Design Engineer

The Opportunity

We're looking for a Design Engineer to own the core Restate UI, design and code.

Our UI is where developers end up when something is running, stuck, or has already gone wrong. It's a live window onto a distributed system that keeps moving while you're looking at it. The data is large, it changes under you, and the person reading it is usually in a hurry.

Developers already like Restate for making something technically complex feel simple. Holding that as the product grows is the job, and you'd hold it end to end: the design decisions and the code that ships them.

Durable runtimes are becoming the next foundational infrastructure layer, especially for AI. Restate’s vision is to make durable execution efficient and lightweight to run.

Restate is built by a team of world-class engineers - the creators of Apache Flink, leaders from Meta's messaging infrastructure, and senior engineers from AWS and Confluent.

AI-native companies like Replit as well as Fortune 500 enterprises rely on Restate in production for their core applications.

With a fresh $20M Series A fundraise by top tier investors and strong traction, we’re just getting started and are looking for people who share our vision and work ethos.

We want to hire a great Design Engineer to ensure a stellar developer experience across the core Restate UI and adjacent parts of the product. The scope includes but is not limited to:

• Architect, design and ship the core Restate UI: from whiteboarding sessions with engineers to production-ready code.

• Show what the system is actually doing: execution timelines, retries, queues, state, failures. People come to the UI to work out what happened, often while something is on fire, and it has to get them there quickly.

• Build for data at scale: large result sets, live updates, filtering and search that hold up, and the charts and timelines that sit on top of them.

• Design the states nobody designs: loading, empty, partial, error, one result and far too many. A developer tool is won or lost in those, and they're usually the ones that get skipped.

• Keep it fast: Restate is a low latency runtime and the UI should feel like one. Rendering cost, data loading and perceived latency are design decisions here, not a cleanup pass at the end.

• Keep one mental model: developers meet the same concepts in the UI, the SDKs and the docs. They should be named and presented the same way wherever someone runs into them.

• Bring durable execution to life visually: the current Restate product is loved for its simplicity in breaking down a technically complex product. You'll make sure we keep shipping at the same design bar.

• Build scalable design systems in code: reusable components and patterns for architecture, code, and interactive elements that others can benefit from.

The profile

We’re looking for a design engineer with strong opinions and a portfolio that backs them up, with work you’ve both designed and built. You should be comfortable operating with significant autonomy, working directly with the founding team, and pushing back when the team is wrong.

Must-haves:

• Production front-end skills. React, TypeScript, and modern HTML/CSS. You can take a feature from concept through to shipped and deployed yourself, without waiting on an engineer.

• A portfolio of shipped work, where we can see both the craft and the code behind it.

• Strong design sensibility. A high visual bar you can hold across the whole product, without waiting for someone to set the direction first.

• Information design. Turning a lot of data into something a person can read quickly. Hierarchy, density, progressive disclosure, and knowing what to leave out.

• Data-intensive interfaces. Datasets bigger than the viewport. Pagination, virtualization, filtering, search, and charts built on real data rather than a tidy sample.

• Front-end performance. You've profiled and fixed slow rendering, long lists, wasted re-renders, bundle size. Ideally you can point at numbers either side of the fix.

• Visual storytelling for technical concepts. Show us how you've made something complex feel obvious.

• Motion design ability, built in code. Motion as a way to communicate state, time, and dynamism.

• Design systems in code. Components and patterns that stay coherent as other people build on them.

• Reading beyond the front end. API specs, queries, backend code. You don't have to write the backend, but you should be able to read it and work out what's going on.

• AI literacy. You're using AI to multiply your own impact and to unblock yourself. You're not waiting for an engineer to help you take something live.

Nice-to-haves:

• Prior work on a developer tools, infrastructure, or AI product. Familiarity with the developer audience and what "great" looks like in this space.

• Data visualization: timelines, traces, graphs, time series with more data points than pixels.

• Accessibility and keyboard-first interfaces. We're not where we'd like to be here, and we'd like the next person to care about it.

• Creative development experience: 3D, generative, or game-like web work (Three.js, GLSL shaders, and the like).

• Comfort reaching into the backend when a feature needs it.

• Comfortable deploying and owning something serverless yourself: Cloudflare Workers, Vercel, or similar, with a working grasp of edge runtimes, caching, and cold starts.

Not a fit:

• You want to lead a design team rather than be the senior IC doing the work yourself.

• You expect a finished design to hand off, or heavy direction. We need someone who arrives with a point of view and builds.

• You’re a designer who doesn’t code, or an engineer who doesn’t sweat the visual details. This role needs both.

• You’re not interested in technical subject matter. Our surface area is wide, and the role lives or dies on translating it.

• Location: remote in Europe preferred; US remote for exceptional candidates

• Travel: minimal; occasional team offsites.
