Our US team is growing fast, working alongside national labs, HPC centers, and government agencies to bring quantum computing into the real world — and we're looking for our first dedicated Office Manager to build the operational backbone of our US presence.

Manage US payroll and benefits administration (via Gusto and external partners), including annual benefits renewal and open enrollment

Prepare, issue, and maintain offer letters, contracts, and amendments, ensuring compliance with state-specific employment requirements

Own financial administration for the US subsidiary: budget tracking and reporting, expense management, corporate card programs, and vendor/invoice follow-up

Act as the main liaison with external HR, payroll, and legal/immigration partners to keep the US entity compliant

Support visa and immigration processes (H-1B, O-1, green card sponsorship) alongside immigration counsel

Help organize US team events, offsites, and other team-building moments

Continuously improve HR, finance, and admin processes as the US team grows
