Software Engineer with AI experience, part-time 20h

Compensation: €25k – €80k • 0.0% – 5.0%

Lux Digital Solutions is hiring a software engineer with AI experience for a part-time role of 20 hours per week. The role is remote from within the European Union or on site in Luxembourg. What you will build You work on software systems that improve or automate real business workflows. You take technical responsibility for projects that go into production, from architecture and delivery to the operational handover. For systems that use AI, you define data and tool boundaries deliberately, make them visible in the architecture, document decisions and build the controls that keep critical cases reliable. Your responsibilities You build software, design technical and AI architecture and lead projects through release. You work directly with company management, with no layer in between. You translate a business goal into a robust technical solution and keep ownership when a project becomes complex. Your profile Software development is your foundation. You have built applications that others use in production, can read unfamiliar code with confidence and document technical decisions clearly. APIs, data flows, authentication, databases, integrations, containers, deployments, tests, logging, error handling, idempotency and monitoring are part of your normal work. You integrate models into robust systems, set data and tool boundaries, and test critical outcomes with reproducible cases. English is required. French, German and Luxembourgish are a plus. Conditions The role gives access to personal data belonging to our clients. It therefore requires confidentiality, strict adherence to access limits and traceability of every intervention. You must be authorised to work in the European Union. Pay is discussed at the first interview. How to apply Send your CV and a few lines about something you built that ran in production. A personal project counts as much as a professional one. Data protection Lux Digital Solutions is the controller for your application data. We process applications solely to decide on this role on the basis of Article 6(1)(b) GDPR and delete them no later than six months after the process closes, unless you explicitly consent to longer retention for future roles.
