What do you need for this opportunity

Must have skills required:

Go, Golang, PostgreSQL, AWS, ECS, EKS, Kubernetes

Vobiz AI is Looking for:

Vobiz AI is building India's most developer-friendly Voice API platform — AI-native telephony infrastructure powering 4 million calls per day. You'll join a small, high-ownership engineering team and take on day-to-day responsibility for integrating features into the platform, monitoring production alerts, and deploying microservices on AWS.

What You'll Do

• Build and maintain concurrent, high-throughput services in Go (goroutines, channels, worker pools) for call routing, dispatch, rate-limiting, and billing
• Own the data layer — write optimised SQL queries, design schemas, and manage indexes and partitioning on a large-scale PostgreSQL database (250 GB and growing)
• Monitor and respond to production alerts throughout the day using Datadog, CloudWatch, and database query analysis
• Deploy and maintain microservices on AWS ECS/EKS using Docker and container tooling; assist senior engineers with infrastructure tasks
• Integrate and harden HTTP connections with upstream services — timeouts, circuit breakers, idempotency, retry semantics
• Co-develop features in small groups, breaking down tasks and taking informal ownership of feature sprints alongside teammates
• Debug legacy Python services when needed (read and understand existing code; not expected to rewrite)
• Write unit tests and participate in code reviews
  
  

Must Haves

• 3–5 years of production Go (Golang) experience — Go must be your primary language
• Deep PostgreSQL skills: query optimisation, indexing, partitioning, schema design — at high data volume
• Experience working with large-scale datasets in production environments
• Hands-on microservices development and deployment experience
• AWS fundamentals — ECS, EKS, or Kubernetes; container tooling (Docker)
• Production debugging and observability experience — Datadog, CloudWatch, or equivalent APM tools
• Ability to read and debug Python (legacy services)
• Comfortable co-developing features in small groups and taking ownership of sprint deliverables
  
  

Good to Have

• Redis or any distributed caching service (Memcached, etc.)
• VoIP, SIP, or telephony domain knowledge (FreeSWITCH, CDRs, call routing)
• Fintech or payments-adjacent backend experience
• Reliability patterns — circuit breakers, idempotency, dedup/reconciliation, fail-open/fail-closed
• CI/CD pipeline experience — Docker builds, ECS task deployments, Terraform
