Senior Mechanisms Engineer - Aerospace Actuation

Castelion Corporation; Torrance (CA); Híbrido; USD 120.000 - 180.000; Jornada completa

Descripción de la vacante

Castelion seeks a Senior Mechanisms Engineer to design and deliver high-performance mechanical actuation for long-range hypersonic strike vehicles. You will lead gear trains, elevon drive shafts, and control surface mechanisms, ensuring reliable operation in extreme flight conditions.

Join a fast-paced, hardware-driven team that collaborates with control electronics, GNC, avionics, and structures engineers to validate mechanisms through analysis, testing, and iterative prototyping.

Formación

• Bachelor's, Master’s, or PhD in Mechanical Engineering or related field.
• 5+ years of experience in mechanism design, analysis, and validation for aerospace or high-performance mechanical systems.
• Strong background in gear trains, actuation systems, and precision mechanical design.
• Experience designing electromechanical actuators (EMAs) for aerospace or similarly demanding applications.
• Familiarity with motor-driven actuation systems, including motor selection, gear reduction, torque transmission, and position feedback mechanisms.
• Proficiency in CAD and analysis tools (NX, SolidWorks, ANSYS, or equivalent).
• Experience with structural analysis, fatigue/life assessment, and tolerance stack-up analysis.
• Familiarity with high-temperature materials, lubrication strategies, and operation in extreme environments.
• Experience with hardware build, test, and troubleshooting in a lab or flight hardware environment.
• Strong problem-solving mindset, thriving in a fast-paced, hardware-rich, high flight cadence environment.

Responsabilidades

• Design and develop mechanical actuation systems, including elevon drive trains and control surface mechanisms.
• Lead the architecture and detailed design of mechanisms, including gear trains, linkages, bearings, and structural components.
• Perform analysis of loads, stresses, deflections, and dynamic behavior under extreme environments.
• Collaborate with control electronics, GNC, avionics, and structures teams for seamless integration.
• Conduct tolerance analysis and life/reliability assessments for high-duty-cycle systems.
• Support prototyping, assembly, and hardware bring-up, including root-cause analysis of performance issues.
• Define and execute qualification and environmental test plans (vibration, thermal, shock).
• Optimize designs for mass, stiffness, reliability, and manufacturability.
• Mentor junior engineers and contribute to best practices in mechanism design and analysis.
• Partner with program leadership to make technical trades aligned with mission success.
