Summary of the NDT Engineer, Computed Tomography (CT Level III) job at Impulse Space

Responsibilities

• Develop, validate, and maintain CT inspection techniques for aerospace hardware. This includes scan parameters, reconstruction settings, and analysis workflows matched to each part's geometry, material, and inspection goals
• Demonstrate and document inspection capability, including image quality, resolution, detectability limits, and repeatability, using reference standards, image quality indicators, and representative defect specimens
• Write and maintain CT procedures, technique sheets, work instructions, and process specifications
• Lead CT inspection planning for critical hardware, including welds, additively manufactured parts, composites, pressure vessels and COPVs, and complex assemblies
• Review and interpret CT data, disposition findings against acceptance criteria, and clearly explain results and their impact on the hardware to Engineering, Manufacturing, and Quality
• Work with Design and Structures teams to set CT acceptance criteria and inspection requirements for fracture-critical and safety-critical hardware
• Support failure investigations, root-cause analysis, nonconformance and MRB dispositions, and process development involving internal features or volumetric defects
• Decide when CT is the right tool compared with other NDT methods or outside inspection services, based on technical fit, cost, and schedule
• Lead selection, installation, commissioning, calibration, maintenance, and upgrades of CT systems and analysis software
• Work with Environmental Health and Safety to make sure CT operations meet radiation safety and regulatory requirements
• Set standards for how CT data is stored, retained, and traced for flight hardware records
• Work with Design and Manufacturing Engineering to improve how easily parts can be inspected, how reliably defects are detected, and how repeatable inspections are
• Qualify, audit, and manage outside CT and specialty inspection suppliers when internal capability is unavailable or not sufficient
• Train, examine, and mentor NDT personnel in CT practices, data interpretation, and procedures, in line with the company's NDT written practice

Minimum Qualifications

• Bachelor's degree in Engineering, Materials Science, Physics, or a related technical field
• 5+ years of industrial NDT experience, including hands-on work developing, implementing, or maintaining industrial CT inspection methods
• Current ASNT NDT Level III certification in Radiographic Testing (RT)
• Demonstrated experience interpreting volumetric inspection data and evaluating internal features, discontinuities, and defects in aerospace or similar high-reliability hardware
• Working knowledge of how NDT programs run, including personnel qualification (NAS 410 / EN 4179), procedure development, and equipment qualification
• Ability to communicate technical findings clearly and defend inspection decisions to engineering and program leadership

Preferred Skills and Experience

• Advanced degree in a related technical field
• Demonstrated experience maintaining a CT inspection capability that supports an aerospace flight program
• Demonstrated experience with CT inspection of AWS D17.1 Class A welds, COPVs, and pressure vessels built to AIAA S-080/S-081 or similar standards, additively manufactured parts, castings, or composites
• Familiarity with space-industry NDE requirements, such as NASA-STD-5009 for fracture-critical hardware, and ASTM E1441, E1570, and E1695
• Demonstrated experience with high-energy CT, metrology CT (dimensional measurement), image-quality optimization, and artifact reduction
• Demonstrated experience designing probability of detection (POD) studies or other reliability demonstrations for NDE methods
• ASNT Level III certifications in other methods, such as UT, PT, or ET
• Demonstrated experience writing acceptance criteria and working with design teams on design-for-inspection requirements
• Scripting or automation experience (for example, Python) for CT analysis workflows
