Principal Hardware Performance Specialist

Open 60d

Job Overview:

The Arm on Arm team is responsible for the move to Arm-based platforms for all the compute used at Arm in the delivery of our business, whether that is in our engineering compute clusters, enterprise workflows, or on colleagues laptops. We have the remit to do whatever is needed to make that migration happen, whether that's working with our partners in the supply chain across software vendors, hardware companies and cloud operators; ensuring our internal IT systems provide access to Arm-based compute, or helping individual teams within the company to migrate their specific use case to Arm. We also collaborate with our Business Units to ensure that what we have done is promoted publicly in support of our ecosystem partners.

We are looking for a team member to lead on performance optimisation, getting stuck in at low level to help ensure that workloads are making the most of the hardware they run on. This covers activities ranging from profiling on new Arm microarchitectures through supporting ISVs with tuning their code to delving into the Linux kernel where performance regressions are found. They will also be hands-on with our new compute platform at a low-level, developing and upstreaming new features.

Responsibilities:

Investigate and address internal engineering teams' reports of slower-than-expected tool execution.
Partner with third parties to help them understand why and where their code is underperforming, and provide advice on how to accelerate runtime.
Act as a point of reference for CPU and SoC product management, advising on future requirements based on experience with internal workloads.

Required Skills and Experience:

Demonstrated problem solving ability and commitment to driving issues through to resolution.
Wide (system to application level) programming expertise in a number of programming languages (particularly C).
Software optimisation techniques.
Experience of benchmarking to generate robust measurements of performance.
Solid understanding of performance optimisation libraries and tooling.
Appreciation of the software development lifecycle.

“Nice To Have” Skills and Experience:

Understanding of EDA landscape and ideally experience in using tools.
Knowledge of Neoverse micro-architectures!
Low-level system expertise (eg PCIe, UEFI, OpenBMC).
Linux Kernel internals.
Involvement in Open Source projects

In Return:

You will join a team at the heart of Arm's strategy with access to the latest silicon and deep links across the ecosystem. You’ll also have the opportunity to get involved in Arm's private cloud project, where we are driving a major change to the way that Arm runs on-prem infrastructure. The Engineering IT organisation is reinventing our approach to delivery, building on Arm's long heritage with Open Source software to become a team proud not just to operate but to develop and upstream code.

We have real ambition for what we can achieve and the right candidate will enjoy a central role in our objective: to build the future of compute, on Arm.

Use of AI in Your Application

At Arm, we embrace the benefits AI can bring, including in recruitment. You may use AI to support your preparation, such as improving the clarity of written responses, practicing interview questions, or learning more about our industry. However, your application, and interview responses must reflect your own thinking, experience, and abilities. We want to understand your authentic perspective, creativity, and approach to problem solving. As such, you may not use AI to complete assigned tasks as part of any assessments. If you plan to use AI-supported or assistive technologies as part of a reasonable adjustment, please contact [email protected] so we can support you.

Recruitment Adjustments and Accommodations

At Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email [email protected]. To note, by sending us the requested information, you consent to its use by Arm to arrange for appropriate accommodations. All accommodation or adjustment requests will be treated with confidentiality, and information concerning these requests will only be disclosed to the extent necessary to provide the accommodation. Although this is not an exhaustive list, examples of support include breaks between interviews, having documents read aloud, or office accessibility. Please email us about anything we can do to accommodate you during the recruitment process.

Hybrid Working

Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing the value of flexibility. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team’s needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.
