Job Description

We're looking for a Staff Software Engineer (Full Stack) to play a pivotal role in driving the technical success of Runna. This is a hands-on role where you'll work across multiple squads, providing architectural direction, ensuring engineering excellence, and enabling the successful delivery of features across the entire Runna platform. We have a jam packed roadmap, with countless opportunities to champion new technologies, work on meaningful problems that impact millions of runners, and improve existing architecture to elevate the whole of our engineering team.

We follow a flexible hybrid model that translates to more than half of your time on-site - 3 days per week in Runna's office based in London, UK.


What you'll be doing

  • You'll be a multiplier for the engineering team; mentoring developers, improving processes, and guiding the evolution of our systems as we scale. We're looking for someone who is not only technically excellent, but also a creative problem solver and collaborative leader who brings energy and clarity to fast-paced environments.
  • Lead the architectural design and technical strategy across multiple product teams, ensuring scalable, secure, and maintainable solutions.
  • Champion how we adopt AI across our SDLC, from agentic workflows and automated code review through to the tooling and guardrails that help the wider team ship faster without lowering the bar.
  • Drive the end-to-end delivery of key initiatives, working hands-on to build, test, and ship features across the full stack (mobile, backend, integrations).
  • Coach and support engineers by providing technical guidance, mentorship, and code reviews without creating bottlenecks.
  • Collaborate with Product, Design, and Engineering Leads to define the best solutions for user experience, balancing speed, quality, and long-term technical goals.
  • Own the release process and support a culture of reliable, continuous deployment-while enabling teams to ship confidently and independently.
  • Maintain and grow a high-performing engineering culture based on ownership, knowledge-sharing, and continuous improvement.

What you'll bring to the team:

  • 6+ years of professional experience in software engineering, with a focus on technical leadership and driving projects end-to-end.
  • Deep expertise in TypeScript/JavaScript, with a strong foundation across the full stack.
  • Hands-on experience putting AI to work in a real engineering organisation, whether that's agentic workflows, automated code review, or internal agents. You have a clear view of where it pays off and where it doesn't.
  • Familiarity shipping LLM-backed features to production, including prompt and context design, in a user facing product.
  • Broad AWS experience across serverless (Lambda, API Gateway, AppSync), containers (ECS/EKS) and managed services, with no strong attachment to one deployment model.
  • Skilled in defining and delivering features from initial architecture and design through to release, testing, and production support.
  • Able to thrive in a highly skilled, fast-paced engineering team. So far in 2026, we shipped:
    • 49 mobile app releases (iOS and Android)
    • 878 API releases
    • 552 modelling backend releases
  • Proven ability to mentor engineers, support team growth, and guide complex projects from design to release.
  • Comfortable with Infrastructure as Code tooling like Terraform, CDK, or CloudFormation.
  • Able to thrive in autonomous roles, taking ownership without heavy direction.

Bonus points if you have:

  • Experience working with cross-platform frameworks, such as React Native
  • Have hands-on experience with SwiftUI or native mobile development.
  • Are confident working with and improving CI/CD pipelines, release cycles, and deployment processes.

Job Description

Starling is the UK鈥檚 first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK鈥檚 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鈥檙e a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We鈥檙e 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. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, 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 have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.

  • An extra day鈥檚 holiday for your birthday
  • 16 hours paid volunteering time a year
  • Part-time and/or flexible hours available for most roles

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:

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
