• Perform precision alignment and mounting of propulsion components using specialized tools and fixtures.

• Install sensors, actuators, harnesses, and control units.

• Testing & Calibration

• Conduct functional, electrical, and mechanical tests on propulsion subsystems, including leak checks, vibration tests, and thermal cycling.

• Perform sensor calibration, actuator tuning, and electrical continuity tests.

• Record and analyze test data to ensure compliance with engineering specifications.

• Troubleshooting & Maintenance

• Diagnose and resolve assembly, wiring, and control system issues.

• Execute preventive maintenance and repairs on assembly equipment and test rigs.

• Process & Documentation

• Follow work instructions, technical drawings, and schematics with high accuracy.

• Document assembly steps, test results, and any deviations or non-conformities.

• Support continuous process improvements and participate in root-cause analysis for failures.

• Collaboration & Compliance

• Work closely with engineers, quality teams, and production supervisors to ensure smooth operations.

• Adhere to aerospace manufacturing standards, ESD controls, and cleanroom protocols when required.

• Comply with all safety regulations and environmental requirements.

Qualifications & Skills

• Associate degree or technical diploma in Mechatronics, Aerospace Technology, Electrical Engineering, or a related field (Bachelor’s degree is a plus).

• Relevant certifications (IPC, NASA-STD, or similar) preferred.

• Technical Skills:

• Proficiency in reading mechanical and electrical schematics, 3D CAD drawings, and assembly instructions.

• Experience with electrical wiring, harnessing, and PCB assembly.

• Familiarity with sensors, actuators, and control systems.

• Knowledge of vacuum systems, propulsion technology, or high-voltage components is a strong plus.

• Other Competencies:

• Strong problem-solving skills and attention to detail.

• Ability to work under minimal supervision and meet tight deadlines.

• Excellent communication and teamwork abilities.

Physical & Work Environment Requirements

• Ability to work in a cleanroom or controlled environment when required.
• Comfortable with standing, lifting components (up to 25 lbs), and working with precision tools.
• Availability for flexible shifts, including potential overtime.
