EOI - Design Engineer

About Atomic Tessellator

Atomic Tessellator is the computational infrastructure for advanced materials, enabling defence and aerospace organisations to rapidly model, test, and optimise materials under extreme constraints.

Our mission is to remove the materials bottleneck so civilisation can advance at the speed of compute.

We’re a seed-stage company with a headcount of five, and have been around for a little over a year. In this time, we have:

• Built a distributed worker architecture to modularise computational materials science operations.
• Scaled machine-learned interatomic potential (MLIP) models to enable multi-GPU inference, letting us model up to 700,000 atoms
• Completed pilot projects across aerospace, defence, nuclear fusion, and advanced polymers.
• Discovered (and are in the process of patenting) two materials, one of which is a high-temperature rare earth magnet substitute.

Everything modern depends on advanced materials, but materials development remains slow, expensive, and heavily constrained by physical trial and error. Atomic Tessellator is building a CAD-style simulation engine for materials discovery: computational infrastructure that lets organisations design, model, test, and optimise materials before committing to costly real-world experimentation. We're building a validated predictive engine and deploying it as secure infrastructure for teams that need reliable answers under real operational constraints. Materials resilience underpins industrial sovereignty and defence readiness. The organisations that can model and deploy advanced materials fastest will shape the next generation of strategic capability.

About the role

We're seeking expressions of interest for a potential Design Engineer role at Atomic Tessellator. Computational materials science has historically been an academic discipline where design and user experience were secondary concerns. The field is synonymous with terminal interfaces, Fortran scripts, and dense PDF documentation. We believe there's an opportunity to bring genuine craft and intentionality to how researchers interact with simulation tools.

This role encompasses two dimensions: 3D/WebGL performance and visual interaction design. This is the kind of role where you'll exercise your creative freedom, and spend 80% of your time working on the last 20%.
