Job description

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


Deep production experience with Kafka: confident reasoning about consumer-group rebalances and their impact on in-flight processing, offset-commit strategies under retries and duplicate delivery, and the limits of "exactly-once" semantics


Experience designing idempotent, retry-safe handlers for at-least-once pipelines: transactional outbox, idempotency keys, and deduplication


Experience building services with gRPC or similar RPC frameworks


Strong knowledge of relational databases such as MySQL or PostgreSQL, plus production experience with at least one NoSQL technology at scale, such as DynamoDB, MongoDB, or Redis


Hands-on experience running services on Kubernetes and AWS/GCP: deployment, autoscaling, resource limits, and production debugging


Production operations experience: on-call ownership of a high-load system, including incident response, impact assessment, root-cause analysis, and post-incident improvements


Nice to Have


Experience with ClickHouse or other columnar/analytical databases


Experience with multi-region / failover architectures: data replication, regional isolation, and graceful degradation


Practical use of AI coding agents such as Cursor or Claude Code as part of daily development: effective prompting, reviewing, and validating AI-generated code


Understanding of application security and industry best practices


Gambling domain experience
