System Safety Engineer

Primary Responsibilities

Leidos Defense is seeking a System Safety Engineer to join a matrixed organization of systems engineers, model‑based systems engineers, and specialty systems engineers. This role will support between one and three efforts simultaneously, which the engineer will autonomously balance during a 40‑hour workweek. Efforts span a range of applications—from physics‑based modeling & simulation to hardware development—and include both classified and unclassified work.

The Engineer will work independently, defining tasking derived from customer needs and contractual documents. Each effort requires specific safety artifacts; broadly, the engineer will perform system safety analysis tasks in accordance with MIL‑STD‑882E and customer program requirements. In a matrixed environment that supports multiple programs across diverse engineering fields, the engineer will have the opportunity to transition to a new program after each effort.

Experience in Systems Engineering, Human Factors Engineering, Risk Management, or Reliability Analysis is preferred. Success in this organization can lead to leadership positions in System Safety Engineering, Systems Engineering, and Systems Engineering Integration & Test (SEIT).

• A Bachelor’s degree in Systems Engineering, Software Engineering, Computer Science, Computer Engineering, Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or an equivalent degree from an ABET‑accredited university with eight or more years of experience, or an MS with six or more years.
• Demonstrated familiarity with MIL‑STD‑882E and its application to system safety programs.
• Experience deriving requirements for complex electrical, electro‑mechanical, mechanical, and software systems.
• Capability to perform in a collaborative engineering environment with multi‑disciplinary teams.
• Effective communication skills within a team environment.
• Resident of the North Alabama area or willing to relocate to the Huntsville – North Alabama, AL area.
• Possession of a secret clearance.

• Master of Science in Safety or System Engineering from an ABET‑accredited university, and/or at least four years of direct system safety engineering experience.
• Familiarity with AR 385‑10, AR 385‑16, AR 770‑3, and AMCOM 385‑17.
• Knowledge of Army Safety Board processes and preparation.
• Experience conducting hazard analyses (PHA, FHA, SHA, SSHA, O SHA, EHA, HHA, FTA, FMEA).
• Proficiency with safety tools and databases (e.g., hazard tracking systems, model‑based systems engineering, requirement databases).
• Experience leading a team of engineers.
• Ability to estimate the engineering effort (in hours) associated with System Safety Engineering tasks accurately.
• Understanding of the DoD acquisition processes and methods.
• Experience supporting one or more DoD programs.
• Object Management Group (OMG) Certified System Modeler Professional (OCSMP) certification.
• INCOSE Systems Engineering Professional (SEP) certification (ASEP or CSEP).
