Senior Principal Platform Lead || AI & Agentic Systems

We have a platform that can do more than our developers are getting out of it. The gap isn’t capability, it’s the experience. Too much tribal knowledge, too many tickets to get things done, too much cognitive load between “I want to build something” and “it’s running in production.”

As Senior Principal Platform Lead, Platform DX, you close that gap. You will set the strategy, own the Internal Developer Platform, define golden paths, and drive adoption across NGA and IFS product teams, serving as the voice of the developer inside the platform organisation. You combine architectural thinking with hands-on delivery, and you understand that the best developer platforms are the ones developers actually want to use. This is not a management role, but you will lead without authority across a large, distributed engineering organisation.

• Own the IDP vision, roadmap, and end-to-end execution at IFS, service catalogue, self-service scaffolding, golden paths, CI/CD integration, and developer portals
• Own the developer experience vision for the Nexus platform, from service creation through to production observability
• Work across Kairos, Nexus, Auth, Base Tech, and product teams to deliver cohesive, integrated developer experiences
• Define platform standards that make the right way the easy way, not mandated, just obviously better
• Drive measurable adoption: onboarding time, self-service completion rates, platform NPS, time-to-first-deployment, DORA metrics
• Integrate authentication and authorisation services into the IDP self-service model
• Work directly with NGA product teams and IFS R&D; domain teams to understand where they’re struggling and prioritise what to fix
• Partner with IAM, infrastructure, and SRE teams to ensure the developer-facing surface of the platform is coherent, reliable, and secure
• Establish feedback loops, developer surveys, usage analytics, office hours, and act on them relentlessly
• Influence platform strategy at the architectural level and represent the developer platform in technical leadership forums
• Mentor and technically guide Principal and Senior platform engineers, raising the bar on what “good DX” looks like at IFS
