Software Engineer - Full Stack

Remote - UK Full Time Mid Level
£50K - £60K Yearly

Published on April 25, 2024

Founded in 2020, our mission is to empower mortgage lenders and leverage technology to enable them to focus on what they do best, lending. An oligopoly of technology suppliers provide a handful of systems that are outdated, get infrequent updates and are painful to customise. Lenders are frustrated and ready for change.
Mast is building cloud-native mortgage technology to help lenders process more mortgage applications in less time. We want to help lenders get to a mortgage decision a lot faster and a lot more efficiently, transforming the buying journey for the borrower.
We are building self-service products where lenders own all the controls and levers so that they can offer the best service possible. We strongly believe that solving and addressing the hard problems at the roots is the only way to transform an industry.

Mast is solving one of the most important problems in lending: Speed. Our mission is to make lending better, smoother and faster for everyone. We do that by empowering mortgage lenders and leveraging technology to enable them to focus on what they do best – lending.

You'll work closely with team to support the engineering effort on the Mast platform, our state-of-the-art mortgage origination system. That means helping to scope user stories, participating in sprint planning, and writing, testing and deploying great code. We're very much inspired by the Pivotal Way.
We're growing the team to be able to ship more features and onboard more clients. But we're still a small team, so everyone's expected to pitch in to all parts of the product and engineering lifecycle!
We rely heavily on Rails and friends (Turbo + Stimulus), Vue for more complex front-end pieces, Heroku for our infrastructure, and AWS for backing services. 
Our interview process is an initial phone screen, a take-home code task, and a half-day on-site (or remote) pairing session. We promise not to ask you any trick questions or make you code on a whiteboard!

  • Experience writing automated unit, integration and end-to-end tests in RSpec
  • Working knowledge of Unix-like operating systems
