Job description

Job Overview:

The Arm on Arm team drives 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 cases to Arm. We also collaborate with the Lines of Business to ensure that what we have done is used publicly in support of our ecosystem partners.

We are looking for a team member who is keen to get involved at all levels of the stack, from racking and building prototype Arm servers to helping partners optimize their code for the latest microarchitecture and bug finding in the Linux kernel to promoting the use of AArch64 across Engineering.

Responsibilities:

Be the first point of contact for technical queries from partners, especially EDA software vendors, regarding porting code or services to Arm. You will be expected to see these through to resolution, potentially over an extended period.

Diagnose problems, identify compatibility or performance issues, and resolve them as appropriate. Recent examples include:

• Identifying bugs in the network protocol of a storage filer.
• Investigating unexpected performance regressions and developing solutions.
• Assessing the consistency of floating point math results on Arm and across other architectures.

Required Skills and Experience:

• Demonstrated problem-solving ability and commitment to achieving solutions.
• Wide programming expertise across system to application level in languages, particularly C.
• Knowledge of software optimization techniques.
• Experience in benchmarking to generate robust performance measurements.
• IT Infrastructure awareness: TCP/IP, DHCP & DNS, data center configuration.

Nice To Have Skills and Experience:

• Understanding of the EDA landscape and experience using related tools.
• Knowledge of Neoverse micro-architectures.
• Linux Kernel internals.
• IT Service operations.

In Return:

At Arm, we are guided by our core beliefs that reflect our creative culture and influence how we work together to surpass the ordinary and achieve the extraordinary.
