Senior Software Engineer

Job Overview

Join the Central Engineering - Software team as a Senior System QA Engineer, helping to validate complex Linux server and SoC platforms. You will develop automated tests and investigate system-level issues across hardware, firmware and software, contributing to reliable platform bring-up, performance and long-duration stability. This role offers the opportunity to work across processor, memory, I/O, networking, storage, power and thermal technologies, collaborating with engineering teams to turn challenging failures into clear, actionable findings.

Responsibilities

• Develop and maintain functional, performance, stress and stability tests for Linux server and SoC platforms.
• Create test automation, log-analysis tools and regression coverage using C/C++, Python and shell scripting.
• Validate and debug interactions across firmware, Linux kernel and device drivers, system management, networking, storage and hardware bring-up.
• Investigate failures found during system-level workloads and long-duration testing; gather evidence, identify likely root causes and communicate findings clearly to partner engineering teams.
• Exercise platform reliability, availability and serviceability features, telemetry, power and thermal behaviour, and reset and boot flows.
• Contribute to validation of memory, high-speed I/O, PCIe, NVMe, Ethernet, RDMA and accelerator-related workloads where relevant to the platform.

Required Skills and Experience

• Practical experience programming in C or C++ and using Python and shell scripting to develop test automation, analyse logs and support regression testing.
• Ability to validate and debug Linux-based server or SoC platforms across firmware, kernel, device drivers, system management and hardware bring-up; equivalent practical experience is welcome.
• Experience designing and running system-level functional, performance, stress or long-duration stability tests, with effective failure detection and root-cause analysis.
• Understanding of system architecture and behaviour across areas such as CPU and memory, cache coherency, DMA, NUMA, IOMMU/SMMU, PCIe, networking, storage, power or thermal management.

Nice-to-Have Skills and Experience

• Experience with BMC-based server management, secure boot, firmware authentication, boot-stage sequencing, watchdogs, reset flows, inter-processor communication or mailbox mechanisms.
• Knowledge of RAS validation across memory, interconnect, PCIe or accelerator subsystems, including use of telemetry such as performance counters, sensors and activity monitors.
• Experience with PCIe or NVMe validation, including raw block-device testing, storage performance testing or long-duration storage stress testing.
• Knowledge of high-speed Ethernet, RDMA, RoCEv2, MPI/CCL-style communication stacks, collective operations, or scale-up and scale-out communication architectures.
• Familiarity with AI/ML or accelerator validation, including PyTorch workloads, model execution, numerical-result comparison, benchmarking, workload automation or concurrent compute, memory, networking and I/O testing.

In Return

You will work on meaningful system validation challenges at the intersection of hardware and software, helping improve the reliability and performance of complex server and SoC platforms. The role provides broad technical exposure across Linux, firmware, platform management, networking, storage and accelerator technologies, alongside opportunities to deepen your debugging, automation and system-level validation expertise. You will collaborate with engineers across disciplines and see your work inform product quality and platform readiness.

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 as 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.
