Senior Platform SRE

In this role you will reinforce IG’s reliability by building and owning the platform that underpins hundreds of engineers. You will operate at the intersection of software engineering, observability, and systems reliability to turn reliability into a proactive discipline. You’ll collaborate with Platform Engineering, product teams, and Reliability Champions to define production standards and embed them as default practice. The role offers hands-on technical impact, mentorship, and opportunities to shape IG’s reliability culture and tooling.
