• You shape the technical future • You take technical ownership for your area — from architecture to production operation. • You define target architectures, make well-founded architecture and build-vs-buy decisions, and set clear technical guardrails for our modern Java/Spring Boot and Angular/TypeScript landscape. • You question existing solutions, monitor market and technology trends, and deliberately evolve our systems with the ambition to actively shape the market rather than follow it. • You connect product and engineering • You work closely with Product and stakeholders and translate business goals into actionable technical approaches. • You critically scrutinize requirements, make dependencies and risks transparent, and support informed decision-making. • You evaluate AI potential and integrate it deliberately where it creates real added value — whether in the development process or in the product. • You keep delivery, quality and costs in view • You are responsible for the technical perspective across Discovery & Delivery, focusing on architecture, quality and cost/benefit trade-offs. • You avoid unnecessary complexity and make clear decisions about where innovation makes sense. • You think about engineering through to operations • You maintain our high code and quality standards and ensure we can continue to release quickly and reliably. • You think beyond the merge request, detect structural weaknesses early, and ensure stability, maintainability and transparency in production. • You provide technical guidance • You work with experienced developers who operate autonomously and discuss on equal footing. • Through sparring, feedback and shared guardrails you support them in taking responsibility and making confident technical decisions. • You are a strong communicator • You excel with open, clear and inspiring leadership — particularly during periods of change.
