Senior Go Developer

Accountabilities: • Design, develop, and maintain robust, scalable, and reliable backend services aligned with evolving product and business requirements.

• Lead technical research, architecture design, and implementation of backend services and new functionality.

• Design solutions for high-load distributed systems while balancing performance, reliability, scalability, and maintainability.

• Work with synchronous and asynchronous service communication, including gRPC and message brokers, while considering delivery guarantees, idempotency, and load-balancing trade-offs.

• Design and optimize data models, database schemas, queries, indexes, replication, partitioning, and other scaling strategies.

• Implement and maintain caching strategies and distributed caching solutions using technologies such as Redis.

• Own backend services throughout their production lifecycle, including deployment, monitoring, troubleshooting, maintenance, and continuous improvement.

• Establish and maintain observability capabilities covering metrics, logging, dashboards, distributed tracing, alerting, and Go profiling.

• Participate actively in code reviews and architectural discussions while helping improve the overall technical quality of backend services.

• Collaborate with engineers and other teams to deliver cohesive and effective technical solutions.

• Mentor and guide other engineers, sharing best practices and promoting high standards for software development.

• Write clean, maintainable, and testable code supported by appropriate unit and integration test coverage.

Requirements:

• 5+ years of commercial backend engineering experience in production environments.

• Strong professional experience with Go, including concurrency, synchronization primitives, context propagation, goroutine lifecycle management, and graceful shutdown patterns.

• Proven experience building and supporting high-load distributed systems.

• Recent experience developing products with complex business logic and frequently evolving requirements.

• Strong SQL and data modeling skills, including schema design, joins, aggregations, composite indexes, data type selection, query analysis, replication, partitioning, and sharding.

• Hands-on experience with MySQL or PostgreSQL.

• Strong understanding of caching strategies, including Redis, cache-aside patterns, cache warm-up, and background refresh.

• Experience with synchronous and asynchronous inter-service communication, including gRPC and message brokers, delivery guarantees, idempotency, and load-balancing considerations.

• Deep understanding of microservice architecture patterns, client-server interactions, and their respective trade-offs and limitations.

• Hands-on experience with observability practices, including metrics, logging, distributed tracing, alerting, and Go profiling with pprof.

• Understanding of non-functional requirements, including SLA, SLO, and SLI concepts.

• Experience with Docker, Kubernetes, CI/CD pipelines, and cloud platforms.

• Strong commitment to writing maintainable, testable code with solid unit and integration test coverage.

• Proficiency with Git and modern code review workflows.

• Ability to explain architecture and technical decisions at different levels of depth.

• Strong problem-solving skills and the ability to turn ambiguous requirements into clear solutions and actionable workloads.

• Experience with event-driven architectures using Kafka, NATS, RabbitMQ, or similar technologies is a plus.

• Familiarity with infrastructure-as-code tools, advanced Go performance optimization using pprof and trace, and AI-assisted development tools is beneficial.

• Intermediate English proficiency, with the ability to communicate effectively during regular client interactions.

• Ability to work as a B2B contractor in the country of current residence.

Benefits:

• Fully remote contract position.

• B2B contract structure with one contract and one monthly invoice.

• Rate negotiated according to seniority and client budget.

• Monthly payment aligned with the client payment schedule, typically within 30 days.

• Contract governed by the applicable laws of your country of residence.

• Administrative support for client-side documentation, including MSA, NDA, and invoicing.

• Opportunity to work on a large-scale mobility and urban services product.

• Exposure to high-load distributed systems, modern cloud infrastructure, Go, Kubernetes, Redis, and SQL.

• Opportunity to contribute to architecture, technical standards, observability, and engineering best practices.

• Collaboration with distributed engineering teams in a product-focused environment.
