Safety Engineer - ARP4671 / STPA Analysis
Location: DFW
Job Type: Full-Time
Responsibilities:
● Lead and perform safety analyses in accordance with ARP4671, including Functional Hazard Assessments (FHA),
Human Factors (HF), System-Theoretic Process Analysis (STPA), Common Cause Analysis (CCA), Failure Modes &
Effects Analysis (FMEA), Fault Tree Analysis (FTA), Preliminary System Safety Assessments (PSSA), and System Safety Assessments (SSA).
● Develop and maintain the Safety Program Plan and ensure compliance with FAA/EASA certification requirements.
● Work closely with Systems Engineering to ensure that safety requirements and verification methods are defined, allocated, and traceable.
● Translate STPA-derived safety constraints and loss scenarios into system requirements, verification activities, and certification evidence that remain traceable through the safety lifecycle.
● Identify and evaluate potential hazards in aircraft systems and operations, ensuring risks are properly classified and mitigated.
● Apply STPA methods to identify unsafe control actions, causal scenarios, control-loop issues, and safety constraints across aircraft systems, operational procedures, and human-machine interfaces.
● Coordinate with flight test and design engineers to validate safety-critical requirements through analytical methods, simulation, and test evidence.
● Prepare and manage compliance evidence for certification authorities, ensuring safety documentation supports the Supplemental Type Certificate (STC) process, to include the drafting and owning of Issue Papers per AC 20-166A.
● Support design reviews, safety boards, and certification audits, presenting safety analyses and hazard mitigations.
● Collaborate with cross-functional teams to integrate DO-178C, DO-254, and DO-160 considerations into future developments.
Qualifications:
● Bachelor’s or Master’s degree in Aerospace Engineering, Systems Engineering, or a related field.
● Proven experience conducting safety assessments aligned with ARP4671 and related certification standards, with
working knowledge of STPA or system-theoretic hazard analysis methods.
● Strong background in system safety processes (FHA, PSSA, SSA, STPA, FMEA, FTA), including both traditional
reliability-based analyses and control-structure-based hazard analysis.
● Ability to develop and review STPA artifacts, including loss definitions, hazards, control structures, unsafe control
actions, causal scenarios, and derived safety constraints
● Familiarity with regulatory guidance including 14 CFR Part 23/25, ARP4754A, ARP4761.
● Ability to develop safety-related documentation, including evidence matrices for certification.
● Strong analytical, communication, and organizational skills to support high-stakes certification programs
