Test Development Engineer

The Test Development Engineer is responsible for defining, developing, and supporting automated test systems that enable efficient and scalable production of embedded computing hardware. The role is engaged early in the product and board design cycle to drive testability, define ATE requirements, and shape the overall test architecture., * Engage early in PCB/board design reviews to define Design for Testability (DfT) requirements and influence product architecture.

• Capture, document, and maintain ATE requirements aligned with product and production needs.
• Work collaboratively with software ATE engineers to define and develop the overall ATE architecture (hardware, software, instrumentation, fixtures).
• Specify and design hardware elements of ATE systems, including fixtures, ITAs, harnesses, interface boards, and switching.
• Support development of automated test sequences and diagnostic routines with software ATE teams.
• Provide technical leadership through NPI, pilot builds, and full-scale production.
• Troubleshoot test failures, perform root-cause investigations, and drive yield and throughput improvements.
• Validate and qualify ATE systems before release to manufacturing.
• Maintain clear documentation: test procedures, interface schematics, wiring diagrams, and maintenance guides.
• Provide ongoing support for deployed ATE, including upgrades, calibration strategies, and process improvements.
• Support production growth by scaling test solutions, improving capacity, and optimizing test performance.
• Collaborate with design authority to provide input on product design and ensure alignment on test strategy.

• Strong understanding of electronic hardware: digital/analog circuits, power sequencing, timing, and high-speed interfaces.
• Proven experience developing or supporting Automated Test Equipment in a production environment.
• Ability to define and influence test requirements early in product design.
• Experience collaborating with software ATE developers to build integrated test platforms.
• Proficiency with test instrumentation (oscilloscopes, PSUs, switching hardware).
• Familiarity with test automation tools.
• Experience with DfT, BIST, and diagnostic firmware features.
• Strong troubleshooting and fault-isolation capability.
• Strong documentation and requirements-writing skills.
• Ability to work effectively with hardware, firmware, software, production, and quality teams.

Desirable Skills:

• Experience with embedded computing systems or complex multilayer PCBs.
• Knowledge of manufacturing processes (SMT, assembly, AOI, functional test).
• Understanding of reliability analysis, yield improvement.
• Experience with qualification or environmental testing.
• Ability to design simple custom electronics for test fixtures or adapters.
• Experience in aerospace, defense, industrial computing, or other high-reliability environments
• Experience planning test capacity and designing ATE systems for production scaling and throughput growth
