Senior GoLang Developer (Trading Systems)

We are looking for an experienced Senior Golang Developer to join our Trading Technology team and build high-performance, low-latency systems for a global Forex/CFD brokerage.

We expect the ability to independently investigate complex tasks, propose optimal architectural solutions, and proactively collaborate within the cross-functional team and with various stakeholders (Trading, IT).

This role is ideal for engineers who understand market microstructure and enjoy building high-throughput distributed systems with strict performance and reliability requirements.

Responsibilities:

Core Development

• Design and implement low-latency, high-throughput trading microservices in Go

Architecture & Performance

• Optimize performance at all levels: CPU/memory consumption, GC pressure, lock-free structures, batching strategies.
• Implement efficient concurrency patterns (SPSC/MPSC queues, worker pools, sync primitives, event-driven pipelines).
• Build resilient distributed services with failover, back-pressure handling, and graceful degradation.

Team Collaboration

• Interact with Product Owner/Business Analyst to design flows, logical schemes, algorithms.
• Conduct cross-team code reviews, propose improvements, exchange experience with peers.

Essential

• 5+ years of experience with Golang, including deep understanding of concurrency (goroutines, channels, sync, atomics).
• Strong experience implementing microservices using event-driven and RPC-based communication (NATS, Kafka, gRPC, REST).
• Experience with SQL/NoSQL databases (MySQL, ClickHouse, Redis, MongoDB) including query optimization and schema design.
• Understanding of containerization, orchestration, infrastructure as code tools (Docker, Kubernetes, Ansible).
• Solid experience with at least one message queue/broker (Kafka, NATS, Redis Streams).
• Experience in building high-load systems with low latency.
• Experience with high frequence trading
• Strong debugging and profiling skills (pprof, flamegraphs, tracing).

Nice to Have

• Experience developing systems for Forex/CFD trading, including knowledge of:
  • Market data streams (ticks, depth, L2/L3 order books)
  • Order execution flows (market, limit, IOC/FOK, A-book/B-book routing)
  • Risk engines
  • Liquidity provider integrations
• Knowledge of efficient binary protocols: Protobuf, SBE, FlatBuffers.
• Experience with high-performance in-memory data structures.
• Familiarity with monitoring and observability: Prometheus, Grafana, OpenTelemetry.
• Understanding of FIX API integrations.
