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.
The Role
The Manufacturing Engineer, Factory Construction is embedded in the field, driving construction execution with the rigor and ownership mindset of a manufacturing engineer - systematic, schedule-obsessed, and focused on outcomes. This role sits at the intersection of construction management and factory development, ensuring what gets built matches what production actually needs. This role requires a dynamic player who is constantly finding ways to make forward progress through uncertainty and take calculated risks. Ultimately, this role is partnering closely with engineering to intake requirements and translating them to a built reality - on schedule and in budget.
What You'll Do

• Field Execution & Contractor Oversight: Serve as the day-to-day owner's representative on active construction sites. Hold GCs and subcontractors accountable to schedule, quality, and sequencing. Identify and resolve issues before they escalate.

• Schedule & Problem Solving: Own near-term lookahead planning and critical path awareness. Apply first-principles thinking to recover lost time and protect delivery milestones.

• Requirements Partnership: Intake facility requirements by engineering, often driven by machine selection and operational flow. Drive engineering requirements or provide clear signal when they are blocking progress or pushing schedule. Push back on requirements that are driving unnecessary cost, complexity, or time to the construction project.

• Change Management & Documentation: Manage RFIs, submittals, pay applications, and change orders. Proficient in Procore for change order and drawing management, and Bluebeam for markups and document control.

• Design Feedback: Participate in design reviews for current and future phases. Translate field conditions into constructability and sequencing feedback before they become costly problems.

• Commissioning & Turnover: Sequence inspections, testing, and commissioning to avoid downstream delays. Support documentation and turnover packages for regulated manufacturing environments.

What We're Looking For

• Bachelor's degree in Engineering, Construction Management, or relevant STEM field - or 4+ years of hands-on field experience in lieu of degree.

• 2-4 years in construction management, capital project execution, manufacturing facilities development or equivalent project management experience.

• Direct field ownership of projects with GC or subcontractor oversight.

• Proficiency in Procore and Bluebeam.

• Willingness to travel up to 50%.

What Will Set You Apart

• Experience in regulated or high-consequence industries (nuclear, energy, aerospace, defense, advanced manufacturing).

• Background bridging construction execution and manufacturing operations.

• Familiarity with Lean construction or pull planning methodologies.

• Exposure to design-for-construction or design-for-operations efforts.

Compensation
For this role, the target salary range is $120,000 - $185,000(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
