Product Engineer

We’re entering a phase of rapid product and infrastructure scaling. To support this growth, we’re hiring a Product Engineer who will work at the intersection of UX, product, and technical execution, and wants to shape how customers interact with frontier technology in materials science.

This is a hands-on, high-ownership role for someone who wants to build the core technology that enables the world’s most advanced materials to be developed and manufactured. You’ll have the freedom to make architectural decisions, work closely with scientists and engineers, and see your code directly power breakthroughs in industry and research.

This role reports directly to our and offers a significant degree of autonomy and influence over technical decisions and product direction.

Requirements

You’re a product-minded engineer who takes pride in building elegant, intuitive interfaces for complex technical systems.

You have:

• You have 3+ years of experience building modern web applications with React (or an equivalent framework) and TypeScript. If you love writing full-stack TypeScript and modelling complex state with types, this role is for you!
• Strong UX and design sensibility, with the ability to turn loose requirements into intuitive, user-friendly features.
• A desire to write reliable, maintainable, well-tested code, while being willing to rapidly prototype features when needed.
• Experience building backend APIs, and understand how to design clean, reliable interfaces. We use Node, Express, and Prisma, so experience with those (or similar frameworks) is a plus

Bonus points for:

• Experience working with data-intensive or visualisation-heavy user interfaces (D3, canvas, Three.js, WebGL, or similar).
• Familiarity with Python or scientific/engineering workflows
• Previous work in SaaS or technical B2B products

Mindset and values

• Is user-obsessed, driven to turn complex tech into intuitive, elegant experiences
• Iterates fast, values feedback, and isn’t afraid to prototype or pivot
• Balances design taste with engineering rigour
• Communicates openly and collaborates across disciplines
• Thrives in a startup environment: ambiguity, ownership, and rapid learning
