About the Role

We are looking for a Lead Golang Platform Engineer to own the stability, performance, and reliability of mission-critical backend platforms supporting real-time market data, transactions, portfolio systems, and enterprise integrations.

This is a hands-on technical leadership role focused on distributed systems, production incident management, performance optimization, and platform ownership rather than feature development alone.

Key Responsibilities

- Own production stability and act as the L3/L4 escalation point for backend and middleware systems.
- Lead root cause analysis (RCA) for production incidents, latency spikes, Kafka lag, database contention, and memory issues.
- Drive non-functional requirements (NFRs), including performance, throughput, high availability, fault tolerance, and resource efficiency.
- Design and optimize distributed systems and event-driven microservices using Golang, Kafka, PostgreSQL, and Redis .
- Ensure reliable event processing through idempotency, offset management, retries, dead-letter queues, event replay, and backpressure handling.
- Optimize PostgreSQL queries, indexing, partitioning, connection pooling, and Redis caching for high-performance workloads.
- Build configurable, rule-driven workflows and high-performance backend services.
- Improve observability through logging, tracing, metrics, Prometheus, and Grafana.
- Lead vendor knowledge transfer, take ownership of legacy codebases,



and establish backend engineering standards.
- Mentor engineers on production debugging, distributed systems, and code quality.

Required Skills & Experience
- 6–8+ years of backend engineering experience, preferably in fintech, trading, or transaction-heavy systems.
- Strong hands-on expertise in Golang , including concurrency, context propagation, runtime behavior, and memory profiling.
- Strong production experience with Apache Kafka , including consumer groups, rebalancing, offset management, and lag diagnostics.
- Proven expertise in PostgreSQL performance tuning and database optimization.
- Experience troubleshooting live production incidents and driving permanent corrective actions.
- Robust understanding of distributed systems, event-driven architecture, fault tolerance, and high-throughput APIs.
- Demonstrated ownership of non-functional requirements (NFRs), performance benchmarks, and production reliability.

Good to Have
- Experience with low-latency trading platforms, exchanges, or regulated financial systems.
- Production exposure to Kubernetes and Redis performance optimization.
- Experience with WebSockets, streaming systems, ClickHouse, and Grafana.
- Familiarity with CockroachDB or other distributed databases.
- Experience taking over vendor-built or legacy platforms.

Ideal Candidate Someone who can remain calm during critical production incidents, diagnose complex distributed-system issues, optimize runtime performance, and take end-to-end ownership of platform reliability while providing technical guidance to the backend team.
