Mast is on a mission to make complex lending simple.
The UK's specialist lending market is underserved by technology, with legacy systems that can't handle the nuance of complex income, niche products, or the broker workflows that specialist lenders rely on.
We're building modern, cloud-native lending technology, purpose-built for specialist lenders, that helps them process more applications in less time, reach decisions faster, and deliver better experiences for brokers and borrowers.
We're pioneering the use of AI in mortgage origination, building it into the platform from the ground up rather than bolting it onto legacy architecture..
We work with regulated lenders across the UK, have a 100% delivery track record, and are building a high-performance team where everyone has real ownership and direct impact.
Responsibilities
You'll work closely with team to support the engineering effort on the Mast mortgage origination platform.
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’re looking for someone who thrives under pressure, moves fast, and delivers with urgency.
We rely heavily on Rails, Vue3 for more complex front-end pieces, Heroku for our infrastructure, and AWS.
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!
