• Ensure smooth operations so teams can focus on innovation and execution. 

Executive & Administrative Support 

• 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. 

People & Culture Support 

• Assist with employee onboarding, workspace setup, and new hire experience. 

• Support HR processes including 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). 

• HR Experience is preferred but not required. 

• 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. 

• Gain exposure to operations, HR, executive support, and corporate events. 

• Work with a collaborative, global team that values initiative and innovation. 

• Grow your career as we scale and redefine what’s possible in connectivity technology.
