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.

The Role:

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.

You’ll design across:

• 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.

What You’ll Own:

• 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

What We’re Looking For:

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

What You’ve Done:

• 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

Bonus:

• Experience designing workflow-heavy products

• Experience with operational tools, marketplaces, or coordination systems

• Comfort with prototyping and working close to code

How We Work:

• Small team, high ownership

• Product and engineering are tightly coupled

• We ship quickly and learn from real usage

Compensation Range

• $150,000 - 200,000 based on experience

• Equity in early-stage business (first 15 employees)

• Full benefits package
