Job description

Senior Software Development Engineer – Spatial Modelling

Remote Role – Australia – AEST timezone

Build the engine behind how the world’s biggest retailers design their stores

We’re partnering with an innovative retail technology company on a mission to transform how physical stores are planned, optimised, and experienced.

Their platform powers global brands, combining data, 3D visualisation, and advanced spatial modelling to solve one of retail’s hardest challenges: how to design stores at scale with real-world accuracy.

What you will be doing

• Build and evolve advanced 2D and 3D spatial models that simulate real retail environments
• Model geometry, physics, constraints, and spatial relationships (e.g. product adjacency, store flow, physical fit)
• Develop systems that enable:
• Store optimisation
• Photorealistic 3D visualisation

Example challenges include:

• If products shift location, determining what should sit alongside them and why
• Simulating real shopper behaviour and physical constraints at scale

What we are looking for

Core requirements:

• Experience in computational geometry, simulation, or physics-based systems
• A mindset that balances academic depth with real-world delivery

Nice to have:

• Experience with three.js, react-three-fiber, or rapier
• Background in 3D modelling, spatial computing, or simulation-heavy environments
• Exposure to retail, CPG, or supply chain technology.
