About Union

Union is a 3 person team that delivers People Operations and Recruiting expertise and services for high-retention startups. We work with our clients to build or upgrade any process, tools, and performance management policies necessary so our candidates, and everyone our clients hire, succeed long-term.

About the Role:

We are seeking a highly organized and detail-oriented HR professional to support our 10+ client’s operations. Most of our clients are 10-60 person startups and SMBs in the US with some international teams.

The ideal candidate will have 4-10 years of experience in human resources, a strong command of English, and the ability and detail-orientation to manage a diverse range of administrative HR tasks. Over time, we expect you to contribute to the firm’s internal operations.

This role offers an exciting opportunity to work in a fast-paced environment while contributing to the efficient functioning of a growing organization.

Key Responsibilities:

  • Admin & Payroll: Run payroll, make changes to pay, and ensure accurate processing of I-9s and E-verify.

  • Onboarding: Handle the onboarding process for new hires, including document preparation and coordination of logistics such as booking hotels.

  • Communication: Draft and send communications to team members, executives, and the CEO, ensuring clarity and professionalism.

  • Sourcing and Recruiting Coordination: Depending on needs of business, you may also help a Recruiter.

  • Process Improvement: Use a process-oriented mindset to streamline workflows and improve efficiency, including quality assurance of HR materials (e.g., formatting of decks).

Ideal Candidate Profile:

  • Experience: Diverse or in-depth HR experience, with a background in handling administrative tasks, payroll, and employee relations. A person not too senior to avoid boredom with detailed work but experienced enough to navigate complex HR processes. Someone who has worked for a consultancy, smaller US businesses managing HR, or who owned a diverse set of tools at a lager company would be ideal.

  • Knowing startups is great but not necessary, except writing style cannot be "too formal" or "corporate"

  • Strong proficiency in English (both written and verbal) for communication with employees, executives, and the CEO.

  • High attention to detail, ensuring no errors in formatting and employee communications.

  • Experience with HR tools such as Rippling, Justworks, and BambooHR.

  • Ability to write job descriptions and review communications for clarity.

  • Must be content with administrative tasks and able to manage multiple responsibilities efficiently.

Compensation and Benefits:

  • $24,000-$48,000 a year, contracting

  • Unlimited PTO

  • Macbook Air provided
