Xplanis AG is a leading software provider in the logistics and transportation sector. Our Transport Management System (TMS) X4fleet is a scalable, cutting-edge software platform that forms the digital backbone for many transport operators. As the official partner for the Swiss Road Transport Association ASTAG, Xplanis supports the federal diploma for dispatchers with its X4fleet platform, making it a household name in Switzerland.
To support our continued growth, we are looking for an experienced Senior Full Stack Developer to join our development team in Bern. You will play a key role in designing, developing, and enhancing our Transport Management System. Our platform is continuously evolving — we strive to improve both technology and functionality to remain at the forefront of innovation and reliability. You'll work in a bilingual (English/German) environment, collaborating closely with a motivated team focused on delivering a high-quality, scalable software product to our customers.
Responsibilities
- Take ownership of the full software development lifecycle — from analyzing requirements and designing architecture to development, testing, and maintenance.
- Design, develop, and optimize scalable software solutions and APIs using C#, .NET Core, ASP.NET MVC, and JavaScript.
- Collaborate with cross-functional teams (QA, DevOps, Product Management) to enhance existing applications and build new functionality.
- Produce high-quality, maintainable code following best practices, patterns, and standards.
- Troubleshoot and resolve software defects through root cause analysis and performance optimization.
- Oversee and refactor existing codebases to improve performance, reliability, and maintainability.
- Contribute to system architecture and play a key role in defining future technical direction.
- Manage and version source code using Git and modern branching strategies.
- Support and enhance CI/CD pipelines in Azure DevOps, including automated testing and security integration.
- Mentor junior developers and promote best engineering practices within the team.
Requirements
- 7+ years of professional experience in .NET-based software development.
- University degree in computer sciences/engineering or related field
- Strong expertise in .NET Framework and .NET Core, with proven architectural design skills.
- Proficient in back-end development with C#, REST APIs, and database-driven applications.
- Experience with SQL Server and/or PostgreSQL (database design and optimization).
- Working knowledge of front-end technologies (HTML, CSS, JavaScript), while modern frameworks (e.g., Angular, React, or Vue) are beneficial but not mandatory
- Familiarity with DevOps tools and practices, including Docker, CI/CD, and Kubernetes.
- Hands-on experience with Azure App Services, Functions, and cloud architectures.
- Strong analytical and problem-solving skills, with attention to code quality and performance.
- Proven ability to lead and inspire teams toward achieving strategic goals. Fluent in English and German.
We Offer
- A key role in a fast-evolving product used across multiple European markets.
- Opportunity to influence architecture and technical direction.
- Flexible working conditions and hybrid setup (office in Bern).
- A collaborative, international team culture that values initiative and clarity.
- Competitive compensation package.
