Senior Backend Developer (m / w / d)

Help us revolutionize the massage industry in Germany.

At New Soul, we’re redefining modern wellness by blending premium in-studio experiences with a strong digital platform that powers booking, payments, memberships, and daily studio operations. As we scale across Germany, system stability, performance, and clean integrations are business-critical — what we ship directly affects revenue, operational load, and customer experience.

We run a lean team with high ownership, minimal meetings, and a pragmatic engineering culture : ship impact, keep things maintainable, avoid over-engineering, and document just enough so others can move fast with confidence.

Your Role

As a Senior Backend Developer, you’ll build and evolve our backend systems and integrations that support both customer-facing journeys (booking, payments, memberships) and internal operational tooling. You’ll work closely with Product, Frontend, and Ops stakeholders to deliver scalable features, improve reliability, and reduce operational friction.

This is a great fit for someone who can operate independently, handle ambiguity, and drive work end-to-end — from understanding the problem to shipping the solution and leaving the system cleaner than before.

Your Responsibilities

• Build and maintain backend services that power core platform capabilities (e.g., booking availability, memberships, payments logic, operational workflows).
• Design, implement, and evolve internal and external APIs (GraphQL / REST), ensuring consistency, performance, and long-term maintainability.
• Own technical execution for complex projects with unclear dependencies — align early, de-risk quickly, deliver steadily.
• Proactively identify bottlenecks, failure points, and technical debt; propose pragmatic fixes and execute them.
• Create proof-of-concepts (POCs) where needed to validate approaches before implementation.
• Collaborate closely with frontend engineers, product, and operations teams to ensure smooth end-to-end delivery.
