Job Title
Analog/Mixed-Signal IC Design Engineer - Acacia
Role Summary
Member of a mixed-signal IC design team developing high-speed, high-accuracy analog circuits for optical transceivers. Work across IC design, layout, measurement and productization for ultra-deep sub-micron CMOS chips used in fiber-optic transmission systems.
Experience Level
Senior-level. Role expects experienced analog/mixed-signal engineers with substantial industry experience (senior-level, typically 7+ years).
Responsibilities
Design, verify and deliver analog/mixed-signal blocks for high-speed optical transceiver ASICs; lead complex design work and coordinate across disciplines.
- Architect, design, simulate, layout, measure and productize high-speed AMS CMOS circuits.
- Lead design efforts for large blocks on complex chips; track deliverables and schedules.
- Mentor and review work of junior engineers; participate in peer reviews and design methodology.
- Collaborate with digital/DSP, packaging, system and hardware teams to meet signal and power integrity requirements.
- Develop and validate laboratory test setups; analyze measurement data and iterate designs to meet specs.
Requirements
Technical must-haves and relevant domain experience. Degrees and degree-related experience requirements are listed under Education Requirements below.
- Proven experience in design, simulation and measurement of high-speed ICs in at least three of these areas: high-speed serial links (serdes, data converters), modeling for system link simulations, high-performance output drivers, PLLs, clock transmission/propagation, op-amps/programmable gain amplifiers, and equalization techniques.
- Experience with ultra-deep sub-micron CMOS AMS design and mixed-signal verification.
- Ability to lead complex block-level design, perform layout review, and ensure manufacturability and producibility.
- Hands-on measurement and lab validation experience, including test setup construction and ESD-aware practices.
- Strong problem-solving, communication, and cross-functional collaboration skills.
Education Requirements
Minimum qualification specified by employer: Bachelor’s degree plus 8 years related experience, Master’s degree plus 6 years related experience, or PhD plus 3 years related experience. The posting does not specify particular fields of study or certifications.
Preferred Qualifications
Relevant skills and technologies that improve fit for the role.
- Experience with electrical transceiver applications (backplane and cable communications).
- Experience with FinFET and GAA process technologies.
- High-frequency layout experience, including floorplanning, analog/digital routing, and passive components (inductors, transformers, transmission lines).
- Design-for-manufacturability experience: PVT characterization, electromigration, self-heating, and IR drop analysis.
- Familiarity with lab validation, ESD methodology, and test fixture construction.
- Experience with Cadence Virtuoso, Spectre/APS/SpectreX, Calibre, EMX, AMS simulation flows, and MATLAB.
