Hadrian - Manufacturing the Future

Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.

We recently raised $260 million dollar Series C to accelerate this mission. We are excited to be launching a new Factory in Mesa, Arizona, a 270,000 square foot facility that will create 350 new jobs immediately. We are opening a new headquarters to support thousands of future hires, launching Hadrian Maritime to serve naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.

Hadrian works with startups, Tier 1 and Tier 2 suppliers, and major defense contractors across space, shipbuilding, and aviation to scale production, reduce costs, and accelerate delivery on mission‑critical programs. We are backed by leading investors including Lux Capital, Founders Fund, and Andreessen Horowitz. Our fast‑growing team is united by a shared mission to reindustrialize American manufacturing for the 21st century and beyond!

At Hadrian, we’re not just building autonomous factories – we’re building the teams, systems, and culture that will power the future of aerospace and defense manufacturing . As we scale, the People team plays a critical role in shaping how we attract, enable, and retain world‑class talent across both engineering and advanced manufacturing . Working on the People team at Hadrian means designing and operationalizing the foundation of a company that blends cutting‑edge robotics, AI, and precision manufacturing – while supporting a workforce that spans software engineers, machinists, program managers, and everything in between .

We’re looking for builders: thoughtful, action‑oriented team members who care deeply about people, process, and performance – and who want to help create a company culture that’s as strong as the infrastructure we’re deploying. If you’re energized by complexity, mission‑critical work, and the chance to shape the trajectory of a generational company from the inside out, we’d love to hear from you.

We are looking for a People Operations Generalist who can be a dependable go‑to person for day‑to‑day HR operations in a hyper‑growth environment. In this role, you will support a positive, high‑speed employee experience by ensuring that our people processes run smoothly across the entire employee lifecycle. You’ll work closely with the broader People Ops team to administer onboarding/offboarding, maintain data and systems, and support employees and managers with HR‑related needs – all while helping build a strong, scalable foundation for our growing team.

• Manage and execute daily HR operations, including coordinating onboarding and offboarding logistics, processing employee status changes, and administering leave of absence processes. You’ll use our HRIS (Rippling) and other tools to ensure employee data is accurate and all processes are completed in a timely manner.
• Serve as a primary point of contact for employees and managers on routine HR questions or issues, providing prompt, thoughtful support and guiding them through policies and self‑service resources.
• Maintain our People systems and data with a high degree of accuracy – from ensuring HRIS records and org charts are up‑to‑date, to troubleshooting minor system or access issues for team members. You will suggest and implement improvements to keep our People tech stack efficient and user‑friendly.
• Ensure compliance and consistency in HR administration: help prepare documentation for audits, manage personnel files and HR records, and enforce standard operating procedures for tasks like I‑9 verification and background checks.
• Coordinate cross‑functionally to deliver a seamless employee experience. For example, you’ll partner with IT to make sure new hires have the equipment and access they need on Day 1, and with Finance to communicate payroll changes or verify data for reporting.
