About the role
Tekla Extensions Developer
Location: Harley, Ontario - on-site position
OVERVIEW
Stubbe’s is a family-owned and operated company that has been in business for over 40 years. At Stubbe’s, our continued focus is to provide unique, cost-effective, and lasting building solutions.
Stubbe’s started as a small precast company servicing the agricultural market, evolving over the past 40 years to a diversified company that provides a wide range of concrete (related) products and services.
Stubbe’s is known for its forward-thinking solutions, quality and customer service and offers significant experience and expertise in providing optimal solutions for commercial, industrial, residential, and agricultural structures.
We are seeking a Tekla Extensions Developer to build extensions: components, C# plugins, macros, and utilities for Tekla Structures that standardize modeling, accelerate drawing production, and deliver accurate data to Trimble Connect, ERP, and production systems. We welcome strong C# developers from adjacent CAD/BIM ecosystems; Tekla experience is a strong plus but not required—training and mentorship will be provided.
This is a full-time, on-site position requiring effective collaboration with modelers/detailers, project managers, and software development teams.
THE DAY TO DAY
- Design and build custom tools for Tekla using C# (plugins with user-friendly dialogs, macros, utilities).
- Create drawing automations: templates/cloning, rule libraries, filters, dimensioning and view setup, and batch publishing.
- Standardize UDAs/property sets, naming conventions, Organizer/Task Manager setups, and implement data validation rules.
- Develop model health checks and fix tools (geometry/class/profile checks, assembly completeness, statuses).
- Build and maintain exports/integrations for ERP and production (e.g., CSV/JSON/XML, Unitechnik, BVBS, PXML, DXF, IFC) and Trimble Connect sync.
- Collaborate with the developers, detailers, and project managers to capture requirements, prototype, test, and roll out improvements.
- Maintain source control, code reviews, and CI builds; document tools and train users.
- Support Tekla environment upgrades and extension management; troubleshoot performance and data quality issues.
- Monitor adoption, gather feedback, and iterate to improve speed, reliability, and usability.
WHAT WE ARE LOOKING FOR
- Bachelor’s degree in computer science, Engineering, or equivalent experience.
- 3+ years professional C#/.NET development, including building desktop tools or plugins.
- UI development experience (WPF preferred; WinForms acceptable); familiarity with MVVM is an asset.
- Experience automating or extending at least one 3D/CAD/BIM platform (e.g., Revit, AutoCAD, Inventor/SolidWorks, or similar).
- Solid understanding of BIM concepts and model-to-drawing workflows (properties/UDAs, assemblies, naming conventions).
- Source control (Git) and modern development practices (code reviews, unit testing, CI/CD basics).
- Strong problem-solving and ability to translate user workflows into reliable tools; clear documentation and communication.
