Job Description
Technical Skills
Bachelors or Masters degree in any one of the following:
Aerospace Engineering
Avionics Engineering
Electronics Engineering
Electrical Engineering
Computer Science
Systems Engineering
Instrumentation Engineering
815 years of avionics systems engineering experience.
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 clear 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.
