Full Time Additive Manufacturing Engineer Jobs in California

Hadrian - Manufacturing the Future
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.
We're looking for a hands-on systems engineer who can take metal additive manufacturing equipment from standalone machines to fully integrated, automated production systems. This is the hands-on AM technical authority on the team. You will lead the commissioning, qualification, and production readiness of all PBF-LB systems executing FAT, SAT, IQ, and OQ protocols against the Hadrian standard, owning machine-level reliability programs, and serving as technical interface to OEM field engineers. You will also own cell-level P&IDs and support automation integration, ensuring every machine is production-ready by end of year.
RESPONSIBILITIES:

• Systems Integration and OPUS Enablement: Execute the end-to-end integration of metal AM machines, peripherals, and cell infrastructure into OPUS, Lead FAT and SAT for all incoming PBF-LB systems against Hadrian acceptance criteria - coordinating OEM field engineers, documenting results, and driving resolution of open items to production release.
• Integration Architecture and Standards: Define system requirements, interface control documents (ICDs), integration kits, and machine acceptance criteria that scale across multiple OEMs, configurations, and sites.
• Commissioning, FAT/SAT, and Qualification Support: Build and own factory acceptance test (FAT) and site acceptance test (SAT) playbooks, commissioning checklists, and validation plans. Partner with Quality and Process teams to ensure integrated systems support qualification and production release.
• Reliability, Maintainability, and Uptime: Experience reliability engineering discipline for AM equipment (PM strategy, spares, calibration, MTBF and MTTR tracking, failure mode mitigation). Ability to structured root cause and corrective action with OEMs and internal teams.
• Machine Modification and Performance Upgrades: Lead efforts to implement hardware, firmware, and configuration improvements that increase build envelope utilization, process stability, and throughput (for example gas flow, recoater systems, calibration, and motion subsystems), while maintaining configuration control.
• Manufacturing Controls and Documentation: Own standard work for machine operation and integration points, including equipment control procedures, safety interlocks, change control, and training. Ensure readiness for regulated environments and customer audits.
• Cross-Functional Execution: Partner tightly with Additive Manufacturing, Materials and Process, Manufacturing Engineering, Software, Quality, Supply Chain, and Operations to industrialize solutions and deliver production commitments.

PREFERRED QUALIFICATIONS AND SKILLS:

• Bachelor degree in Mechanical Engineering, Materials Engineering, Manufacturing Engineering, or related field Master's degree is a plus.
• 5+ years of experience in metal additive manufacturing systems engineering, equipment engineering, automation, or factory-scale integration, with deep familiarity in metal LPBF.
• Hands-on knowledge of metal LPBF machine architecture and key subsystems including powder handling, optics, motion, recoater, build plate handling, atmospheres and gas flow, sensing and monitoring, and post-build workflow.
• Experience reading, redlining, and maintaining P&IDs for process utility systems in a manufacturing environment

• Familiarity with reliability engineering fundamentals - PM program design, MTBF/MTTR analysis, and structured problem-solving
• Experience managing OEM relationships and coordinating commissioning across multiple machine platforms
• Experience deploying automation in production manufacturing environments, including safety, interlocks, commissioning, and sustaining engineering.
• Strong problem-solving using structured methods (8D, 5 Whys, fishbone) and proven ability to drive corrective and preventive actions to closure.
• Willing to travel up to 20%, including international supplier visits.; U.S. Citizen or Permanent Resident (required for ITAR compliance).

COMPENSATION:
For this role, the target salary range is $150,000 - $220,000(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.
