Job Title
Senior Platform SRE
Job Description
IG is a FTSE 100 fintech operating across five continents, serving over 1.3m customers and handling billions of dollars in transactions – built on scale, trust, and proof. We didn't pivot to innovation; it's how we've always operated . What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that's rare in established businesses.
The bar is high – bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next. Join us at IG – the future gets built here.
The Platform SRE team is the engine of IG’s reliability programme. We sit within Infrastructure & Operations, working across IG’s hybrid estate of on-premises HashiCorp Nomad and AWS.
We are not a reactive ops team. We build the platform, standards, and tooling that make reliability the default for every engineering team at IG. Through the SRE Guild, we connect with Domain SREs and Reliability Champions across the organisation, setting the bar and lifting it together.
You will be a hands-on technical contributor at the heart of the Platform SRE team, owning pieces of the reliability platform that hundreds of engineers depend on. You will work at the intersection of software engineering, observability, and systems reliability, turning reliability from a reactive concern into a proactive engineering discipline.
You will partner with Platform Engineering, product teams, and Reliability Champions to define what good looks like in production and then make it the default. You will contribute to the SRE Guild, mentor engineers across the organisation, and when things go wrong, you will be on the call helping to mitigate, understand, and prevent a repeat.
