About the Role

We are seeking a Senior NVM Design Engineer with 15+ years of industry experience in OTP and/or EEPROM memory design to lead the architecture, design, and delivery of high-quality non-volatile memory IPs. This role requires deep technical expertise, strong cross-functional leadership, and ownership of NVM IPs from concept through silicon qualification and production release.

What You’ll Do

Architecture & Design

Lead architecture definition and circuit design of OTP and EEPROM memory IPs, including bit-cell, periphery, high-voltage devices, charge pumps, sense amplifiers, and write/erase control.
Define programming algorithms, redundancy schemes, reliability mechanisms, and safety features.
Drive PPA (Power, Performance, Area) optimization across multiple technology nodes.
Own top-level NVM IP micro-architecture, including interfaces to digital controllers and test logic.

Implementation & Silicon Execution

Oversee schematic design, simulation, and verification (functional, corner, Monte-Carlo, aging).
Partner closely with layout teams to ensure DRC/LVS clean, robust HV-aware layouts with strong EM/IR and reliability margins.
Support DFT, BIST, IJTAG, and test-mode implementation, including fuse evaluation and trimming flows.
Drive silicon bring-up, debug, and characterization, including programming window optimization and yield learning.
Define and support qualification strategies (HTOL, bake, cycling, retention, endurance).
Work with Quality & Reliability teams to ensure product readiness and cost-effective qualification.
Own failure analysis and root-cause resolution for NVM-related issues.

Cross-Functional Leadership

Act as technical lead interfacing with Technology Development, Digital Design, Validation, Product, and Foundry partners.
Mentor junior and mid-level designers; establish best practices and design methodology for NVM IP.
Contribute to multi-generation NVM roadmaps and technology scaling strategies.

Required Qualifications

Bachelor’s or Master’s degree in Electrical Engineering or related field.
15+ years of hands-on experience in OTP and/or EEPROM memory design.
Strong expertise in:NVM bit-cell and peripheral circuit design
High-voltage devices and reliability-aware design
Programming/erase algorithms and margin analysis
Silicon debug and characterization
Proficiency with SPICE simulation, corner analysis, and statistical modeling.
Experience working across multiple process nodes and foundry technologies.

Preferred Qualifications

Experience with both OTP and EEPROM (cell-based or fuse-based implementations).
Familiarity with automotive or safety-critical requirements (AEC-Q100, ISO-26262).
Exposure to NVM controllers, digital interfaces, and test vehicles.
Prior experience leading IP tape-outs and production releases.
Strong documentation and technical review skills.
