About the role

Key responsibilities & impact

Take ownership of the IoT cloud perimeter
Get hands-on with FleetAPI, AWS Step Functions provisioning, RMS, and the Retool layer - operating 50% of the perimeter autonomously within three months, 100% within six.
Document the stack as you go. The goal isn't a wiki - it's that the team's knowledge becomes shared infrastructure, not tribal memory.
Make the cloud foundations resilient enough that scaling the fleet doesn't put pressure on a single person.
Own AWS architecture and infrastructure-as-code
Design and evolve compute (Lambda, ECS, Batch), networking, storage and IAM across the DLM perimeter.
Bring the full stack under CDK - no manual AWS console clicks to ship a critical infra change.
Make trade-offs (serverless vs container, RDS vs DynamoDB, push vs pull) and explain them to the team without dogmatism.
Drive observability and reliability
Instrument logs, metrics, alerting that ops and engineers can act on.
Run on-call rotation, write post-mortems, keep runbooks current.
Move MTTR down quarter after quarter, with the numbers to prove it.
Ship backend services
Build and maintain backend services in Node.js / TypeScript (Python where it makes sense), at production grade.
Pair with the Tech Lead and the full-stack IC on infra-aware design from the spec stage - so trade-offs are made before the code, not discovered at review.
Become the cloud referent across teams
Within 12 months, represent CIOT-DLM in cross-team architectural discussions (Platform, Data Platform, NetSec, AI).
Take ownership of one major vertical at six months - provisioning, fleet drift detection, or RMS - and ship a measurable improvement on reliability or manual correction.

Requirements

What you’ll need

4-7 years of experience in cloud engineering, DevOps or SRE - at least three of them on AWS in production, on systems that real users depended on.
You've built APIs and shipped backend services in Node.js / TypeScript (or Python). "I don't really do APIs" is a non-starter for this role.
You've handled real production incidents - and when you talk about them, you're specific: timeline, decisions, what you'd do differently.
IoT, telecom or distributed systems exposure is a plus, not a requirement. Curiosity about what happens between the cloud and the physical world is.
You can operate within a scope set by a Tech Lead and a PM. When you disagree, you know how to express your concerns clearly, route it through the right channel, and move on if your solution isn't the one adopted collectively.
