Principal Backend Engineer

Our mission is to enable everyone to build wealth

We reinvent how trading and investing work by creating exceptional products people love.

Trading 212 is built by highly driven people who strive for excellence and value freedom.

Today, we serve over 4.5 million clients, with more than €30 billion in assets under management - a testament to the scale and trust we’ve built in just a few years.

We are looking for experienced and driven principal software engineers to help us scale and innovate.

What You’ll Do

Lead the technical development of an entire business domain. Engage in forming requirements, design the architecture, and lead the entire software development life cycle.
Lead a compact, autonomous, cross-functional team with short release cycles - we rely on agile, independent teams of sharp and driven people with just the right amount of processes to steer off anarchy and not sacrifice velocity. Find the most valuable strengths of your teammates and provide them with mentorship in order to develop them further.
Develop solutions by taking a holistic approach to problem-solving - we expect you to understand the business problems, our service architecture and the underlying technologies and infrastructure and take everything into consideration.
Develop for performance, scale and resilience – your code will run in an uncompromising environment. Downtime, latency and data loss are intolerable.
Take initiative to identify areas of product improvement.

What You Need To Have

Experience in leading the development and subsequent release of a complex/high-demand client-facing product.
Experience in leading, coaching, and mentoring software engineers towards delivering high-quality software together with them.
Experience with developing services in a microservice architecture.
Advanced knowledge of at least two programming languages.
Deep understanding of RDBMS, messaging brokers and in-memory data storages.
