Welder Helper Jobs in Santa Rosa, CA (NOW HIRING)

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

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.

As our People Systems Product Manager, you'll be the architect of our People technology stack - setting the roadmap, shaping how our platforms evolve, and making the configuration and integration decisions that determine how effectively our organization runs. You'll work closely with People, Finance, and IT leadership, translating business strategy into scalable systems and turning our people data into a reliable source of truth the business can act on.

You'll drive how we leverage Rippling across every module, define where automation can replace manual processes at scale, and build the governance frameworks that keep our data clean as we grow. You'll own the vendor relationships, scope the integrations, and set the standards.

We're looking for someone who thinks in systems, operates with a high degree of ownership, and gets excited by the leverage that comes from building infrastructure that scales. If you want to build something that outlasts you and shapes how a high-growth company operates at its core - this is the role.

What You’ll Do

• Own People systems end-to-end - serve as the internal product owner across all People systems and modules across our HRIS (Rippling), managing the roadmap, driving configuration decisions, and ensuring platforms scale with the business

• Audit where we're under-leveraging native capabilities, surface quick wins, and build out the automation workflows that eliminate manual People processes across onboarding, offboarding, approvals, and compliance

• Own our People data integrity - Build the processes and governance structures that keep our people data clean over time with repeatable standards that scale with the business

• Identify where native system capabilities end and integrations are needed, scope those requirements clearly, and manage any consultants or vendors brought in to execute

• Partner cross-functionally with People Operations, Recruiting, Finance, IT, and department heads to align on priorities, manage competing demands, and communicate tradeoffs in plain language

• Build and maintain foundational people reporting - establish the recurring reports and dashboards that give People and leadership a reliable, accurate view of the workforce

• Own and actively manage all people system vendor relationships - pushing forward our internal roadmap through platform enhancements and enablement

What We’re Looking For

• 6+ years owning or deeply administering an HRIS - Rippling experience strongly preferred; comparable platforms (Workday, BambooHR, HiBob) considered

• Hands-on experience building workflow automations within an HRIS - not just configuring fields, but designing logic, testing edge cases, and maintaining rules at scale

• A track record of owning data quality in a fast-moving environment - you've cleaned up a messy system and built processes to keep it clean

• Translate business requirements - you translate complex People and business needs into clear system configuration and custom solutions

• Process analysis and design - you map, document, and optimize People workflows (onboarding, payroll, performance management, etc.) and create supporting SOPs

• Experience scoping integration requirements - you know enough to write a clear brief, manage a vendor, and QA the output, even if you didn't build the pipelines yourself

• Strong analytical instincts - you define what a dashboard needs to answer before you build it, and you catch data problems before they become leadership problems

• A bias toward action and ownership - comfortable operating independently in a hyper-growth startup environment

What Will Set You Apart

• Direct Rippling implementation or re-implementation experience at a scaling company

  Exposure to people analytics tools (ChartHop, Visier) or BI tools (Tableau, Looker, Power BI)

• Familiarity with APIs or data pipelines to scope engineering work and validate delivery

• Experience building a people systems function during a high-growth period

• Experience supporting both exempt and non-exempt populations in manufacturing, defense, or similarly complex environments

Compensation

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.
