Matter Intelligence - Testbed Engineer

• Engineering Testbed Development & Operations • Support the setup, integration, operation, and maintenance of Matter’s engineering testbeds for sensor payloads, optics, electronics, embedded systems, flight software, and data systems. • Build and maintain lab test configurations, including optical benches, sensor fixtures, electronics racks, EGSE/GSE, power supplies, data acquisition systems, networked compute, and environmental monitoring equipment. • Configure and operate hardware-in-the-loop, software-in-the-loop, and system-level test environments. • Support testbed bring-up from early engineering prototypes through flight-like and field-ready configurations. • Maintain testbed configuration control, including hardware versions, software loads, cabling, ICDs, calibration states, and test readiness status. • Help define lab processes for safe and repeatable operation of sensitive optical, electrical, mechanical, and flight-like hardware. • Assembly, Integration & Test • Support assembly, integration, and test of optical sensor payloads, avionics, embedded compute, power systems, cabling, and mechanical interfaces. • Perform payload checkout, functional testing, interface verification, and acceptance-style testing for lab, ground, airborne, and field systems. • Support integration of imaging payloads with UAS, ground vehicles, lab fixtures, and other test platforms. • Execute test procedures for radiometric, geometric, spectral, thermal, electrical, and system-level performance verification. • Support contamination control, ESD-safe handling, connector mating, torque procedures, harness routing, and flight-hardware handling practices. • Assist with pre-test, pre-flight, and post-test inspections, configuration reviews, and readiness reviews. • Optics, Sensors & Calibration • Support calibration and characterization of Matter’s imaging systems, including spectral, radiometric, geometric, thermal, and 3D sensing performance. • Assist with optical alignment, focus checks, boresight verification, target setup, illumination control, and calibration artifact handling. • Operate calibration equipment, optical targets, integrating spheres, lamps, reference panels, environmental sensors, and supporting instrumentation. • Collect, organize, and validate calibration datasets used by engineering, science, and software teams. • Document calibration configurations, test conditions, procedures, results, and deviations in a traceable and audit-ready manner. • Electrical Integration & Troubleshooting • Support electrical integration across sensors, avionics, compute elements, power systems, GPS/INS, timing systems, telemetry, and ground support equipment. • Perform cable harnessing, connector mating, pinout verification, continuity checks, signal validation, and power distribution checkout. • Read and interpret schematics, wiring diagrams, connector pinouts, interface control documents, and electrical test procedures. • Use oscilloscopes, multimeters, logic analyzers, power supplies, electronic loads, and data acquisition equipment to debug system issues. • Troubleshoot electrical, firmware, software, timing, synchronization, and interface anomalies across integrated hardware systems. • Support root-cause analysis, corrective action, and retest activities. • Software Test, V&V & Data Systems • Support software verification and validation for embedded software, flight software, test scripts, data acquisition systems, and processing pipelines. • Execute software and system-level test procedures, including regression testing, interface testing, fault testing, performance testing, and end-to-end data flow verification. • Help define test scope, test cases, pass/fail criteria, test matrices, and verification evidence. • Support defect tracking, anomaly reporting, log review, root-cause investigation, and verification closeout. • Work with software engineers to reproduce issues, collect logs, validate fixes, and document results. • Support test automation, scripting, data organization, and repeatable test execution where appropriate. • Field, Flight & Mission Operations Support • Support flight readiness activities, including payload checkout, mission planning, pre-flight configuration, ground station setup, and post-flight data handling. • Participate in field campaigns involving ground-based platforms, airborne payloads, or remote test sites. • Support day-of-test and day-of-flight operations, including system health checks, payload monitoring, data capture, anomaly response, and post-run reporting. • Help ensure collected data is complete, properly tagged, backed up, and delivered to science, engineering, or customer teams. • Contribute to operational procedures, runbooks, checklists, lessons learned, and post-test reports. • Documentation, Configuration & Review Support • Write, maintain, and execute test procedures, integration procedures, verification plans, test reports, discrepancy reports, and operations checklists. • Support design reviews, test readiness reviews, pre-ship reviews, flight readiness reviews, and anomaly review boards. • Maintain clear records of hardware configuration, software versions, calibration status, test setup, test execution, results, and open issues. • Contribute to engineering rigor consistent with NASA/JPL, DoD, aerospace, or equivalent high-reliability development environments. • You become a bridge between engineering design, lab execution, field operations, software validation, and mission readiness. • Location & ITAR • This role is based in El Segundo, CA. Onsite work is required, with field deployments and test campaigns as needed. • Due to the nature of the work, candidates must be a U.S. citizen, lawful permanent resident, protected individual, or otherwise eligible for authorization under U.S. export control laws, including ITAR and EAR requirements.
