About the Role
We’re looking for a Senior Backend Developer who thrives in a deeply hands-on environment and enjoys being close to the code on a daily basis. This role is heavily focused on building, optimising, and scaling backend services in a high-load system where performance and reliability are critical.
You’ll be working on complex, real-time challenges at the core of our platform - improving latency, ensuring high availability, and making systems more efficient at scale. This is not a coordination-heavy role; it’s for someone who enjoys writing production code, solving tough engineering problems, and seeing the direct impact of their work.
If you’re product-driven, take ownership, and prefer a “build first, improve fast” approach while working on systems where every millisecond matters - this role will feel like home.
Key Responsibilities
Work as part of a cross-functional team owning a core product within the platform
Design, build, and deliver new backend features end-to-end in a distributed environment
Write high-quality, production-level code daily, contributing directly to a high-load, scalable system
Take ownership of services handling financial transactions at scale, with a strong focus on reliability and accuracy
Proactively suggest and implement improvements in architecture, processes, and development practices
Participate in code and architectural reviews to maintain high engineering standards
Solve complex business and technical challenges with pragmatic, efficient solutions
Participating in on-call rotations within the squad to ensure the reliability and availability of our systems
Play an active role in ongoing tech transformation initiatives across the platform
Collaborate closely with engineers, product, and other stakeholders to deliver impactful solutions used by millions globally
Requirements
Solid experience with Node.js/TypeScript is ideal, but we also welcome experts in other OOP languages such as Java, Python, C++, C#, or Go.
Strong understanding of asynchronous programming techniques

Knowledge of relational databases (MySQL, PostgreSQL), columnar databases (ClickHouse), and NoSQL technologies (DynamoDB, MongoDB)
Skilled in developing and maintaining end-to-end and unit tests

Degree in Computer Science or related field
