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 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 platfor
