We are currently partnered with a global leader in building performance simulation software operating in the green building and low-carbon software space. This established company develops software that enables faster, easier building performance modelling, helping reduce environmental impact while maximising occupant wellbeing.

We are looking for a Senior C++ Developer to take long-term ownership of a core 3D geometry engine that sits at the heart of their software ecosystem. This is a fantastic opportunity for someone with strong C++ and graphics programming experience to lead a fundamental component of cutting-edge environmental software.

The successful candidate will be working primarily remotely with quarterly office visits. You'll be joining a small, dynamic team where developers are encouraged to specialise while also cross-training for maximum flexibility.

This role involves taking over from the current lead who is stepping down, maintaining and expanding 3D geometry handling, core architecture development, and supporting newer rendering and simulation tools. You'll also be contributing to their ongoing migration from legacy platforms to C# / .NET / WPF.

Technical Stack:

C++ (primary focus on Sketch geometry engine)
OpenGL for graphics rendering
MFC, STL, COM
C# / .NET / WPF (beneficial for migration work)
Git, XML, JSON
Jira, BitBucket (desirable)

We're looking for:

Minimum 3 years' experience in C++ development

Comfortable working with complex 3D geometry
Strong numeracy and analytical problem-solving skills
Excellent written and spoken English communication
Ability to work effectively both independently and as part of a distributed team
Flexibility to switch to urgent tasks as required
Experience with building physics and building energy modelling would be advantageous
