What You’ll Be Launching

As our Senior People Business Partner (UK & US GTM), you’ll serve as the primary People partner for our UK entity while supporting leaders across our US Go-to-Market organization. Partnering closely with the GM of International Business and GTM leadership, you will balance strategic consultation with hands‑on execution—navigating employee relations, organizational design, workforce planning, and change management across both employment landscapes.

We’re building a team of sharp, creative people who love solving hard problems. We value curiosity over ego, initiative over waiting for permission, and people who genuinely care about doing great work. Bring your expertise, your fresh ideas, and your drive. We’ll bring the rocket fuel.
