Chief Operating Officer (COO)

The COO will be the guardian of our culture.
We are looking for a people-first leader – someone who lives the culture, embodies it every day, and inspires others to follow. This is not a back-office role. The COO will be the face of how we work, the advocate for our values, and the driving force behind building an environment where people grow, stay accountable, and perform at their best.

  • Irvine, CA / USA
  • Remote / Worldwide

Key Responsibilities

  • Lead and inspire teams by setting the standard for culture and performance.
  • Build and strengthen organizational culture as its main advocate and role model.
  • Create scalable operational processes that support growth.
  • Drive accountability and results across all teams.
  • Work closely with the CEO on strategy and long-term planning.
  • Anticipate future challenges and prepare the company for the next 2–3 years.

Requirements

  • Minimum 2 years in a senior operational role (COO, Operations Director, or similar).
  • Proven experience scaling a tech or service company.
  • Strong leadership presence – people trust you and follow your lead.
  • Ability to balance hard execution with genuine care for people.

What we offer

  • A leadership role with direct influence on the company’s future.
  • Opportunity to shape both operations and culture at an international scale.
  • Equity discussions possible for the right candidate.
