Job Title
Lead I/O Design Engineer
Role Summary
Design and deliver high-performance I/O IP for advanced SoCs, including GPIO, LVDS, DDR, SerDes support circuits, ESD protection, level shifters, buffers, and termination circuits. Work at transistor level through silicon bring-up to ensure robust, production-ready designs.
Collaborate with system, package, reliability, physical design and product teams; lead technical discussions and guide junior engineers to meet performance, signal integrity, and reliability targets.
Experience Level
Senior-level; typically 5β8 years of experience in Analog/Mixed-Signal or I/O circuit design.
Responsibilities
Accountable for specification, design, verification, and delivery of I/O circuits and supporting IP.
- Design and develop custom I/O circuits: GPIO, LVDS, LVCMOS, SSTL, HSTL, DDR interfaces, and SerDes support circuits.
- Perform transistor-level design and SPICE simulation in advanced CMOS nodes.
- Develop and optimize ESD protection, level shifters, input buffers, output drivers, and on-chip termination.
- Run pre-layout and post-layout simulations for functionality, timing, power, noise, and reliability.
- Perform signal integrity analysis, IBIS model generation, package-aware simulation, crosstalk and reflection analysis.
- Drive layout reviews and collaborate with physical design to meet performance targets and manufacturability checks.
- Support silicon bring-up, lab characterization, debugging, and production ramp activities.
- Produce and maintain design documentation, specifications, and verification reports.
Requirements
Key technical skills and hands-on tools experience required. Degree information is summarized separately below.
Must-have:
- 5β8 years in Analog/Mixed-Signal or I/O circuit design.
- Strong understanding of CMOS device physics and analog circuit fundamentals.
- Deep knowledge of I/O architectures, interface standards, and ESD design methodologies.
- Hands-on experience with Cadence Virtuoso and SPICE-based simulators (Spectre, HSPICE, FineSim).
- Experience with advanced technology nodes (preferred: 16nm / 7nm / 5nm).
- Familiarity with LVS, DRC, EMIR, reliability checks, process corners, Monte Carlo analysis and yield optimization.
- Experience with signal integrity workflows and IBIS model generation.
Nice-to-have:
- Experience with DDR4/DDR5, LPDDR, USB, PCIe, MIPI, Ethernet, SerDes, or related high-speed interfaces.
- Knowledge of package modeling, SI/PI analysis tools and ESD standards (HBM, CDM, IEC).
- Silicon validation and lab characterization experience.
- Scripting skills in Python, Perl, Tcl, or SKILL; familiarity with IBIS-AMI model generation.
- Experience in automotive, AI/ML, networking, mobile, or data center SoCs; exposure to functional safety or reliability requirements.
Education Requirements
Bachelor's or Master's degree in Electronics Engineering, Electrical Engineering, Microelectronics, or a related technical field.
