Reliability & Maintainability 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.

Responsibilities include but not limited to:

• 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

Minimum Qualifications:

• 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

Preferred Qualifications:

• Direct experience with SysML and Model-Based Systems Engineering (MBSE) using tools like Cameo, MagicDraw, 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

Security Clearance Requirements:

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

Physical Requirements:

• 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.
