Director Memory Design
Kepler
Ultra-low-voltage computing hardware and memory
About the Role
We’re looking for a technically deep Director, Memory Design to own memory controller design for Kepler’s memory products. The role sits where memory architecture, digital logic design and system integration meet. You’ll bring hands-on expertise in memory controller architecture and RTL design, low-latency access path design and memory subsystem optimization for AI workloads. You’ll both architect and implement, making sound VLSI trade-offs throughout.
Key Responsibilities
Own memory controller design end to end, from architecture to tapeout, including low-latency memory access paths and high-bandwidth interfaces.
Write and maintain high-quality SystemVerilog RTL. Drive PPA optimization and implementation convergence (lint, CDC/RDC, LEC, synthesis, timing closure).
Define and review functional and formal verification plans, validate SDC timing constraints, and ensure design quality through rigorous reviews.
Work closely with architecture, physical design and post-silicon validation teams.
Lead the investigation and fixing of complex timing violations and structural design issues during physical implementation.
Define and drive adoption of new design methods that improve power efficiency in high-bandwidth memory interfaces.
Set design best practices, keep technical documentation current, and mentor engineers.
Requirements
B.Tech/M.Tech/MS/PhD in Electrical/Computer Engineering or a related field.
15+ years in memory controller architecture and RTL design, including multiple successful SoC tapeouts.
Expert knowledge of memory controller design: scheduling, ECC, refresh, power management and training.
Strong understanding of industry-standard memory protocols and VLSI trade-offs across latency, bandwidth, power and area.
Skilled in SystemVerilog, front-end flows (synthesis, CDC, formal verification) and scripting (Python, Perl, Tcl).
Experience with memory controller performance modeling: simulation, queue-depth analysis and scheduler evaluation.
Deep hands-on timing closure experience on complex, high-frequency digital blocks.
Proven record of leading design teams through at least three full-chip tapeouts in advanced process technologies.
Proven ability to work across teams and deliver complex design blocks with small teams.
Nice to Have
Experience with 3D innovations
Experience developing custom memory interfaces.
Familiarity with memory access patterns in AI workloads.
Experience with low-power design techniques such as power gating, DVFS and multi-VT optimization.
Familiarity with DFT architectures and methods for high-speed memory interfaces.
Compensation and Benefits
Actual compensation will be determined based on factors including, but not limited to, relevant experience, skills, qualifications, education, job responsibilities and work location.
Kepler offers a comprehensive benefits package to eligible employees, including medical, dental and vision coverage, retirement benefits, time off and additional Kepler benefits as applicable. Eligibility and benefit offerings may vary based on employment status and work location.

Kepler Computing, Inc. develops energy-efficient computing hardware with an ultra-low voltage architecture for memory and logic. Its products include 3D stacked compute and memory units, majority logic gates using input paraelectric capacitors, low-power sequential circuits, and memory bit-cells based on non-linear polar materials. The design uses multi-node, heterogeneous technologies to boost computational power while lowering energy consumption, aiming to outperform traditional silicon-based solutions. Kepler differentiates itself by integrating novel materials (ferroelectric/non-linear polar materials), paraelectric capacitor-based logic, and 3D stacked memory in compact, low-power blocks rather than relying on conventional silicon scaling. Its goal is to deliver more powerful computing hardware that consumes less energy, enabling high-performance computing with significantly improved energy efficiency.
