(Senior) Full-Stack Developer (m/f/d)

We are looking for two Full-Stack Developers - ideally with a focus on frontend or backend - to take our avatar solution and SaaS products to the next level. You will work closely with our tech team and AI specialists, quickly understand our existing stack and take responsibility for what you deliver from day one. Independent work, technical excellence and a desire for real innovation - that is what you bring if you want to get started with us.

Your tasks

• Independently advancing our avatar solution and SaaS products
• Developing efficient algorithms for data processing and analysis
• Integrating machine learning models in collaboration with our AI specialists
• Continuously improving code quality, performance and existing systems
• Implementing and advancing our business logic based on Next.js, NestJS, TailwindCSS and Postgres, operated on modern cloud infrastructure with Kubernetes

Your profile

• Solid experience as a Full-Stack Developer, ideally with a focus on frontend or backend
• Confident use of Next.js, NestJS, TailwindCSS, PostgreSQL, REST APIs and TypeScript
• Ideally, experience with containerised cloud infrastructures (Kubernetes)
• You quickly and independently familiarise yourself with existing tech stacks
• You know common software development best practices and apply them consistently
• A strong sense of responsibility for the product components you build
• Confident use of modern tools such as Cursor
• You provide regular feedback - both professionally and interpersonally - and want to grow together
• Fluent German skills

What we offer

• Direct impact on a product that fundamentally changes digital communication - no support work, but real ownership of your product components
• Close collaboration with our AI specialists instead of working in silos - you are close to model integration, not just the surface
• Free choice between remote work and our office in Essen
• A modern, clearly defined tech stack (Next.js, NestJS, TailwindCSS, Postgres) on scalable Kubernetes infrastructure instead of accumulated legacy chaos
• A lean, fast application process: getting to know each other, competency-based interview, contract offer
• Annual salary 55.000-75.000 €, depending on experience

Sounds like you?
