Job Mode: Permanent Remote
Notice Period: Immediate to 30 Days Max
Role: Golang Backend Engineer (with React exposure)
Experience: 5–8 years | Allocation: ~70% Go / ~30% ReactJS | Start: Able to contribute to production within week 1 of onboarding
Salary Range : Upto 25 LPA.
1) Mandatory Requirements (Shortlist only if ALL are met)
- Experience: 5–8 years professional software development; recent, hands-on Golang in production.
- Production track record: Has built, deployed, and supported live systems (not POCs only).
- Scalable systems exposure: Event-driven microservices that run at scale (throughput/concurrency).
- Reasoning & math: Can quickly translate business rules into code (e.g., compute GST 28% on 100 ).
- Rapid ramp-up: Can ship to production within 1 week of onboarding (env setup, first ticket, release).
- Communication: Can clearly explain own architecture, trade-offs, and contribution.
- Coding quality: Smart, idiomatic Go (clean design, tests, error handling, performance awareness).
- Event-driven architecture: Kafka/SQS/SNS , idempotency, retries, dead-lettering.
- gRPC: Protobuf contracts, versioning/backward compatibility, interceptors (auth/logging).
- Data: Strong DynamoDB (modeling, partitions/GSIs/LSIs, capacity, pagination, consistency).
- Bonus if familiar with Postgres basics (ALTER, indexing, replication concepts).
- Security: OAuth 2.0, JWT flows.
- Cloud: AWS with Lambdas & serverless patterns.
2) Frontend Requirement (30% of the role)
- ReactJS ≥ 1 year hands-on.
- Comfortable re-using existing components , API integration, basic state patterns.
3) Nice-to-Haves (Plus)
- AI coding tools exposure (e.g., Copilot/Codex/Sonnet/Cursor) with responsible use —candidate has used these to accelerate 70–80% of a feature while maintaining code quality.
- Terraform & deployment knowledge (CI/CD, environment promotion).
4) Topics to Vet (Conceptual depth over theory)
- Go: concurrency (goroutines, channels, contexts), error handling, maps, testing.
- Architecture: microservices, event-driven design, data communication.
- Cloud: AWS (Lambdas, serverless), infra basics.
- Messaging: Kafka, SQS/SNS .
- Data: DynamoDB / NoSQL (also Cassandra basics), Postgres (ALTER/indexing/replication).
- Interfaces: gRPC .
- Security: OAuth 2.0, JWT .
- Code quality: “vibe coding ” = idiomatic, readable, maintainable Go.
Note: We require understanding of concepts , not just recitation.
5) Expected Interview Coverage (so agencies can pre-screen)
- Project deep-dive: Overview & architecture of current/last project; team structure ; candidate’s role/impact.
- Concurrency mini-task: Small code discussion or snippet (worker pool / fan-out-fan-in) + channel usage .
- AWS Lambdas: Where they used Lambdas, patterns for retries/backoff; how they solved issues .
- Event-driven system: Design choices (topic/queue, ordering, idempotency, DLQ).
- Data:
- DynamoDB: partition/GSI design, pagination, hot partition avoidance.
- Postgres: an ALTER example; indexing strategy; replication basics.
- Event-driven in Postgres (e.g., outbox, NOTIFY/LISTEN, CDC—at a high level).
- Performance & reliability: Troubleshoot API slowness (profiling, N+1, caching, indexes, timeouts); query slowdown approach.
- Quick reasoning checks: e.g., GST 28% on 100 ; mapping a business rule to code/data model.
6) Disqualifiers (Immediate “No”)
- Only academic/POC experience; no production deployments .
- Cannot explain own work or architecture coherently.
- Weak DynamoDB fundamentals (poor modeling; unaware of GSIs/partitions).
- Cannot write or reason about basic Go concurrency /channels .
- No experience with event-driven patterns or gRPC in practice
