Experience could come from professional work, internships, academic projects, open-source contributions, or other practical software development.\nAn interest in machine learning software and how AI models run on different hardware is important. Some experience with, or exposure to, machine learning frameworks, runtime systems, compilers, GPU/compute software, or other performance-oriented technologies would be beneficial but is not essential.\nIn this role, you will contribute to developing, testing, and improving software across different parts of the machine learning software stack. Working alongside experienced engineers, you will help investigate functional and performance issues and contribute to solutions across runtimes, compilers, drivers, and hardware.\nGood analytical and problem-solving skills, a willingness to learn, and an interest in machine learning systems, AI acceleration, and performance optimisation will help you grow in the role.\nBeneficial but Not Required\nWe do not expect you to have experience across all the areas below. Relevant knowledge, practical experience, or exposure could include:\nMachine learning inference frameworks such as LiteRT, TensorFlow Lite, ONNX Runtime, or similar technologies\n\nGPU programming or compute technologies such as Vulkan, OpenCL, TOSA, or compute kernels\n\nMachine learning runtimes, compilers, drivers, or backend integration\n\nComputational graphs, operators, memory management, or model optimisation\n\nAhead-of-Time or Just-in-Time compilation\n\nBenchmarking, profiling, testing, or analysing software performance\n\nAutomated testing or CI/CD workflows\n\nAI-assisted development tools used responsibly to support software development, testing, and debugging\n\nWhat You Will Learn and Develop\nInterested in understanding what happens when a machine learning model moves from a framework through the software stack and onto hardware?\nThis role provides an opportunity to develop your skills in C++ software engineering, machine learning systems, and hardware-accelerated AI while working alongside experienced engineers.\nYou will gain exposure to machine learning inference engines and runtimes, compiler technologies, GPU and accelerator integration, model execution, performance optimisation, benchmarking, testing, and automated validation.\nAs your experience develops, you will have opportunities to take on increasingly complex engineering challenges and build a broader understanding of how machine learning frameworks, software, compilers, and hardware work together to deliver efficient AI experiences on Arm technology.\nWorking at Arm\nAt Arm, we want our people to learn, contribute, and grow while working on technologies shaping the future of AI and computing. The role offers opportunities for professional development, collaboration with colleagues across our global engineering community, and exposure to challenging technical problems with real-world impact.\nArm provides a comprehensive range of employee benefits and support designed to help our people thrive at work and beyond. Benefits vary by location and can include support for health and wellbeing, financial wellbeing, time away from work, and professional development.\nWe want our recruitment process to be accessible and inclusive. Reasonable accommodations are available throughout the recruitment process, and we encourage candidates who require support to let us know so that appropriate adjustments can be considered.\nIf Skilled Worker sponsorship is required, Arm will meet costs associated with sponsorship for the employer only. Fees associated with the individual’s application, such as the visa application fee and Immigration Health Surcharge, will be the responsibility of the successful candidate.\nOur 10x Mindset\nAt Arm, we believe progress happens when people are empowered to think bigger and push beyond what seems possible. Our 10x mindset is about curiosity, ambition and creating impact that will be used by millions. We learn fast, prioritise collaboration and turn bold ideas into real technology. We look for people who are inspired by this way of working and want to grow in an environment where bold ideas are welcomed. Discover how the 10x mindset shapes life at Arm: https://careers.arm.com/10x-mindset\nUse of AI in Your Application\nAt 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  so we can support you.\nRecruitment Adjustments and Accommodations\nAt Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email . 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.\nHybrid Working\nArm’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.\nEqual Opportunities\nArm is an equal opportunity employer, committed to providing an environment of mutual respect where equal opportunities are available to all applicants and colleagues.
