Description:

New Facility | Administration | Operations

Hyper Solutions is looking for an energetic, highly organized, and resourceful Senior Administrative Assistant to serve as an operational hub for our new facility.

This is more than a traditional office administrative position. It is a high-visibility opportunity to provide direct support to Hyper’s Co-Founder & CRO and President & COO while helping shape the employee experience and build the systems, culture, and workplace environment of a fast-growing technology manufacturer.

At Hyper, we’re looking for builders who bring energy, creative solutions, and a commitment to excellence. We move quickly, support one another, and believe that limits are for others. This role is well suited for someone who thrives in a dynamic environment, enjoys wearing multiple hats, and takes pride in bringing structure and organization to a fast-moving workplace.

As the face of our office and a trusted partner to company leadership, the Senior Administrative Assistant will balance executive support, office operations, workplace experience, event coordination, and administrative responsibilities that enable our teams to perform at their best.

Core Responsibilities

Provide administrative support to Hyper’s Co-Founder & CRO and President & COO, helping maximize their effectiveness and productivity.
Manage complex calendars, meetings, scheduling priorities, and executive commitments while adapting to changing business needs.
Coordinate domestic and international travel arrangements, itineraries, and related logistics.
Prepare and submit accurate and timely expense reports.
Draft, edit, proofread, and distribute professional business communications, presentations, correspondence, and reports.
Serve as a liaison between executives, employees, customers, and external partners.
Maintain confidentiality while exercising sound judgment and discretion when handling sensitive information.
Support special projects, cross-functional initiatives, and executive priorities as needed.

Additional Responsibilities

Create a welcoming, polished, and professional first impression for employees, visitors, customers, and partners.
Maintain an organized and presentation-ready reception area, conference rooms, kitchen, and common spaces.
Coordinate meeting logistics, including room reservations, catering, audio/visual setup, and guest accommodations.
Manage office supplies, inventory, shipping, mail distribution, and package handling.
Partner with property management and external vendors to coordinate facility maintenance, repairs, and workplace services.
Support company events, team meetings, all-hands gatherings, customer visits, employee celebrations, and engagement activities.
Build strong working relationships across all levels of the organization and help foster a collaborative, service-oriented workplace culture.
Identify opportunities to improve administrative processes, workplace efficiency, and the overall employee experience.
Serve as a trusted resource and ambassador for Hyper’s culture.

Requirements:

High school diploma, GED, or equivalent.
2+ years of experience in administrative support, office coordination, executive support, or a related role.
Exceptional organizational skills and strong attention to detail.
Ability to manage multiple priorities and changing demands in a fast-paced environment.
Strong verbal and written communication skills.
Professional presence with a natural hospitality and customer-service orientation.
Strong judgment, discretion, and ability to handle confidential information appropriately.
Self-motivated and comfortable working independently while collaborating across teams.
Proactive, solutions-oriented approach with the flexibility to assist wherever needed.
Proficiency with Microsoft Office Suite, including Outlook, Excel, Word, and PowerPoint.

Preferred Qualifications

Associate’s degree or higher.
5+ years of administrative or executive assistant experience in a fast-paced environment.
Experience supporting multiple leaders and managing complex calendars.
Experience coordinating meetings, events, and domestic or international travel.
Familiarity with video conferencing and collaboration platforms, including Microsoft Teams.
Strong business writing, proofreading, and presentation preparation skills.

What Success Looks Like

Hyper’s Co-Founder & CRO and President & COO receive organized, responsive, and reliable administrative support that allows them to focus on key business priorities.
Calendars, travel, meetings, expenses, and executive communications are managed accurately and efficiently.
Employees, customers, partners, and visitors consistently experience a welcoming and professional workplace.
The new facility remains organized, well-supported, and prepared for day-to-day operations, meetings, and company events.
Administrative and workplace processes become increasingly efficient as the facility and organization grow.
The role becomes a trusted resource for employees and leadership while contributing positively to Hyper’s culture and employee experience.

Why Hyper?

At Hyper, administrative professionals are viewed as strategic partners to the business, not simply support staff. This role offers direct collaboration with senior leadership, meaningful ownership, and the opportunity to influence how our new facility operates and evolves.

As a rapidly growing company, Hyper provides visibility, resources, and opportunities to support professional growth while giving employees the chance to help build something meaningful. You’ll work alongside a team that values initiative, problem-solving, collaboration, and a commitment to excellence. For someone who enjoys bringing order to complexity, solving problems, and creating an exceptional experience for employees and visitors, this role offers the opportunity to make an immediate and visible impact.

Location: Onsite in Anaheim, CA.

Compensation: The minimum anticipated hiring range is $75,000 - $85,000 per year. Actual salary varies based on factors including, but not limited to, relevant experience, skills, qualifications, and location. This hire will be eligible for discretionary bonus or incentive compensation. Variable compensation may depend on various factors, such as individual and organizational performance.

In addition to competitive compensation and comprehensive benefits including employer-paid medical, dental, and vision coverage, and a 401K with company match, Hyper offers growth opportunities and the ability to make an impact on the organization.

Hyper Solutions is an Equal Opportunity Employer.

We celebrate diversity and are committed to creating an inclusive environment for all employees. We do not discriminate based on race, color, religion, sex (including pregnancy, gender identity, and sexual orientation), national origin, age, disability, genetic information, veteran status, or any other protected status under applicable laws.
