Software Engineer, Hargreaves Lansdown

• 2+ years of professional experience with React Native or React
• Strong TypeScript skills and a commitment to writing clean, maintainable code
• Someone who writes tests because they value correctness, not because they’re told to
• Ability to pick up new tools and technologies quickly
• Curiosity about how things work at the platform level - architecture, tooling, patterns - not just feature delivery
• Strong React developers without RN experience are welcome; the mobile‑specific parts can be learned on the job
• We know that sometimes people can be put off applying for a job if they don't tick every box. If you're excited about working for us and have most of the skills or experience we're looking for, please go ahead and apply. We’d love to hear from you!

Desirable

• HL is building a brand‑new React Native platform from the ground up — a foundational mobile architecture that every future mobile team at Hargreaves Lansdown will build on. You’ll be joining a small, focused team responsible for creating this platform, shaping the tools, patterns, and developer experience that power the next generation of HL’s mobile apps
• Instead of simply picking up tickets and building isolated screens, you’ll help define the core architecture, testing strategy, design system, and developer tooling that underpin the entire mobile ecosystem. This is a rare opportunity to work at platform level within one of the UK’s largest investment platforms, used by over a million clients
• You’ll work closely with two senior engineers to design, build, and validate the foundations of HL’s new React Native platform. This includes building the first features that prove out the architecture, creating the testing and tooling infrastructure, and supporting other teams as they begin adopting the new system
• You’ll take ownership from concept to implementation, write clean and maintainable TypeScript, contribute to architectural decisions, and help shape the long‑term direction of HL’s mobile technology
• Build the first features on the new React Native platform, validating the architecture before wider adoption
• Create the testing infrastructure, including E2E tests, mock APIs, and shared utilities
• Develop developer‑experience tooling such as project scaffolding, linting configurations, and onboarding guides
• Build accessible design‑system components used across every screen in the app
• Work with a real GraphQL API powering a financial application used by over a million people
• Support other teams as they begin building on the platform you helped create
• This is a full‑time role, working 37.5 hours per week, Monday to Friday

• End Date: April 26, 2026
• Stage 1 – Discussion with our Hiring Manager (30 mins) A conversation to explore your background, motivations, and fit for a platform‑focused engineering role
• Stage 2 – Technical Interview (60–90 mins) A deep dive into your React/React Native expertise, architecture thinking, and problem‑solving approach
