About Mesa Quantum
Mesa Quantum is building the next generation of quantum sensing and Position, Navigation, and Timing (PNT) technologies. Our mission is to make quantum technologies practical, scalable, and deployable in real-world applications spanning defense, critical infrastructure, telecommunications, and autonomous systems. We are a fast-growing deep-tech startup backed by leading investors, government partners, and industry stakeholders.

As we continue to scale, we are looking for a highly organized and proactive People & Operations Coordinator to help keep the company running smoothly. You'll own HR and People Operations end-to-end, from offer letter to offboarding, while also standing up the processes, systems, and documentation. You'll be the go-to person for employees and leadership alike, and you'll pick up adjacent operational work (procurement, vendor management, facilities) when the business needs it. leadership has accurate people data whenever they need it; and HR never becomes the bottleneck as we grow.

What You'll Own  People Operations
~ Performance management processes and employee relations support
Company policies, employee handbook, and compliance across our operating jurisdictions
Design and document scalable HR workflows: you're not just running a playbook, you're writing it
Own the HRIS and keep employee data clean and current
Payroll coordination and benefits administration
Operations (as needed)
Procurement, vendor management, and software license/subscription tracking
Facilities and workplace operations
General administrative support for leadership initiatives
5+ years in HR/People Ops with real ownership of core responsibilities, not just administrative support
~ A track record of building HR processes from scratch, not just executing existing ones
~ Strong grasp of employee lifecycle management, compliance basics, and confidentiality norms
~ Comfort with ambiguity and a genuine willingness to be hands-on outside "traditional HR" when needed
~ Multi-state HR experience, payroll/benefits administration, HRIS/ATS platforms
Experience with vendor, procurement, or facilities management
HR-related degree or equivalent experience
Low ego, adaptable, and willing to help wherever needed.

Takes pride in helping teams and organizations operate effectively. You'd be the first real owner of HR at Mesa, building the systems and practices that shape how we hire, support, and retain people as we scale.
