You know the difference between something that looks scalable in a diagram… and something that actually holds up when data is flying through it all day.
This is the second one.
You’ll be working on a platform sat in the middle of real-world operations — ingesting, processing and moving data continuously, across regions, with no room for guesswork when it comes to reliability or security.
It’s not greenfield. It’s not a mess either.
It’s at that stage where good engineers make a big impact — tightening things up, improving how it scales, and making sure it doesn’t fall over when it matters most.
What you’ll actually be doing
* Building Azure infrastructure properly (Terraform / Bicep — not portal clicking)
* Working across IoT Hub, Service Bus/Event Hubs, Functions, storage
* Designing systems that handle failure properly (retry, idempotency, dead-lettering)
* Running clean multi-environment setups (dev/test/prod)
* Monitoring, alerting, performance tuning — real accountability
* Implementing secure-by-design principles (RBAC, Key Vault, managed identities)
You’re not handing things off — you’re responsible for how it behaves in production.
What they’re looking for
* Infrastructure as Code (Terraform or Bicep)
* Event-driven architecture / messaging systems
* Someone who understands production systems — not just dev environments
* Solid grounding in security (access, identity, secrets, networking)
Nice to have:
* Experience in regulated / operational environments
Why this is worth it
* Systems that actually get used — constantly
* Engineering problems that don’t have obvious answers
* High ownership — you’ll feel your impact
* Plenty still to improve, not just maintain
* A platform that’s scaling, not standing still
