Job description

Senior Backend Engineer (Remote)

About InvestEngine

We’re a London-based fintech on a mission to make ETF investing simple and accessible. Over 100,000 clients have trusted us with over £1.5 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

What We’re Looking For

• 4+ years of experience in backend development
• Strong Python skills and deep knowledge of Django (or similar frameworks)
• Solid understanding of relational databases, caching, and high‑performance backend systems
• Experience with REST APIs, service design, and distributed systems
• Ability to navigate ambiguity and take ownership of architectural decisions
• Familiarity with Git, CI/CD practices, and modern development workflows
• Strong communication and problem‑solving skills
• English (B2 level or higher) and fluent Russian

Nice to Have

• Experience working in fintech, regulated industries, or internal B2B tools
• Familiarity with AWS, Docker, and message brokers (e.g. RabbitMQ, Kafka)
• Contributions to open source or personal side projects

How We Work

We’re a lean, collaborative team where developers influence architecture, product direction, and engineering culture. You’ll have autonomy, trust, and support — without micromanagement or bureaucracy. We focus on building meaningful, maintainable systems that scale with the business.

What We Offer

• Impact from day one — work on business‑critical systems and drive meaningful change
• Strategic growth opportunities — shape long‑term technical direction and scale our platform
• Modern tech stack — Python 3.11, Django, MySQL, Redis, AWS, GitHub, TeamCity
• Remote‑first and flexible — work from anywhere, at your own pace
• Unlimited vacation — take time off when you need it, no fixed limits
• Supportive team — thoughtful, skilled colleagues who care about quality and results

Hiring Process

1. Intro call with our Talent team
2. Technical interview with the Backend team
3. Final conversation with our CTO

Straightforward and fast — typically 1–2 weeks from start to offer.
