We are looking for an experienced full-stack engineer who works primarily through AI tools and can take ownership of features end to end. You will join a German product team building business software and mobile apps for their clients. 

The working language is German: meetings, specifications and client communication are all in German.

This is not a classic "write code all day" role. Most of the implementation is done together with Claude and other AI agents. What matters is that you understand the whole system, ask the right questions, judge whether a solution is good enough, and move tasks forward independently.

What you will do
• Deliver features across backend, web frontend and mobile apps, working mainly through AI coding agents (Claude Code or similar)
• Research unfamiliar parts of the system, evaluate the existing implementation and propose what to change
• Clarify requirements directly with the German team and with the client, including business questions
• Work with databases, REST APIs and integrations with the client's ERP and third-party systems
• Spot problems on your own and resolve them
• Take tasks from ticket to release, including testing and handover

Requirements
• 5+ years of commercial software development
• Real full-stack experience: backend, web frontend and at least some mobile development
• Experience with .NET/C# or the ability to work in it confidently; Node.js, React and React Native are also relevant
• Good SQL skills and experience with REST APIs and system integrations
• Daily hands-on use of AI coding tools (Claude Code, Cursor or similar) in real projects, not only for autocomplete
• German at C1 level or higher; you must be comfortable leading a technical or business conversation in German
• Independence: you find the information you need and do not wait for detailed instructions

What we offer
• Remote work, long-term project with a German product team
• A role where AI-driven development is the standard way of working, not an experiment

We are looking for a Project Manager who will help keep the development process organized, ensure smooth collaboration across teams, and keep projects on track from planning to release.
You’ll work closely with the Product Owner, development teams, QA and design, as well as communicate daily with Dutch stakeholders.

Requirements
-1+ year of experience as a Project Manager or Delivery Manager in a software development team.
-Excellent English (C1+), both written and spoken, as you’ll communicate daily with Dutch stakeholders.
-Hands-on experience with Azure DevOps, including Boards, Sprints, Backlog, Pipelines and Test Plans.
-Ability to turn detailed product briefs and designs into clear, actionable tickets that developers can pick up without additional clarification.
-Experience with release planning and fixed deadlines. Our releases are tied to industry exhibitions, so you’ll need to manage feature freezes and fix-only periods before each event.
-Strong communication and meeting facilitation skills, including the ability to follow up with meeting summaries, action points, owners and deadlines.
-Sufficient technical literacy to communicate with engineers about APIs, backend and mobile development and identify potential risks early.

Responsibilities
-Own and maintain the backlog and sprint rhythm in Azure DevOps together with the Product Owner.
-Plan releases around industry exhibitions and ensure the scope remains realistic and achievable.
-Coordinate backend, frontend, QA and design teams, making sure dependencies are managed and no team is unnecessarily blocked.
-Keep the Product Owner proactively informed about progress, risks, decisions and blockers.
-Facilitate meetings and ensure that agreements, action points and next steps are clearly documented and followed up.
-Monitor timelines, dependencies and risks to help the team deliver releases on time.

Requirements

• 1+ year of commercial experience in software testing.

• Experience with different types of testing: functional, regression, integration, smoke, sanity, exploratory and usability testing.
• Experience in creating and maintaining test documentation, including test cases, checklists and test scenarios.
• Ability to analyze requirements, identify potential risks and define test scenarios.
• Experience with bug tracking systems and writing clear, detailed bug reports.
• Basic understanding of Agile/Scrum
