Senior Software Developer C++ (f/m/d)

Introducing Thinkproject Platform

Thinkproject is a European leader in the digitalization of the construction industry, with
offices and customers spanning Europe and beyond.

Founded in 2000 — when construction project planning was still predominantly manual — Thinkproject was built on deep industry expertise and a mission to make complex
construction projects manageable. Today, we call it Construction Intelligence: software
that makes construction projects more efficient, safer, more punctual, and above
all, more sustainable.

VDC Manager is one of the flagship products in our portfolio — a complete openBIM
platform at the intersection of 3D modeling, process management, and data
intelligence.

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

VDC Manager enables the merging of diverse data and information into BIM processes,
including model checking and clash detection in 3D models, construction schedule
creation and 4D simulation, quantity and dimension determination for cost calculations, and much more. As a senior member of the engineering team, you will take ownership of complex features, drive technical decisions, and help shape the future of one of Europe's leading BIM platforms.

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

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 (OpenGL, DirectX, Vulkan, or similar)
• Knowledge of BIM concepts, workflows, and data formats (IFC, BCF) and/or experience in the AEC industry
• Experience with JavaScript (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.
