Job description

About Freetrade

Freetrade's mission is to become the default place to invest. Investing has been too complicated and expensive for too long, keeping millions from making the most of their savings. We're changing that. We're building our team and looking for people who are excited to reshape how our customers invest and grow their wealth. If you're driven by solving complex problems and building innovative products, you'll fit right in. 2026 is a big year for us. Last year, we announced a game changing deal to become part of the IG Group. We'll continue to operate as an independent business while gaining access to the resources and support of an established leader in the space. This year, we're accelerating our roadmap and taking our products to the next level. We're building new features like mutual funds, bonds, and family investment tools. We're also exploring how we can leverage AI to deliver an even better experience for our customers. Freetrade Engineers play a pivotal role in developing and maintaining a robust, scalable platform used by thousands daily. We tackle big technical challenges, drive innovation, and build solutions that make a real impact. Here, your code doesn't just run - it powers the decisions of investors across the UK.

About the role

As part of our dedicated mobile engineering team, you will work on implementing new features. In collaboration with design, product and QE teams you will craft user experiences that will delight our customers. You will also help guide priorities around platform issues, technical debt, patterns, and architecture, ensuring we deliver a high-quality app and an excellent developer experience. We have recently rebranded key parts of the app, creating a new design system from scratch built with Jetpack Compose, and have started transitioning to a modern, unified GraphQL API using Apollo.

What you'll do

• Lead the design and delivery of new features, alongside improving and maintaining the Freetrade Android app, ensuring high performance, quality, security and robustness.


• Own features end to end, collaborating with backend, design, product and QA to deliver high-quality solutions.


• Set and hold a high bar for code quality through hands-on development, code reviews and effective testing.


• Resolve complex issues, address bottlenecks and reduce technical debt.


• Drive improvements in engineering standards and practices.


• Mentor and support junior engineers on design, implementation and best practices.


• Participate in a support rota to understand and resolve customer issues, including direct communication where needed.

About you

• Typically 6+ years of experience building production-grade mobile applications.


• Strong problem‑solving skills with the ability to lead technical decisions and deliver complex features.


• Deep understanding of Android architecture such as MVVM or MVI.


• Strong experience with Kotlin, Dagger, Jetpack and Compose.


• Good understanding of GraphQL and integrating with backend services.


• Experience with coroutines, flow or Rx.


• Familiarity with git and collaborative development practices.


• Understanding of CI and build tooling such as CircleCI.


• Experience mentoring and growing more junior engineers.

Our hybrid model

We work from our central London and Budapest offices on Monday, Tuesday, and Thursday, leaving Wednesday and Friday for dedicated focus time at home. We believe in the power of in-person collaboration to build a strong culture, but we know \"life happens.\" If you have caregiving or personal responsibilities that require extra flexibility, let's talk about it.

Our interview process

We keep things simple and transparent. You'll meet one of our Talent Partners for a technical screening call, typically followed by:

• Hiring Manager interview


• Live coding interview


• System design interview


• Final Values interview

We are an Equal Opportunity employer committed to a diverse and representative team. Whatever your race, religion, colour, national origin, gender, sexual orientation, age, marital status, or disability - we want to hear from you.
