• Coordinate complex domestic and international travel arrangements.
• Prepare polished executive presentations and create branded PowerPoint and Word templates.
• Process expense reports and manage office purchasing.
• Support cross-functional administrative needs as the company scales.

• Assist with employee onboarding, workspace setup, and new hire experience.
• Support HR processes including performance review cycles, interview scheduling, and training coordination.
• Help plan and execute trade shows, corporate events, and team-building activities.
• Contribute to shaping a positive, collaborative, and high-performance company culture.

What We’re Looking For:

• Bachelor’s degree and 4+ years of experience in office management or administrative roles (startup or tech environment preferred).
• Advanced proficiency in Microsoft Office Suite (PowerPoint, Excel, Word).
• Experience collaborating with international teams (U.S., Canada, Argentina preferred).
• Exceptional organizational skills and attention to detail.
• Ability to manage multiple priorities in a fast-paced, evolving environment.
• Self-starter mentality with strong problem-solving skills and a proactive approach.
• High emotional intelligence and a team-first mindset.

Why Join Celero?

• Be part of a high-growth semiconductor start-up at a pivotal stage.
• Make a visible, meaningful impact across the organization.
