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
What We Offer:
- Competitive Salary* Quarterly Bonuses* Unlimited Paid Time Off* Unlimited Paid Sick Leave* Remote & Flexible Working* Private Medical Insurance* Financial Support for Life Events* Professional Development Budget* International Exposure* Regular Company Events*\*Benefits may vary depending on location and contractual agreement*
