We are searching for forward-thinkers who are eager to challenge themselves and make a tangible impact. If you are passionate about creating sustainable and intelligent transport solutions, we want you on our team.

Providing engineering lifecycle evidence to support safety cases, assurance activities, and independent assessment

Providing portfolio-level leadership across engineering delivery teams to enable predictable, controlled releases into operational environments and improve consistency of tooling adoption across programmes

Driving Engineering DevOps maturity through a prioritised roadmap that balances operational need, portfolio risk, assurance requirements and long-term business value

What you’ll need to succeed..

Experience in (non-software centric) DevOps or systems/tooling engineering roles within rail and transportation, supporting engineering delivery

CI/CD tooling with controlled release and approval mechanisms

Management of tooling in an IEC 62443 / NIS2 compliant environment

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
