Job Description

We're looking for a Senior React Native Engineer to join our Client Platform team to push hard on AI across our React Native and UI engineering practice: AI-assisted coding, testing and deployments, shift left on security, defect triage and observability, and the internal tooling that connects our AI tools safely to Jira, GitLab, and our CI/CD pipeline. You'll bring strong React Native and front-end UI expertise, with a sharp eye for component architecture, performance, and cross-platform consistency. This is a hands-on role. You'll build tooling yourself, and you'll help set how your team adopts it.

This role suits engineers with a strong grounding in software engineering practice: test-driven development, pair programming, and real ownership of systems from design through to production support, with real depth in Java or a comparable backend service ecosystem. The fundamentals matter most: engineers who can write their own tests, review their own designs, and catch their own defects, and who use AI to extend that practice further and faster. Growing into the person the whole group comes to for technical judgement is part of the role.

The long-term goal is a pipeline where AI agents handle the bulk of coding support, testing, and triage end-to-end, largely unattended, with engineers stepping in for genuine judgement calls and exceptions. We're early on that path today, and we want someone in this role who treats the destination as real and pushes their team toward it deliberately.


What you'll do:

  • Apply highly skilled React Native and UI expertise to improve application performance, architecture, and code quality across the Client Platform.
  • Build and maintain internal tooling that embeds AI into day-to-day engineering work: coding assistants, AI-assisted test generation, deployments, and defect triage.
  • Contribute to observability in the AI-assisted pipeline, so every stage shows what the tooling is doing, catching, and missing.
  • Identify manual steps in coding, testing, and release that can run largely unattended, and help build the automation to get there.
  • Split work into small, releasable pieces that ship continuously.
  • Work closely with a product person on your product domain, so what you build is grounded in real delivery.
  • Treat improving ways of working and driving AI adoption as a fundamental, ongoing part of delivering value.
  • Work with the test and PM function to bring AI into the testing pipeline: exploratory test generation, defect clustering, flaky-test detection, and smarter prioritisation of what to test.
  • Evaluate and help roll out LLM-based developer tools, for example Claude Code and similar, integrating them safely with our Jira, Confluence, and GitLab environments.
  • Follow and help refine standards for responsible AI use in the SDLC: data handling, prompt hygiene, and guardrails around production and customer data.
  • Mentor less experienced engineers on effective use of AI tooling, as well as React Native architecture and performance best practices.
  • Work with security and compliance to make sure AI tooling meets IG's regulatory and data-handling requirements.
  • Track the metrics that show whether AI tooling is helping: cycle time, defect escape rate, test coverage, delivery turnaround. Iterate based on what the data shows.

What you'll need for this role:

  • Extensive background as a Software Engineer, with demonstrated technical judgement on production systems.
  • Highly skilled in React Native and UI development, with a strong track record of improving performance and architecture in production applications.
  • Strong fluency in test-driven development and pair programming as working disciplines.
  • Real ownership experience: you've designed features or systems, built them, deployed them, and supported them in production.
  • A genuine appetite for aggressive automation. You get energised by removing manual steps entirely.
  • Some experience evaluating or using LLM-based developer tools in a real engineering environment.

Preferred Qualifications

  • Experience with MCP, agentic tooling, or Spec Driven Development.
  • Familiarity with the Atlassian ecosystem (Jira, Confluence) and its APIs.
  • Prior experience in financial services, trading platforms, or another regulated, high-reliability environment.

Company Benefits

  • Competitive salary
  • Flexible Benefits Package on top of your salary (x%)
  • Private medical cover for you and your family
  • Life insurance
  • Contribution to gym memberships
  • 25 Days holiday, with 1 additional day off to celebrate your Birthday & 2 additional days off a year for voluntary work (28 in total)
  • The option to buy or sell holiday days
  • Unlimited access to the LinkedIn Learning Platform
  • A comprehensive global and local onboarding process
  • Employee-led LGBTQ+, Women’s, Black and Parents & Carers networks with an annual budget for organising events & projects that foster an open, diverse and inclusive culture
  • Option to participate and create ESG initiatives based on IG Brighter Future Fund

Job Description

Starling is the UK’s 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’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. 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 are looking for talented data professionals 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 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.

Company Benefits

  • 33 days holiday (including flexible bank holidays)
  • An extra day’s holiday for your birthday
  • 16 hours paid volunteering time a year
  • Part-time and/or flexible hours available for most roles

  • Hybrid/remote working
  • Private Medical Insurance with VitalityHealth including mental health support and cancer care. Partner benefits include discounts with Waitrose, Mr&Mrs Smith and Peloton
  • Generous family-friendly policies
  • Varied social groups set up and run by our employees
  • Perkbox membership giving access to retail discounts, a wellness platform for physical and mental health, and weekly free and boosted perks
  • Access to initiatives like Cycle to Work, Salary Sacrificed Gym partnerships and Electric Vehicle (EV) leasing

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!

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
  • Stage 3 - 45 min final with an executive and a member of the people team
