Staff Software Engineer - Storage

Job Overview:

The Open-Source Software (OSS) team is responsible for developing and improving the software ecosystem around Arm's next generation of applications processors. This frequently means working with processors and other hardware technology not yet available to the public.

We work on a range of development platforms, software-models, FPGAs and early silicon, sometimes many months before the processors are used in real products.

You will have the opportunity to improve your knowledge and expertise, provide optimizations to open source components (SPDK, Ceph, ROOK, OpenEBS, etc) of storage stack and build reference solutions on Arm. These contributions will help drive the development of sophisticated storage software stacks that form the basis for future solutions. We seek individuals with exposure and knowledge of every layer of the storage software stack ranging from kernel, common libraries and algorithms, distributed storage components and solutions. If you are similarly passionate about innovative technologies, then we would love to hear from you!

Responsibilities:

• Collaborate with internal/external partners to understand storage related requirements on Arm servers.
• Work with Arm internal teams and external partners to identify missing SW blocks and bottlenecks, enable and optimize related storage SW stack on Arm servers.
• Work with open source communities to upstream patches and maintain code.
• Collaborate with other architects/engineers to influence Arm technology.

Required Skills and Experience:

• Bachelors, Masters, or Ph.D. degree in Electrical Engineering, Computer Engineering, Computer Science or established experience in storage software development and optimization.
• Proficiency in C/C++/Assembly, experience in other programming languages, e.g. Java, Go, Python, etc is a good plus.
• Experience in at least one of the following areas: PCIe, CXL, block storage, object storage, and file system.
• Decent understanding of modern CPU architecture. A familiarity with concepts such as pipelines, caches, MMU and NUMA, and how these hardware facts impact high-level software performance.
• Expertise in debugging and optimizing sophisticated software systems.
• As well as curiosity; demonstrates technical leadership, sharing knowledge and mentoring others.
• Clear and effective communication skills. Outstanding interpersonal and relationship building skills.
• Able to work in complex environments under pressure with teamwork spirit, collaborate with colleagues in other groups and sites, effective time-management and prioritization skills.

“Nice To Have” Skills and Experience:

• Good understanding of the AArch64 architecture.
• Experience with working with open-source communities. We value familiarity with open-source project development cycles and contribution processes.
• Understanding of I/O and networking and their impact on server-side application performance.
• Experience with kernel bypass (RDMA, DPDK, SPDK) would be looked upon favourably.
• Experience with cloud native technologies such as Kubernetes, CSI.
• Familiar with cloud storage system deployment techniques like Ansible.
• Familiar with testing methodology and test automation. An awareness about the value of CI and automated test system.
