Leak Detector Technician Senior Level

Job Title: Leak Detector Technician Senior Level
Location: Hingham and Rockland, MA
Department: Assembly & Testing
Reports To: Lead Quality Engineer / Fabrication Supervisor
Employment Type: Full-Time

Job Summary:
Seeking a highly skilled Leak Detector Technician to ensure the integrity of welded metal chambers used in space simulation environments for satellite testing. This position plays a critical role in maintaining ultra-high vacuum (UHV) standards and ensuring all chambers meet stringent aerospace specifications.

Key Responsibilities:

• Perform leak testing on welded metal vacuum chambers using helium mass spectrometry, pressure decay, and other advanced methods.

• Inspect welds for porosity, cracks, and other defects that could compromise vacuum integrity.

• Collaborate with welders, engineers, and cleanroom technicians to ensure compliance with aerospace-grade fabrication standards.

• Interpret technical drawings, vacuum system schematics, and fabrication specifications.

• Document all test procedures, results, and corrective actions in accordance with ISO and AS9100 standards.

• Maintain and calibrate leak detection equipment for accuracy and reliability.

• Support root cause analysis and continuous improvement initiatives related to weld quality and chamber performance.

Qualifications:

• High school diploma or equivalent; technical certification in welding inspection or NDT (non-destructive testing) preferred.

• Minimum 7 years of experience in leak testing for vacuum systems, preferably in aerospace or high-tech manufacturing.

• Proficiency with helium leak detectors and vacuum system diagnostics.

• Familiarity with TIG welding and materials such as stainless steel and aluminum used in UHV environments.

• Ability to work in cleanroom conditions and follow contamination control protocols.

• Strong attention to detail and excellent documentation skills.

Preferred Skills:

• Certification in Non-Destructive Testing (e.g., ASNT Level II in Leak Testing or Visual Inspection).

• Experience with space simulation chambers, thermal vacuum testing, or satellite environmental testing.

• Knowledge of ASME, AWS D17.1, and NASA-STD welding and inspection standards.

• Understanding of vacuum physics and chamber fabrication processes.

Physical Requirements:

• Ability to lift and maneuver heavy equipment and components.

• Comfortable working in confined spaces and wearing PPE for extended periods.

• Manual dexterity and visual acuity for detailed inspections.
