🎯 CONTEXT 250+ local authorities already rely on Vizzia to keep their streets cleaner and safer. By the end of 2026, that number will be 450. Behind every camera in the field sits a cloud and IoT stack that has to keep up — FleetAPI, device provisioning, OpenVPN multi-shard, the routers that keep our cameras online. Doubling the fleet doesn't mean doubling the manual work behind it. It means rebuilding the foundations so it scales on its own. We're looking for the cloud and backend referent of this squad. You'll pair with Wilfried (Tech Lead) on architecture, work alongside Timon (PM) on what gets shipped, and take full ownership of the cloud foundations - so the next 200 cities we onboard reinforce what we've built, rather than stretch it thin. 🛠️WHAT YOU'LL DO 1. 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. 2. 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. 3. 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. 4. Ship backend services - Build and maintain backend services in Node.js / TypeScript (Python where it makes sense), at production grade
