.NET + Angular Senior Developer - Hybrid Lisbon (1 Day/Week)

ABOUT THE OPPORTUNITY

Join an international technology provider specializing in innovative software solutions for the public transportation sector across Europe. This offers the unique opportunity to be a technical reference and mentor for a predominantly junior development team based in Austria, while enjoying the flexibility of working from Lisbon with just one office day per week (every Monday).

You'll be working on exciting international projects that directly shape the future of public transportation systems, tackling diverse technical challenges from user interface development to complex data integration. 

The position is ideal for a senior full-stack developer who not only has strong .NET and Angular expertise but also enjoys mentoring, knowledge sharing, and technical leadership. You'll be the go-to technical authority for a growing team, influencing architectural decisions, establishing best practices, and helping junior developers grow their skills while working on meaningful software that millions of public transport users rely on daily.

PROJECT & CONTEXT

You'll be designing and developing new features and enhancements for software systems powering public transportation operations across multiple European countries. The work spans the full technical stack - from building responsive, user-friendly interfaces with Angular to implementing robust backend services with .NET/C#, and integrating complex data sources from various transportation systems.

Working with an agile, distributed team based primarily in Austria, you'll contribute actively to international projects that solve real-world challenges in the public transportation domain. The technical environment emphasizes software craftsmanship - you'll be expected to champion clean code principles, SCRUM methodologies, and professional development practices while helping junior team members adopt these same standards.

Your role goes beyond individual contribution - you'll be mentoring and influencing a junior-heavy team, helping them develop their technical skills, code review practices, and problem-solving approaches. This requires strong communication skills, patience, and the ability to explain complex technical concepts clearly. You'll work closely with customer-specific requirements, diving into analytical and conceptual challenges that require both technical depth and business understanding.
