Senior Process Development Engineer Jobs in Los Angeles, CA

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.

Within Additive Manufacturing, you'll be the go to technical resource for process development, owning how we build, iterate, and automate the way we develop and mature our additive processes across various types of additive manufacturing. We're not approaching this the way additive has traditionally been done. We're rethinking it from the ground up, using automation, AI, and new software tools to move past the constraints that have limited additive. You'll be the process expert tying materials, process, and in process monitoring together, delivering the kind of innovative approach that lets us move quickly and work past the time constraints that have historically slowed this work down. This role is for someone ready to be challenged and take on highly technical work with the resources to push for innovation in additive manufacturing, helping build and refine the tools and processes that make our additive capabilities faster and more scalable over time.

The Role

• Lead process and parameter development for additive processes, with a primary focus on metals. Executing DOEs to define and measure process windows and drive machine, material, and process readiness.

• Drive adoption of in situ monitoring, statistical process control, and digital traceability records.

• Build software tools internally, or evaluate and implement existing tools on the market, to accelerate parameter development and process automation.

• Continuously research, evaluate, and bring in novel tools and technologies that support and strengthen process development capability.

• Design and build automated workflows and creative methods to efficiently validate and implement.

• Serve as the point of contact for developing specific parameter needs tied to unique part geometries or to overcome platform specific challenges.

• Work closely with the materials engineering team to roll out, validate, and implement new parameters and processes into production.

• Work cross functionally with applications engineers, materials engineers, systems engineers, software engineering, and welding engineers.

What We're Looking For

• Master's degree in an engineering discipline.

• 3+ years of experience developing and optimizing parameters and processes for additive manufacturing, with a strong focus on metal processes.

• Hands on experience with additive manufacturing equipment and software, including build processors or process simulation tools.

• Experience building or improving automated workflows, scripting, or tooling to speed up process or parameter development.

• Ability to work closely with materials engineering to translate new materials into validated, production ready processes.

• Comfort working in an undefined space, building new processes and tools rather than relying on established norms.

• U.S. Citizen or Permanent Resident (required for ITAR compliance).

What Will Set You Apart

• Extensive experience in LPBF as the primary process, with DED experience as a secondary strength.

• Background in aerospace, aviation, defense, energy, or similar industries with high specification requirements.

• Experience with in situ process monitoring and using that data to inform parameter development.

• Programming or scripting experience, such as Python, used to automate engineering workflows.

• Familiarity with industry specialized material standards, certification requirements, or quality systems such as NADCAP, AMS7000 series, AS9100, and relevant ASTM/AMS additive manufacturing specifications.

• Familiarity with fracture control classification of components and associated qualification requirements.

• Prior support of production scale up in high-rate manufacturing environments.
  

Compensation:

For this role, the target salary range is $135,000 - $200,000 (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.

• 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
