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
Recruitment process
1. HR interview (30-45mins)
2. Interview with a Hiring Manager (45mins)
3. Technical interview with live coding (90mins)
4. Final Interview with C-level (60 mins)
