Reliability Engineer

MANTECH seeks a motivated, career and customer-oriented Reliability Engineer to join our team in Lexington Park, MD
. This is a hybrid position requiring 3 days remote and 2 days onsite.

• Participate in design reviews and document technical assumptions to maintain analytical progress despite design ambiguities
• Perform functional decomposition to map system requirements to specific hardware and software elements
• Execute Physics of Failure (PoF) analysis and component-level reliability predictions utilizing MIL-HDBK-217F (or similar part-stress methodologies) to assess hardware durability and Mean Time Between Failure (MTBF)
• Conduct comprehensive reliability analyses including FMECA per MIL-STD-1629A, Fault Tree Analysis (FTA), and Reliability Block Diagrams (RBD) to identify failure modes and develop design mitigations
• Conduct maintainability analyses such as Maintenance Task Analysis (MTA), Level of Repair Analysis (LORA), and Reliability Centered Maintenance (RCM) to develop efficient preventative schedules and most cost-effective maintenance posture
• Interface with logistics stakeholders to ensure R&M analytical outputs are formatted and optimized for seamless integration into the Logistics Product Data (LPD) environment per GEIA-STD-0007
• Develop and maintain R&M artifacts within a Model-Based Systems Engineering (MBSE) environment using SysML, ensuring all Product Support Analysis (PSA) is centralized according to the established Model Governance Plan

• Bachelor of Science in Engineering (Mechanical, Electrical, Aerospace, Systems, or a related technical discipline)
• 2+ years of experience in Reliability and Maintainability (R&M) Engineering, specifically within defense, aerospace, or complex systems integration
• Hands-on analytical and problem‑solving skills, with the ability to perform detailed functional decomposition and map system‑level requirements to hardware/software elements

• Direct experience with SysML and Model-Based Systems Engineering (MBSE) using tools like Cameo, Magic Draw, or Sparx Systems Enterprise Architect
• Deep understanding of core R&M standards, including MIL-STD-1629A (FMECA), MIL-HDBK-217F (Reliability Prediction)
• Advanced knowledge of Technical Data Package (TDP) validation, with the ability to interpret assembly drawings, parts lists, and engineering notes per ASME Y14.100 and ASME Y14.24
• Familiarity with configuration management and identification standards, specifically regarding Reference Designators per ASME Y14.44 and Configuration Management principles per ANSI/EIA-649C
• Experience identifying drawing discrepancies or design ambiguities and driving design change through formal engineering channels
• Experience in Logistics Product Data (LPD) integration, with a working knowledge of GEIA-STD-0007 and the interface between R&M artifacts and sustainment databases

• Must be a US Citizen and possess a current or active Secret Security Clearance

• Must be able to remain in a stationary position 50% of the time.
• Needs to occasionally move about inside the office or hangar environments to access aircraft, equipment, and technical files.
• Frequently communicates with co‑workers, management, and customers, which may involve delivering presentations.
• Must be able to exchange accurate information in these situations.
