Frontend Engineer (Full Stack)

Frontend Engineer (Full Stack)

We are looking for an experienced Frontend Engineer to come and join our close-knit agile delivery team building iterative experiments that consistently seek to improve our product and deliver impact for our users.

You will love working in a high-performance, entrepreneurial environment that values the craft of building cutting-edge products and solving complex problems. You'll be joining a growth squad as the sole engineer on the team (besides the engineering manager), focusing on building experiments that give our users the most personalised experience; helping them improve their financial wellbeing and make finance work for them.

We are searching for someone who is a self-starter and really embeds themselves in the problem space we work in - you won't only build solutions, you will also provide ideas, alongside your peers, that then go live in front of millions of our users.

For more information on our tech stack check out our 2025 Tech Radar , how we work is summarised in our Engineering Principles and we have many other Tech Blogs on Medium.

What you will be doing:

• Design, build, and maintain full-stack solutions using Node.js and TypeScript, delivering data-driven user interfaces and backend services. You will spend most of your time delivering code on the server-side; occasionally jumping into the client side when components or capabilities need building or extending.
• Build intuitive client UX utilising design systems and server-driven UI frameworks.
• Optimise and scale databases for large-scale applications, leveraging SQL, PostgreSQL, and indexing strategies to ensure performance and maintainability.
• Work closely with expert colleagues who will implement, monitor, and optimise real-time data pipelines with Kafka, ensuring robust message handling and distributed system performance to power your features.
• As the sole engineer on the team, you will have the opportunity to take full ownership and lead the delivery of technical projects from ideation through to production.
• Lead the deployment and maintenance of production-grade code and databases across multiple global markets.
• Monitor post-release performance, leveraging tools for reliability and system health.
• Collaborate in an Agile environment, mentoring team members and those of other specialisms and fostering a culture of learning and continuous improvement.
• Contribute to the growth of our technology by driving improvements in standards, tools, and processes.

Skills we'd love you to have

• Strong knowledge of JavaScript, TypeScript and React.
• Knowledge of SSR frameworks such as Remix or Next.js
• Experience building services using Node.js and technologies like Fastify or Express.js
• Experience working in an Agile Scrum environment
• Strong collaboration skills and impulse to share your knowledge across the Frontend team and the wider tech community
• Ability to contribute to large projects with multiple engineers working on them
• You live for unit and functional testing, using tools such as Jest, React Testing Library and Enzyme
• Good knowledge of build tools such as Webpack, and/or RollUp
• Desire to get involved with deployment pipeline technologies like AWS and Docker
• Understand and drive build processes and CI tooling (e.g. Jenkins, Circle CI)
• You have opinions on what technologies and standards we should be using now and in the future - we always want to hear new ideas.
