Senior DevOps Engineer

Oritain is the global leader in product origin verification, with locations in Auckland, Dunedin, London, Singapore and Washington D.C.

We sit at the intersection of forensic science and supply chain technology, harnessing science and data to verify the genuine origin of materials across the world's most critical commodities. Our mission is to protect people and the planet by ensuring transparency and integrity in global supply chains.

As we scale our engineering platform to match our growing ambitions, we are seeking a Senior DevOps Engineer to join our engineering team in London and take ownership of the cloud infrastructure that underpins everything we build.

About the Role

The Senior DevOps Engineer plays a critical role at Oritain, responsible for building, automating and securing the Microsoft Azure cloud platform that hosts all our mission-critical software and services. This is a strategic blend of infrastructure architecture, security implementation and developer enablement, working closely with the Engineering Manager and development squads to own the delivery, operational health and continuous improvement of our cloud platform.

Reporting to the Engineering Manager, you will be the person our engineers rely on to ship confidently and operate reliably. You will bring deep hands-on expertise across Terraform, Azure, C#, Python, DevOps and Docker, and you will use that expertise to raise the bar across the platform, making it faster, safer and easier to build on.

For a DevOps engineer who wants real ownership, technically interesting infrastructure challenges and the chance to work on a platform with genuine real-world impact, this is a compelling opportunity.
