ROLE SUMMARY
Are you a hands-on engineer who raises the bar for everyone around you?
Join us at FTSE Russell We're establishing a team of engineers passionate about software craftsmanship, quality, and substantial impact. As a Lead Software Engineer, you'll own the technical direction of the software that powers the indices trusted by financial institutions worldwide.
We build primarily in Python, so that's our preference — but depth of engineering judgement matters more to us than the language on your CV. If you've led the design and delivery of responsible systems in Java, C#, C, C++, Scala, Go, or Rust and you're motivated to lead in Python, we'd like to talk. At this level we expect you to become fluent quickly and to bring the cross-language perspective with you.
This is a hands-on Lead IC role — not a management role. You'll still be writing and reviewing code every week. What changes at this level is scope: you own architecture and technical direction in a defined area, you mentor and grow the engineers around you, and you raise quality across the team through reuse, good design,



and hands-on support. The systems handle serious volumes of financial data, so there's real depth in the data problems — but you're being hired as a software engineer who leads through code.
If you're excited about building systems that matter and making the engineers around you better, we'd love to meet you.
WHAT YOU'LL BE DOING
We're building the next-generation index data platform at FTSE Russell — and we want you to shape it with us:
- Staying hands-on — designing and writing production code, primarily in Python with 10 +yrs of experience , and setting the standard for what good looks like through the code you ship
- Owning technical direction and architecture for a defined area of the platform, and making the trade-offs explicit so the team can move fast with confidence
- Leading design of software systems — services, APIs, shared libraries, and the interfaces between them — with re
