Founding Product Designer

TierZero • San Francisco, CA

2d • Onsite

About The Position

As our founding product designer, you’ll help invent and build the core product experience from the ground up. You’ll work directly with the CEO, CTO, and engineering team, and spend real time with customers. This is not a polish role — design at TierZero is deeply intertwined with system behavior, trust, and operator judgment. Things change regularly, and here are examples of the types of work you’ll be doing:
Design core workflows and dashboards for AI agents that investigate incidents and production issues
Translate complex system behavior (confidence, uncertainty, provenance, partial results) into clear, trustworthy user experiences
Define guardrails and interaction patterns so automation is safe, reversible, and predictable
Partner tightly with engineers to shape product decisions, defaults, and failure modes — not just visuals
Design dense, high-signal interfaces for engineers operating under time pressure
Help define how humans supervise, correct, and collaborate with AI agents
Create interaction models for long-running, multi-step agent workflows (state, memory, async progress)
Iterate rapidly with customer feedback from real incidents and on-call scenarios
Contribute to everything from product direction to sales demos to onboarding flows to office snacks

Requirements

• Has a valid US Visa or work permit
• Works in SF in person 3 days a week
• 6+ years of experience as a product designer
• Has designed complex systems, dashboards, or internal / operator-facing tools
• Is comfortable with dense information, tradeoffs, and designing for failure modes
• Thinks in workflows, states, and guardrails — not just screens
• Is deeply product-minded and customer-first
• Can collaborate tightly with senior engineers and challenge decisions when needed
• Has worked at a startup before (or a high-bar product team) and survived
