Job description

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.

For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.

Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.

We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

• Work with manufacturing and suppliers to resolve hardware and production issues.

Requirements

• U.S. Person status is required as this position needs to access export controlled data.
• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 3+ years of experience designing and developing mechanical hardware.
• Proficiency in CAD software (e.g., NX, SolidWorks).
• Strong understanding of mechanical design fundamentals, GD&T, and tolerance analysis.
• Strong hands‑on problem‑solving skills and ability to work in a fast‑paced environment.

Preferred Qualifications

• Experience designing deployment, articulation, or electromechanical mechanisms for spacecraft, aerospace, robotics, or similar systems.
