Descripción del empleo

Our mission

Our mission is to enable everyone to build wealth. We reinvent how trading and investing work by creating exceptional products people love. Fostering a culture of excellence and high velocity is the key to our success. Today, we serve over 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.

What You’ll Do

• 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.
• Engage in forming requirements, design your implementation, code it, test it, deploy and monitor it – the full SDLC is led by our software engineers. You have full ownership of your code and you have to maintain it in good shape and refactor it when there’s a good opportunity for improvement.
• Develop for performance, scale and resilience – your code will run in an uncompromising environment. Downtime, latency and data loss are intolerable.
• Work in compact, autonomous teams 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.
• Learn from your colleagues and share your knowledge with them. We have to grow as the company grows and mutual honest feedback is one of our most reliable weapons.

What You Need To Have

• Experience with developing services in a microservice architecture. To meet our business needs we’ve built a highly-scalable and performant system consisting of 200+ microservices.
• Good familiarity with common communication protocols. We expect you to be comfortable with using HTTP/WebSockets & AMQP communication and have the ability to decide when to use one over the other.
• Prior experience with at least one commonplace web framework, no matter the language. Our system is language-agnostic and we give the engineers the opportunity to choose the specific language based on its appropriateness for the particular task. The microservice architecture allows us to use the newest technologies and we're constantly striving to keep a healthy balance between an up-to-date system and a battle-tested and familiar one.
• Deep understanding of RDBMS concepts. We expect you to know about indexing, transactions, isolation levels, locking mechanisms and you should be able to design high-performance databases.

Nice to have

• Experience with in-memory databases (e.g. Redis/Memcached).
• Ongoing or completed CS education.

Our tech stack

• Languages and frameworks: Java 17 - Spring, Go, NodeJS - TypeScript
• Databases: PostgreSQL, MariaDB, Redis, Elasticsearch, TimescaleDB, ClickHouse
• Messaging: Apache Kafka
• Web servers: Nginx, HAProxy
• Version control: Git, GitLab
• Containerization: Docker
• Logs & Monitoring: Grafana, Kibana, Telegraf

What we offer

• Challenges that will help you grow and realize your potential really fast
• Opportunity to make a big Impact - you will build innovative services used by millions of investors to build wealth
• Work with smart, spirited, helpful, high-performing colleagues with a common goal
• An environment where nothing is set in stone
• Appreciation for your talent and ideas
• Generous remuneration package including annual bonuses
• Excellent social benefits package, including private health insurance, sports card and 25 days of paid vacation per year
