Salary: $75.00 USD Hourly - $90.00 USD Hourly
Description:

We are seeking a Senior Avionics Engineer to join a rapidly growing engineering team developing flight-critical electronics for advanced air and missile platforms. In this role, you will design, integrate, and verify high-reliability avionics and embedded systems, working closely with cross-functional teams across hardware, software, firmware, mechanical, and test engineering.

This position supports new system development, active deployments, and customer-operated hardware in a fast-paced environment. The ideal candidate thrives in hands-on design work, system integration, and troubleshooting across both electrical and software boundaries.
Responsibilities

• Own full-cycle PCB design, including requirements gathering, schematic design, component selection, layout oversight or execution, bring-up, testing, debugging, and system integration
• Perform microcontroller bring-up and design, ensuring reliable integration within avionics and embedded systems
• Troubleshoot complex issues spanning electrical hardware and embedded software using lab equipment and basic software debugging tools
• Design and integrate power management systems, including power regulation, distribution, and protection
• Develop avionics payloads and subsystems, including sensors, payload interfaces, power systems, and networking
• Create system interconnect diagrams and define wire harnesses connecting electronic equipment within subsystems
• Collaborate with electrical, mechanical, software, firmware, and test engineers to deliver mission-critical products
• Participate in and lead peer-level and cross-disciplinary design reviews
• Support development, deployment, and sustainment of fielded hardware

Minimum Qualifications

• Bachelor's degree in Electrical Engineering or equivalent practical experience
• 8+ years of experience designing, testing, and troubleshooting complex electronic systems
• Experience performing power system and electrical loading analysis, simulation, and validation
• Strong hands-on experience with lab equipment (oscilloscopes, DMMs, power supplies, electronic loads, logic/spectrum analyzers)
• Familiarity with thermal and EMI testing and basic embedded software debugging tools
• Experience with common electrical and communication interfaces (CAN, I2C, SPI, Ethernet, RS-232/422, RS-485, USB)
• Hands-on experience with microcontrollers, including bring-up and early-stage design
• Strong knowledge of analog and digital electronics and mixed-signal circuit design
• Experience designing multi-layer mixed-signal PCBs, including stack-up definition, impedance control, grounding strategies, and filtering
• Understanding of low- and high-voltage power electronics and control systems, including harnessing, wire selection, and connectorization
• Excellent written and verbal communication skills
• Ability to obtain and maintain a U.S. security clearance

Preferred Qualifications

• Experience with high-end consumer, aerospace, or military embedded systems
• Experience with battery-based and AC power systems
• Ability to develop low-level firmware for system bring-up and test
• Background supporting defense, missile, or aerospace programs
• Understanding of environmental effects such as temperature and vibration on electronic designs
