HR Generalist III

Playa Vista, California, United States

Turning Space into a Transportation Layer for Earth

Who We Are:

Eras of humanity can often be defined by a dominate transportation mode - horse drawn chariots, ocean going boats, or aircraft. These were spurred by a small group of people rigorously focused on building technology to achieve faster access to more of the world.  We seek to usher in a new era of humanity defined by universal access to the whole globe free of borders and the presence of a routine way from space to Earth. To do this, we are building highly maneuverable re-entry vehicles that can loiter in orbit before precision landing back on Earth. 

About the Role

As our HR Generalist, you’ll play a crucial role in developing and supporting our people operations from the ground up. You’ll be hands-on with the entire employee lifecycle—from onboarding and offboarding to employee relations, compliance, and engagement. You’ll work closely with engineering, operations, and leadership teams to ensure our workplace is compliant, inclusive, and high-performing.

This is a dynamic opportunity to build and scale foundational HR practices in a technically driven, fast-paced startup environment.

What You’ll Do

  • Own and refine onboarding and offboarding processes that are thoughtful, consistent, and tailored to both technical and non-technical roles.
  • Serve as a trusted partner in employee relations, ensuring team members feel heard, supported, and aligned with company values.
  • Maintain compliance with federal and state labor laws, including supporting our growing team.
  • Manage and maintain our HRIS and documentation, ensuring accuracy across employee records, offer letters, benefits, and more.
  • Partner with leadership on performance management, feedback cycles, and team communication tools.
  • Support initiatives that promote engagement, inclusion, and well-being—from surveys to culture-building events.
  • Collaborate with operations and engineering leads to ensure HR practices align with our technical workflows and workforce needs (e.g., shift work, secure facilities, contractor management).
  • Be a key player in shaping a values-driven, mission-aligned company culture.

Required Qualifications

  • Typically 5-8 years of experience in an HR Generalist, People Ops, or HR Business Partner role—ideally in a startup or technical environment.
  • Deep knowledge of employee relations, compliance, and HR fundamentals, with a hands-on mindset.
  • Strong organizational skills and attention to detail—you keep things on track, even in a fast-paced, high-change environment.
  • A warm, trustworthy presence and strong communication skills; you're a natural relationship-builder.
  • Familiarity with HR tools like Gusto, BambooHR, Rippling, or similar.
  • Experience in an aerospace or manufacturing environment. 

Preferred Qualifications

  • Experience supporting engineering or manufacturing teams, especially in high-security or ITAR-compliant settings.
  • HR certification (e.g., PHR, SHRM-CP).
  • Start-up experience highly preferred

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
