DevOps Engineer - London

Location: London

Department: Site Reliability

You build infrastructure that other engineers never have to think about.

You automate the fix instead of applying it by hand twice.

You want the platform you run to power decisions involving real money.

If you have only maintained infrastructure someone else designed, this is not the role.

The Role, In Plain English

You will build and run the platform every Reflexivity squad ships on. You will join DevOps, the squad responsible for building and maintaining the infrastructure platform that powers all our microservices across multiple cloud environments.

 

This role exists to ensure our enterprise customers have a stable, reliable, and resilient platform, while making service delivery and deployments efficient, and predictable.

You will work closely with engineers across every squad to make building, deploying, and running services fast and reliable.

• After 6 months: You own pipelines or components end to end and handle incidents in your area.
• After 12 months: You own a part of the platform and are trusted to make design calls within it.
