About the Team

You will join a product engineering team of backend, frontend, QA, and DevOps engineers working closely with Product and Design. The team owns its services end to end: from design and implementation to deployment, monitoring, and on-call support.

Typical Tech Stack

• Language: Go
• Databases: PostgreSQL, MySQL, Redis
• Messaging: Kafka, RabbitMQ, or NATS
• APIs: REST, gRPC, OpenAPI (Swagger)
• Authentication & Authorization: OAuth 2.0 / OIDC
• Infrastructure: Docker, Kubernetes, CI/CD (GitLab CI or similar)
• Observability: Metrics, centralized logging, distributed tracing, alerting

Nice to Have

Required:

• 5+ years of commercial backend development experience
• Strong proficiency in Go: idiomatic code, concurrency patterns, performance profiling
• Solid understanding of relational databases (PostgreSQL or MySQL): schema design, indexing, query optimization, migrations
• Experience with Redis or similar caching solutions
• Experience designing and implementing REST APIs (gRPC is a plus) and documenting them with OpenAPI/Swagger
• Understanding of microservices architecture and distributed systems trade-offs (consistency, availability, failure modes)
• Experience with message brokers (Kafka, RabbitMQ, NATS, or similar) and event-driven design
• Experience with Docker and a good understanding of Kubernetes basics
• Proficiency with Git and CI/CD practices
• Solid experience with automated testing (unit, integration)
• Understanding of application security fundamentals (OWASP Top 10, secure handling of secrets and user data, authentication and authorization basics)
• Good written and spoken English

Preferred:

• Experience with observability tooling (Prometheus, Grafana, ELK/Graylog, OpenTelemetry)
• Experience with high-load systems and performance profiling
• Experience with cloud platforms (GCP, AWS, or Azure) and infrastructure-as-code
• Experience with NoSQL databases (MongoDB or similar)
• Experience leading technical initiatives or mentoring engineers
• Experience in gaming, e-commerce, fintech, or payments domains
• Practical, up-to-date experience with modern AI tools (e.g. Claude, Copilot, Cursor) for code generation, review, and accelerating day-to-day engineering work.
