About the Role
Introducing Starling – the first and leading digital bank in the UK. Our vision is simple: regain trust in banking by building an innovative, customer-first platform that embraces technology while treating people fairly.
As an engineering team, we operate like a fast-growing tech company with a lean, open structure that empowers everyone to drive disruptive change. Innovation, collaboration, and customer obsession sit at the core of everything we do.
Our mission aims to demystify money for everyone using Kotlin, RxJava, MVVM, Dagger, and Realm—building the tools and improving the Android app. New features and app updates are released every week.
If you want to work with the latest Android technologies, make a real-world impact, and drive change in fintech, this role is for you!

- hybrid working with a preference for commutable distance from our offices
- 1 day minimum on-site per week (or more, if you choose)
- 25 days (plus flexible use of public holidays + 1 extra for your birthday)
- up to 5 extra days off annually (trade days countrywide)
- 16 hours paid volunteering time
- enhanced pension (salary sacrifice scheme), life insurance (4x salary), and group income protection
- private medical insurance with mental health and cancer care support
- partner discounts with Waitrose, Mr&Mrs Smith, and Peloton
- generous family-friendly policies
- refer-a-friend incentives + Perkbox membership (shop discounts, health platform, weekly perks)
Your Key Responsibilities
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Build, design, and innovate continuously, from day one (collaborate through designs, code commits, CI automations, and Android lifecycle processes)
- Take full ownership of projects, from writing clean and maintainable code to shipping features
- Prioritise accessibility and security, ensuring new implementations adhere to security and accessibility best practices
- Write UI/E2E tests using Espresso and unit tests using JUnit; patch features and bugs rigorously
- Collaborate with teams to build all aspects of the end-to-end development for Android features
- Automate releases at scale via our custom tooling for internal workflows and app store approvals
- Contribute to sprint reviews, challenge teams with proposed solutions, and continuously improve the app

Why You’d Thrive Here
