Principal Product Designer

Guild.ai•San Francisco, CA

3d•$240,000 - $290,000

About The Position

Guild is the control plane for AI agents - a platform to build, deploy, govern, and share agents in production. As AI moves from experimentation to real systems, we're building the infrastructure layer that makes it safe, observable, and scalable. We're looking for a Principal Product Designer who's ready to roll up their sleeves and do some of the most interesting design work in AI infrastructure right now. Guild's design team is small, flat, and full-stack - everyone ships, and everyone has real ownership over the quality of what we build. You'll work across product surfaces alongside engineers, researchers, and founders, moving fast from problem to solution without losing sight of craft. Design and product work as one team here - setting priorities together, moving in the same direction. But there's real autonomy in how you get there. You'll be expected to make calls, ship, and learn without needing sign-off at every step. In this role you'll bring an AI-native workflow to everything you touch - using AI to think faster, prototype quicker, and push quality higher. We're building an AI product, and we expect our design practice to reflect that - experimenting with new tools, pushing what's possible, and helping define what AI-native design looks like at a company like Guild. Low ego, high craft. That's the team you'd be joining.

Requirements

8+ years of product design experience with a portfolio demonstrating strong craft, systems thinking, and the ability to simplify genuinely complex workflows
Already working in an AI-native way - AI tools are embedded in your process, not just something you're starting to explore
Experience building AI-powered design solutions or designing for AI-driven products
Fluent across web and mobile design with a strong design process and foundation - Figma, prototyping tools, and whatever else gets the idea across fastest. Design-led first, technical second
Technically fluent in complex product spaces - comfortable with front-end constraints, and has hands-on coding experience, whether production code or vibe coding to get ideas across
Low ego, high craft - you care about the work and you're energized by collaboration

Nice To Haves

Experience in AI infrastructure, developer tools, or enterprise SaaS
Familiarity with agent-based systems, observability tooling, or deployment workflows
Experience at a category-defining company in an emerging space
Background at an early-stage company navigating PMF - comfortable with ambiguity, fast pivots, and a bias toward shipping and learning

Responsibilities

Bring a strong, opinionated perspective on how the product should serve our users and where it should go - actively shaping product direction, roadmap priorities, and PMF decisions alongside product and engineering, not just executing on them
Design across the full product experience for two distinct but connected audiences enterprise buyers who need clarity and confidence to adopt, and developers and technical users who demand precision, depth, and tools that respect their workflow
Own problems end-to-end within your product team, from early discovery and problem framing through prototyping, validation, and shipping production-quality solutions
Translate complex AI infrastructure concepts - agents, observability, governance, deployment - into experiences that feel intuitive and trustworthy regardless of the user's technical depth
Contribute to the design system by raising the quality bar on shared components, patterns, and interaction standards - thinking in systems, not one-offs
