System Test Automation Engineer Jobs in California

Design and develop software architectures for automated optical, electrical, MEMS, and system-level test stations.

Translate engineering test requirements into modular, maintainable, and reusable automation frameworks.

Integrate laboratory instruments, motion systems, control electronics, DUT interfaces, and supporting hardware into unified test environments.

Build systems that can evolve from early engineering benches into repeatable validation, qualification, and manufacturing test stations.

Define station configuration, initialization, calibration, sequencing, error handling, and recovery strategies.

Develop and maintain instrument drivers and abstraction layers for equipment such as tunable lasers, optical power meters, optical spectrum analyzers, detectors, polarization controllers, motion stages, environmental equipment, FPGA/ASIC boards, and MEMS control electronics.

Interface with hardware using protocols such as VISA, SCPI, TCP/IP, USB, serial, GPIB, REST APIs, or vendor SDKs.

Create reusable APIs that allow engineers to interact with complex instrumentation consistently and efficiently.

Debug communication, synchronization, timing, and hardware/software integration issues across test stations.

Develop scalable automated test frameworks using Python, C++, LabVIEW/TestStand, or similar technologies.

Implement test sequencing, parameterization, configuration management, automated calibration, limits checking, and result handling.

Enable engineers to rapidly create and modify test cases without rebuilding station infrastructure.

Automate repetitive and time-consuming validation workflows to improve throughput, repeatability, and test coverage.

Develop tools and interfaces that make complex test stations accessible to optical, hardware, reliability, and validation engineers.

Build reliable data acquisition pipelines from instrument and DUT readout through structured storage, logging, and downstream analysis.

Define schemas and metadata structures that preserve device, station, configuration, environmental, and test context.

Ensure datasets are traceable and reproducible across devices, stations, software revisions, and experiments.

Support visualization and engineering analysis workflows by providing clean, structured test outputs.

Implement robust logging, diagnostics, exception handling, and station health monitoring.

Turn prototype engineering setups into reproducible, documented station platforms that can be deployed across multiple labs.

Develop station software with scalability, maintainability, version control, and reproducibility in mind.

Establish Git-based development workflows, code review, automated testing, release management, and documentation practices.

Support deployment, commissioning, debugging, and maintenance of test stations.

Partner with manufacturing and operations teams as test platforms move toward pilot and production environments.

• Work closely with optical characterization engineers to automate established measurement methodologies.

• Collaborate with photonics, MEMS, hardware, firmware, systems, reliability, and product validation engineers to understand test requirements.

• Translate experimental procedures into reliable automated workflows while preserving measurement integrity.

• Instrument test stations to support deeper debug modes, failure analysis, and engineering investigations.

• Provide feedback on testability and automation requirements as new hardware and products are developed.
