ROLE

Banks and fintechs use Taktile to automate critical decisions - like credit and risk - in real time. We're a startup in the automated decisioning space - and the backend is where the hard problems live.

We're looking for a Senior Backend Engineer to join our engineering team. In Team Decide you'll focus on designing the distributed execution engine that runs customer workflows. You'll own critical systems end-to-end on a small team where your decisions shape the product.

- Work directly with Product and Design to shape what we build next.

- Strong communication and collaboration skills, with the ability to align technical and non-technical stakeholders on a shared vision.

- The ability to work in a hybrid model from our Berlin HQ, the Lon...
