Senior Engineering Manager, Developer Experience

About the team

The Developer Experience team owns the internal platform that every SumUp engineer touches daily: CI/CD pipelines, observability tooling, our developer portal, and an emerging AI platform. It's a high-visibility role: the work you lead directly shapes the productivity of hundreds of engineers across the company. We're looking for an experienced Engineering Manager to take full ownership of this domain, grow a team of seven engineers, and define what great developer experience looks like at SumUp as we scale.

What you'll do

• Lead and develop a growing team of 5+ highly motivated engineers across observability, CI/CD, developer portal (Backstage), and FinOps tooling — setting clear priorities and establishing strong ways of working


• Own and evolve the technical roadmap across all DevEx domains, communicating trade-offs clearly to engineering leadership and internal stakeholders


• Shape the AI Platform domain from the ground up — defining its charter and identifying where AI tooling adds real value for SumUp engineers


• Partner with product engineering managers and platform peers to drive measurable improvements in deploy frequency, onboarding time, and support load


• Build the case for how the team needs to grow, identifying skill gaps and preparing the organisation for a future where this role leads other engineering managers

You'll be great for this role if…

• You have proven experience leading platform, infrastructure, or internal tooling teams at a senior engineering manager level, with a track record of owning a technical domain end-to-end


• You bring strong technical foundation across the DevEx stack: CI/CD, observability (Prometheus, Grafana, or equivalent), Kubernetes-based platforms - sufficient to make sound architectural decisions and earn engineer trust


• You know how to lead through ambiguity and organisational change, including reorgs, scope shifts, or leadership transitions


• You can build and communicate a product-style roadmap for a platform domain, with clear prioritisation and a narrative that lands with both engineers and senior stakeholders


• You have a genuine curiosity about AI tooling in an engineering context and the confidence to lead a greenfield domain in this space

Why you should join SumUp
