Test Systems Engineer

Claros Technologies is seeking a highly skilled, self-motivated Test System Engineer to help drive the development of next-generation power delivery and semiconductor technologies. In this role, you’ll design and implement automated test systems, custom PCBs, and evaluation hardware to validate cutting-edge integrated voltage regulators and high-power demonstrators. You’ll work hands-on in the lab and collaborate across design, packaging, and system teams to ensure accurate, data-driven performance validation from silicon to full system integration. This is an exciting opportunity for an engineer who thrives on innovation, precision, and solving complex system challenges in a fast-moving R&D environment. What You Will Do Test System Architecture & Development Define and develop test system architecturefor validating power conversion ICs, modules, and subsystems. Integrate hardware and software components—bench instruments, DAQs, power analyzers, load systems, and thermal sensors—into unified automated setups. Design custom interface boards, test fixtures, and harnesses to support automated validation and reliability testing. Establish robust test methodologies for efficiency, thermal, and transient performance characterization. Develop scalable test infrastructurefor prototype and production-intent platforms. Hardware Design & PCB Development Design evaluation and control PCBsfor IVR, converter, and power module testing. Implement features for telemetry, fault monitoring, and safety interlocks. Ensure PCB designs comply with DFT (Design for Test) and DFM (Design for Manufacturing) guidelines. Work with external vendors for fabrication and assembly, and lead bring-up/debug of evaluation hardware. Test Automation & Data Systems Develop and maintain automated test scripts using Python, LabVIEW, or MATLABto control instruments and log data. Create test frameworks to manage multiple devices and complex test sequences. Automate post-processing, data visualization, and report generation. Support calibration, traceability, and repeatability across test systems. System Integration & Validation Collaborate with silicon, packaging, and system teams to define interface, telemetry, and control requirements. Validate system performance—including electrical, thermal, and control loop stability—against specifications. Contribute to reliability and environmental test plans (thermal cycling, load transients, and power-on stress). Participate in bring-up of full demonstrator systems(e.g., embedded glass substrate modules, TTV platforms). What You Bring Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related discipline. 4–8 years of experience developing automated test systems for semiconductors, power electronics, or mixed-signal ICs. Hands-on experience with bench instrumentation, automated test software, and PCB design. Proficiency in test scripting(Python, LabVIEW, C/C++, or MATLAB). Knowledge of power conversion, analog/digital circuits, and embedded control. Familiarity with data acquisition, communication protocols (I²C, SPI, PMBus, CAN, etc.), and control loop analysis. Experience with hardware bring-up, debugging, and root cause analysis.
