Job description

About Fluidstack

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you, please apply!

About the Role

We are hiring a Frontend Engineer to own the surfaces that define how the world perceives Fluidstack and how our internal teams operate. You will be the primary engineer across two high-visibility domains: our public marketing website and the internal tooling that powers our operational workflows. This is not a role where frontend sits downstream of design hand-offs. You will make architectural decisions, push visual quality, and ship code that matters to both external customers and the people running one of the fastest-scaling AI infrastructure companies in the world. You will work directly with design, product, and engineering leadership.

You Will

• Develop and operate our homepage: lead technical decisions on architecture, performance, and UX quality for our public marketing site.

• Build internal UIs: design and ship React-based interfaces for operational dashboards, data center management views, procurement workflows, and other internal surfaces that engineering and ops teams depend on daily.

• Establish and maintain a component system: build shared component libraries in React with Mantine and/or Tailwind that are documented in Storybook, adopted by the team, and held to a high visual and accessibility standard.

• Move fast with AI-assisted workflows: you actively use Claude Code, Codex, Cursor, or comparable AI tooling to accelerate development. You are not threatened by these tools; you amplify your output with them.

• Push interactive experiences: prototype and ship motion, transitions, and marketing-forward interactions using Framer where appropriate. Know when to use it and when to reach for lower-level primitives instead.

• Manage and extend our CMS/no-code layer: own integrations with Webflow or equivalent for marketing content workflows, with the judgment to know when no-code tooling is the right abstraction and when it is not.

• Drive frontend engineering quality: write clean TypeScript, enforce type safety, contribute to CI/CD, and set standards for component architecture, state management, and performance profiling.

• Collaborate cross-functionally: work closely with product designers, infrastructure engineers, and GTM stakeholders. Translate ambiguous asks into well-scoped implementations without needing detailed specs handed to you.

Basic Qualifications

• 3+ years of professional frontend engineering experience shipping production React applications.

• Strong command of TypeScript and hands-on experience with Mantine, Tailwind CSS, or similar frameworks in production applications.

• Experience building and maintaining a component library documented in Storybook.

• Shipped a public-facing marketing site with a high design bar and measurable performance requirements.

• Proficiency with modern React patterns: hooks, context, server components, and state management (Zustand, Jotai, or equivalent).

• Experience with PWAs, React Native, or other mobile frameworks.

• Comfortable with Git-based workflows, CI/CD pipelines, and reviewing your own PRs critically before asking others to.

• Ability to operate independently on projects without granular task breakdown; you identify what needs to be done.

Preferred Qualifications

• 5+ years of frontend engineering experience, with visible output at devtools, infrastructure, or technical SaaS companies.

• Fluency with Framer or Webflow for quick prototyping and similar exercises.

• Active and opinionated use of AI-assisted development tooling (Claude Code, Codex, Cursor, v0, or similar) with a clear point of view on where these tools accelerate output and where they introduce risk.

• Experience with Next.js App Router, including RSC patterns, streaming, and deployment on Vercel or similar edge runtimes.

• Exposure to data-heavy dashboard UIs: charting libraries (Recharts, Victory, Observable Plot), table virtualization, and real-time data via WebSockets or SSE.

• Design sensibility that goes beyond implementing specs: you have opinions about typography, spacing, and interaction detail, and can push back on decisions that lower the quality bar.

• Familiarity with technical infrastructure concepts sufficient to build tooling for data center and compute operations teams without needing domain concepts explained from first principles.

We are committed to pay equity and transparency.
