About the role

Government technology has failed citizens, public servants, and service members for decades. Kaizen powers America’s application layer. We replace the legacy systems federal agencies run on with modern software, built with craft. The ticketing platform a resident uses to visit a presidential library. The marketplace DoW uses for counter-drone procurement to protect lives and critical infrastructure. The system a Veteran uses to access benefits. We build systems of record, of national consequence. Our AI-native modules and harness allow us to do so in weeks and months, not years. This year, our revenue has grown 35x. Next year, our software will serve over 100 million Americans across dozens of federal agencies. Founded in 2022 and based in New York City and DC, Kaizen has raised $35 million from NEA, a16z, Accel, 776, and Carpenter Capital. THE ROLE The Kaizen team is growing and the back-office and people infrastructure that got us here (onboarding, payroll, benefits, compliance, office ops) is ready to scale. This is the first dedicated People Operations hire at Kaizen. You'll take ownership of the function, build the processes that grow with the company, and be the person employees and managers turn to across every stage of the employee lifecycle. WHAT YOU'LL DO - Own onboarding and offboarding end-to-end: offer letters, I-9 verification, background checks, tools provisioning, system access setup, HM coordination, 30/60/90 check-in process, and a clean, documented exit process every time - Run payroll operations - adding new employees, processing changes, troubleshooting issues, and ensuring every run is accurate and on time - Manage the benefits program day-to-day: open enrollment, carrier coordination, employee questions, a potential PEO migration, stipend maintenance, usage tracking, and feedback loops - Own people compliance across all active states: SOS registrations, unemployment insurance, quarterly and annual filings, employee records, handbook maintenance, and working fluency with tools like Mosey, Corpnet, and AbstractOps - Own employee engagement including pulse surveys, feedback initiatives, and sentiment tracking across a distributed team. Surface themes to leadership and turn feedback into actionable improvements - Support performance management cycles: mid-year and end-of-year reviews, manager check-ins, scorecard coordination, and keeping feedback loops tight without adding unnecessary process - Coordinate and manage office gatherings, employer branding events, and more intimate team outings - Spearhead future office relocation efforts including broker relationships, touring spaces, coordinating buildouts, and ensuring seamless move-in processes - Administer equity in Carta, partnering with the CoS and Finance on option grants, termination processing, and cap table hygiene - Partner with COO and Recruiting Lead on headcount planning, leveling, and compensation frameworks - Partner with Recruiting Lead on candidate experience and recruiting operations including interview coordination, offer letter workflows, ATS hygiene, and keeping the recruiting-to-people handoff clean - Use AI tools actively to automate repetitive workflows, draft communications, and build more scalable processes — this is an expectation, not a nice-to-have WHAT YOU'LL BRING - 4+ years of experience in People Operations, HR Operations, or related program management roles - Experience at one or more scaling startups where you operated without a full HR team behind you - Hands-on fluency with the core People Ops toolset: Gusto or Rippling, Carta, PEOs such as Sequoia or equivalent, and compliance platforms like Vanta, Mosey, or AbstractOps - Ownership mentality: you've run a people ops or back-office function yourself, not just supported someone who did - Comfort operating across people, finance, and admin functions without needing clean lane boundaries — this role crosses all thr
