Trusted Tech Inc

Who We Are:

TrustedTech is a leading Microsoft Cloud Solution Provider (CSP) specializing in Microsoft Cloud services, Microsoft perpetual licensing, and Microsoft Support Services for medium and enterprise-sized businesses. Our robust team of in-house, U.S-based Microsoft architects and engineers are certified in all 6/6 Microsoft Solutions Partner Designations in the Microsoft Cloud Partner Program.

Prioritizing a people-centric mission, TrustedTech has transformed the Microsoft software licensing experience, giving IT professionals complete confidence in the success of their Microsoft investment.

Overview:

TrustedTech is seeking a polished, highly organized, and people-oriented Office Administrator to join our team. This is a visible, high-impact role at the center of TrustedTechs day-to-day office experience, serving as the face of the Irvine office for guests and vendors, and partnering closely with the People & Talent team on HR administrative support to deliver a standout employee experience.

This role is as much about presence and professionalism as it is about logistics. The right person brings genuine warmth, sharp organizational instincts, and the ability to manage competing priorities across office operations, vendor and client coordination, and HR administrative support, without missing a beat.

Responsibilities:

Office Operations, Vendor & Client Management

  • Serve as the primary point of contact for office vendors, managing day-to-day vendor relationships, ordering, and service coordination.
  • Serve as the primary point of contact for all office visitors, greeting guests warmly and creating a professional first impression.
  • Manage conference room setup and breakdown for meetings, handle incoming/outgoing mail, and maintain general office organization.
  • Monitor, order, and restock office supplies, kitchen snacks, and beverages to ensure the environment is well-equipped.
  • Coordinate on-site perks programs, such as the office car wash and other employee-facing amenities.

HR Administrative Support

  • Oversee the sourcing, ordering, and distribution of client/employee gifts, including managing digital gifting platforms like Prezzee.
  • Coordinate employee gifting and recognition logistics, including birthdays, work anniversaries, and other milestones.
  • Support offboarding logistics, including equipment return and coordinating badge/access removal with the appropriate teams.
  • Assist with internal HR communications, including distributing announcements and reminders for surveys, engagements, and other People & Talent initiatives.
  • Provide general administrative support to the People & Talent team, including scheduling and document preparation.

Culture, Events & Employee Experience

  • Partner with the People & Talent team on new hire logistics, including desk setup, technology prep, and welcome packages.
  • Plan and coordinate team-building activities for the office.
  • Provide hands-on support for large-scale quarterly corporate events, from planning through on-the-day execution.
  • Coordinate logistics for events supporting the UK team, partnering with international stakeholders and accommodating time zone differences as needed.
  • Maintain a proactive, solutions-first approach to the needs of the team to foster a positive office culture.

Required Skills & Qualifications (must-haves):

  • 2+ years of experience in office administration, HR administrative support, front desk operations, or a closely related administrative support role.
  • Exceptional organizational and multitasking skills, with a demonstrated ability to manage competing priorities, track multiple moving parts, and maintain sharp attention to detail in a fast-paced environment.
  • Outstanding verbal and written communication skills, with professionalism to interact confidently with employees, office visitors, clients, and external vendors.
  • High degree of reliability, punctuality, and discretion, particularly when handling confidential employee information and HR administrative records.
  • A warm, service-oriented approach to the office environment, with genuine enthusiasm for creating a positive experience for employees and guests alike.

Preferred Skills & Qualifications (nice-to-haves):

  • 2+ years of experience in office administration, customer service, front desk/reception, or a closely related administrative support role.
  • Proficiency with Microsoft Office Suite (Outlook, Word, Excel, Teams) and/or Google Workspace (Gmail, Calendar, Docs), including the ability to manage complex calendar coordination across platforms.
  • Experience with Prezzee or similar corporate digital gifting platforms for employee and client recognition programs.
  • Prior experience working closely with an HR or People & Talent team, supporting onboarding, culture programming, or employee experience initiatives.
  • Experience coordinating corporate events or off-site team activities, including vendor management, logistics planning, and on-the-day execution support.
  • Familiarity with a technology company or professional services environment, where pace, professionalism, and adaptability are part of the daily culture.

Working Environment & Hours:

  • Type: Onsite at Irvine HQ (UCI Research Park), Monday Friday
  • Hours: 6:00 am to 3:00 pm (*with flexibility to work after hours as needed for occasional quarterly events and UK team coordination)
  • Overtime: This is a non-exempt position; overtime may be required at times, and any overtime worked is eligible for overtime pay in accordance with applicable federal and California law.
  • Compensation (non-exempt/hourly role) : $75K annually ($36.06/hr)

Benefits:

- 100% employer-paid base medical coverage: HMO (CA) | PPO (out-of-state)

- Dental and vision coverage

- 401(k) with 4% company match (fully vested)

- Paid vacation, sick leave, and holidays

- Paid parental leave

- Voluntary benefits (STD*, life/AD&D, accident, critical illness, hospital)

- Employee Assistance Program (EAP)

- Pet discount plans

- Microsoft reimbursement program

(*Short-term Disability available for employees outside California)
