Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.
We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.
Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!
The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling 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 Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. In Technology, we're asking that you attend the office a minimum of 1 day per week.
Our Engineering Environment
Starling engineers are excited about helping us deliver new features, regardless of what their primary tech stack may be. Hear from the team in our latest blogs or our case studies with Women in Tech.
We value people being engaged and caring about customers, caring about the code they write and the contribution they make to Starling. 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 Starling, to continue changing banking for good.
Requirements
We're seeking a highly motivated and experienced engineer to play a key role in our Customer Service Engineering Group. You should have a strong understanding of delivering robust and scalable code, applying best practices, and a proven track record of delivering high-quality software. Experience with AWS and Postgres is highly desirable.
We’re open-minded when it comes to hiring and we care more about aptitude and attitude than specific experience or qualifications. We are very open about how we deliver software. For the most part we code in Java, and though we are looking for someone with at least 7 years of commercial experience with Java, you need not be an expert! We believe in clean coding, simple solutions, automated testing and continuous deployment. If you care enough to find elegant solutions to difficult technical problems, we’d love to hear from you.
The main part of our Tech Stack is listed below, we don't ask that you have experience in all of this, but if you do, that's great!
The team
The Customer Service Engineering group is all about making things better for our customers. We use the latest tech to build solid solutions that let customers help themselves, easily find out what the bank offers, and give our Operations teams the best tools to help customers quickly and effectively.
