Ehs Engineer Jobs in California (NOW HIRING)

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're accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.
Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.
The Role
We are seeking an EHS Engineer to support safety operations embedded within our special projects research and development teams at Hadrian. This role is central to building safe, scalable processes around novel and emerging manufacturing technologies, from advanced welding and additive manufacturing to casting, forging,
and general fabrication.
At Hadrian, we are building a culture where zero incidents is the standard, and every team member plays a role in preventing harm through ownership, participation, and continuous improvement. As the EHS Engineer, you will serve as the primary EHS partner to special projects and process development teams, working proactively to identify hazards in new and evolving processes before they reach the production floor. You will develop controls, write procedures, and engage directly with engineers and technicians to ensure that safety is designed in from the start.
This role is best suited for someone who is technically curious, hands-on, and comfortable operating at the intersection of engineering and safety. You should be energized by novel process challenges, able to assess risk in ambiguous environments, and skilled at translating complex hazard profiles into clear, practical controls
that teams will actually use.
What You'll Do
You will serve as the primary EHS resource for Hadrian Factory X and our process development teams, providing proactive EHS support from early-stage experimentation through process scale-up. Key functions will include:

• Identify and assess hazards associated with new and emerging manufacturing processes including MIG, TIG, and laser welding, additive manufacturing, casting, forging, and general fabrication
• Develop and implement engineering controls, administrative procedures, and PPE programs tailored to the specific hazard profiles of each process
• Partner with R&D engineers and technicians to integrate safety by design into new process development workflows and equipment commissioning
• Lead or support incident reporting, investigation, and corrective action for safety incidents
• Author and maintain safety procedures, standard operating procedures (SOPs), and risk assessments for all R&D processes
• Conduct and document hazard assessments (Haz-ops, JHAs, RAs) for new equipment and processes prior to operation
• Support and deliver safety training to staff on process-specific hazards and controls
• Provide field-driven feedback to improve EHS program usability and effectiveness across the company
• Ensure compliance with OSHA, ADEQ, and applicable local requirements, including standards relevant to welding, additive manufacturing, metal casting and forging, and industrial fabrication
• Serve as a technical resource for regulatory inspections and agency interactions related to R&D processes

What We're Looking For

• 5-10 years of EHS experience in manufacturing, fabrication, or industrial environments
• Working knowledge of OSHA, EPA, California, and local regulatory requirements
• Technical knowledge of hazards associated with welding (MIG, TIG, laser), metal additive manufacturing, casting, forging, and fabrication processes
• Strong communication and interpersonal skills, with the ability to influence across all levels of the organization
• Ability to assess risk in ambiguous, fast-moving environments where standard procedures may not yet exist
• Demonstrated experience implementing EHS programs and engaging cross-functional teams

What Will Set You Apart

• Professional certifications such as CSP, CIH, or equivalent
• Bachelor's degree in EHS, Engineering, or related field (or equivalent experience)
• Experience in high-tech manufacturing environments (automation, robotics, machining)
• Direct experience with laser safety programs and laser classification/controls
• Familiarity with metal powder handling safety, inert atmosphere systems, and additive manufacturing post-processing hazards
• Experience building or improving EHS systems in a startup or scaling environment

Compensation
For this role, the target salary range is $120,000- $160,000(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 for Full-time Employees

• Medical, dental, vision, and life insurance plans for employees
• 401k
• Relocation support may be provided for certain situations, based on business need.
• Flexible vacation policy
• Equity
