Founding Designer (San Francisco)

About Multiply Multiply is a fast-growing AI startup that helps B2B companies scale paid ads and get discovered by their dream customers. Traditional ads campaigns decay over time. Multiply builds self-learning growth ads that continuously improve performance by combining AI with expert operators.

We are 13 people today. You would be #14 .

Role Description You will lead across 3 critical parts of our company:

• Brand design for ads we build for our customers. Oversee contractors and our AI designer, and deliver stellar ads for our customers
• Lead product strategy for our AI that builds creative for customer ads
• Product design across our product and features

As our first designer, you’ll define how modern B2B marketing tools should look, feel, and work — from product UX to visual identity. You'll have an important voice in our brand design, product direction, and vision.

This is a full-time Product Design role. The current team is in San Francisco, and this role is in person at Multiply HQ.

We work hard and we know we're building a generational company. If you're looking for the ride of a lifetime, this might just be what you're looking for.

What You’ll Do

• Help us scale marketing assets for high growth companies
• Own product design from end to end: workflows, dashboards, onboarding, agent UX, etc.
• Collaborate closely with founders and engineers to build fast and iterate
• Train our AI to help customers with their brand and Ad design
• Set up our design systems, workflows, and long-term design culture
• Talk to users, gather insights, and turn them into product magic

Qualifications

• 3–8+ years of product/UX design experience, preferably at startups or 0→1 products and in SaaS or B2B
• A portfolio that shows off clean, user-focused design and systems thinking that you can share
• Fluency with design tools (Figma, etc.) and a love for prototyping
• Ability to work independently and make bold design decisions
• Comfortable working in ambiguity and moving quickly
• Interest in AI/LLMs is a bonus — but a great design mindset is key
