Together, We Can Make A Significant Impact

As a highly experienced Senior Satellite Mechanical Engineer, you will lead the design, development, and qualification of mechanical systems for spacecraft missions. This role focuses on structural integrity, mechanical design, electronics packaging, and system reliability in the harsh space environment.

Be Part of Our Success

Mechanical Design & Development

• Lead the design of satellite mechanical systems including primary/secondary structures, mechanisms, and electronics enclosures/modules (e.g., avionics boxes, PCB assemblies)
• Perform detailed design using CAD tools (e.g., NX, CATIA, SolidWorks)
• Ensure compliance with launch loads, mechanical constraints, and space environment requirements
• Optimize designs for mass, stiffness, manufacturability, and integration efficiency

Structural Analysis

• Conduct structural analysis (static, dynamic, vibration, shock) using FEA tools (e.g., ANSYS, NASTRAN)
• Perform structural verification of both spacecraft structures and electronics modules (PCB support, fasteners, enclosures)
• Validate designs against mission requirements and safety margins

Integration & Testing

• 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

Materials & Processes

• 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

Technical Leadership

• 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
• Drive best practices in electronics packaging, structural robustness, and interface control

Documentation & Compliance

• Generate and maintain design documentation, analysis reports, and test procedures
• Develop related interface control documents (ICDs)
• Ensure compliance with industry standards (e.g., ECSS, NASA, MIL-STD)
• Support mission reviews and customer deliverables

Qualities We Value

• Knowledge in Mechanical Engineering, Aerospace Engineering, or related field

• Preferably 8 to 15 years of relevant experience in satellite or space system engineering is a plus

• Proven experience in spacecraft mechanical design, AIT, and electronics module/box-level design is highly desirable

• Proficiency in:

  • CAD tools (NX, CATIA, SolidWorks)
  • FEA tools (ANSYS, NASTRAN)
  • Electronics packaging and PCB mechanical support design
  • Harness routing, connector interfaces, and avionics box integration

• Strong problem-solving and analytical skills

• Excellent communication and documentation abilities

• Ability to work in fast-paced, multidisciplinary environments

• Leadership and mentoring capability

• Combination of office-based design work and hands-on work in labs/cleanrooms

• Occasional travel for testing, launch campaigns, or customer engagement

• Singaporean only

Our Commitment That Goes Beyond the Norm

• An environment where you will be working on cutting-edge technologies and architectures.
• Safe space where diverse perspectives are valued, and everyone’s unique contributions are celebrated.
• Meaningful work and projects that make a difference in people’s lives.
• A fun, passionate and collaborative workplace.
