Gravitics is building large-scale orbital structures for commercial space operations and defense/government missions. We are seeking an Avionics Integration & Test Engineer to take full ownership of assembly, integration, and verification of avionics and power systems for large space structures and flight hardware.
You will work closely with Avionics, Software, and Manufacturing teams to ensure systems are brought up safely, correctly, and to mission requirements. This role spans both hands-on work on the build floor and technical development of electrical test procedures, system checkouts, and integrated operations. You'll be a key contributor from early integration through environmental qualification and delivery.
Key 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
Requirements:
- Deep electrical expertise with hands-on experience in electrical integration and test
- Proficiency with test equipment (multimeters, oscilloscopes, power supplies, data acquisition systems)
- Strong understanding of electrical power systems, distribution, and protection
- 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
- U.S. citizenship, lawful permanent resident status, or eligibility to obtain ITAR authorization required
