Senior FullStack Engineer (Frontend-focused), Retail Media/AdTech Solutions (m/f/d)

About your tasks:

• Shape the future of our Retail Media platform by building end-to-end experiences across campaign management, advertiser self-service, reporting and other AdTech products.
• Build complex web applications with React, Next.js and TypeScript, including reporting, asset management, permissions, audience segments and other advertiser workflows.
• Develop backend services and integrations using Node.js and TypeScript, working with APIs, MongoDB, Redis and asynchronous workflows to support scalable product experiences.
• Own features end to end, from technical discovery and solution design through implementation, testing, rollout and production support.
• Contribute to our in-house engineering journey, helping shape the architecture and engineering practices as the Retail Media platform and organization grow.

About you:

• You bring strong commercial experience with React and TypeScript, building complex production web applications.
• You have hands-on experience with Node.js or comparable backend technologies and are comfortable designing and integrating APIs and services.
• You enjoy working across the frontend/backend boundary and taking ownership of complete product features rather than a single technical layer.
• You thrive in fast-growing product environments and enjoy collaborating closely with Product, UX and other Engineers.
• Experience with Retail Media, AdTech, e-commerce, marketplaces or B2B self-service platforms is a strong advantage, as is experience with cloud-native and distributed systems.
