Senior Backend Engineer (Core Team)

About This Opportunity

We are representing a confidential gaming technology organization seeking a Senior Backend Engineer to join their core platform team. This is a hands-on, code-focused role for engineers who want to work on high-load distributed systems where performance and reliability are paramount.

You'll spend your days building and optimizing backend services that handle real-time challenges at massive scale. This position is ideal for engineers who prefer writing production code and solving complex technical problems over coordination-heavy work. If you're energized by systems where every millisecond counts and you take pride in owning services end-to-end, we'd like to hear from you.

Location: Europe, Ukraine (Remote)

Responsibilities

• Design, build, and deliver new backend features end-to-end in a distributed environment as part of a cross-functional product team
• Write high-quality, production-level code daily for high-load, scalable systems
• Own services handling financial transactions at scale with 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
• Participate in on-call rotations to ensure system reliability and availability
• Collaborate closely with engineers, product stakeholders, and other teams to deliver solutions used by millions globally
• Play an active role in ongoing tech transformation initiatives across the platform

What We're Looking For

Required Skills and Experience:

• Solid experience with Node.js/TypeScript, or expert-level proficiency in other OOP languages such as Java, Python, C++, C#, or Go
• Strong understanding of asynchronous programming techniques
• Deep production experience with Kafka: understanding consumer-group rebalances, offset-commit strategies under retries and duplicate delivery, and exactly-once semantics limitations
• Experience designing idempotent, retry-safe handlers for at-least-once pipelines including transactional outbox patterns, idempotency keys, and deduplication
• Experience building services with gRPC or similar RPC frameworks
• Strong knowledge of relational databases (MySQL or PostgreSQL) plus production experience with at least one NoSQL technology at scale (DynamoDB, MongoDB, or Redis)
• Hands-on experience running services on Kubernetes and AWS/GCP: deployment, autoscaling, resource limits, and production debugging
• Production operations experience including on-call ownership of high-load systems, 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 including data replication, regional isolation, and graceful degradation
• Practical use of AI coding agents (Cursor, Claude Code) as part of daily development workflow
• Understanding of application security and industry best practices
• Gaming or gambling domain experience
