Senior People Operations Manager

Monstro•New York, NY

1d•$141,000 - $171,000

About The Position

This is a hands-on Senior People Operations Manager role at the heart of a fast-moving BankingTech AI company that's genuinely changing how financial guidance reaches people. You'll be the engine behind our US People function — the person who makes sure the foundations are solid, the processes run smoothly, and employees have a great experience at every stage of their journey with us. We're building our People function the way the best AI Labs do — lean, intentional, and high-impact. That means thoughtful org design, a culture built on trust and performance, and operations that actually work. You'll be central to making that real in the US. You'll work closely with our Global Head of Talent & People Growth and report into the Chief Product Officer, with a member of People Operations alongside you to support the day-to-day. This isn't a strategy-from-a-distance role — you'll be in the detail, owning the work, and helping build an environment where people do the best work of their careers. No two days look the same. You might be sorting a multi-state payroll query in the morning, onboarding a new engineer in the afternoon, and drafting a policy update before the day is done. If you take real pride in doing People Ops properly — and you believe that getting the fundamentals right is what unlocks a high-performing culture — you'll fit right in here.
