• Keeping production benches running smoothly, and helping out on small prototype setups.
• Working hands-on with electrical schematics and basic electrotechnical tasks.
• Using tools like Python, Git and the NI tool suite — plus maybe some C#, LabVIEW or similar, according to the need and you what you see makes more sense.
• Making sure everything meets railway and electrical standards.
• Keeping your work well organized with proper version control.

Requirements

• You’re proactive and enjoy finding solutions, not just problems.
• You like working in a team where everyone supports each other.
