Responsibilities

• Lead the design of satellite mechanical systems including primary/secondary structures, mechanisms, and electronics enclosures/modules.
• Perform detailed design using CAD tools (NX, CATIA, SolidWorks).
• Ensure compliance with launch loads, mechanical constraints, and space environment requirements.
• Optimize designs for mass, stiffness, manufacturability, and integration efficiency.
• Support satellite assembly, integration, and test (AIT) activities.
• Support mechanical integration of electronics units, harness routing, and structural interfaces.
• Define and support environmental testing (vibration, acoustic, shock).
• Support in the investigation of any anomalies during integration and testing phases.
• Select appropriate materials and surface treatments for space applications.
• Define materials and finishes suitable for electronics enclosures and mounting structures.
• Ensure compliance with space standards (e.g., outgassing, radiation tolerance, fatigue life).
• Work closely with manufacturing teams on producibility and qualification.
• Provide technical guidance to junior engineers.
• Lead design reviews (PDR, CDR, TRR, etc.).
• Collaborate with multidisciplinary teams including electrical/avionics teams to ensure proper mechanical-electrical integration.
