Principal Mixed Signal Design Engineer

Job Title

Principal Mixed Signal Design Engineer

Role Summary

Senior individual contributor role in Analog Devices' Automatic Test Equipment (ATE) / Industrial team in Wilmington, MA. The engineer will lead mixed-signal IC architecture and implementation for high‑performance production-test and industrial applications, working on fine-line CMOS and high-speed bipolar technologies and on-chiplet system-level designs.

Experience Level

Senior — typically requires 7+ years of relevant industry experience in system design, architecture, and design integration.

Responsibilities

Key responsibilities include hands-on design, architectural leadership, and cross-team integration on mixed-signal high-speed ICs.

• Lead the design and architecture of complex mixed-signal systems to meet performance, reliability, and integration targets.
• Design wireline transmitters and receivers.
• Develop mixed‑mode Decision Feedback Equalizer (DFE) designs.
• Design and implement clock & data recovery (CDR) circuits.
• Collaborate on VCO and PLL design and optimization.
• Apply analog and digital wireline equalization techniques.
• Design custom high‑speed digital circuits for mixed-signal integration.
• Integrate IC designs with cross-functional system teams.
• Provide technical leadership, mentor junior engineers, and present results to stakeholders.

Requirements

Must-have technical skills, experience, and other requirements.

• Minimum of 7+ years of system design/architecture engineering and design integration experience.
• Proven experience in RF or high-speed CMOS and/or data converter design.
• Expertise with FinFET processes (e.g., 16nm, 5nm) or fine-line planar analog CMOS (e.g., 28nm).
• Experience with software-defined CMOS communications or radar system design.
• Proficiency in digitally-assisted high-speed analog design (analog + mixed-signal techniques).
• Strong presentation, technical writing, and communication skills.
• Willingness to travel approximately 10% of the time.
• Work that requires access to export‑controlled technical data may require U.S. citizenship, U.S. permanent residency, or export-license approval.

Nice-to-have

• Strong analytical and problem-solving abilities.
• Experience mentoring engineers and managing technical projects.
• Ability to adapt to rapidly changing technologies and methodologies.

Education Requirements

Bachelor of Science in Electrical Engineering (BSEE) is required; Master of Science in Electrical Engineering (MSEE) is preferred.
