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:
Copilot is our system for automating Design for Manufacturing (DFM) analysis and generating manufacturing processes. We work directly with some of the best operators in the world to identify high-impact opportunities to automate and augment with software.
Our team owns problems end-to-end: we design the software, define the manufacturing processes, and ensure they can be executed reliably in our factories. The work spans computational geometry, CAD/CAM integrations, high-performance systems, and full-stack web tooling. We execute whatever is required to deliver a working solution and best serve our users.
This role will focus heavily on computational geometry in the manufacturing context, while contributing across the broader stack. You will work closely with domain experts across machining, metrology, welding, additive, casting, forging, and more. You will have ample opportunity to learn from them and for them to learn from you. We believe there's no other way to solve these problems.
We're looking for people who can operate across boundaries, whether your background is in computational geometry, high-performance computing, or software engineering with strong mathematical intuition. Ultimately we care about building systems that have real impact in production environments.
What You'll Do

• Build systems that analyze CAD models to drive manufacturability decisions and generate real-world manufacturing processes
• Develop high-performance geometry and analysis pipelines in C++ and Python, including production GPU-accelerated workflows
• Integrate with CAD/CAM systems such as NX, hyperMILL, and other engineering tools
• Own system performance and reliability in production- testing, profiling, and continuously improving them
• Help expose internal capabilities through APIs and web-based tools that make them usable across the company
• Engage in process and product discovery alongside experts in manufacturing and software, working on ambiguous, real-world problems

What We're Looking For

• Bachelor's degree or higher in Computer Science, Mathematics, Physics, or a related field
• Strong programming skills in C++ and Python, with experience building and shipping production systems
• Experience with CAD systems or geometric modeling, including kernels like OpenCascade or Parasolid
• Experience with GPU-accelerated computing in production or performance-critical environments
• Comfortable working across the stack when needed, including developing and exposing systems via web services (gRPC, SQL, TypeScript, Docker, etc.)

What Will Set You Apart

• Experience in manufacturing environments and familiarity with industry CAD/CAM and simulation tools
• Experience with mechanical design and GD&T
• Clear communicator who can effectively explain complex technical problems to a wide audience
• Strong product intuition and pragmatic mindset-focused on solving high-impact problems for users and factories

Compensation
For this role, the target salary range is $130,000 - $250,000(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
