Principal Mixed-Signal Design Engineer

Job Title

Principal Mixed-Signal Design Engineer

Role Summary

Lead architecture, design, verification, and delivery of high-performance mixed-signal circuits for automotive SerDes (GMSL) products. Work with cross-functional teams to define requirements, supervise layout and verification, and support lab characterization and production test development.

Position is based in Beaverton, OR or Colorado Springs, CO; this posting references the Colorado Springs location.

Experience Level

Senior — Principal-level role. Typical background: 10+ years of relevant mixed-signal/SerDes design experience.

Responsibilities

Design, verify, and deliver analog and mixed-signal SerDes components and support production.

• Develop system and circuit architectures; create and specify individual circuit blocks.
• Own analog/mixed-signal circuits through full product development lifecycle.
• Perform transistor-level circuit design, simulation, and verification for Rx equalizers, DFEs, CDRs, Tx drivers, VCO/PLL/dividers, bias circuits, and related blocks.
• Provide technical leadership on complex SerDes products and mentor engineering teams.
• Supervise layout activity and run post-layout simulations and extracted verification.
• Prepare documentation, conduct design reviews, and coordinate with cross-functional teams.
• Perform lab evaluation, characterization, and debug using oscilloscopes, signal generators, BERTs, logic analyzers, and data acquisition systems.
• Support development of production test and debug flows.

Requirements

Must-have technical skills and experience:

• Expertise in high-speed SerDes circuit design (Rx equalizers, DFEs, CDRs, Tx drivers, clock generation, biasing).
• Extensive experience with Cadence analog/mixed-signal design, simulation, layout, and verification flows.
• Strong transistor-level design intuition and analytical skills; experience with CMOS small/large-signal device models.
• Solid understanding of semiconductor device physics (CMOS transistors, diodes, MIM caps, integrated inductors, implanted resistors).
• Extensive circuit analysis skills including HF effects, model limitations, and temperature dependence.
• Hands-on lab experience characterizing and debugging mixed-signal SoCs.
• Experience with package and layout parasitics and extracted-simulation flows.
• Proven track record delivering products to market and providing technical leadership on complex projects.
• Clear written and verbal communication and effective teamwork skills.
• Willingness to travel (approximately 10%).
• Note: Non-U.S. citizens or non-permanent residents may require export licensing review for access to technical data.

Nice-to-have:

• Experience with video protocols (DisplayPort, CSI/DSI, HDMI, PCIe).
• Analog/digital behavioral modeling and design of digital control blocks.
• DSP design experience and Matlab proficiency (digital filters, decimators).
• Familiarity with automated digital design flows (Verilog, synthesis, place & route, STA).
• Prior team or project leadership experience.

Education Requirements

Master's degree in Electrical Engineering (MSEE) or equivalent is listed as the minimum qualification; the posting also accepts equivalent practical experience. Fields referenced include Electrical Engineering and related technical disciplines. Minimum practical experience indicated is approximately 10+ years.
