Founding Product Designer

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

Compensation: £100-130K + equity

We’re excited to share that we’re hiring a Founding Designer for Slashwork which has officially come out of stealth!

Slashwork has raised $3.5m, led by 20VC, after being incubated by them, and this is a genuinely interesting story in the future of work space.

The founding team are ex-Facebook engineers who helped ship some of the platform’s most foundational products, including News Feed, Groups, Timeline, developer APIs, and Workplace itself. The founding engineering team includes Jackson Gabbard, Dave Miller and Josh Watzman.

Slashwork is building a new asynchronous communication platform designed to enable work rather than overwhelm teams. They’re currently working with a small number of companies ahead of a broader rollout later this year.

The round includes participation from an exceptional group of operators and angels, including Julien Codorniou, who previously led Facebook’s Workplace, as well as Sheryl Sandberg, Cal Henderson, Des Traynor, Will Shu, and leaders from Slack, Intercom, Dropbox, Microsoft, Instacart, and Facebook.

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 Slashwork

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.
