Key Responsibilities

  • Design end-to-end product experiences for an AI-powered B2B SaaS platform
  • Create generative and non-deterministic interfaces that adapt to user sessions
  • Implement designs as functional front-end code using Claude Code
  • Test work on staging environments and push pull requests to production
  • Synchronize design and code using Figma with MCP-based workflows
  • Contribute to the overall brand identity and product presentation

Requirements Snapshot

  • Proven B2B SaaS design experience with a portfolio of live work
  • Hands-on coding ability with AI tools like Claude Code
  • Experience designing generative or non-deterministic user interfaces
  • Proficiency in Figma including design-to-code workflows and tokens
  • Ability to build brands and product experiences from scratch

Expected Impact

The designer will bridge the gap between design and engineering by shipping real components and defining the visual identity of an AI-first product. Their work will directly influence how users interact with non-deterministic AI outputs, ensuring a polished and functional experience that goes beyond static mockups.

Job Description

An AI-native recruiting startup building a voice-first job-search experience is looking for a Senior UX/UI Designer & Builder — someone who doesn’t stop at the mockup.

Also searchable as: Product Designer (AI/SaaS) | Design Engineer | Senior Product Designer & Frontend Developer | UX/UI Designer & Builder.

You’ll own the design vision for an AI-powered B2B SaaS product and build it — using Claude Code to implement your own designs, test on staging, and ship PRs live. This is a hybrid design + engineering-adjacent role for someone who thinks in both craft and code.

What you’ll do - Design end-to-end product experiences for an AI-powered B2B SaaS platform, including brand and UI presentation. - Design and build generative, non-deterministic interfaces — UI that adapts per session/user rather than following fixed static states (loading, partial results, streaming content, AI uncertainty). - Use Claude Code (or equivalent AI coding tools) to implement your own designs as real, working front-end code. - Test your work on staging and push PRs to production. - Use Figma with MCP-based workflows (Figma-to-code, design tokens, component sync) to keep design and code in sync. - Contribute to brand and product identity — not just screens, but how the brand and product experience feel as a whole.

Who this is a fit for - Proven B2B SaaS design experience — ideally with live, shippable work available to review today (not just static portfolio shots). - Real experience building brands and product experiences, not only executing within an existing design system. - Hands-on coding ability — comfortable using Claude Code (or similar) to prototype or ship real front-end code. - A lean-code mindset — writes/reviews dependency-light, bloat-free front-end code; no unnecessary libraries or premature abstraction. - AI-native interface experience — has actually designed and shipped generative or “undeterministic” UI, and is comfortable designing for ambiguity rather than fixed states. - Strong Figma skills, including MCP-based design-to-code workflows. - An eye for how features look and are presented — polish and presentation matter as much as function.

Nice to have - Experience naming/positioning a product alongside visual design (full brand ownership). - Familiarity with component libraries (e.g. shadcn, Radix) and keeping custom AI-driven UI consistent with a system.

Engagement details Initial 4-week contract to assess fit and momentum, with the intent to extend to 3+ months for the right person. Deliverables in the initial period will likely include brand/product direction, key flows and screens, and working, shipped components — not just mockups.
