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

We are on a mission to turn the world of grilling upside down. At KOQOON, we build intelligent grill systems that combine cutting-edge Bluetooth and Wi-Fi technology with extraordinary design and culinary ambition — and we are just getting started.

To take our digital platforms to the next level, we are looking for a Senior Full Stack Software Developer who is as passionate about clean, maintainable code as we are about reinventing an entire product category. You will join a small, driven team where every contribution counts and where you can help define how we build — not just what we build.

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.
• PostgreSQL and ORM experience (Prisma preferred).
• Strong CSS/UI skills — MUI and Tailwind CSS experience welcome.
• Solid testing habits: Jest (required), Playwright (nice to have).
• 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).
• Fluent English — German is a bonus, not a requirement.
  
  

What Makes Us Different

We are a start-up with something most start-ups do not have: the stability and resources of an established family business behind us. That means you get real ownership and room to shape things — without the chaos. Here is what you can expect:

• Meaningful work on a product that is genuinely changing a market.
• Hybrid working model with flexibility that fits your life.
• Competitive compensation according to KV Handel.
• A close-knit team where your ideas are heard and your contributions are visible.
• The opportunity to grow into a key role as we expand internationally.
