Platform Engineer - DevOps

GreyLabs AI is building the voice operating system for India's BFSI. Our Agentic Voice AI platform helps banks, insurers, NBFCs, and fintechs automate and humanise millions of customer conversations - across sales, collections, customer service, and compliance - in multiple Indian languages.

In under two years, we've scaled to 50+ enterprise clients, including RBL Bank, AU Small Finance Bank, IDFC FIRST Bank, SBI Life, ICICI Prudential Life, Motilal Oswal - processing hundreds of millions of conversations. We raised ₹85 Crores in Series A funding led by Elevation Capital with Z47, and were recognised for "Best Use of AI in Fintech" at IFTA 2025.

This is an SDE3 role on the Platform team. You will own deployment infrastructure, build the observability stack, and manage multi-cloud environments across AWS and GCP. Ownership is wide, the infrastructure you build is load-bearing, and when something breaks in production, you are the person who fixes it and closes the gap so it doesn’t break the same way again.

Infrastructure & Deployment

• Design and maintain infrastructure as code across AWS and GCP - Terraform or equivalent, versioned and reviewed like application code

• Own the CI/CD pipeline and build deployment automation 

• Manage multi-cloud cost attribution, capacity planning, and environment parity

Observability & Reliability

• Own the observability stack (SigNoz, Prometheus, Grafana) - define what gets monitored, what gets alerted on, and what gets filtered out

• Define on-call practices, maintain runbooks the team can execute under pressure, and lead postmortems that produce structural fixes

• Partner with application engineers to abstract infrastructure complexity

• 6-8 years of experience in DevOps, SRE, Platform Engineering, or Software Engineering with significant cloud operations/automation ownership.

• Has operated at least one stateful distributed system in production - Kafka, ClickHouse, Cassandra, Elasticsearch, or equivalents. 

• Experience with AWS, GCP or Azure

• Has built or significantly owned an observability stack with deliberate signal-over-noise decisions

• Writes infrastructure as code by default; treats infra changes with the same review rigour as application code

• Writes automation and tooling code fluently - Python, Go, or bash

• Has managed infrastructure in a regulated or enterprise B2B environment - IAM, network isolation, audit logging, or access control requirements that came from a compliance or security driver, not just engineering preference

• Has been on-call for a system where downtime had real consequences, and has the instincts that come from that

Not checkboxes. Signals that tell us you’re the right person.

• You’ve operated Data Engineering pipelines (Clickhouse/Debezium/Spark) - cluster tuning, materialized view debugging, slow query diagnosis at scale

• You’ve managed Distributed Systems like Kafka (or equivalent) through a real failure - broker loss, consumer group rebalancing, lag that wouldn’t clear - and can walk through exactly what happened, what you changed, and what the runbook looks like now

• Your Observability Stack has caught a production issue before a customer opened a ticket

• You’ve reduced infrastructure cost as a deliberate exercise - not a side effect - and can quantify what changed

• A hard problem in a large market. Building low-latency, multilingual Voice AI for regulated financial institutions - across diverse Indian languages and under RBI and IRDAI compliance requirements - is technically complex and commercially consequential.

• Real scale, real engineering challenges. The reliability, cost, and infrastructure challenges here reflect actual production load.

• Scope to shape the technical direction. At our current stage, architectural decisions move quickly from design to production. Senior engineers have direct influence on how the platform is built and what it becomes.

• Strong backing, proven team. Elevation Capital and Z47 are long-term partners invested in our vision. Our founders built and exited Cogno AI - they understand what it takes to build AI companies that earn enterprise trust.
