Product Designer

About The Position

Arcade is seeking its first Product Designer to build the UX/UI function from scratch. This role will initially focus on the Dashboard, the primary surface where customers decide to trust their agents with real systems. The designer will be responsible for shaping the user experience and interface of this critical component, as well as future products like MCP Apps and other yet-to-be-named surfaces. The company is at the forefront of enabling AI to take real-world actions by building the infrastructure for agentic 'tools' that allow AI models to interact with real systems at an enterprise scale. This is a unique opportunity to define a new design space, establish design best practices, and influence the future of AI applications.

Requirements

3–5 years of product design experience, with at least one role focused on a developer-facing or B2B SaaS product. Formal title matters less than the work.
A portfolio that shows end-to-end product work — research → flows → interaction → visual → shipped pixels, not just static screens.
Strong fluency in Figma. Fast, organized, components and tokens you'd actually want to inherit.
Comfort with technical product spaces. You can read enough about APIs, auth, and agent behavior to design for them — and you ask the right questions when you can't.
Demonstrated ability to run customer research without a dedicated researcher. You've talked to real users, synthesized what you heard, and changed the design because of it.
Strong partnership with engineering. You've shipped real product alongside engineers and made the work better for it.
Opinions on design systems — not just visual consistency, but how tokens, components, and patterns hold up as a team scales.
Comfort with ambiguity — early team, narrow charter that will expand. You make good decisions with incomplete data.
An insatiable desire to ship.

Nice To Haves

You've designed for AI, ML, or agent products before — and have opinions about what makes them work.
Prior experience at a developer-tools, API-platform, or infrastructure company (Stripe, Vercel, Supabase, Auth0, Postman, Linear, and the like).
You've shipped or substantially contributed to a design system that survived contact with multiple engineers.
Comfort designing for engineers as your primary user — you understand what makes an admin UI feel right to someone who'd rather be in their terminal.
Prototyping in code, even at a basic level. A designer who can read React and prototype interactions in the actual codebase moves faster than one who can't.

Responsibilities

Own the design of major Dashboard surfaces end-to-end — flow, interaction, visual — from first sketch to shipped pixels.
Run customer research with the AI/ML architects deploying Arcade. Interview them. Watch them use prototypes. Bring the signal back to the team.
Pair daily with engineering. Hand off in Figma, watch implementation in our React + Tailwind codebase, and iterate when production reveals something the mock didn't.
Shape the design system alongside engineering. We use Radix and Tailwind today; what we ship next either reuses, extends, or replaces those patterns deliberately.
Make agent state legible — tool execution, auth scopes, observability, billing. All of it has to feel obvious in the moment a customer needs the answer.
Write the design rationale. Explain decisions so engineers, the PM, and Marketing can build on them — and so customers learn the model from the product itself.
Set the bar for design quality as Arcade grows. Your patterns get inherited by every designer after you.
