Role Summary
We are building and stabilizing mission-critical trading and capital markets platforms handling
real-time market data, transactions, portfolio systems, and enterprise integrations.
We are looking for a Lead Golang Platform Engineer who will act as:
Stabilization anchor
NFR owner
Distributed systems authority
Production escalation point
Architecture guardrail for the backend team
This role is not feature-driven.
It is about production reliability, performance engineering, and platform ownership.
Core Responsibilities

1. Platform Stabilization & Production Ownership Act as L3/L4 escalation for backend/middleware systems Lead root cause analysis (RCA) for production incidents Diagnose latency spikes, Kafka consumer lag, DB contention, memory pressure Reduce firefighting by fixing systemic issues Own post-incident hardening
2. Non-Functional Requirements (NFR) Ownership Own and enforce: Performance benchmarks Throughput targets High availability standards Fault tolerance & graceful degradation Backpressure handling Resource efficiency Identify and eliminate risks in: Latency GC pauses Lock contention Message ordering issues Retry storms
3. Distributed Systems & Event Architecture Design and stabilize systems built on: Golang PostgreSQL Kafka Redis Ensure correctness in: Consumer group balancing Offset management Idempotency design Retry strategies Dead-letter handling Event replay Backpressure management Architect and optimize: Event-driven microservices High-throughput APIs Concurrent workflows
4. Advanced Data & Real-Time Systems Optimize SQL query performance under load Improve indexing, partitioning, connection pooling Design Redis caching strategies for low latency Work with OLAP systems (ClickHouse + Grafana) Optional exposure to distributed databases (CockroachDB)

7. Vendor Transition & Codebase Ownership Lead structured knowledge transfer from external vendors Take ownership of legacy codebases without destabilizing production Identify high-risk components and stabilize incrementally Establish backend engineering standards
8. Team Enablement Mentor 3–5 year engineers Teach production debugging Guide distributed systems thinking Raise code quality standards Act as technical anchor (not people manager initially) Required Experience 6–8+ years backend engineering Strong production experience in fintech / trading / transaction-heavy systems Deep expertise in Golang: o Concurrency patterns o Context propagation o Runtime behavior o Memory profiling Strong Kafka production knowledge: o Consumer groups o Rebalancing o Offset handling o Lag diagnostics Strong PostgreSQL performance tuning experience Experience handling real production incidents in live systems Proven NFR ownership Strongly Preferred Experience in low-latency trading environments Kubernetes production exposure Redis performance optimization WebSockets / streaming systems Exchange-integrated or regulated systems Vendor-built system takeover experience Who This Role Is For This role is for someone who: Stays calm during production incidents Thinks in distributed systems, not endpoints Can read messy legacy code and stabilize it Understands performance at runtime level Wants to own platform reliability If you want to only build features, this role is not for you. If you want to own the stability of capital markets infrastructure, it is.
