Design Engineer

About the Role

The AI boom depends on data centers coming online and staying online. At Entangl, we’re building the AI operating layer that helps make that happen. Our platform connects engineering knowledge, equipment data, and live telemetry so teams can catch problems before they become outages. Bringing these facilities online and keeping them running is one of the defining challenges of the AI era. Our ambition is to become the operating layer for the world’s most critical infrastructure.

As a Design Engineer, you are someone who:

• Sees a feature request and thinks "this could be a cathedral."
• Has cried, at least once, at a really well-made hover state.
• Believes the difference between good and great is twelve pixels and a week of your life.

This is a design role first. You’ll own the UX and UI of the product end to end, from research and flows to visual design, motion, and production code in front of operators at live sites. You’ll work directly with the founders, engineers, and customers, and shape how some of the most critical work in the AI economy gets done.

We're seeking someone who can redraw an entire product surface on Tuesday, prototype it in Svelte by Wednesday night, and ship it to real data center operators by Friday. Someone who thinks "enterprise software" is an insult, not a genre. Who looks at the tools teams have been stuck with for 20 years and gets genuinely angry about it.

What you will do

• Own the UX of core product surfaces: AI-generated procedures, step-by-step execution, interactive electrical one-line diagrams, equipment catalogs, and maintenance planning. Map the flows, talk to operators, and decide what the product should do before deciding how it looks.
• Design the UI: typography, layout, information hierarchy, and interaction for dense, high-stakes information, so it reads as calm, fast, and hard to misread.
• Own and grow the design system: tokens, components, patterns, and documentation, kept in sync between Figma and code so the product feels like one coherent tool.
• Design motion and interaction: transitions, micro-interactions, and feedback that help people understand what changed and where they are, prototyped and then built for real.
• Prototype in code, put it in front of real users, and ship in days, not quarters.
• Hold a high bar on the details: empty and loading states, accessibility, performance, and localization (we ship in six languages).
• Bring customer feedback straight into the product, working alongside the people who use it.

You may be a strong fit if

• You have 3+ years of UX/UI design for software products, and a portfolio that shows both the thinking (flows, research, trade-offs) and the craft (shipped UI).
• You have strong taste in typography, layout, and interaction, and the judgment to remove a feature rather than hide it behind a menu.
• You have built or maintained a design system: tokens, component libraries, variants, and the rules that keep them consistent.
• You design motion with purpose and can build it: CSS transitions and keyframes, the View Transitions API, or framework animation tools, with attention to timing, easing, and reduced-motion preferences.
• You are fluent in Figma (components, variables, auto layout, prototyping) and you prototype in code, not only in Figma.
• You write production-quality TypeScript, HTML, and CSS, and know a modern component framework well. Svelte is ideal; strong React or Vue experience and a willingness to learn Svelte also works.
• You are comfortable with ambiguity and short feedback loops.
• You have designed complex, data-heavy tools. B2B, industrial, or mission-critical software is a plus.
• You are curious about the physical world: power, cooling, and how buildings actually work.

This role is probably not for you if

• You want to hand off mockups and have someone else build them.
• You need a detailed spec before you start.
• You would rather polish one screen for weeks than ship and iterate with users.
• You think enterprise software is supposed to look like enterprise software.

Why join Entangl

Small team. Outsized influence. Ownership of the whole product experience. Work that ships to live facilities, not a backlog. Design that shapes the infrastructure behind AI. Meaningful equity for everyone on the team. Entangl is backed by Y Combinator and leaders from Nvidia, Cloudflare, AMD, Hugging Face, and others.

Tools and stack

• Design: Figma (components, variables, prototyping), our own design system with tokens and a shared component library.
• Motion: CSS transitions and keyframes, the View Transitions API, Svelte transitions and animations.
• Build: Svelte 5, TypeScript, Vite, Storybook, Supabase/Postgres.
