About the Company
At AstroForge, our mission is to make space resources accessible on Earth. We mine asteroids to extract valuable minerals in space at a lower cost and smaller carbon footprint than current terrestrial mining methods. Along the way, we seek to leverage the technologies we build to provide additional value across other domains. We offer a unique opportunity to join an exciting team looking to expand humanity’s capabilities in space.
Job Description
As a Mechanical Engineer specializing in mechanisms at AstroForge, you will design, analyze, build, and test critical spacecraft mechanisms that must operate reliably in the harsh environment of space. This role emphasizes hands-on ownership of mechanism designs, from concept through qualification and flight, including deployment systems, actuation mechanisms, and precision moving assemblies.
Responsibilities
•
Design and develop spacecraft mechanisms, including deployment systems, actuation mechanisms, gimbals, and other precision moving assemblies.
•
Own mechanism designs end-to-end, from CAD and analysis through fabrication, integration, and testing.
•
Perform detailed mechanical analysis, including stress, fatigue, kinematics, and dynamics, to validate mechanism performance.
•
Conduct and support dynamics simulations and mechanism modeling.
•
Plan, execute, and analyze mechanism tests; use test results to iterate and improve designs.
•
Apply GD&T and tolerance analysis to ensure proper function and reliability of moving interfaces.
•
Collaborate with cross-functional teams to define requirements, interfaces, and verification plans.
•
Support material selection and manufacturing process development for mechanism components.
•
Document designs, analyses, test results, and lessons learned with full traceability to requirements.
Basic Qualifications
•
Bachelor’s degree in Mechanical Engineering or a related field.
