About InvestEngine
We’re a London-based fintech on a mission to make ETF investing simple and accessible. Over 150,000 clients have trusted us with over £3 billion in assets — and we’re just getting started. We’ve been featured by MoneyWeek, Finder and Forbes, and we’re growing fast with big ambitions.
About the Role
We’re looking for a Senior Backend Developer to join our Backoffice team and strengthen our technical foundation as we grow. This role focuses on architecture, system stability, and scaling internal platforms that power critical business operations.
You’ll work on complex backend challenges, design clean and scalable services, and collaborate with product and business teams to bring ideas to life. You’ll play a key role in shaping technical direction and making high-impact decisions — without people management responsibilities.
What You’ll Do
- Design, develop, and maintain backend services in Python 3.11 using Django / DRF
- Lead architectural discussions and contribute to long-term technical strategy
- Work with MySQL and Redis to optimize performance and scalability
- Build and improve RESTful APIs for internal and external integrations
- Continuously improve system performance, reliability, and scalability as we grow
- Collaborate with Product, Compliance, and Business teams to deliver impactful features and automate back office processes and workflows.
- Investigate and resolve production issues, identify bottlenecks, and reduce tech debt
- Apply best practices in Git workflows, CI/CD pipelines (TeamCity, GitHub Actions), and code quality
- Drive improvements in our architecture, development processes, and internal tooling

- English (B2 level or higher) and fluent Russian
