Senior Test & Integration EngineerPosition Summary Advanced Technology Systems Company (ATSC) in Gilbert, AZ is seeking a Senior Test & Integration Engineer to architect and lead our new fixture-based test program for electronic components and sub-assemblies - cameras, LiDARs, radars, controllers, and related sensor hardware. This engineer will study how these systems actually communicate and behave once installed - power sequencing, communication buses, command/response behavior, firmware and configuration state - and translate that understanding into purpose-built test fixtures, combining custom and off-the-shelf hardware, cabling, and software, that can validate a component as if it were already part of a live system. This is a hands-on technical leadership role: you will set the technical direction, build the first fixtures yourself, and lead two Manufacturing Engineers in scaling the program.
Key Responsibilities- System & Protocol Reverse Engineering - Analyze existing electronic assemblies (radars, LiDARs, cameras, controllers) to understand their power requirements, communication protocols, command/response structure, and firmware behavior when no complete documentation exists.
- Test Fixture Architecture - Design end-to-end bench test fixtures - hardware, cabling/harnessing, and control software - that emulate the system-level environment a component would see once fully integrated, so it can be validated stand-alone with confidence.
- Build vs. Buy Decisions - Determine which fixture elements to design and build in-house versus source commercially, balancing cost, schedule, and fidelity to the real operating environment.
- Software & Automation Development - Develop or direct the development of the software layer that drives each fixture - automated test sequencing, data capture, and pass/fail (and on) determination.
- Technical Leadership - Lead and mentor two Manufacturing Engineers, translating direction from the Director of Operations into a prioritized fixture build plan, and reviewing their fixture and procedure designs for technical soundness.
- Process Ownership - Own the transition of component verification from ad-hoc, downstream testing (IRT/ATP/FAI) to structured, front-loaded bench verification, driving a substantial reduction in total test hours and touch time.
- Data & Traceability - Ensure every test produces a clear pass/fail result plus supporting data (logs, measurements, configuration records) that is traceable to a specific serialized unit.
- Program Scalability - Build the fixture library and documentation so that new component types and future programs can be onboarded quickly using reusable infrastructure.
Required Qualifications- Bachelor's degree in Electrical Engineering, Computer Engineering, or related field, or equivalent hands-on experience.
- Demonstrated experience reverse-engineering electronic hardware and embedded/firmware behavior on complex systems (sensors, avionics, radar/LiDAR/camera systems, or similar) without complete OEM documentation.
- Strong background in electronics test - communication buses (e.g., CAN, Ethernet, SPI/I2C, RS-422/485, or similar), power systems, and signal/continuity verification.
- Proven experience designing test fixtures or bench setups from the ground up, including cable/harness design and hardware selection.
- Software development experience for test automation and instrument/DUT control (e.g., Python, LabVIEW, or comparable).
- Experience leading or mentoring other engineers on a technical program.
Preferred Qualifications- Experience testing or integrating sensor payloads (radar, LiDAR, camera/vision systems) in a defense, aerospace, or autonomy environment.
- Familiarity with IRT, ATP, and FAI test and acceptance processes in a manufacturing environment.
- Experience with andon-style pass/fail reporting systems or automated test data logging.
- Prior experience standing up a test and integration function from scratch.
What Success Looks LikeComponents arrive on the build floor as known-good, configured, serialized units. Downstream integration testing shrinks dramatically because verification already happened on the bench, and the two-person Manufacturing Engineering team is executing a shared fixture roadmap under this engineer's technical direction.
