Operations Administrator; CEO - Part-Time | Hybrid

Pioneer Power Group, a trusted leader in power system studies, is seeking a detail-oriented and highly organized Operations Administrator to support our CEO and help keep our growing organization running smoothly.

This is a dynamic, fast-paced role in a scaling company where priorities shift, and no two weeks look exactly the same. The right candidate is proactive, resourceful, and comfortable, owning a wide range of administrative and people operations responsibilities with precision and professionalism.

This is a hybrid role based in Rockville, MD
, requiring onsite presence 2–4 days per week (flexible for the right candidate).

This role is part-time, with flexible weekly hours. We are open to structuring the schedule based on the right candidate’s availability and the needs of the business.

• This is a high-visibility role reporting directly to the CEO. We seek a very strong point-person with a “can-do” attitude.
• The work is varied and hands-on
  ; the ideal candidate enjoys switching between people operations, administrative problem-solving, and operational support
• We are one of the fastest growing companies in the nation, and as a small, growing organization (~40 employees), we need people who are detail and speed oriented while taking ownership of work assignments.
• Prior experience in a startup or emerging company environment is strongly preferred

• Own day-to-day people operations and administrative support, including following up on open items or directives from CEO and VP which includes track/manage/follow-up on tasks to ensure completeness.
• Handle state and compliance-related administrative tasks, including state tax portals, registrations, credential organization, and address or withholding updates
• Act as a go-to problem solver for operational issues (e.g., payroll, banking, or international wire issues), coordinating with vendors and support teams through resolution
• Maintain accurate, well-organized employee records (addresses, state tax setup, PTO/vacation tracking, compensation updates, required forms), with a high level of confidentiality and attention to detail
• Own end-to-end onboarding administration for new hires, including offer letters, system setup, and onboarding checklists
• Provide light finance and operations support, such as sending occasional invoice nudges, organizing receipts, and collecting documentation for accountants and bookkeepers
• Keep internal systems, documentation, and processes organized, current, and scalable as the company grows

• Bachelor’s degree or equivalent experience, with 5+ years of experience in broad-based administrative, office management, or people operations roles
• High integrity, discretion, and calm judgment when handling sensitive information
• A natural love of checklists, tracking, and closing loops – nothing falls through the cracks
• Strong follow-up instincts
  : you proactively track open items, follow up with internal stakeholders, and relieve the CEO from having to check in on status
• The ability to comfortably manage 10–20 moving tasks at once without losing momentum
• A proactive mindset – you flag issues early and propose practical solutions
• Exceptional attention to detail (you notice a $0.07 discrepancy instinctively)
• Comfort working across systems and portals such as Paychex (or similar), Deel, and customer invoice portals
• Strong spreadsheet skills (Excel / Google Sheets) for trackers, reconciliations, and documentation
• Polished,
  professional communication with vendors, customers, and support teams

We are looking for someone who will own administrative and people operations functions so the CEO can focus on strategic priorities. This role is ideal for a proactive self-starter who enjoys bringing order, anticipating needs, and making things run better.

If you’re excited to make a measurable impact, enjoy being trusted with real responsibility, and want your work and ideas to be valued, we would love to hear from you.
