Original job description

About Us

Celero Communication Inc. is an ambitious semiconductor start-up building the technology that powers next-generation connectivity. We combine deep technical expertise with a bold, execution-driven mindset to solve complex challenges in high-speed communication and silicon innovation.

As a scaling company with a global footprint, we move fast, collaborate across borders, and value ownership at every level. Our culture is built on curiosity, accountability, and teamwork - where smart, driven people come together to turn breakthrough ideas into real-world impact.

We’re looking for a highly organized, proactive, and resourceful Office Manager & Administrative Coordinator who thrives in dynamic environments and wants to play a meaningful role in shaping both operations and culture from the ground up.

The Opportunity

This is more than an administrative role - it’s a mission-critical position at the center of our operations. You’ll be the operational heartbeat of our office, the go-to partner for leadership, and a key contributor to building an engaging employee and visitor experience.

If you love building structure where it’s needed, solving problems before they arise, and being part of a high-growth technology company, this role is for you.

What You’ll Do

Office Operations & Experience

Create and maintain a professional, welcoming office environment aligned with Celero’s brand and culture.
Coordinate customer visits, executive meetings, and company-wide events.
Manage day-to-day office logistics including supplies, equipment, and vendor relationships (facilities, furniture, refreshments, storage).
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.
