About The Position

We are seeking a curious, motivated, and talented Principal Product Engineer to accelerate the development and deployment of SiTime’s MEMS-based timing products. The Principal Product Engineer will be responsible for driving continuous improvements on one or more products in production to ensure high yield and high quality while reducing product cost. This role expects the engineer to be adept at utilizing statistical methods for analyzing large datasets to identify yield issues and work with cross-functional engineering team members to resolve them. This position is ideal for an engineer with strong analytical capability, deep understanding of semiconductor/MEMS device behavior, and experience maintaining complex mixed-signal or MEMS products in mass production. Candidates with experience in Systems Engineering, Silicon Characterization, Circuit Design or MEMS Design are preferred. Qualified candidates can be a graduate in Electrical Engineering, Mechanical Engineering, Computer Science or equivalent.

Requirements

Bachelor’s or Master’s in Electrical Engineering, Mechanical Engineering, Materials Science, Physics, or related field.
7+ years of experience in Product Engineering, Semiconductor Device Engineering, or MEMS technology.
Proficiency in data analysis tools (e.g., Exensio, JMP, MATLAB, Python).
Experience with high-volume manufacturing, ATE test flows, and statistical process control (SPC).
Demonstrated ability to drive cross-functional technical initiatives to closure.

Nice To Haves

Strong understanding of MEMS resonators, timing architectures, oscillators, or mixed-signal ICs.
Experience with MEMS fabrication processes, wafer-level packaging, or thin-film materials.
Background in timing products (TCXO/OCXO/MEMS oscillators).
Familiarity with failure analysis techniques such as SEM, FIB, XRD, and electrical debug.
Experience with automotive or industrial qualification standards.

Responsibilities

Lead product engineering activities from concept through high-volume ramp for MEMS oscillators, resonators, and timing ICs.
Analyze large datasets to assess product performance across process, voltage, temperature, and reliability stresses.
Partner with test engineering to develop efficient and robust production test solutions.
Drive root-cause analyses and problem-solving for device performance and yield issues during development.
Monitor production performance, yields, and outgoing quality; identify trends and drive continuous improvement actions.
Collaborate with foundry, assembly, and test partners to resolve process and equipment-related issues.
Implement design-of-experiments (DOE) to optimize parameters, improve yield, and reduce test cost.
Ensure robust product release through documentation, risk assessments, and data-driven decision-making.
Support customer engineering teams with debug, field returns, and technical inquiries.
Interface with operations for supply chain readiness, lifecycle management, and cost-reduction initiatives.
