Prior work experience with at least one OEM, Tier-1 avionics supplier, aircraft integrator, or certified airborne systems program.

Experience in one or more avionics subsystems such as: Flight Management System (FMS) Datalink Radio Navigation HUD Air Data IRS Displays Communication Surveillance IMA-hosted applications Must Have An experienced Avionics System Requirements Engineer who has previously performed requirements engineering activities for one or more avionics subsystems on an aircraft development or modification program.

Expected to support onsite system engineering activities including requirements development, authoring, traceability, validation, review support, and compliance alignment with customer engineering processes and applicable aviation certification standards.

Should be a practitioner-level engineer, meaning they should have already executed similar work on prior aerospace/OEM programs and should be able to contribute with limited supervision after onboarding to the customers process, tools, and templates.

Good to Have Prior experience in avionics subsystems such as: Flight Management System (FMS) Datalink / Communication Management Radio Navigation HUD / Head-Up Display Air Data System Inertial Reference System (IRS / ADIRS) Flight Control Interface Systems Displays / Crew Alerting Surveillance Systems Communication / Navigation / Identification Systems Mission or Utility Avionics Systems Responsibilities Avionics System Requirements Development and Authoring Author avionics system requirements based on stakeholder inputs, system architecture, safety requirements, operational concepts, and interface needs.

Develop requirements at appropriate abstraction levels, including: Aircraft-level allocated requirements System-level requirements Subsystem-level requirements Interface requirements Derived requirements Safety-related requirements Apply customer-specific requirements writing rules, templates, naming conventions, and Ensure requirements are transparent, concise, complete, correct, feasible, verifiable, and traceable.





Apply customer-specific requirements writing rules, templates, naming conventions, and review checklists.

Convert informal engineering into structured requirements suitable for design, implementation, integration, and verification.

Support refinement of existing requirements to remove ambiguity, duplication, inconsistency, or non-verifiable wording.

Develop requirements for avionics functions such as: Navigation data processing Flight plan management Sensor input processing Data bus communication Display output behavior Failure annunciation Mode management Built-In Test (BIT) behavior Interface monitoring Degraded mode operation Translation of Stakeholder, Safety, and System Needs into Requirements Interpret stakeholder requirements and convert them into measurable avionics system requirements.

Analyze inputs from: Aircraft-level requirements Operational scenarios Functional Hazard Assessment (FHA) Preliminary System Safety Assessment (PSSA) System Safety Assessment (SSA) Interface Control Documents (ICDs) System architecture models Certification plans Customer standards and process guidelines Translate safety objectives and failure condition classifications into system-level design and verification requirements.

Identify missing, incomplete, conflicting, or unclear stakeholder and system inputs.

Capture derived requirements generated from architecture, design constraints, interface behavior, or safety analysis.

Ensure each requirement is stated in a verifiable manner using appropriate language such as ''shall.'' Define expected system behavior for: Normal operation Abnormal operation Failure conditions Loss of input data Invalid data Degraded modes Power-up and initialization Reversionary modes Maintenance modes Certification and Process Compliance Support Support development of requirements in alignment with system development lifecycle processes such as ARP4754A.

Ensure requirements are suitable for downstream compliance with applicable standards such as:



ARP4754A for aircraft and system development ARP4761 / ARP4761A for safety assessment inputs DO-178C for software-related requirements allocation DO-254 for airborne electronic hardware-related requirements allocation DO-160 for environmental qualification considerations DO-297, where IMA platform allocation is applicable Support certification-oriented review of requirements to ensure: Traceability Verifiability Completeness Correctness Design independence where required Linkage to safety and compliance objectives Participate in certification Ensure requirements are aligned with customer/OEM methodology and certification artifact expectations.

Support preparation and review of evidence required for certification audits and internal quality gates.

Participate in certification and quality reviews related to system requirements.

Use customer-designated requirements management tools such as: IBM DOORS / DOORS Next Polarion Jama Connect Siemens Teamcenter PTC Integrity Codebeamer Enterprise Architect / Cameo, where applicable Generate traceability reports, review packages, gap reports, and change impact summaries.

Should have hands-on working experience in at least one industry-standard requirements management tool and should understand how traceability is used during reviews, audits, verification planning, and change control.

Requirements Review, Validation, and Quality Support Participate in requirements review meetings with customer/OEM teams, suppliers, and cross-functional engineering stakeholders.

Support validation of requirements against stakeholder needs and operational use cases.

Support review of requirements with: System engineering teams Safety teams Software teams Hardware teams Integration and test teams Certification representatives Supplier engineering teams Provide comments, dispositions, and technical justifications during peer reviews and formal reviews.

Support requirements baseline creation and change control activities.

Assist in defect resolution related to requirement ambiguity, interface mismatch, or verification failure.
