Job summary

SK hynix memory solutions America Inc. in San Jose, CA, seeks a driven Senior Signal Integrity Engineer to develop next‑generation SSD products. The role emphasizes hardware design and SI/PI for high‑speed interfaces such as PCIe Gen4/5/6, DDR4/5, and ONFI, with hands‑on lab measurements and simulation.

You will collaborate with SoC, FW, package and circuit teams, mentor engineers, and define design guidelines. A BS in Electrical Engineering and 3–8+ years of relevant experience are expected.

Qualifications

• BS in Electrical Engineering required; MS in Electrical Engineering is a plus.
• 3-8+ years of relevant working experience.
• High-speed SSD board designs, pre layout simulation, post layout simulation and design layout guide generation for PCIe Gen4/5/6, DDR4/5, LPDDR4/4x, NVIO and PDN.
• Strong fundamentals in 3D/2D EM simulation tools and transmission line theory.
• Required experience of EM field solvers, time and frequency domain simulation tools like Sigrity, Allegro, ADS, HFSS, SIWAVE, and HSPICE.
• Simulation followed by measurement correlation using Oscilloscope, VNA and TDR equipment.
• Excellent understanding of PCB design fundamentals: single end and differential signaling, cross talk (near end and far end), signal loss and impedance control.
• Excellent written and verbal communication.

Responsibilities

• Mentoring of engineers.
• Provide SI/PI expertise for SSD controller package (SoC) substrate design and SSD PCB design.
• Participate in the design of SSD products including design guidelines, reviewing designs, validation of designs and final reports of work designs.
• Support PCB back-end process: defining stack-up and HDI via technologies, part placement, setting routing constraints and reviews.
• Interface with cross functional teams to ensure the design meets system level requirements through verification/validation in the lab.
• Work closely with SoC, FW, package, and circuit design engineers.
• Documentation and communication to design, product and executive teams.
• Debug and root cause analysis at all product development stages, as well as customer escalations.
