Software engineer jobs in Germany

About the role

You'll own the integration backbone of our client projects: the RESTful APIs, webhooks, and middleware that connect HubSpot, ERP systems, data warehouses, and the long tail of third-party platforms our clients run. Today this work is squeezed between Senior and Principal engineers who are committed to delivery and AI initiatives. You free that bottleneck. You'll ship production code, write the OpenAPI specs that go with it, build a reusable integration pattern library, and advise client teams on integration architecture decisions. The bar is zero critical integration failures in your first 12 months.

What you'll bring

• 2 to 4 years of professional software engineering experience, with hands-on integration work as a meaningful part of the role
• Productive in at least one of Node.js, Python, .NET, or Java, with the ability to read and debug code in a second language
• Direct experience designing RESTful APIs and selecting integration patterns (webhook, polling, event-driven, middleware), with concrete examples of trade-offs you've made
• Treats OpenAPI/Swagger documentation as part of delivery, not as an afterthought
• Has shipped to production via CI/CD pipelines (not local builds or manual deployment)
• Comfortable translating technical integration constraints into plain language for non-technical PMs or client contacts
• Pattern of problem ownership: investigates, proposes, flags with context, rather than escalating "I'm stuck"
• Willing and able to work on-site in Böblingen at minimum 2 days per week
