Sr. Engineer, Infrastructure PBC Layout

SiTime Corporation•Santa Clara, CA

About The Position

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 are seeking a hands-on Senior PCB Layout Engineer to own the physical implementation of complex printed circuit boards used in characterization, validation, automated test equipment (ATE), production test, and internal engineering platforms. This role partners closely with hardware, signal integrity, mechanical, manufacturing, and test engineers to translate schematics and design constraints into robust, manufacturable PCB layouts. The ideal candidate brings at least 10 years of practical layout experience, strong design judgment, and a proven record of releasing high-quality boards from placement through fabrication and assembly. It is not necessary to meet all job requirements to be a qualified candidate for the position.

Requirements

10+ years of hands-on PCB layout experience for complex, high-density electronic systems
Expert-level capability in at least one major PCB layout platform, such as Cadence Allegro, Altium Designer, and working familiarity across common PCB design and review tools
Demonstrated experience laying out multi-layer high-speed digital, mixed-signal, precision analog, RF, clock, and power designs
Strong knowledge of PCB stack-ups, materials, controlled impedance, differential routing, length matching, crosstalk mitigation, return paths, grounding, and power integrity fundamentals
Experience with fine-pitch BGAs, HDI, microvias, via-in-pad, blind/buried vias
Practical knowledge of PCB fabrication, assembly processes, component land patterns, solder-mask and paste-mask design, panelization, tolerances, and manufacturing documentation
Experience applying DFM, DFA, and DFT principles and working directly with fabrication and assembly suppliers
Ability to interpret schematics, mechanical drawings, PCB specifications, component datasheets, and constraint documents
Strong attention to detail, configuration discipline, and ability to manage multiple board releases and design revisions
Clear written and verbal communication skills and the ability to work effectively across engineering and manufacturing teams

Nice To Haves

Bachelor’s degree, technical certification, or equivalent practical experience in electronics, electrical engineering, PCB design, or a related field
Experience with boards used for semiconductor characterization, validation, ATE, production test, probe, or laboratory instrumentation
Familiarity with SI/PI review or simulation tools and the ability to interpret analysis results and implement layout changes
Knowledge of IPC-2221, IPC-7351, IPC-6012, IPC-A-600, IPC-A-610, or related PCB design and workmanship standards
Experience mentoring other PCB designers and improving layout libraries, workflows, checklists, or release processes
Experience with rigid-flex designs, thermal management, high-current power delivery, low-noise clocking, or low-jitter systems

Responsibilities

Own PCB layout from initial placement and routing through design review, fabrication release, assembly support, and post-build updates
Translate schematics, mechanical requirements, stack-ups, and electrical constraints into complete board layouts
Route dense mixed-signal, high-speed digital, precision analog, RF, clock, power, and control circuitry.
Create and maintain fabrication and assembly deliverables, including Gerber or ODB++ data, drill files, drawings, pick-and-place files, and manufacturing notes
Perform thorough design-rule checks and release-package reviews to ensure data accuracy and completeness
Implement controlled-impedance routing, differential pairs, length matching, return-path continuity, isolation, shielding, grounding, and power-distribution requirements
Collaborate with electrical and SI/PI engineers to apply routing constraints and incorporate simulation or review feedback
Develop practical placement and routing strategies for high-density interconnect, fine-pitch BGA, via-in-pad, blind and buried vias, and other advanced PCB technologies
Maintain component footprints, padstacks, symbols, and library data in accordance with IPC guidance and company standards
Conduct peer reviews and contribute to PCB layout checklists, standards, templates, and reusable design practices
Drive DFM, DFA, and DFT reviews with PCB fabrication, assembly, test, and supply-chain partners
Resolve fabrication and assembly questions, document deviations, and incorporate lessons learned into future layouts
Work closely with mechanical engineers on board outlines, component clearances, keep-outs, connector locations, thermal constraints, and enclosure integration
Support prototype bring-up and root-cause analysis by reviewing layout-related signal, power, thermal, assembly, and reliability issues
Communicate design status, trade-offs, risks, and release readiness clearly to project stakeholders
