Full Time Technical Gilbert, AZ, US

Senior Test & Integration Engineer

Position 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 Like

Components 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.
