Senior TVC Actuation Engineer - Aerospace Mechanisms Lead

Castelion Corporation; Torrance (CA); On-site; USD 130,000 - 180,000; Full time

Job summary

Castelion Corporation is seeking a Senior Mechanisms Engineer to design and deliver thrust vector control actuation systems for long-range hypersonic strike vehicles. You will work hands-on with multidisciplinary teams to deliver TVC actuators and associated mechanisms in a fast-paced, hardware-driven environment.

The role requires deep experience with EMAs, high-load, high-bandwidth actuation, and integration with propulsion and control systems, within extreme environments.

Qualifications

• Bachelor’s, Master’s, or PhD in Mechanical Engineering or related field.
• 5+ years of experience in mechanism and actuator design for aerospace or high-performance dynamic systems.
• Experience with electromechanical actuators (EMAs), including motor-driven systems, gear reduction, and torque transmission.
• Familiarity with high-temperature materials, lubrication strategies, and extreme environments.

Responsibilities

• Design and develop TVC actuation systems, including actuators, linkages, mounts, and load paths for high-performance propulsion systems.
• Lead the architecture and detailed design of EMA systems, including gear trains, bearings, and structural components.
• Perform analysis of loads, stiffness, bandwidth, and dynamic response for precise thrust vectoring performance.
• Collaborate with propulsion, control electronics, GNC, and structures teams to ensure integration with vehicle architecture.
• Conduct tolerance analysis, lubrication strategy development, and life/reliability assessments for high-duty-cycle, high-load systems.
• Support prototyping, assembly, and hardware bring-up, including troubleshooting and root cause analysis.
• Define and execute qualification and environmental test plans, including vibration, thermal, and shock testing.
• Optimize designs for mass, stiffness, thermal robustness, reliability, and manufacturability.
• Mentor junior engineers and contribute to best practices in actuator and mechanism design.
• Partner with program leadership to make technical trades aligned with mission success.
