People Operations at Synthesia
At Synthesia, People Operations isn’t a support function, it’s the operational engine behind a company that’s scaling fast and moving with intent.
We build the infrastructure that keeps the business running smoothly. We design systems that reduce friction, create processes that actually work, and use data to drive better decisions. When something feels manual, messy, or unclear…we fix it.
In 2025, our focus was laying the foundations to support our growth. In 2026, we’re doubling down on building a People Ops function that is self-service, process-driven, and operationally excellent and designed to scale with the business, not slow it down.
This role is a key part of that evolution.
The Role
We’re looking for a systems-minded, hands-on People Operations professional to expand our US People Ops function as we continue to scale.
You’ll partner closely with our existing People Ops team of four ( Report to People Ops Lead and work alongside two UK/EMEA People Ops Specialists, and a US People Ops Specialist) to evolve how our operations run as we grow, while continuously improving our global infrastructure.
This role blends operational ownership with a systems mindset. You’ll be deeply involved in the US employee lifecycle while helping strengthen the systems, workflows, and data foundations that support our global People function.
If you thrive with ownership, care about clean systems, and enjoy building processes that hold up as a company scales - you’ll thrive here.
The role…
Own key US lifecycle processes end-to-end ( from onboarding, internal mobility, relocations, parental leave, promotions)
Partner with our US People Ops Specialist to deliver a genuinely top-tier onboarding experience
Own Rippling (our US HRIS) as the primary system administrator
Improve People systems, workflows, and integrations so they scale as we grow
Support US benefits administration and liaise with our broker to resolve queries smoothly
Manage employment contracts and People documentation with precision and care
Act as a key point of contact for US employee queries - unblocking and simplifying where needed
Ensure payroll-impacting changes are accurate, timely, and clearly communicated
Keep us compliant and audit-ready by proactively reviewing policies and labour requirements
Maintain clean, structured, and reportable People data
Identify and implement automation or AI improvements where manual work can be reduced
Own projects on our People roadmap that improve operational efficiency and scalability
About you
3–5+ years in People Operations, HR Systems, or a similar operational HR role (ideally in tech start up/scale up environments)
Strong HRIS experience (Rippling preferred)
Confident across onboarding, payroll coordination, benefits administration, and compliance
Experience improving workflows, implementing automation, or optimising systems
Comfortable working with People data and building reports
Highly organised with strong attention to detail
Proactive, solutions-oriented, and comfortable operating independently
Trusted with sensitive and confidential information
Bonus: You’ve implemented systems, built integrations, or embedded AI into operational workflows.
Compensation: $90,000-105,000 salary + equity. The final compensation package will be determined based on your experience, qualifications, and location.
