Job description

Acron Aviation designs, engineers, and manufactures certified avionics systems that support safety-critical flight operations across commercial and military aviation. Within Avionics, the Surveillance product line develops and sustains systems that enable aircraft awareness, collision avoidance, and airspace interoperability. Our portfolio includes TCAS, Mode S transponders, ADS-B, and integrated surveillance solutions deployed across commercial, military, and rotorcraft platforms. This work is performed in highly regulated environments and demands deep expertise across systems, hardware, software, and RF throughout the full product lifecycle.

**This requisition is being utilized to build a pipeline of qualified candidates for potential future opportunities as they arise**

Position Summary

We are seeking an early- to mid-career Firmware Engineer to join our surveillance hardware product development team. In this role, you will be responsible for designing, developing, verifying, and maintaining safety-critical firmware for avionics and embedded systems for TCAS and transponder applications in compliance with DO-254 standards. You will work closely with hardware engineers, system architects, and certification authorities to ensure robust design assurance processes are followed throughout the product lifecycle. Ideal candidates will have a deep understanding of FPGA/ASIC development, VHDL/Verilog, and requirements-based verification, with experience developing firmware for FAA/EASA-certified aerospace systems.

You will be involved with multidisciplinary project teams involving mechanical, electrical digital/analog, RF, firmware, and software engineering in planning, designing, prototyping, and testing of avionics systems. Design focus will include surveillance avionics for Air Transport, as well as General Aviation and emerging platforms such as Urban Air Mobility (UAM) eVTOL aircraft.

Key Responsibilities

• Design, develop, implement, and maintain FPGA-based hardware solutions using industry-standard development tools and methodologies.
• Develop and verify FPGA designs utilizing VHDL and/or Verilog RTL coding techniques.
• Perform simulation, debugging, and validation activities to ensure designs meet functional, performance, and quality requirements.
• Execute requirements-based verification activities and document verification results in accordance with program and certification requirements.
• Apply DO-254 processes, standards, and best practices throughout the airborne electronic hardware development lifecycle.
• Create, maintain, and update hardware design documentation, including Hardware Requirements Documents (HRDs), Hardware Design Documents (HDDs), Hardware Configuration Indexes (HCIAs), and other technical artifacts.
• Prepare and maintain certification documentation, including Plan for Hardware Aspects of Certification (PHAC) and related compliance deliverables.
• Collaborate effectively with cross-functional engineering, quality, certification, and program teams to achieve project objectives.
• Engage directly with internal and external customers to understand technical requirements, identify challenges, and develop actionable solutions.
• Present technical information clearly and effectively in written, verbal, and virtual communication settings.
• Support program execution by participating in design reviews, technical assessments, and problem-resolution activities.
• Perform other job-related duties as assigned.
• Travel up to 10% as required to support customers, project activities, and business needs.
