Sr. Engineer, Test Engineering

About SiTime SiTime is the Precision Timing company. Timing is the heartbeat of all electronics, ensuring performance, resilience and scalability. For decades, quartz devices, non-silicon technology, have kept systems in sync, but they struggle in harsher, more demanding environments. MEMS-based Precision Timing delivers greater accuracy, smaller size and resilience. Today, MEMS timing powers over 400 applications, including high-growth ones in AI datacenters, automated driving, industrial and humanoid robots, wearables and IoT. Our semiconductor MEMS programmable solutions offer a rich feature set that enables customers to differentiate their products with higher performance, smaller size, lower power, and better reliability. With more than 4 billion devices shipped, SiTime is changing the timing industry. For more information, visit: www.sitime.com. Job Summary As a Test Development Engineer, you will contribute to the development, validation, and deployment of production test solutions for Automated Test Equipment (ATE) and oven-based trimming/calibration systems. Working closely with product, design, manufacturing, and quality teams, you will support new product introduction (NPI), test program development, hardware bring-up, and data analytics initiatives to ensure robust and scalable manufacturing test solutions. This position offers an excellent opportunity for early-career engineers to gain hands-on experience in semiconductor test development, automation, system integration, and data-driven yield improvement. Candidates with strong technical fundamentals, programming aptitude, and a passion for problem-solving are encouraged to apply. It is not necessary to meet all job requirements to be a qualified candidate for the position. Responsibilities: Test Solution Development • Develop, validate, and release production test programs for Eagle Test Systems (ETS88) and oven-based trimming/calibration systems. • Support new product introduction (NPI) activities by developing test methodologies and characterization plans. • Lead test program debugging, optimization, and correlation activities. • Improve test coverage, test time efficiency, and manufacturability to support high-volume production. Test Hardware & System Integration • Lead the design, validation, and qualification of DUT boards, interface hardware, load boards, and test fixtures. • Lead hardware bring-up, system integration, and debugging activities. • Perform tester-to-tester, site-to-site, and platform correlation studies. • Conduct engineering evaluations and characterize test system performance. Validation & Change Management • Lead validation of hardware and software changes for test systems. • Execute qualification plans and document results for test releases. • Ensure all changes comply with engineering and quality requirements. • Maintain test documentation, procedures, and release records. Cross-Functional Collaboration • Work closely with Product Engineering, Design Engineering, Manufacturing, Quality, Equipment Engineering, and OSAT partners. • Lead technical discussions, design reviews, and test strategy development. • Participate in problem-solving and continuous improvement initiatives across manufacturing operations. Qualifications & Requirements: Minimum Qualifications • Bachelor's Degree in Electrical Engineering, Electronics Engineering, Computer Engineering, Mechatronics Engineering, or related disciplines. • At least 5 years of experience in semiconductor test, automation, manufacturing engineering, or related technical fields. Technical Skills • Basic understanding of semiconductor device testing and electronic measurement techniques. • Programming knowledge in C/C++. • Familiarity with software development, scripting, debugging, and data analysis. • Understanding of analog, mixed-signal, or power electronics fundamentals. • Knowledge of statistical analysis and engineering problem-solving methodologies. Preferred Qualifications • Exposure to Eagle ETS88 or other ATE platforms. • Familiarity with oven-based trimming, calibration, or characterization systems. • Experience with instrumentation such as DMMs, oscilloscopes, power supplies, frequency counter, and switching systems. • Knowledge of data analysis tools such as JMP, Galaxy, Exensio, Power BI, or equivalent. • Exposure to Python or MATLAB is a plus. • Experience with lab projects involving hardware-software integration is advantageous.
