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.\nFollowing 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.\nBacked 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.\nIf 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.\nThe Role:\nHadrian's welding team is building out our weld development center and is looking for dedicated mechanical engineering support. As an R&D Engineer supporting welding, you'll work side by side with welding engineers and welders in a development environment to design tooling, parts/coupons, and fixtures, support equipment buys and setup, and close the gap between weld development and production. This is a hands-on, in-person role split between design and the shop floor, not a design-desk-only position.\nWhat You’ll Do\nSupport welding equipment needs for weld development, including CAD support for buying and setting up new equipment\n\nDevelop concepts for automation, tooling, fixtures, and development parts\n\nWork directly with welding engineers and welders to weld actual parts in a development setting\n\nBridge the gap between automation, tooling, and welding by translating development needs into tooled-up, automatable processes\n\nCoordinate across Build, Software, Tooling, Automation, and NDT to keep weld development unblocked\n\nWhat We’re Looking For\nBachelor's degree in Mechanical Engineering, Welding Engineering, Industrial Engineering, or a related field\n\n2+ years of experience in manufacturing or mechanical design\n\nProficiency in CAD (SolidWorks, NX, or equivalent) and working knowledge of GD&T and tolerance analysis\n\nComfort with shop-floor tooling, fixtures, and metrology\n\nExposure to machining, assembly, welding, additive, and inspection processes\n\nWhat Will Set You Apart\nPrior hands-on welding or weld process experience\n\nExperience designing tooling or fixtures for automated or robotic welding cells\n\nFamiliarity with manufacturing processes and requirements\n\nA track record of thriving in an undefined, first-of-its-kind role\n\nBenefits for Full-time Employees\nMedical, dental, vision, and life insurance plans for employees 401k\n\nRelocation support may be provided for certain situations, based on business need.\n\nFlexible vacation policy\n\nEquity\n\nITAR Requirements\nTo conform to U.S. Government export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen or national, lawful permanent resident, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.\nUse of AI in hiring\nHadrian uses AI-assisted tools in our recruiting and hiring processes to help our team work more efficiently. This may include tools that help organize and analyze recruiting data, as well as an AI-powered notetaker that can record and transcribe interviews and help coordinate feedback. These tools support our team and are not used to make hiring decisions. All candidate evaluations and hiring decisions are performed by humans. If an interview will be recorded, you will be notified in advance and may opt out at any time with no impact on your candidacy. Candidate data processed through these tools is subject to the same protections described in our Privacy Policy.\nConsideration of Criminal History\nHadrian will consider for employment qualified applicants with criminal histories in a manner consistent with the requirements of all applicable laws. We do not ask about criminal history on our application, and we do not consider criminal history before making a conditional offer of employment.\nHadrian Is An Equal Opportunity Employer\nHadrian does not unlawfully discriminate on the basis of race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, marital status, mental status, physical disability or any other legally protected status.
