Senior Design Engineer - Product Experience

Tacto builds AI-powered software for strategic procurement teams in manufacturing. Our product is evolving fast: we're introducing agentic capabilities that handle larger units of work autonomously - and come back to users when decisions are needed or results are ready.

That shift demands a new kind of interface. Not just new screens, but new patterns for how humans and AI agents collaborate. And those patterns need to be built, not just designed.

As a Design Engineer, you deeply understand a problem, then design, build, and ship a solution - often autonomously. You contribute directly to the codebase: building features end to end, crafting polished interactions, and ensuring that what ships feels as good as it works. You think like a designer and build like an engineer. You'll join a small design team and work embedded with engineering squads to ship product.

WHY THIS ROLE MATTERS

Engineering velocity at Tacto is high. Features move from idea to production fast - AI-assisted development is the default. That speed is a strength, but it creates a real challenge: the gap between what's designed and what's shipped keeps growing, interactions get neglected, and polish falls through the cracks.

We need someone who closes that gap by being in the code. Not a design system caretaker, but a builder who ships features with high craft - and who naturally improves the shared foundations along the way. Someone who obsesses over the details that make a product feel great: the transitions, the keyboard interactions, the edge states, the moments of delight.

YOUR IMPACT

In this role, you will:

- Design, build, and ship features autonomously - from understanding the problem, through design exploration, to production frontend code that users interact with. You own the result, not just a layer of it.

- Craft polished interactions and experiences - you obsess over the details that make a product feel exceptional: transitions, micro-interactions, keyboard behavior, res...
