Founding Product Designer

Founding Product Designer for Stealth startup

Location: London (Kings Cross) – on-site 4–5 days per week

Compensation: £100–130K+ (depending on experience)

Our client is a stealth-mode communications and AI startup founded by early Facebook product engineers. Backed by top-tier venture capital and respected angel investors, they are rethinking how people connect and get work done, combining the power of AI with human-centered design.

The founders are engineers with a strong eye for UI, and every pixel in the product so far has come from them. Now they're looking for their first design partner: the fourth person to join the team, and the first hire outside of the founders. That's how much they value design.

The Role

Looking for a Founding Product Designer who can move fast, design with clarity, and bring ideas to life on screen. This role is hands-on: prototyping, iterating, and shipping product with speed and precision.

You'll design for web and mobile (iOS/Android), helping to solve complex product challenges like how AI fits into human workflows, whilst ensuring the product feels personal, intuitive, and connected.

What You'll Do

• Design intuitive, aesthetically sharp experiences across web and mobile.

• Rapidly prototype and iterate in Figma (or your preferred tools).

• Collaborate daily with founders to turn product ideas into polished UI.

• Balance speed with user insight, always considering real-world use cases.

• Explore new ways to integrate AI while keeping human connection at the center.

• Bring fresh ideas, challenge assumptions, and push the team to think differently.

About You

• Strong track record designing consumer-grade products with high aesthetic quality.

• Skilled at simplifying complex problems into elegant user experiences.

• Scrappy and execution-focused—you get pixels on screen fast.

• Comfortable with ambiguity and motivated to shape a product from zero to one.

• Open, collaborative, and able to give and receive feedback well.

• Bonus: technical fluency or ability to tweak code (e.g. CSS, HTML, React, React Native) (not required).

Why Join Us

• Impact from day one: Shape the product and company from the ground up.

• Design-led culture: Work with founders who deeply value design.

• Strong backing: Supported by leading VCs and respected angel investors.

If you're excited to design the future of AI-powered communication, we'd love to hear from you!
