Renterra is a Series A–backed SaaS company building the operating system for the $100B+ equipment rental industry. Our product handles complex, data-heavy workflows across operations, logistics, and billing — the kind of UI problems that require real design thinking and real engineering skill.

We're hiring a Design Engineer: someone who owns product design end to end and also contributes meaningfully to our React + Material UI frontend. This isn't a "designer who can inspect code" role — you'll design in your tool of choice, prototype fast, and ship real UI in our codebase.

You'll work directly with the Product Manager and a small engineering team. The role is high-ownership and high-visibility.

What You'll Do

Own end-to-end product design for core areas of our B2B SaaS product — from problem framing through shipped UI
Design and prototype rapidly, using whatever tools get you to a good answer fastest (Figma, AI tools, code, napkin sketches — we don't care)
Build and evolve our Material UI–based design system, both in Figma and in code
Contribute directly to the React frontend — not just "small tweaks," but meaningful UI work: building components, refining layouts, polishing interactions
Prototype outside the design system when exploring new ideas, then codify what works
Collaborate closely with Product and Engineering to define scope, make tradeoffs, and ship

What We're Looking For

2–5 years of experience designing and building B2B SaaS products
Strong portfolio that shows design ownership, speed, and iteration — bonus if it includes things you built, not just designed
Working proficiency in React and Material UI — you can pick up a ticket, open a PR, and ship frontend work
Strong product judgment and the ability to simplify complex workflows into clean, usable interfaces
Comfort working in a fast-moving, small-team environment where you'll wear multiple hats
Familiarity with modern design tooling, including AI-assisted workflows

Nice to Have

Experience building or maintaining a component-based design system
Experience designing for complex operational or logistics software
Background at a startup or high-growth SaaS company

Why Renterra

Competitive salary + meaningful equity at Series A
Health, dental, and vision
Flexible PTO
One of the most visible roles on the team — you'll shape what the product looks and feels like, and you'll build it yourself
A genuinely hard design problem: making dense, complex workflows feel simple
