Avionics Integration & Test Engineer

Gravitics•Seattle, WA

About The Position

Gravitics is seeking exceptional engineers with deep electrical expertise to take full ownership of the assembly, integration, and verification of avionics and power systems for large space structures and flight hardware. This role involves close collaboration with Avionics, Software, and Manufacturing teams to ensure systems are brought up safely, correctly, and to mission requirements. The position spans both hands-on work on the build floor and technical development of electrical test procedures, system checkouts, and integrated operations. The engineer will be a key contributor from early integration through environmental qualification and delivery.

Requirements

3–5+ years of experience in integration, test, or systems-focused engineering with a strong electrical focus
Bachelor's degree in Electrical Engineering or closely related ABET-accredited engineering discipline
Deep understanding of circuit components, digital/analog electronics, power supplies, and avionics architectures
Experience writing and executing electrical test procedures for subsystem and system-level hardware
Proficiency with electrical test equipment including DMMs, oscilloscopes, spectrum analyzers, and logic analyzers
Experience with scripting or automation tools for test execution and data collection
Ability to interpret electrical schematics, wiring diagrams, and interface control documents
Strong problem-solving skills using first-principles and systematic troubleshooting
Comfortable working in fast-paced environments with shifting priorities
Ability to lift up to 25 lbs and work around large hardware
Must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Nice To Haves

Experience with spacecraft, launch vehicles, or other high-reliability aerospace systems
Familiarity with environmental testing including thermal, vibration, shock, and EMI/EMC
Experience with EGSE design, cable harness integration, or specialized test rack build-up
Knowledge of avionics architectures, bus protocols (Ethernet, RS422, CAN, etc.), and flight software interfaces
Experience in SIL and HITL test setups
Experience developing work instructions or supporting technicians during integration
Background in safety-critical or configuration-controlled environments

Responsibilities

Own the design, build, integration, and troubleshooting of Hardware-in-the-Loop (HITL) and Electrical Ground Support Equipment (EGSE) test systems
Develop, refine, and execute detailed electrical test procedures for functional and environmental testing of avionics, power systems, and electronic assemblies
Perform subsystem-level testing and end-to-end electrical integration, including monitoring and evaluating telemetry data
Conduct functional checkouts, including electrical continuity testing, power-on sequencing, and integrated system operations
Troubleshoot and resolve off-nominal electrical behavior in flight hardware and EGSE
Interpret electrical schematics, block diagrams, wiring diagrams, and interface control documents (ICDs)
Contribute to Test Readiness Reviews (TRRs) and validate test results against design requirements
Ensure hardware integration complies with safety standards, configuration control, and quality requirements
Support test data review, anomaly documentation, and issue tracking
Collaborate with manufacturing, design, quality, and operations teams during build-to-test handoffs
Drive continuous improvement of integration processes, test methods, and documentation
