Job Description
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!
The Role
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 seeking a detail-oriented and systems-savvy HR Systems Administrator to support the design, optimization, and day-to-day administration of our core HR systems, including Rippling, Ashby and Lattice. In this role, you'll act as a critical operational partner to the People team, ensuring the integrity of our data, reporting accuracy, and the efficiency of our People processes at scale.
This role is ideal for someone who is both technically capable and deeply user-focused, with a strong understanding of HR system workflows and compliance considerations in a high-integrity, hyper-growth and complex environment.
What You’ll Do
Administer and maintain HR systems including Rippling, Ashby and Lattice, as well as future LMS and compensation platforms
Manage system configuration, upgrades, and user permissions while ensuring data integrity and security
Develop and maintain system documentation and SOPs
Act as a technical resource and liaison between HR, IT, Finance, and external vendors
Support employee lifecycle processes through workflow optimization and automation
Build and deliver standardized and ad hoc reports for People analytics, compliance, and audits
Partner with HR stakeholders to improve system workflows, user experience, and data accuracy
Lead or support implementations of new HR technologies or system enhancements
Ensure compliance with data privacy standards and regulatory requirements (e.g., ITAR, SOC 2)
What We’re Looking For
3+ years of relevant industry experience.
Strong execution mindset. Resourceful and thoughtful about how to leverage the support around you to get things done quickly.
Ability to see how individual pieces impact the larger infrastructure and processes.
Relentless focus on accurate data entry, auditing, and clean reporting.
Excels at working on open-ended problems and running them down to completion.
Comfortable working cross-functionally and providing user support and training.
Trusted with sensitive information and comfortable operating in a compliance-heavy environment
What Will Set You Apart
Proven experience with Rippling, Ashby, Lattice, and other HR tools
Strong project management skills and ability to prioritize in a fast-paced environment
Intermediate to advanced proficiency in Excel or SQL for data analysis
Familiarity with integrations between HR systems and payroll, finance, or IT platforms
Effective communicator who can translate technical concepts for non-technical stakeholders
Analytical mindset with a strong eye for process improvement
Experience with ITAR- or DFARS-compliant data systems is a plus
Compensation
For this role, the target salary range is $90,000 - $150,000 (actual range may vary based on experience).
This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee’s pay position within the salary range will be based on several factors including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs.
Benefits
100% coverage of medical, dental, vision, and life insurance plans for employees
401k
Relocation stipend if you’re moving from outside of LA
Flexible vacation policy
