Software Engineer, Full Stack

Our mission is to help organizations turn any growth idea into reality.

We see growth as a creative practice, not a formula. Finding and reaching your best-fit customers takes unique ideas and constant iteration. As AI makes execution faster and tactics easier to copy, creativity is the only lasting advantage. We're already helping thousands of customers — including Anthropic, Notion, Google, and Ramp — go to market with unique data, signals, and AI research.

In 2025, we raised a $100M Series C backed by world-class investors including Sequoia, CapitalG, and First Round — and crossed $100M in revenue.

In 2026, we announced our second employee tender offer in 9 months at a new $5B valuation. We also launched a community equity round, for our customers, agency partners, and club members.

Some things to know about us:

• Our community includes 11,000+ customers, 150+ integration partners, 125+ agencies, 50+ Clay clubs, and 30k members on Slack.

• Our culture is unique inside and outside of work. Our team members are also DJs, activists, writers, clowns, marathoners, skydivers, psychedelic therapists, social workers, and more.

• All employees can work for free with world-class coaches who specialize in creativity, management, and more.

• Our operating principles — including negative maintenance and non-attached action — guide our work. Read more about them here.

• Read about us in the NYT, Forbes, First Round Review, and more.

What You’ll Do

• Drive product strategy and execution. You’ll work with a team of engineers and cross-functional partners across design, data science, and GTM to define a product strategy and drive execution through conception, research, implementation, and maintenance.

• You love being a product manager as well as an engineer. Our product engineers drive and own products from end to end.

• You love to collaborate with others to ship high quality, thoughtful features. You are able to talk to customers, think through multiple approaches, and work with our teammates to find the right solution for each problem. You care about craft and translate the solution into bug free, easily understandable code and raise the engineering bar for those around you.

• Having a diversity of perspectives is important to you. You believe that having people with different backgrounds and perspectives creates a better team and a more holistic product.
