Job Description

We are seeking an experienced Senior Staff Engineer – Analog/Mixed-Signal Design with 10+ years of expertise in transistor-level analog IC design and a strong foundation in analog circuit design fundamentals. The ideal candidate has a proven track record of architecting, designing, integrating, and delivering complex analog IPs and mixed-signal subsystems from concept through production. Experience developing power management ICs is a plus.

As part of Renesas' $2.6B Power Business Unit, you will help develop next-generation analog and mixed-signal solutions for multi-phase controllers and power management products that enable AI infrastructure and hyperscale computing platforms.

Key Responsibilities

Architect, design, own, and deliver high-performance analog and mixed-signal IPs, including:
- Source/sink LDOs
- Positive and negative charge pumps
- Relaxation and other oscillator architectures
- Temperature sensors
- Current-sense circuits
- SAR ADCs
- Protection circuits (UVLO, OVLO, OCP, thermal protection, etc.)
- Core analog building blocks, including bandgap references, operational amplifiers, comparators, analog buffers, V-to-I converters, and high-speed level shifters
Drive innovative circuit architectures and design optimizations to meet challenging performance, power, area, yield, and reliability targets.
Lead analog IP development through the complete product lifecycle—from architecture and transistor-level implementation through silicon validation, production qualification, and manufacturing support.
Collaborate closely with layout engineers from floorplanning through chip-level integration, ensuring optimal analog layout, parasitic-aware design, and performance trade-offs.
Develop and optimize simulation methodologies across pre- and post-layout verification, balancing simulation accuracy, convergence, runtime, and debugging efficiency.
Establish and drive robust analog design methodologies, review processes, and quality checklists to maximize first-pass silicon success.
Define and review chip-level ESD, latch-up, and I/O protection strategies to ensure product robustness and reliability.
Mentor junior engineers and foster a culture of technical excellence across the team.
Lead or manage a small team of engineers, driving execution, mitigating technical risks, and delivering high-quality silicon on schedule.

Qualifications

Minimum

Qualifications

Bachelor's or Master's degree in Electrical Engineering or a related discipline.
10+ years of hands-on experience in analog and mixed-signal IC design.
Demonstrated ownership of complex transistor-level analog IP from specification through silicon validation.
Strong understanding of:
- Analog circuit design fundamentals
- Semiconductor device physics and transistor-level design
- Process corners, Monte Carlo analysis, mismatch, and noise
- Extraction, post-layout simulation, and parasitic optimization
- Analog layout techniques and layout-dependent effects (LDE)
- ESD, latch-up, and chip-level reliability considerations
Proven experience across the complete IC development lifecycle, including architecture, design, verification, silicon bring-up, debugging, qualification, and production support.
Strong technical leadership, mentoring, communication, and cross-functional collaboration skills, with a passion for building high-performing engineering teams.
