Role

Senior Full Stack Software Developer (m/f/x) – TypeScript · React · Node.js · PHP · Azure

The Challenge

You will be the primary developer responsible for our Azure‑based Web Portal (CMS + user management), a Craft CMS online shop and a custom WordPress marketplace. This is a hands‑on role: you design, build, deploy and maintain — with full end‑to‑end ownership.

Day-to-Day Responsibilities

• Build and maintain the custom web portal (CMS) across frontend, backend and APIs (React UI, Node.js/Express services).
• Develop and evolve the PostgreSQL data model and integrations using Prisma ORM.
• Design and evolve RESTful APIs used by web and mobile clients.
• Extend and maintain the Craft CMS online shop (features, content structures, templates, integrations), a custom WordPress marketplace (custom codebase, minimal plugins, ACF for content modeling) and maintain integration with Stripe.
• Manage the integration between the custom web portal (CMS) and Craft CMS for user management, ensuring consistent synchronisation via webhooks and APIs.
• Drive architecture improvements, refactoring and code quality.
• Ensure stable deployments and production operations across Azure and Hetzner/Ploi infrastructures.
• Improve reliability, performance, monitoring and security of services running in Azure Cloud.
• Document decisions and keep systems understandable for future maintainers.
• Troubleshoot production issues end‑to‑end and drive fixes.

Your Profile

• 5+ years of full stack development experience.
• Deep expertise in TypeScript/JavaScript: React, Node.js/Express, RESTful APIs.

• CI/CD experience: GitHub Actions, Azure provisioning and monitoring.
• WordPress (custom plugins/themes, ACF) and Craft CMS experience.
• Authentication/SSO via OIDC/OAuth 2.0 and payment integrations (Stripe).
