Software Engineer - Golang

Recro; Bengaluru; On-site; INR 1,200,000 - 2,400,000; Full time

Job summary

Recro in Bengaluru, India is hiring a backend engineer to lead Go-based migrations and microservices. You will redesign Python services in Go, build migration harnesses, and ensure data consistency across schema migrations. The role emphasizes Go concurrency, MySQL/PostgreSQL query tuning, and Kafka messaging.

Familiarity with Redis, Docker, and Git is valued. This is a full-time on-site position. You will work with shadow traffic, feature flags, and rollback testing to ensure safe deployments

Qualifications

• 3+ years of backend development experience.
• Strong hands-on experience with Golang.
• Deep understanding of concurrency and goroutines.
• Experience with PostgreSQL and/or MySQL.
• Familiarity with Redis and caching mechanisms.
• Experience in designing and building microservices.
• Strong problem-solving and debugging skills.
• Experience with Docker and Git.

Responsibilities

• Own the PythonGo migration of designated services; read and fully understand the Python, then redesign idiomatically in Go rather than transliterating.
• Build the migration harness: shadow traffic, response diffing, metric parity dashboards, feature-flagged rollout, tested rollback.
• Own the schema-to-schema migration; mapping, backfill, dual-write and reconciliation, consistency verification, documented cutover and rollback point.
• Build Go services — HTTP APIs, background workers, stream consumers.
• Use Go concurrency deliberately: goroutines, channels, context propagation, worker pools, graceful shutdown, leak prevention.
• Own MySQL schema and query performance from Go; pool tuning, transaction scope, live-table migrations.
• Build Kafka producers and consumers with correct partitioning, offsets, replay and DLQ handling.
