About The Position

Basis Technologies is looking for an Office Manager & Payroll Specialist to join our growing US team in Irving, Texas. This is a varied, hands-on role for someone who enjoys ownership and doesn't want a job that fits neatly into one box. You'll keep our Irving office running smoothly: onboarding new starters, managing building access, coordinating equipment with our IT team, and being the first point of contact for day-to-day office needs. Alongside, you'll be the go-to person for US payroll tax compliance, working closely with our UK-based Payroll Manager to keep filings, registrations and notices on track across every state we operate in. It's a role built on trust and initiative. You'll work closely with our Payroll, HR, IT and Finance teams, each of whom will support and train you, but the ownership on the ground is yours.

Requirements

Prior experience in managing a scaling office environment
Experience organising company-wide events (i.e. holiday party's)
Demonstrable knowledge of US payroll tax compliance, ideally across multiple states
Comfortable liaising directly with tax authorities and resolving notices independently
Experience registering and maintaining payroll tax accounts
A hands-on, adaptable approach, equally comfortable with compliance detail and everyday office logistics
Strong organizational skills and comfortable managing a varied workload
Based in, or able to work on-site in, Irving, Texas
