Avionics Electrical Engineer

About the role

This is a hands-on, cross-functional role supporting GNC, power distribution, instrumentation, communications, RF systems, flight software, test, manufacturing, and vehicle integration. You will own detailed hardware design while also understanding how that hardware performs at the subsystem and integrated vehicle level.

Responsibilities

• Design, analyze, integrate, and test avionics and electrical systems for flight vehicles, ground test assets, and supporting infrastructure
• Own electrical hardware from concept through design, procurement, build, checkout, qualification, and vehicle integration
• Create or interpret schematics, wiring diagrams, interface control documents, or test procedures
• Support architecture trades across power distribution, instrumentation, controls, data acquisition, communication buses, and RF interfaces
• Work with GNC, flight software, propulsion, structures, hydraulics, test, manufacturing, and operations teams to define requirements and integrated solutions
• Perform electrical design analysis, including power budgets, signal integrity, thermal considerations, grounding/bonding, and interface compatibility
• Bring up, troubleshoot, and modify electrical systems at the bench, subsystem, and vehicle level
• Support ground test, environmental test, integrated vehicle test, and flight test campaigns
• Maintain configuration control over avionics hardware, drawings, wiring diagrams, work instructions, test procedures, and as-built documentation
• Support design reviews, test readiness reviews, failure investigations, and risk mitigation planning
• Work hands-on with technicians, test engineers, and manufacturing teams to quickly resolve issues and keep hardware moving

Requirements

• Bachelor’s degree in electrical engineering or a related engineering discipline
• 4+ years of experience in electrical hardware design, avionics integration, instrumentation, control systems, digital communication buses, analog design, power electronics, harness design, or vehicle electrical systems
• Strong troubleshooting skills and comfort working hands-on with electrical hardware
• Bias toward action and willingness to operate in a fast-paced hardware development environment

Preferred Skills And Experience

• Master’s degree in electrical engineering, mechanical engineering, aerospace engineering, or a related discipline
• Experience with embedded systems, device integration, verification and validation, environmental qualification, ground testing, or flight testing
• Experience with avionics devices, sensors, data acquisition, telemetry, instrumentation, or signal conditioning hardware
• Familiarity with tools such as DMMs, oscilloscopes, power supplies, SPICE, MATLAB, LabVIEW, or Ansys
• Familiarity with tools such as Altium Designer, Siemens NX, Teamcenter, Git, Jira, Jama, Confluence, or similar tools
• Familiarity with avionics interfaces and hardware such as RS-485, Ethernet, ARINC-429, CAN, GPS, INS, FPGAs, D38999-style connectors, or similar
• Familiarity with aerospace standards such as IPC-620, MIL-STD-810, MIL-STD-704, MIL-STD-461, MIL-STD-464, MIL-HDBK-516, or DO-160
• Experience with DC power systems, batteries, motors, generators, power distribution, grounding, bonding, or EMI/EMC
• Experience supporting vehicle bring-up, integrated checkout, anomaly resolution, or test operations
• Project experience with aircraft, launch vehicles, spacecraft, UAVs, missiles, defense systems, or other complex hardware platforms

Benefits

• Health & Wellness: 100% employer-paid healthcare and pet insurance
• Financial: Competitive pay, stock options, 401(k) retirement plan, and potential year-end bonuses
• Time Off: Paid parental leave, 12 federal holidays, unlimited PTO for exempt employees, and generous accrued PTO for non-exempt employees
• Office Perks: Weekly paid office lunches and fully stocked breakrooms
