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

Candidates for this role could end up working with several of our internal products and teams:

Flow is Hadrian’s FactoryOS, our core platform comprised of applications that model, manage, and automate an extremely complex network of factories.

Copilot is our suite of manufacturing automation products that automates or accelerates key processes within the factory including quoting, CAM programming, and CMM programming.

Factory Automation develops robotic cells for use in our factories and the software that controls them.

We have a broad set of backend services and applications internally. Candidates interested in redefining manufacturing software—from distributed systems to automation infrastructure—will have ample opportunity to do so.

What You’ll Do

• Scope, architect, implement, and deploy critical backend services across multiple product verticals.

• Design and maintain reliable, scalable, and high-performance APIs and systems in a complex production environment.

• Engage in product discovery alongside experts in manufacturing and software—help define what needs to exist and what needs to be better.

• Build alongside an incredible team of engineers and operators.

What We’re Looking For

• Expertise in modern backend technologies, with a deep understanding of distributed systems, service architecture, data modeling, and scalable infrastructure design.

• Strong ability and desire to write high-quality, maintainable code.

• Experience designing and implementing APIs (REST & gRPC).

• Know how to develop, deploy, and maintain backend and full-stack applications using a modern cloud or containerized stack.

• Bias toward action and take pride in your work.

• Excited to work in a fast-paced environment with high stakes and quick iteration cycles.

What Will Set You Apart

• Strong product intuition and user empathy. You enjoy understanding how your services impact real operators and workflows.

• Experience working across multiple languages or systems as needed: Go, Python, C#, C++, etc.

• Background with systems that require high performance, reliability, or real-time processing.

• Familiarity with CAD/CAM software, robotics, automation, manufacturing systems, or 3D environments.

• Demonstrated success implementing and scaling production systems in complex environments.

Compensation

For this role, the target salary range is $120,000- $300,000 (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
