Michaela Shanahan
@michaelashanahan
HR Manager and Payroll Specialist with 10 years leading remote HR, compliance, onboarding, and payroll administration.
What I'm looking for
I’m an HR Manager with ten years of experience managing and coordinating HR functions while facilitating the planning and execution of policies and procedures. I bring strength across all aspects of HR management, including payroll administration, compliance reports, employment laws, and talent management.
Most recently, I worked in remote HR and payroll for California-based packaging design firms (Treeform Packaging Solutions, LLC and Packaging Options USA). I managed onboarding and offboarding, maintained staff files, ran bimonthly payroll, administered 401K and staff benefit packages, and advised leadership on state and federal regulations to ensure compliance.
Before that, I was the sole HR and Business Manager for a 100% virtual boutique PR firm (Bospar Public Relations) based in San Francisco, supporting remote operations nationwide. I initiated and maintained the 401K plan, managed compensation and benefits, advised on compliance, and handled accounts receivable/payable while also overseeing payroll and employment operations.
I’m comfortable advising leadership across risk and operations—managing PTO and family leave, workers’ comp, and maintaining the company handbook. I also bring a start-up mindset from acting as an HR consultant for tech start-ups, and I’m proud of being the dependable, hands-on partner who keeps details moving as a business grows.
