HR Advisor (Generalist)

Position Summary:
The HR Advisor at Mixam plays a critical role in supporting our most valuable asset—our people. As a core member of a lean, high-visibility global People team, you will be the primary HR point of contact for our US and Canada regions, while providing essential support for UK and Australian operations.

This is a true generalist role designed for a dynamic "hands-on" professional who thrives in a fast-paced startup or scale-up environment. You will manage the end-to-end employee lifecycle, from seamless onboarding to complex employee relations (ER) cases, ensuring our policies are not only compliant but also reflective of Mixam’s vibrant culture. Working closely with the Global Head of Talent & People, you will help bridge the gap between our international offices, ensuring consistent, high-quality HR support across all time zones.

Key Responsibilities:

• Employee Relations & Support: Lead and resolve ER cases including disciplinaries, grievances, and performance management across US and Canada, with supporting duties for the UK.
• Compliance & Policy: Maintain and evolve employee handbooks and HR policies to ensure strict compliance with federal and state/provincial laws (predominantly in the US).
• Onboarding & Lifecycle: Own the end-to-end onboarding process for new starters in the Chicago office and remote regions, ensuring a welcoming and professional "Mixam" introduction.
• HRIS Management: Act as the super-user for our HRIS (Rippling), ensuring 100% data integrity, accurate record-keeping, and efficient self-service workflows.
• Payroll & Benefits Support: Support with and partner with finance and external providers to support bi-weekly payroll inputs and manage US benefits administration.
• International Coordination: Liaise with our Employer of Record (EOR) partners for international regions (Europe/Philippines) to ensure global alignment.
• Culture & Communication: Act as a "people person" in the Chicago office, fostering strong relationships with our Customer Service, Care, and Supply Chain teams to drive engagement.

Qualifications and Experience required:

• HR Experience: Proven experience in an HR Advisor or Generalist role, ideally within a tech, eCommerce, or high-growth startup environment.
• Regional Knowledge: Strong expertise in US Employment Law is essential; experience with UK (CIPD standards), Canadian, or Australian labor practices is a significant advantage.
• Technical Skills: Proficient with HRIS platforms (experience with Rippling is a major plus) and standard office suites (Google Workspace/Microsoft Excel).
• Certifications: Professional HR certification: SHRM-CP/SCP or PHR/SPHR/ UK equivalent CIPD Level 5 or above.
• Communication: Impeccable verbal and written communication skills with the ability to navigate cross-cultural nuances effectively.
• Adaptability: Comfortable being a "team of one" locally while collaborating globally; ability to shift priorities quickly in a scaling business.
• People First: A genuine passion for supporting employees and managers with a pragmatic, solutions-oriented approach.
