About Rally UXR

Rally is the User Research CRM that helps product, design, and research teams talk to their users quickly, safely, and  platform automates the unglamorous parts of research—participant recruitment, outreach, screening, scheduling, consent, and incentives—so teams can spend more time learning from customers and less time wrestling with manual workflows.

We're now building Rally's next chapter: an AI-native platform that handles the full research lifecycle, end to end.

Trusted by teams at Google, Adobe, Figma, Git Lab, Webflow, and others. Backed by Y Combinator, Stage 2 Capital, and Canapi Ventures.

About the team

Our Engineering team is a highly collaborative, user‑obsessed group focused on making research smoother for both our customers and their participants.

• We work closely with UX Researchers, Research Ops leaders, designers, and product managers at some of the world’s most user‑centric companies.

• We use Rally to build Rally - talking to our own users frequently, running studies on our platform, and feeding insights straight into the roadmap.

• We favor small, empowered teams, high ownership, and a tight feedback loop between customers, product, and engineering.
