Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Full-Stack Engineer - **Company:** Trenkwalder Personaldienste GmbH - **Location:** Düsseldorf, Germany - **Salary:** €60,000.0 - €100,000.0 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Amazon Web Services, Automation of Tests, Cloud Engineering, Databases, Distributed Systems, Github, Next.js, Software Engineering, Large Language Models, Asynchronous Programming, Microservices - **Published:** September 9, 2026 - **Apply:** https://www.careerjet.de/jobad/ded335a0d0eebbafb96a07bb422b8c53e0 ## About the Role * Experience with agentic software development and genuine interest in LLMs - you know how to integrate them productively into tooling and handle the quirks of generative models pragmatically * A solid grasp of cloud architecture (ideally AWS and GCP) and a feel for what high performance, data-intensive systems really need * A solid testing mindset - automated testing is second nature to you, not an afterthought * Analytical thinking and a genuine hands-on mentality: you don't just talk about architecture, you build it * A strong sense of ownership - you want to see your topic through, not just tick off your part of the ticket * No specific degree required - what matters to us is what you can do and live, not what's on your transcript ## Description Our focus is on qualified professionals-the backbone of the European economy-and on the consistent integration of modern technologies. Our mission is to fulfill the European promise of free, cross-border work. Our success is based on long-standing customer relationships, trust, and quality, as well as on continuous development through innovative technologies. Full-Stack Engineer (m/f/d) Ihre Aufgaben You don't want to build "just another Next.js app" - you want to understand how software really works. How distributed systems communicate cleanly across microservices, how databases are put to work so they stay stable under real load, and how LLMs become a solid part of the engineering pipeline instead of a gimmick. If that's you, keep reading. We build TalentAI - a platform that rethinks recruiting, with AI as a genuine part of the product, not a feature sticker. For us, Agentic First isn't a slogan: we believe LLM-powered, agentic workflows are fundamentally changing how software gets built - and we want to help shape that, not just watch it happen. We don't just build bleeding-edge technology, we work with it ourselves every day. If that excites you as much as it excites us, you're in the right place. * You own your feature end to end - from planning through coding and testing to running it in production - working closely with our interdisciplinary teams * You work on distributed systems with a microservice architecture and asynchronous communication between services * You integrate LLMs as a productive part of our tooling and processes, handle their non-deterministic behavior with confidence - and help push forward what agentic software should be able to do next * You build on AWS, deploy and operate your services, and rely on automated tests instead of gut feeling * Your code lives in GitHub, with clear processes instead of chaos * You work in an international, diverse team - we're active in 15 countries, and we're proud of it, * Flexible working hours and hybrid working models (Focused on the Düsseldorf area. No rigid on-site requirement - but we like meeting regularly in the office; a hybrid model with a fair share of in-person time is lived practice for us, not a rigid mandate) * A professional, collegial environment with flat hierarchies * Continuous professional and personal development ## Related Videos - [Beyond Hiring: Building a Sustainable Talent Acquisition Engine at Deutsche Bahn](https://www.wearedevelopers.com/videos/1856-beyond-hiring-building-a-sustainable-talent-acquisition-engine-at-deutsche-bahn) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Kubernetes and Microservices with Multi-Model Databases](https://www.wearedevelopers.com/videos/382-kubernetes-and-microservices-with-multi-model-databases) - [Robots are coming into the wild!
