Backend Engineer • Senior

Who you are

You have 5+ years of backend engineering experience, building production systems that scale effectively — you've owned services from design through deployment and have navigated the complexities of debugging distributed systems. Your expertise in Java and Spring is deep, allowing you to ship high-throughput APIs that handle millions of requests seamlessly. You understand service architecture, dependency injection, and testing strategies, ensuring that your code is robust and maintainable.

You thrive in collaborative environments, working closely with cross-functional teams to turn zero-to-one ideas into real products — your ability to communicate technical concepts to non-technical stakeholders is a key asset. You are motivated by the mission of empowering businesses through innovative financial solutions and are eager to contribute to a team that values ownership and impact.

Your curiosity drives you to dig deep into problems, using AI and other technologies to work smarter and solve challenges faster. You are humble and open to feedback, always looking for ways to improve both your work and the team's output. You are excited about tackling complex, high-visibility problems alongside exceptional teammates.

Desirable

Experience with cloud platforms like AWS or Azure would be a plus, as would familiarity with microservices architecture. If you have a background in financial technology or have worked in a fast-paced startup environment, we encourage you to apply even if your experience doesn't match every requirement.
