Senior People (HR) Operations Manager

About Monstro

Monstro is the operating system for governed financial intelligence. We build governance and intelligence infrastructure that enables artificial intelligence to operate safely, explainably, and at institutional scale.

We exist because the level of financial guidance historically available to a small group should be accessible to many more people. By combining AI with deep institutional infrastructure, we help financial institutions deliver more personalized, responsible, and life-changing financial support to millions of individuals.

We’re building mission-critical systems in a highly regulated domain, and we care deeply about doing it right. If you’re motivated by meaningful problems, high standards, and shaping infrastructure that improves financial outcomes, you’ll feel at home here.

About the Role

This is a hands-on Senior People (HR) 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.

What You’ll Own

HR Operations & Compliance

• Run and improve the US HR infrastructure via Rippling, serving as the lead for all HR Rippling matters — including implementation and the full cycle of the Rippling People platform
• Own and maintain employment documentation, policy frameworks, and compliance processes across all states where we operate
• Keep the full employee lifecycle running smoothly and compliantly — from offer letters and onboarding through to off-boarding
• Manage and support your People Operations team member

People Support

• Be the first point of contact for employee queries — benefits, policies, payroll, and everything in between
• Handle employee relations matters with good judgment, appropriate care, and in accordance with US and state employment legislation
• Make sure employees feel supported and that the basics are always done well — because a high-performing culture starts with trust

Employee Engagement & Performance

• Help run Performance Collaboration Conversations, goal-setting processes, and feedback programs in close partnership with the Talent & People Growth team — all with a focus on driving a culture of high performance and continuous growth
• Own the new joiner experience through 30/60/90 data and insight, turning what you learn into meaningful initiatives that improve engagement and set people up to perform from day one
• Lead efficiencies and speed using AI tooling to keep people data and systems accurate and up to date, using it to spot trends and inform decisions

Culture, People Engagement & Experience

• Support the delivery of culture and engagement initiatives that reinforce our values and raise the bar on what it feels like to work here
• Help coordinate the development of employees, manager toolkits, and internal communications that equip people to grow and perform at their best

Compensation & Governance

• Support compensation administration, market benchmarking data pulls, and off-cycle review processes
• Maintain pay and HR governance records accurately and in line with company standard operating procedures

What We're Looking For

• 5–8 years of HR or People Operations experience, ideally in a fast-paced, high-growth, or tech environment
• AI Labs, Foundation Model Companies, Fintech, BankingTech, or regulated industry experience is a strong plus
• A genuine belief that great People Ops is a driver of high performance — not just a support function
• Strong operational depth — payroll, compliance, benefits, and systems — this is the core of the role
• Experience working across multiple US states, with confidence navigating the complex compliance landscape that comes with it
• Highly organized with sharp attention to detail — you don't let things fall through the cracks
• A people-first approach — warm, responsive, and genuinely invested in helping people do their best work
• Comfortable with ambiguity and happy wearing multiple hats in a fast-scaling business
• Hands-on experience with modern People platforms — Rippling and AI-powered People tools
• Bachelor's degree or equivalent experience; SHRM-CP or PHR a plus

A Note on Interviewing: We sometimes use AI note-takers to help us transcribe interview notes, so we can be more present in your interview. If you’d like to opt out of us using automatic transcribers, please note this in the free text field in your application, otherwise we’ll take your application as confirmation that you’re happy for us to use notetakers (whether added to video calls or in the background).
