Senior Golang Developer

Who we’re looking for

• 4–5+ years of commercial experience using Go as the primary programming language, with a deep understanding of its internals, including memory management, scheduler, maps, channels, garbage collection, sync.Pool, and atomic operations.
• Proven experience designing, building, and operating large-scale distributed systems and microservices in high-load production environments.
• Strong expertise in PostgreSQL or MySQL, including query optimization, indexing strategies, replication, clustering, and resolving lock contention in multi-terabyte databases.
• Hands-on experience with messaging platforms such as NATS and Apache Kafka, along with a solid understanding of their architectural trade-offs, including latency and persistence.
• Solid understanding of Linux internals, networking fundamentals, virtualization, and containerization technologies (Docker/Kubernetes), with the ability to troubleshoot production issues effectively.

What you’ll do

• Drive key architectural decisions within a microservices ecosystem, evaluate technology choices, and define integration patterns and best practices.
• Profile applications, optimize CPU and memory utilization, fine-tune Go's garbage collector, and leverage concurrency primitives to achieve maximum performance.
• Design efficient data models, optimize complex queries and indexing strategies in PostgreSQL/MySQL, and ensure high performance under intensive read/write workloads (thousands of QPS).
• Build observability into services by implementing metrics, logging, and distributed tracing. Participate in production incident investigations and perform root cause analysis across application code, networking, and operating system layers.
• Conduct thorough code reviews, share technical expertise, mentor engineers, and promote engineering best practices across the team.
• Collaborate closely with DevOps, QA, Product, and other engineering teams to deliver production-ready features quickly, safely, and reliably.
