The Opportunity

We're hiring a Principal Product Designer to lead design for the Trampoline pod, one of the most important bets in our Growth organization over the coming year. We started as Grammarly, and we've been rapidly adding new teams and products to our portfolio to become Superhuman - from Coda, Superhuman (Mail), Rows, and most recently GPTZero. It doesn't end here!

The "trampoline" is how we grow our newest products dramatically faster than they could grow on their own - by using our distribution to over 40 million Grammarly users, our shared services, and the network effects of a combined suite to introduce the right product at the right moment. Done well, a user in one product discovers the next one exactly when they need it: drafting an email in Gmail and finding the Go AI assistant, working in an AI Editor doc and landing in SuperDocs, hitting a moment in Grammarly where Mail becomes obviously useful.

It’s a multi-product, multi-surface design challenge - and we’re looking for the right design lead to help us build the foundations and playbook for it with a dedicated squad of PMs, Engineers, Lifecycle Marketers, Data Analysts and Researchers.

This is a role for a designer who is a strategist, systems thinker, craftsperson, and builder/tinkerer. You’ll own the end-to-end experience of how users cross the seams between products, help decide how centralized versus distributed this work should be, and set a new bar for how compelling and desirable a multi-product experience can feel... an intentional, well-branded conversation with Superhuman as a company.

What you’ll do

Own the design vision for the trampoline motion. Define cross-product journeys, entry points, and activation loops that move users from one Superhuman product into the next - end to end, across our self-serve customers. Partner with managed growth in the long run.

Nail the hero journeys and set multi-product design strategy. Partner with Growth, Product, and leadership to identify and design the three-to-five highest-value cross-product journeys (for example, Grammarly to Go, AI Editor to SuperDocs, Grammarly Gmail users to Mail Agent) and make them feel effortless and inevitable. Help shape coherent suite journeys and partner with other designers on how much of the trampoline is run within each product team.

Partner and guide the service design lens. You’ll have the support of a service designer to think about design across the full system of touchpoints, lifecycle stages, channels, and moments - including in-product prompts, modals, cross-sell surfaces, onboarding into a second product, and the bundle experience.

Expand a desirable, branded system. Use your visual design skills to expand how the Superhuman brand is perceived across historically under-designed growth surfaces, and how the intentional voice and tone of the suite should appear.

Tinker at the frontier of AI and tooling. Prototype with new AI approaches and emerging design tools, and bring the team along. You’re the kind of designer who plays with what's new, explores the edges of what and how we do work, and turns it into repeatable practice through inspiring others.

Prototype to think. Communicate through interactive mocks and functional prototypes, using making as a mode of exploration, not just presentation.

Productize the growth engine through design. Help turn one-off wins into a repeatable system - patterns, templates, and playbooks - that can be deployed quickly and predictably on every new product that joins the portfolio.

Elevate craft and lead through influence. Set a high bar across the Growth Design team, mentor designers of all levels, and drive cross-functional alignment as a design leader partnering with Product, Engineering, Data Science, Lifecycle, and Sales.
