Application close date: Applications will be accepted on an ongoing basis until the requisition is closed. At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! This role is part of the Lunar Permanence business unit, which develops Blue Origin's Blue Moon landers and related products. To further Blue Origin's mission of millions of people living and working in space for the benefit of Earth, we are building sustainable infrastructure for our transport of crew and cargo from Earth to the lunar surface. You will be responsible for the comprehensive oversight and execution of contamination control for Lunar Permanence. You will share in the team's impact on all aspects of contamination control from the design phase through manufacturing and processing to meet spacecraft requirements. This position will directly impact the history of space exploration and will require your dedicated commitment and detailed attention towards safe and repeatable spaceflight. Responsibilities: Support materials selection and qualification with attention to particle generation, outgassing, and chemical compatibility for space and propulsion environments Maintain and continuously improve cleanroom, controlled work environment, and precision cleaning protocols for manufacturing, assembly, and integration operations Develop, implement, and maintain Contamination Control Plans (CCPs) for space systems, fluid systems, and precision mechanisms in accordance with applicable government and industry standards Establish cleanliness level requirements and verification approaches for turbomachinery, fluid systems, optical payloads, mechanical assemblies, and sensitive flight hardware. Plan and execute cleanliness verification testing including: Particle count analysis (liquid and airborne) Non-Volatile Residue (NVR) gravimetric and chemical analysis Witness coupon and fluid sample processing Optical and visual contamination inspections Review and approve engineering drawings, assembly procedures, and work instructions for contamination control compliance. Lead and participate in anomaly investigations and formal failure analyses involving contamination events; generate, track, and close corrective and preventive actions (CAPAs) Author and maintain engineering specifications, standards, and process documents governing contamination control. Provide M&P and contamination control inputs at formal program design reviews (SRR, PDR, CDR, TRR, FRR) and Technical Interchange Meetings (TIMs) Interface with government customers, program offices, and prime contractors on contamination control requirements, compliance status, and data deliverables Support supplier audits and surveys to ensure vendor compliance with contamination control requirements Assess material and fluid compatibility for propulsion systems utilizing liquid oxygen (LOX), liquid hydrogen (LH2), RP-1, hydrazine, and high-pressure pressurants Mentor and provide technical guidance to production technicians and manufacturing engineers Basic Qualifications: Bachelor's degree in Materials Science, Mechanical Engineering, Chemical Engineering, Aerospace Engineering, or closely related technical discipline 5+ years of experience in Materials & Processes engineering with demonstrated focus on contamination control in aerospace, defense, or precision spaceflight hardware environments U.S. Citizenship required (position subject to ITAR and U.S. Government contract requirements) Working knowledge of contamination control standards and specifications, including: IEST-STD-CC1246 - Product Cleanliness Levels and Contamination Control Program MIL-STD-1246 - Product Cleanliness Levels and Contamination Control ASTM E595 - Total Mass Loss and Collected Volatile Condensable Materials (outgassing) ISO 14644 - Cleanroom classifications and controlled environments NASA-STD-5300 series or equivalent DoD/government cleanliness standards Hands-on experience with cleanliness verification techniques: particle counting, NVR analysis, gravimetric testing, witness coupons, and optical inspection Demonstrated experience writing technical specifications, engineering instructions, and compliance documentation to government program standards Familiarity with precision cleaning methods for metallic and non-metallic aerospace hardware Strong root cause analysis and structured problem-solving skills Preferred Qualifications: Master's degree in a relevant engineering discipline Experience with liquid propellant rocket engine cleanliness and propulsion fluid system contamination control (LOX, LH2, RP-1, hydrazine, pressurants) Familiarity with M&P as a generalist in one of the following areas: EEE, cable and harness, metallics and coatings Backgrou #J-18808-Ljbffr Blue Origin
