Responsibilities
• Partner with managers across the UK as their first point of contact for people matters. • Coach managers through performance, feedback, development, and day-to-day people challenges. • Be our in-house expert on UK employment law and make sure we stay compliant as we grow. • Manage employee relations issues, including performance, absence, disciplinary, and grievance processes. • Own UK benefits and work with brokers and vendors throughout the year. • Support recruiting by screening candidates and partnering with hiring managers on UK roles. • Help new hires get off to a great start. • Keep the London office running well, from team events to office supplies to helping us plan for future growth. • Work closely with Finance to support payroll and pensions. • Build simple, scalable People processes that help us grow without adding unnecessary complexity • Managers come to you for advice because they trust your judgment. • Employees know who to go to and feel supported. • Our UK policies, benefits, and compliance processes are well documented and running smoothly. • Payroll and benefits are accurate and predictable. • Hiring managers receive better support throughout the hiring process. • The London office feels organized, welcoming, and connected to the rest of the company. • You've made the People team stronger than you found it. • YOU MIGHT BE A FIT IF… • You’ll probably enjoy working on this team if… • Your first instinct is "I'll figure it out." • You don't mind jumping between very different kinds of work. • You like building things instead of maintaining someone else's systems. • You don't see a difference between "strategic" and "operational" work. • You enjoy working with smart people who ask good questions and aren't afraid to challenge ideas.
Benefits
• You'll become the trusted People partner for our UK team. You'll coach managers, support employees, own UK compliance, improve our processes, help with hiring, and make sure the London office is a place people enjoy coming to. • You'll have a lot of ownership. We trust people to make good decisions, and we expect you to help shape how People Operations evolves in the UK, not just execute someone else's playbook. • This is a true generalist role. You'll probably enjoy it if you like switching context, wearing a lot of hats, and building things from scratch. • Some days you'll be helping a manager navigate a difficult employee conversation. Other days you'll be screening candidates, auditing our HRIS (Rippling), reviewing benefits, supporting payroll, planning an office event, or figuring out whether we need a bigger office. • If you're looking for a role where you only do strategic work, this probably isn't it. • You'll get to work with incredibly smart, kind people who care deeply about what they're building. It's fast paced, there's always something new to learn, and you'll have far more ownership than you'd get at a larger company. • We're still small enough that every hire changes the company. • If you're looking for a role where you can build, make decisions, and have a real impact, you'll find that here. You'll work closely with experienced leaders, help shape how we scale, and have a direct hand in building the kind of company people want to work at. • Recognized momentum - We made the Rising in Cyber 2026 list, a signal that the market is taking notice • Rare market opportunity - Join early in a category-defining company at the convergence of AI and security, where your work directly shapes how enterprises tackle one of the biggest unsolved problems in tech • Competitive pay and meaningful equity - A real stake in Harmonic's success, not a token gesture • Comprehensive benefits - 401K, pension plan, generous PTO, and flexible hybrid work • A small, high-trust team that values transparency, creativity, and continuous learning - no politics, no bureaucracy • Thoughtful leadership - that cares deeply about your growth, not just your output • Annual global off-sites - past trips include Lisbon, Portugal and Nashville, TN • Real ownership - you'll shape the product, the culture, and the direction of the company from day one • HARMONIC'S CORE VALUES • 🌱 FLOURISH IN THE UNKNOWN • We embrace new, unfamiliar situations that require initiative and rapid decision-making. We orient ourselves quickly and deliver results with minimal guidance. • We raise our hands, take on challenges, and assist others whenever possible. We hunger for opportunities to learn and do more. • 🤝 PERFECT HARMONY • We support one another to create cohesion and unity. We collaborate openly, share feedback honestly, and help everyone produce their best work.
