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
The Principal Test Development Engineer is the main focal point in the development of a test solution, capable of deciding the technical direction and strategy of the test design and its implementation.

From the initial product development kickoff through end-of-life, the ATE Test Development Engineer defines ATE test hardware and software and supports the launch of new products into high-volume production. This includes board-level hardware design, algorithm development, software implementation, and validation on both custom and standard automated test equipment (ATE) platforms.
Responsibilities:
Test Solution Development
- Define the ATE test flow and test plan for new products
- Engage with design team on Design for Test (DFT) features
- Develop, validate, and release production test software for standard mixed-signal ATE platforms such as Teradyne Eagle Test Systems (ETS-88).
- Provide critical inputs in the development of the test hardware from block diagram definition, schematic drafting, layout considerations, assembly, and verification.
- Support new product introduction (NPI) activities by developing test methodologies and qualification or characterization plans.
- Participate in test program debugging, optimization, and correlation activities.
- Improve test coverage, test time efficiency, and manufacturability to support high-volume production.
- Lead release-to-production activities, including support for high-volume production.
Test Hardware & System Integration
- Assist in the design, validation, and qualification of DUT boards, interface hardware, load boards, and test fixtures.
- Support 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
- Support 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.
- Support technical discussions, design reviews, and test strategy development.
- Participate in problem-solving and continuous improvement initiatives across manufacturing operations.
Technical Leadership
- Serve as the technical lead of a project, providing guidance and assistance in technical discussions
- Mentor and train junior engineers, associates, and technicians
Qualifications & Requirements:
- Minimum of a BS degree in Electrical Engineering or equivalent experience.
- At least eight years of related work experience as an individual contributor focusing on key technical areas.
- Background in ATE development for mixed-signal ICs, including hands-on experience with ATE platforms such as Teradyne's ETS-364, ETS-88, or UltraFLEX is preferred but not required.
- Knowledge of analog electronics and experience with board-level troubleshooting and debugging.
- Experience in statistical analysis of test data.
- Hands-on experience with electronics lab instrumentation; prior experience with metrology systems for evaluating timing parameters is preferred but not required.
- Excellent programming skills and prior experience with C++.
It is not necessary to meet all job requirements to be a qualified candidate for the position.
Desired Characteristics & Attributes:
- High level of self-motivation and drive to make an impact.
- Strong interpersonal and mentorship skills for engineers on the team.
- Strong sense of ownership, drive for results, and ability to bring items to the finish line.
- Strong interest in being hands-on in the lab.
- Ability and willingness to work in a highly collaborative, fast-paced team environment.
- Excellent analytical and problem-solving skills.
- Excellent written and verbal communication skills.
- Positive attitude and motivation to learn new skills.
