Product Engineer, C#/.NET

Role Summary

HEY THERE — WE’RE KINSHIP 👋

We’re building tools that make working with Revit simpler, faster, and a whole lot less painful. Our platform helps architects and engineers manage their content libraries, track how models evolve, and enforce better standards without the usual chaos.

We’re hiring a C# developer to help us go deeper into the world of Revit — improving our add-in, scaling sync capabilities, and crafting the behind-the-scenes magic that makes Kinship feel seamless to our users. If you know your way around Revit’s quirks and love writing clean, solid code that solves real-world problems, this is for you.

Responsibilities

• Develop and maintain our Revit add-in using C#
• Implement new features and improvements within the Revit environment
• Integrate the add-in with backend services via REST APIs
• Handle data synchronization between Revit and our cloud platform
• Contribute to architectural decisions and collaborate with other engineers on design and implementation

Requirements

• 3–6+ years of experience writing C#
• Strong hands-on experience with developing desktop application
• Solid MVVM knowledge (using CommunityToolkit.Mvvm)
• Experience with WPF or WinUI 3 (including styles, templates, and resource dictionaries)
• Confident with async programming and writing responsive, stable desktop apps

NICE-TO-HAVES

• Experience with the Revit API, or similar
• Experience with dependency injection
• Familiarity with build tools like Nuke and CI/CD pipelines
• Understanding of mapping tools (e.g., Mapperly, AutoMapper)
• You write unit tests and know when they matter
• Experience with structured logging (Serilog preferred)
• Familiarity with observability tools like OpenTelemetry
• Some experience with ASP.NET http://ASP.NET and how web APIs are built

Benefits

• Competitive salary
• A beautiful, plant-filled office in central London (by Southwark tube station) and good coffee (obviously)
• A no-BS team of people who love building great software together
• Real autonomy and influence over product and tech decisions
• A company that believes in work-life balance
