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

We at SiTime take pride in being the only company in the market that offers MEMS-based timing solutions. Our MEMS dies are uniquely complemented by our CMOS dies in the same package. We use state-of-the-art analog and digital circuits to achieve very aggressive design specs for our timing solutions. Our precision timing products keep pushing the boundaries of the industry across all dimensions and are by far superior to our competition. This has enabled us to continuously gain market share.

This has been achieved by pushing the innovation boundaries in MEMS and CMOS. Consisting of analog and digital blocks, our CMOS dies present unique technical challenges. The digital portion of our chips has been growing in the past few years and is expected to grow more rapidly in the upcoming years as our functionality and features scale up. To address our unique technical challenges, we are looking for a strong Senior Logic Design Engineer with a solid background in key digital design and implementation areas. It is not necessary to meet all job requirements to be a qualified candidate for the position.

Responsibilities

• Developing micro-architecture specification of the logic circuit from reading and comprehending the Product Requirement Document (PRD).
• Developing the Register Transfer Level (RTL) design from the micro-architecture specification using Verilog or SystemVerilog as the HDL.
• Developing standalone test benches to verify the RTL behavior.
• Writing and verifying SystemVerilog Assertions (SVA) for a design.
• Writing timing constraints and clock definition for synthesis and place and route tools.
• Running industry-standard synthesis tools (e.g., Genus or Design Compiler) and being able to fix timing problems if they arise.
• Understanding various design tradeoffs including timing/area/power and knowing how to improve them.
• Reading and understanding the Static Timing Analysis (STA) reports from an industry-standard STA tool (e.g., Prime Time).
• Cross-functional interactions and communication with various teams within SiTime including analog, verification, backend, system, and test engineering teams.
• Post-Si bring-up, validation, and debugging.
  
  

Qualifications & Requirements

• Master’s degree in electrical engineering plus 5 years of relevant work experience in the industry.
• Excellent verbal and written communication skills in English.
• Proficient in Verilog and SystemVerilog.
• Expertise in digital logic design fundamentals such as clock divider circuits, multi-clock logic designs, CDC, FIFO, FSM, etc.
• Experience in designing mixed-signal digital logic.
• Basic understanding of Discrete time Signal Processing theory, FIR, and IIR filter design.
• Solid experience in digital design flow including RTL design, synthesis, timing constraints, and STA.
• Skilled in scripting languages Perl/Tcl/Python.
  
  

Desired Characteristics & Attributes

• Ph.D. in electrical/computer engineering plus 3 years of relevant industry experience.
• 2-5 years of experience in designing high-precision digital arithmetic logic and Digital Signal Processing.
• 2-5 years of experience in designing Digital Phase-Locked Loops (DPLL).
• Experience in complex FSM design.
• Familiarity with MATLAB, Simulink, or any other high-level modeling tools.
• Experience in low-power digital design flow.
• Basic understanding of the Control Theory.
