In this role, you will own the obsolescence and diminishing manufacturing sources problem for AIRMOB's KC-135 R and C-135 FR fleet, aircraft that have decades of service still ahead of them despite being out of original production. You will identify component and repair-source risks before they ground a tail, build the mitigation pathway, whether that is alternate sourcing, PMA evaluation, owner-produced parts, repair development, or engineered substitution, and coordinate the cross-functional execution that keeps our aerial refuelling capability sustainable. You will be successful if our maintainers and crews never lose a mission to a part they should have known was going away. What You'll Do Lead AIRMOB's DMSMS program by identifying obsolescence and material availability risks across the KC-135 R and C-135 FR fleets and tracking them in AMOS before they impact the line. Develop and execute mitigation strategies including alternate part sourcing, PMA evaluation, owner-produced parts under 14 CFR 21.9, surplus and used serviceable material qualification, repair source development, and engineered substitutions. Partner with Quality & Airworthiness (CASS and Reliability) and Maintenance Programs to translate reliability and removal data into early warning signals for at-risk components. Serve as the primary interface among Global Supply Chain, Engineering, Maintenance Operations, the Technical Library, and AIRMOB leadership on obsolescence resolution. Build and maintain the obsolescence tracking dashboard in AMOS, documenting status, mitigation owner, and resolution path for every flagged item. Develop cost-benefit analyses for redesign versus repair versus alternate-source decisions and report obsolescence cost exposure to capability area leadership. Engage OEMs, MR - Os, distributors, and DLA on supply availability, last-time-buy opportunities, and capability list amendments. Ensure all obsolescence corrective actions are documented and substantiated to satisfy applicable airworthiness requirements, including 14 CFR Parts 21, 43, and 91 as applicable, and the AMMT. What You'll bring Must Haves. Seven or more years of aerospace sustainment, supply chain, or engineering experience, including direct work on aircraft component obsolescence or DMSMS. Hands-on familiarity with FAA approval pathways for non-OEM parts: PMA, owner-produced parts under 14 CFR 21.9, and FAA Form 8130-3 documentation flow. Demonstrated ability to read and interpret engineering drawings, illustrated parts catalogs and breakdowns, and military and aerospace technical data and specifications. Experience working in a maintenance information system such as AMOS, GOL - Desp, TRAX, or equivalent, with the ability to build and maintain structured tracking and reporting. Strong written and verbal communication skills, including the ability to brief senior leadership on risk and to negotiate technical and commercial terms with OEMs and suppliers. Bachelor's degree in Engineering (Mechanical, Electrical, Aerospace, or Industrial) or an equivalent combination of military technical training and professional experience. Nice to Haves. Prior work on legacy DoD platforms, particularly the KC-135 family, C-130, or other large transport or tanker aircraft. DAU DMSMS coursework (DAU CLL 201 or equivalent) or working knowledge of SAE GEIA-STD-0016. Experience with experimental exhibition certificate operations or NAVAIR and DCMA contract environments. Familiarity with electronic component obsolescence (avionics, communications, navigation systems) and counterfeit-parts mitigation per AS 6081. SQL or basic data analysis skills for parts and reliability data exploitation. Additional Eligibility Qualifications Must be a U.S. person as defined under 22 CFR 120.62 (U.S. citizen, U.S. lawful permanent resident, or protected individual under 8 U.S. C. 1324 b(a)(3)) due to access to ITAR and EAR controlled technical data. Must be eligible to obtain and maintain a U.S. Government Secret security clearance. Position requires adherence to U.S. export control regulations (ITAR/ EAR). Employment is contingent on successful completion of a background investigation. Our Firmware At Metrea, our single core value, Rooted in Humility, and our four cornerstone attributes - Entrepreneurial, Systematic, Discerning, and Over-Deliver. These form what we call our Teammate Firmware. Just like technical firmware connects software and hardware, our Firmware is the constant interface between our mission and our people. It defines how we show up, how we work together, and how we solve complex problems. Our team Firmware creates a web-like, hyper-collaborative, dynamically hierarchical way of working that helps us adapt quickly, communicate openly, and distribute decision-making to where expertise actually lives. It enables groups to self-organize around hard problems, shift fluidly as priorities evolve, and operate with the trust, curiosity, and discipline required in a complex mission space. This foundation allows us to deliver elegant, effective solutions and uphold our purpose: protecting our precious inheritance.
