About Our Client

Our client is a global technology leader in test & measurement and secure communications, with a major engineering hub in Munich. They deliver mission-critical software solutions to highly regulated, high-stakes industries — including this role's domain, Air Traffic Control (ATC) management systems. The organisation is known for engineering rigour, technical depth, and a collaborative culture where senior engineers are given real architectural ownership.

The Role

This is a hybrid Senior Developer / Tech Lead position within a team building modern web frontend applications for ATC management software.

• Lead frontend development for a mission-critical ATC management software suite
• Drive technical conception, software architecture, and detailed design work
• Align cross-cutting target architecture with fellow architects for a consistent system landscape
• Ensure high code quality, maintainability, and long-term viability of applications
• Provide technical guidance and mentor junior developers
• Collaborate closely with backend teams to deliver integrated, high-performance solutions
• Participate actively in Scrum ceremonies (refinements, sprint planning, reviews, retrospectives)
• Continuously improve development processes, standards, and best practices

Mandatory Requirements

• Very good knowledge of TypeScript, JavaScript, and Angular
• Several years of software development experience, ideally with prior Senior Developer or Tech Lead responsibility
• Practical experience with containerisation (e.g. Docker, Kubernetes)
• CI/CD pipelines as a standard, natural part of your delivery workflow
• Strong focus on code quality — code analysis, unit testing, sustainable QA practices
• Confident communication in both German and English (written and spoken)
• Degree in Computer Science (strong grade) or equivalent demonstrable experience

Nice to Have

• Frontend test automation experience, ideally with Playwright
• Practical Scrum experience and a genuine team-player mindset with interest in mentoring
