Software Engineer

Description

SAPI’s mission is to build the lending infrastructure for the web. We are a FinTech that enables payment companies to offer their sellers fast and fair business financing and earn a revenue share. We are well-funded and backed by several famous angels, unicorn founder-turn-investors and many of the UK and Europe’s top venture funds.

Our 3 founders are technical experts with >10 years each in Credit, Tech and Data; ex Goldman Sachs, Iwoca, and Morgan Stanley. We are looking for founding engineers who will work directly with our CTO, Senior Product Managers, and external stakeholders. You are the foundation of our engineering team from a technical and cultural standpoint. You set the bar in terms of execution pace, quality, and how we select candidates after you. While you will need to be comfortable with the lack of structure and possibly wearing multiple hats, building our business directly with 3 founders means making complex technical/architectural decisions and developing and leading a team around you.

We are highly invested in you. Besides attractive compensation, our priority is that the work and opinions of our founding engineer will be treated with equal importance as the founders themselves.
