Introducing Thinkproject Platform

• Today, we call it
• Construction

Intelligence: software that makes construction projects more efficient, safer, more punctual, and above all, more sustainable.

About the Role

We are looking for a Senior C++ Software Developer to join the team behind VDC Manager — Thinkproject's complete open BIM software, developed by industry experts and trusted by AEC professionals worldwide.

What You Will Do

• Core Development
• Architect, design, develop, and test new and existing features within VDC Manager
• Write clean, well-structured, secure, and testable modern C++ code (C++17/20)
• Take ownership of complex technical areas — from geometry processing and 3D rendering to data exchange and cloud connectivity
• Troubleshoot, debug, and upgrade existing systems with a focus on performance, scalability, and reliability
• Technical Leadership
• Drive technical analysis and research, including evaluation and selection of technical approaches and third-party components
• Define and enforce best practices within the development team (code reviews, CI/CD, testing standards, architecture patterns)
• Contribute to architectural decisions and provide technical guidance across the team
• Mentor and support mid-level and junior developers
• Collaboration & Communication
• Collaborate closely with Product Owners, UX designers, and BIM domain experts to translate requirements into robust technical solutions
• Demonstrate and present technical work to product owners and stakeholders in a clear and structured manner
• Work as part of a distributed, international team — contributing to technical discussions on implementation approaches and user interfaces
• Continuously learn and apply modern tools, frameworks, and engineering processes
• What you need to fulfill the role
• Must-Have
• 6–8 years of professional software development experience
• Expert-level knowledge of C/C++, including modern standards (C++14/17/20)
• Strong skills in software architecture, data structures, and design patterns
• Excellent problem-solving and analytical skills — able to diagnose and resolve complex technical issues
• Solid understanding of CI/CD pipelines, software quality practices (performance, scalability, security, testability)
• Fluency in English (written and spoken) — our working language across the engineering team
• Strong Advantages
• Experience with Qt for desktop application development
• Hands-on experience with graphics programming (Open GL, Direct X, Vulkan, or similar)
• Knowledge of BIM concepts, workflows, and data formats (IFC, BCF) and/or experience in the AEC industry
• Experience with Java Script (user scripts), Python (utilities and build tooling), or C# (plug-in development and web services for Thinkproject cloud connectivity)
• Familiarity with web services and REST APIs for cloud platform integration
• German language skills are a plus but not required
• Code Sample (Required)

As part of your application, please share a C/C++ code sample — a function, class, or module that you wrote yourself and are proud of, or that best represents your coding style and preferences.

• It does not need to be executable or a complete program
• It can come from a personal project or a previous role (anonymization is perfectly fine)
• You are welcome to supplement it with screenshots, videos, papers, or prototypes — anything that helps showcase your work and engineering thinking
• This is not a test — it is an opportunity to show us how you think and how you write code.

What we offer

• Lunch 'n' Learn Sessions
• Women's Network
• LGBTQIA+ Network
• Coffee Chat Roulette
• Free English Lessons
