Job Description

We are searching for an experienced Senior Flutter Engineer to work in a product centric role, helping us bring feel good investing to life. You will help build the Flutter app that is replacing our long-standing native iOS and Android apps, serving a D2C business of over 500,000 customers, a large proportion of whom manage their investments through the app. You will put users at the forefront of the way you think and be passionate about great user experience and user interface design. You will be able to deliver tested, resilient, and performant code against a fast-paced environment. Your role will be pivotal in helping us achieve our mission by developing, shaping, and iterating our customer facing Flutter applications. We work hybrid, with at least 50% of your time in the office.

This is a hands-on individual contributor role in a cross functional team. You won't line-manage, but you will have a strong influence on how the team builds - through pairing, code review, mentoring and the technical standards you set.


Responsibilities

  • Architect solutions with your team and write the technical documents that define what we're building.
  • Write well-formulated, testable and readable code using appropriate software paradigms.
  • Multiply the team's output - unblock others, make the difficult architectural calls, and leave the codebase easier to work in than you found it.
  • Ensure accessibility is at the forefront of our approach.
  • Mentor and develop others in the team, through pairing, reviewing pull requests, and advocating development standards to be followed by existing and new team members.

How we build

  • A Flutter monorepo - one app plus a set of internal packages.
  • Layered Clean Architecture, enforced in CI.
  • A design system built from Figma design tokens and catalogued in Widgetbook.
  • A backend-for-frontend that drives parts of the UI, so screen composition can change without an app release.
  • GitHub Copilot for every engineer, with repo-level instructions and custom skills we've built to keep AI output aligned with our architecture and patterns.

Competence, knowledge and skills


Technical skills

You've shipped production mobile apps to real customers through full app store release cycles, and you're the engineer others turn to for architecture decisions and code review. Your Flutter experience might come from production work, or from a strong native background plus substantial Flutter projects.

  • Strong understanding of mobile DevOps practices, including CI/CD pipelines, release management, and app store deployment processes.
  • Advanced software engineering skills, including writing high-quality code, conducting thorough code reviews, and proactively identifying anti-patterns and maintainability risks.
  • Comfortable using AI coding tools to work faster, with the judgement to know when to rely on them and when not to. You own the code you ship, however it was produced.
  • Proven ability to diagnose, troubleshoot, and resolve defects across the mobile application lifecycle.
  • Solid knowledge of reactive state management patterns and how to apply them in mobile architectures.
  • Strong grasp of software architecture principles, with the ability to communicate and document designs clearly for both technical and non-technical audiences.
  • Experience building products on top of a design system - consuming and extending shared components rather than reinventing them, and knowing when something belongs in the shared library rather than in your feature.

How you work

  • Strong passion for mobile UX and building inclusive products, with working knowledge of accessibility best practices and relevant standards.
  • A clear communicator who listens well and collaborates deliberately across product, design and engineering - comfortable working autonomously, and equally comfortable inside a cross-functional team.
  • High ownership: you turn ambiguous problems into shipped solutions, prototyping early to validate ideas, and take the initiative on improvements rather than waiting to be asked.

Nice to have

  • Native Android (Kotlin) or iOS (Swift) experience. Our legacy native apps are still live, and a native background helps when working out what existing behaviour we need to carry across.
  • Experience working in finance, investing, or another regulated domain.
  • Experience with backend-for-frontend architectures, where the backend shapes what the app renders.
  • Experience building or owning a design system or shared component library.

Company Benefits

  • Competitive starting salary
  • Generous holiday allowance of 25 days, increasing up to 30 days with service, plus bank holidays
  • Holiday buy/sell scheme
  • Hybrid working policy
  • Casual dress code
  • Discretionary bi-annual bonus
  • Contributory pension scheme
  • Buy as you earn share scheme
  • Free shares scheme
  • Paid study support for qualifications
  • Enhanced maternity/paternity scheme from day one
  • Bike loan
  • Season ticket loan portal
  • Discounted PMI and Dental
  • On-site gym and personal trainer led classes
  • Paid volunteering opportunities
  • Free social events and more

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
  • Salary sacrifice, company enhanced pension scheme
  • Life insurance at 4x your salary
  • 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

Full details are available on our careers site

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
  • Stage 3 - 45 min final with an executive and a member of the people team
