Originally posted 17 August 2026 by the employer.
Join SiTime to develop production test solutions for MEMS-based precision timing devices.
About the role
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. This role involves supporting new product introduction (NPI) and test program development for MEMS-based precision timing devices.
What you'll do
- Develop, validate, and release production test programs for Eagle Test Systems (ETS88) and oven-based trimming/calibration systems.
- Lead test program debugging, optimization, and correlation activities.
- Lead the design, validation, and qualification of DUT boards, interface hardware, load boards, and test fixtures.
- Perform tester-to-tester, site-to-site, and platform correlation studies.
- Lead validation of hardware and software changes for test systems.
- Work closely with Product Engineering, Design Engineering, Manufacturing, Quality, Equipment Engineering, and OSAT partners.
What you'll need
- 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.
- 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.
Nice to have
- 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.
- Experience with lab projects involving hardware-software integration.
