Systems Engineer

Apex Systems is seeking multiple Systems Engineers to support a Systems Engineering & Integration (SE&I) team in Everett or Renton, WA.

The ideal candidate will have strong expertise in requirements engineering, system architecture, design, verification & validation, and demonstrate knowledge of the Systems Engineering V-Diagram process as defined in ARP4754A/ARP4761 standards. This role requires collaboration across multidisciplinary teams (hardware, software, safety, and test engineering) to ensure robust system development, compliance with certification standards, and alignments to make a positive impact.

Responsibilities

• Lead and support requirements definition, decomposition, and allocation from aircraft-level to system and item level.
• Lead development and maintain functional and logical airplane and system architecture.
• Ensure functional hazard assessments (FHA), preliminary system safety assessments (PSSA), and common mode analyses (CMA) in alignment with safety objectives.
• Guide item design and implementation, ensuring traceability to all levels (e.g., DRO, SRO and SCD) requirements.
• Develop plan and execute verification and validation activities across the V-model (item verification, system integration & verification, aircraft-level verification).
• Support safety analyses (SSA, FMEA/FMES) and compliance with applicable aerospace/defense regulations (e.g., DO-178C, DO-254, ARP4754A, ARP4761).
• Lead discussions across software and hardware engineering teams during design and testing phases.
• Provide documentation and support for certification authorities (FAA/EASA).
• Participate in technical design reviews, audits, and interchange meetings.

Qualifications

• Bachelor's degree in systems engineering, Aerospace Engineering, Electrical/Computer Engineering, or related technical field.
• 9+ years of experience in systems engineering lifecycle within aerospace, automotive, or complex system domains.
• Extensive hands-on experience with V-Diagram processes (requirements, design, implementation, verification, validation).
• Knowledge of safety assessments (FHA, PSSA, SSA, CMA, FMEA/FMES).
• Familiarity with certification frameworks (ARP4754A, ARP4761, DO-178C, DO-254).
• Strong analytical thinking, clear technical writing, and ability to work in multidisciplinary teams.
• Experience with requirements management tools (e.g., DOORS) preferred
• Experience in developing system modeling (SysML/UML, Cameo, or equivalent) at the airplane and systems levels a strong plus
• Leading test planning and execution across multiple integration levels preferred
