Senior Software Engineer, Persistent Disk – IPU, Storage Offloads

About the role

MINIMUM QUALIFICATIONS:

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical

Engineering, or equivalent practical experience.

• 5 years of software development experience in C or C++ with a focus on

systems programming.

• Experience with low-level systems architecture: PCIe, DMA, IOMMU,

memory-mapped I/O (MMIO), and interrupt handling.

• Experience debugging on pre-silicon or early bring-up platforms using

hardware emulators (e.g., P3, CSS models) or physical logic analyzers/JTAG.

PREFERRED QUALIFICATIONS:

• Master’s degree or PhD in Engineering, Computer Science, or a related

technical field.

• Experience with custom SoC storage virtualization technologies (e.g.,

NVMe/SCSI controller emulation, VirtIO).

• Familiarity with storage data protection protocols, including block

cryptography and data integrity validation (logical block addressing (LBA)

mapping, cryptographic hashes).

• Understanding of hardware-level security architectures.

ABOUT THE JOB:

Google's software engineers develop the next-generation technologies that change

how billions of users connect, explore, and interact with information and one

another. Our products need to handle information at massive scale, and extend

well beyond web search. We're looking for engineers who bring fresh ideas from

all areas, including information retrieval, distributed computing, large-scale

system design, networking and data storage, security, artificial intelligence,

natural language processing, UI design and mobile; the list goes on and is

growing every day. As a software engineer, you will work on a specific project

critical to Google’s needs with opportunities to switch teams and projects as

you and our fast-paced business grow and evolve. We need our engineers to be

versatile, display leadership qualities and be enthusiastic to take on new

problems across the full-stack as we continue to push technology forward.

With your technical expertise you will manage project priorities, deadlines, and

deliverables. You will design, develop, test, deploy, maintain, and enhance

software solutions.

As a Senior Software Engineer for the IPU Storage Offloads team, you will design

and implement the low-level software and firmware that powers Google’s

next-generation Infrastructure Processing Unit (IPU). You will focus on the

Persistent Disk (PD) data path, enabling high-performance NVMe emulation,

hardware compression/decompression, and hardware-accelerated cryptography.

You will bridge the gap between ASIC capabilities and core block-storage

services to deliver unprecedented Input/Output Operations per Second (IOPS) and

latency metrics while guaranteeing end-to-end data integrity and

confidentiality.Behind everything our users see online is the architecture built

by the Technical Infrastructure team to keep it running. From developing and

maintaining our data centers to building the next generation of Google

platforms, we make Google's product portfolio possible. We're proud to be our

engineers' engineers and love voiding warranties by taking things apart so we

can rebuild them. We keep our networks up and running, ensuring our users have

the best and fastest experience possible.Individual pay is determined by factors

including job-related skills, experience, and relevant education or training.

US: $174000 - $252000 (USD) + 15% bonus target + equity + benefits

RESPONSIBILITIES:

• Develop low-level drivers and kernel-level modules.
• Develop embedded C++ services running natively on ARM CPU cores to manage

storage queues, ring buffers, and Peripheral Component Interconnect Express

(PCIe)/Direct Memory Access (DMA) controllers.

• Optimize the data-path for microsecond-level latency and millions of IOPS

using advanced hardware features like physical doorbells and direct cache

routing.
