Your Role

As a Senior Electrical Hardware Engineer (Consultant), you will take a technical leadership role in the development, verification, and documentation of Electronic Control Board Assemblies (ECBA) for our Energy Storage System (ESS). You will operate under EASA Part-21J regulations, contributing to certification deliverables with a strong focus on compliance to standards such as:

• SAE ARP4754A – System Development Lifecycle
• SAE ARP4761 – Safety Assessment for Aircraft Systems
• RTCA/DO-254 – Design Assurance for Airborne Electronic Hardware
• AMC 20-152, RTCA/DO-178, DO-331 – As applicable for systems interaction and V&V alignment
• ASTM F3230 – Electronic Parts Qualification

Key Responsibilities

Design Ownership & Technical Leadership

• Define and review Board-Level Requirements with full traceability to system functions and safety objectives
• Guide the development of mixed-signal circuits including power supplies, protections, sensing, and control interfaces
• Support or lead preliminary and critical design reviews (PDR/CDR)

Documentation & Compliance

• Produce and review technical documentation including:
  • Design Descriptions, Functional Block Diagrams, and Interface Control Documents (ICDs)
  • Design Analysis Reports (e.g., Worst Case Analysis, Error Budget, Timing, Power Dissipation)
  • Verification & Validation Plans (VTP, VTPR) aligned with ARP4754A / DO-254
• Perform peer reviews and sign-off on engineering documents as per DOA procedures
• Ensure all development data complies with DO-254, internal configuration control, and certification audit expectations
• Contribute to safety documentation such as Failure Modes and Effects Analysis (FMEA) and Hardware Development Plans

Verification, Test & Certification Support

• Define and support Verification Test Procedures (VTP), Qualification Test Procedures (QTP), and ATP (Acceptance Test Procedures)
• Ensure compliance with DO-160 environmental testing including vibration, temperature, EMI/EMC
• Participate in SOI audits and interface with certification authorities on behalf of the hardware function
• Support integration and troubleshooting of boards during system testing and environmental qualification
• Provide technical mentorship to hardware team members and promote a culture of excellence in documentation and analysis
• Review the team’s schematics, PCB layouts, and test reports
• Support the development and maintenance of checklists, guidelines, and standards used throughout the ECBA lifecycle
• Promote best practices aligned with ARP4754A and model-based/system engineering principles (DO-331)
