Job description

About Engine by Starling

At Engine by Starling, we are on a mission to find and work with leading banks all around the world who have the ambition to build rapid growth businesses, on our technology. Engine is Starling's software-as-a-service (SaaS) business, the technology that was built to power Starling, and two years ago we split out as a separate business. Starling has seen exceptional growth and success, and a large part of that is down to the fact that we have built our own modern technology from the ground up. This SaaS technology platform is now available to banks and financial institutions all around the world, enabling them to benefit from innovative digital features and efficient back‑office processes that have helped achieve Starling's success. As a company, everyone is expected to roll up their sleeves to help deliver great outcomes for our clients. We are an engineering‑led company and we're looking for people who will be excited by the potential for Engine's technology to transform banking in different markets around the world. Our purpose is underpinned by five values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Engine – our preference is that you're located within a commutable distance of our offices so that we're able to interact and collaborate in person.

Mobile Engineering Highlights

• Working as a Mobile QA
• Leading the Android Team
• Engine by Starling Careers Page

We are looking for engineers at all levels to join the team. We value people being engaged and caring about customers, caring about the code they write and the contribution they can make to banking around the world. People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Engine, to continue changing banking for good.

Roles & Responsibilities

• Contribute to our award‑winning platform and internal tooling
• Build new features and products from scratch in a configurable way
• Share your knowledge with those around you, contributing to our learning culture
• Own your projects, working in small teams across the bank to collaboratively deliver
• Aim for greatness in everything you do, staying curious and inquisitive
• Be part of a scaling team and organisation as we change banking for good

Our iOS application is entirely written in Swift. It is highly modular and we use MVVM‑C architecture to maximise code reusability and testing. We also value simplicity over complexity, fewer moving parts means fewer faults and easier comprehension.

Technical Stack

• RxSwift – as our reactive programming framework
• SnapKit – as our auto‑layout DSL, though we have an in‑house framework built on top of SnapKit which allows us to write declarative, SwiftUI‑like layout code for UIKit
• Realm – as the application main persistence layer
• Sourcery and SwiftGen – for various code generation tasks
• SwiftFormat, SwiftLint and Danger – to enforce high code quality standards
• Etc.

Developer DNA

We also built in‑house tools and frameworks as developer productivity and automation is paramount to us.

Candidate Profile

• Want to work on a feature‑rich mobile app with millions of customers
• Can produce robust, well tested code that will give our customers the reliability that they need
• Care about the product, the user experience and the design
• Think (like us) that a small number of empowered developers is the right way to deliver software
• Our application is built with UIKit, knowledge of its concepts and components is a must
• Experience with RxSwift or reactive programming is a plus but not required

Interview Process

Interviewing is a two‑way process and we want you to have the time and opportunity to get to know us, as much as we are getting to know you! Our interviews are conversational and we want to get the best from you, so come with questions and be curious. In general you can expect the below, following a chat with one of our Talent Team:

• First interview: ~45 minutes
• Take‑home technical test (no time limit)
• Technical face‑to‑face: ~2 hours
• Final interview: ~45 minutes, You may be put off applying for a role because you don't tick every box. Forget that! While we can't accommodate every flexible working request, we're always open to discussion. So, if you're excited about working with us, but aren't sure if you're 100% there yet, get in touch anyway. We're on a mission to radically reshape banking – and that starts with our brilliant team. Whatever came before, we're proud to bring together people of all backgrounds and experiences who love working together to solve problems.
