The Team You’ll Be A Part Of

You’ll join a team focused on DDR/LPDDR PHY and high-speed I/O circuit design, working alongside experienced analog and mixed-signal circuit designers. You’ll gain hands-on exposure to production-level PHY development, advanced semiconductor technologies, and modern IC design methodologies while receiving mentorship from experienced engineers.

What You’ll Be Doing

- Assist with transistor-level design and simulation of DDR I/O circuits.
- Analyze timing, power, signal integrity, and PVT variations.
- Contribute to the design and functional verification of TX, RX, clocking, calibration, and power-delivery circuits.
- Develop simulation testbenches and automate result analysis.
- Debug schematic, layout, and post-layout simulation results.
- Document technical findings and present results to the design team.
- Gain hands-on experience with production DDR/LPDDR PHY development and advanced semiconductor design methodologies.

The Impact You Will Have

- Contribute to the development and characterization of high-performance DDR/LPDDR PHY circuits.
- Support analysis and verification activities that help ensure circuit performance across different operating conditions.
- Help improve simulation and analysis efficiency through testbench development and automation.
- Contribute to identifying and resolving circuit-level issues through schematic, layout, and post-layout analysis.
- Build practical analog and mixed-signal IC design experience while contributing to real-world semiconductor development.

What You’ll Need

- Currently pursuing a BS or MS in Electrical Engineering or a related discipline.
- Coursework in analog/mixed-signal IC design, CMOS circuits, or VLSI.
- Understanding of MOS device operation and basic circuit analysis.
- Familiarity with SPICE simulation.
- Scripting experience with Python, Perl, Tcl, or Shell.
- Strong analytical, debugging, and communication skills.
- Knowledge of DDR, LPDDR, or other high-speed interfaces is a plus.
- Experience with Cadence or Synopsys custom-design tools is a plus.
- Familiarity with signal integrity, clocking circuits, statistical analysis, or post-layout verification is a plus.
- Exposure to advanced-node CMOS design is a plus.
- Good written and spoken English skills, including the ability to read and write technical documentation
