Key Responsibilities: 

• Lead the integration, bring-up, and testing of hardware and software subsystems throughout the space vehicle production lifecycle. 

• Drive system-level validation and testing campaigns on engineering and qualification hardware, including electrical, mechanical, structural, propulsion, and avionics, to ensure sustained system functionality and reliability. 

• Plan, develop, and execute comprehensive integration and test procedures for multidisciplinary systems and subsystems, including hardware, software, and communication interfaces. 

• Develop and implement test plans and strategies for hardware development programs, coordinating across engineering functions. 

• Lead troubleshooting and failure investigations at subsystem and system level, rapidly identifying root causes and coordinating solutions across functional teams. 

• Define requirements, success criteria, and interface controls for multidisciplinary system integration activities. 

• Ensure all test activities, results, and system builds are thoroughly documented and configuration controlled to support traceability and future missions. 

• Participate in requirement reviews, design reviews, system readiness checkpoints, and integration readiness reviews. 

• Support system verification and validation activities across various test platforms. 

Required Qualifications: 

• Bachelor's degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, or related field. 

• Years of experience in system integration and/or test engineering for aerospace applications (spaceflight, satellites, spacecraft, or similar) in line with engineering level. 

• Practical experience with integration and verification of various hardware and software subsystems, such as Power, Comms (CAN, UART, RS-422, Ethernet), GNC (GPS/IMUs), RF systems, and/or Propulsion. 

• Hands-on experience with system-level test equipment (DMMs, oscilloscopes, DAQs, signal generators, flow meters, leak detection equipment, etc.). 

• Proficient in developing test plans, requirements tracing, test scripts (Python, MATLAB, or similar), and test automation tools. 

• Strong troubleshooting skills across hardware, software, and embedded systems. 

• Solid understanding of space-relevant avionics qualification and acceptance standards (e.g., NASA-STD-8739.4, ECSS, MIL-STD-1540, MIL-STD-883, NASA GEVS, or similar). 

Preferred Qualifications: 

• Experience with space vehicle or satellite bus integration & test processes. 

• Knowledge of system safety, fault management, and redundancy in space vehicle architectures. 

• Experience with environmental and EMI/EMC testing. 

• Familiarity with configuration management, requirements management, and issue tracking tools. 

• Previous work with mission operations or on-orbit test and diagnosis is a plus.
