Senior Software Engineer (AI)

About this role

Our client is building the future of growth marketing. Our mission is simple : companies should pay for outcomes, not tools. To make that real, we've built a vertically integrated software and services stack that delivers exceptional growth results—fast, repeatable, and reliable. Today, we execute AI‑enabled SEO playbooks for companies like Rho, Clay, Descript, and Beacons. Tomorrow, we'll expand across every major growth channel.

Growth marketing is notoriously hard to get right. The best talent is scarce, agencies are slow and inconsistent, and quality often suffers. We're changing that. By pairing world‑class AI systems with a team of experts, we automate the hardest parts of growth and give our customers an edge that compounds over time.

Founded in San Francisco, our client raised over $20 M from First Round Capital, Basis Set Ventures, WndrCo, and angels including the growth leaders from Notion, Airtable, Webflow, and Dropbox. Our investors also include operators like Lenny Rachitsky and Eli Schwartz, author of Product‑Led SEO . We're backed by people who know growth inside and out—and we're just getting started.

Please note : This is an in‑person role at our Hayes Valley office in San Francisco. For those outside the Bay Area, we offer paid relocation.
