About The Role

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

1. 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.

1. 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.

1. 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.

1. 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.

What We Offer

• Career track opportunity with potential for rapid advancement with strong performance as the firm grows
• 100% employer paid, comprehensive health care including medical, dental, and vision for you and your family.
• Paid maternity and paternity for 14 weeks at employees' normal pay.
• Unlimited PTO, with management approval.
• Opportunities for professional development and continued learning.
• Optional 401K, FSA, and equity incentives available.

Salary Range:  $126,000-$173,000.  This represents the typical salary range for this position based on experience, skills, and other factors.
