Avionics Hardware Development Engineer

The role

This role ensures avionics systems are buildable, testable, and repeatable at scale. You will act as the continuity layer between design, production, test, and supply chain to drive issue resolution and improve yield.

What you will do

• Own first line response to build, test, and integration issues across avionics hardware
• Perform root cause analysis and drive corrective actions across design, process, and supply chain
• Partner with manufacturing to resolve build issues quickly and improve throughput
• Ensure released designs are manufacturable, testable, and scalable to production
• Drive ECOs and systemic improvements based on real production and test feedback
• Support system-level integration across power, comms, and timing between subsystems
• Work with supply chain to ensure BOMs are executable and risks are identified and mitigated early
• Identify and eliminate recurring issues to improve first-pass yield and reduce rework
• Help define and improve production, test, and integration workflows for avionics systems
• Act as the bridge between design, production, and test to ensure continuous improvement

Required qualifications

• Bachelor’s degree in electrical, mechanical, aerospace, or related engineering field
• 3+ years of experience in hardware development, manufacturing, test, or integration engineering
• Experience working with avionics or electronic hardware (PCBs, harnessing, power systems, etc.)
• Strong troubleshooting and root cause analysis skills across electrical and mechanical systems
• Experience supporting production or integration of complex hardware systems
• Ability to work cross-functionally across design, manufacturing, test, and supply chain
• Strong ownership mindset in fast-paced, high-ambiguity environments

Nice to have

• Experience supporting hardware from design through production and integration
• Experience with system-level debugging (power, comms, timing issues)
• Familiarity with ECO processes, configuration management, and quality systems
• Experience working with contract manufacturers (CMs)
• Experience with scripting or data analysis (Python, SQL, or similar)
• Background in high-reliability or high-rate hardware environments (aerospace, automotive, etc.)

Benefits

• Equity in Apex
• 100% company-paid medical, dental, and vision for you and your dependents
