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:

Hadrian is looking for a Software Engineer Intern to join the team building the software backbone of our autonomous factory. You'll work alongside experienced engineers on real production systems from internal tooling and data pipelines to the software that powers factory operations and customer-facing workflows. This is a hands-on role where your code will ship, and your contributions will directly impact how Hadrian scales.

What You’ll Do

• Build and improve internal tools, dashboards, and automation systems that support factory operations

• Contribute to backend services, APIs, and data pipelines used across engineering, operations, and quality teams

• Help design and implement features that improve visibility into production workflows, capacity, and program status

• Collaborate with cross-functional teams including operations, program management, and quality to understand requirements and deliver software solutions

• Write clean, well-tested code and participate in code reviews

• Surface technical risks and contribute to architectural discussions

What We’re Looking For

• Current university student pursuing a Bachelor's or Master's degree in Computer Science or a related field, with an expected graduation date between December 2027 and June 2028

• Proficiency in one or more programming languages (Python, TypeScript, Go, or similar)

• Familiarity with backend development, APIs, or data engineering

• Strong problem-solving skills and ability to work through ambiguous technical challenges

• Clear written and verbal communication

• Strong attention to detail and follow-through

• Excitement for manufacturing, aerospace, defense, or industrial systems

• Comfortable working in a fast-moving, highly ambiguous environment

• Willingness to work on-site in Los Angeles, CA

• Internships are available for our Fall 2026, Spring 2027, and Summer 2027 cohorts. Indicate your preferred term(s) when applying

What Will Set You Apart

• Prior internship or project experience shipping production software

• Interest in manufacturing systems, automation, or industrial software

What you’ll Gain

• Hands-on experience building software for a high-growth, mission-driven industrial company

• Direct involvement in real production systems, not just internal tools or side projects

• A front-row seat to how Hadrian is transforming aerospace and defense manufacturing through software, automation, and data
