Software Developer - Estimating

Software Developer

We’re looking for a Software Developer to work across two key parts of our technology platform: an internal web application (.NET + Svelte) and a custom ArchiCAD add‑on (C++).

ArchiCAD add‑on

• Develop and maintain custom add‑ons using the ArchiCAD C++ API.
• Extract and process building model data (properties, parameters, geometry) for downstream tools.

Data ingestion (Python + FastAPI)

• Build and maintain a FastAPI service to handle data ingestion across the platform.

About you

• Proficiency in C++ or willingness to learn (ArchiCAD API experience is a bonus, not required).
• Proficiency in C# / .NET (ASP.NET Core, Web API, or similar).
• Relational database experience, ideally SQL Server or PostgreSQL, including query optimisation.
• A modern frontend framework — SvelteKit preferred, or React/Vue with willingness to learn Svelte.
• Solid development fundamentals: Git, debugging, testing, and CI/CD.
• Outstanding attention to detail.
• Strong analytical and problem‑solving skills.
• Self‑motivated and dedicated to ongoing improvement.
• Excellent communication and collaboration skills with a solutions‑focused mindset.
• Team player, able to build strong relationships across departments.

• Purchased leave – opportunity to apply for up to 2 weeks extra leave each year.
