Senior Product Designer

About Cassi:

Cassi is the coordination layer for the people who manage assets in the physical world. We start with property managers, tying their teams, schedules, tasks, and routines into a single system powered by an intelligence layer that knows the assets inside and out and puts real AI to work across the operation. We closed our Series A in six days. Investors, customers, and the team are all in, and we're moving accordingly.

We’re hiring our first full-time Senior Product Designer. This is not a “make screens in Figma” role. You’ll help own how the product works. You’ll take messy, real-world workflows—texts, calls, emails, vendor coordination, scheduling—and turn them into simple, intuitive systems that people rely on every day.

• Web
• iOS / Android
• Multiple user types (property managers, operators, vendors)

And you’ll help define how AI shows up in the product in a way that feels natural, useful, and differentiated.

• Turn complex, real-world operations into simple, elegant product experiences
• Design end-to-end flows across web and mobile, not just isolated screens
• Build for multiple user types and permissions across a shared system
• Partner deeply with product and engineering to ship quickly and iterate continuously
• Help define and evolve Cassi’s product design language and brand through the product
• Introduce and scale a design system that supports speed without sacrificing quality
• Use AI tools to accelerate and shape design, prototyping, and iteration cycles

Builder mindset:
You’ve built 0→1 products or features from scratch. You’re comfortable operating without full specs or structure. You move fast, make decisions, and iterate

Product thinking > pure design:
You think in systems, not just screens. You understand tradeoffs between UX, engineering, and speed. You care about outcomes, not just polish

Strong execution across platforms:
You’ve designed for both web and mobile (iOS/Android), with a mobile first mindset. You understand the differences and design accordingly. You’re comfortable owning full flows end-to-end

AI-native curiosity:
You actively use tools like Claude Code or similar. You understand how AI is changing design ->
Dev handoff. You use AI to speed up iteration, not replace thinking

High agency:
You don’t wait for direction—you create it. You push for clarity where none exists. You’re comfortable being the first and setting the bar

• Designed and shipped 0→1 product experiences that are live and used by customers
• Owned complex, multi-step workflows end-to-end and made them meaningfully simpler
• Worked side-by-side with engineers to ship quickly, make tradeoffs, and iterate in production
• Built or scaled a design system that improved speed and consistency across the product
• Made product decisions informed by real usage, not just design best practices
• Operated in ambiguity, defining problems and driving solutions without clear direction

• Experience designing workflow-heavy products
• Experience with operational tools, marketplaces, or coordination systems
• Comfort with prototyping and working close to code

• Small team, high ownership
• Product and engineering are tightly coupled
• We ship quickly and learn from real usage

• $180, based on experience
• Equity in early-stage business (first 15 employees)
• Full benefits package
