Make job search work for you
Turn a broad, stressful search into a focused weekly routine.
We are looking for a CPU RTL Design Engineer to join our CPU team in Cambridge, to work on load/store and core cache systems for next-generation processors. This is a critical part of any modern CPU, with a significant impact on performance, power efficiency and area. As CPU technology continues to evolve, crafting increasingly sophisticated and efficient load/store and cache subsystem presents some of the most exciting and challenging problems in processor development.
You will join a highly skilled team working on complex microarchitectural challenges, with opportunities to influence design decisions and make a real difference to the quality and competitiveness of our products.
We're looking for engineers who want to tackle the challenges of designing sophisticated CPU load/store and cache systems, from initial microarchitecture through to RTL implementation, optimisation and design sign-off.
We value engineers who are curious, enjoy solving difficult problems, challenge existing approaches and are motivated by building excellent technology.
Responsibilities Developing microarchitectural specifications from architectural and product requirements. Tackling the challenges of load/store and cache design, exploring alternative microarchitectural solutions and making informed trade-offs between power, performance and area (PPA). Owning design blocks, from initial specification through to implementation and sign-off.
Working closely with architecture, verification, performance modelling and physical implementation teams to deliver high-quality IP. Required Skills and Experience Experience of RTL design and implementation using SystemVerilog or Verilog, ideally within CPU, GPU, DSP or other complex digital systems. Experience of developing micro architectures and hardware blocks or subsystems.
A good understanding of digital design principles, including pipelining, timing, frequency and power optimisation, with the ability to evaluate alternative design approaches and make data-driven trade-offs to meet PPArequirements. Experience of working through the hardware design lifecycle, from specification to design sign-off. Good communication skills.
Strong analytical and problem-solving skills, with the ability to investigate and resolve complex technical issues independently Nice-to-Have Skills and Experience Experience of CPU load/store and cache design, including one or more of cache coherency, memory ordering, virtual memory principles, with an understanding of how these interact with the wider processor microarchitecture and pipeline. Knowledge of synthesis, timing analysis and physical implementation considerations. Programming or scripting experience in languages such as Python, C or C++.
Experience of technical reviews and supporting the development of other engineers. An interest in using AI tools and modern engineering methodologies to improve design productivity and quality. In Return You’ll work alongside engineers on technical problems that influence the performance and efficiency of Arm’s future processors. You’ll have opportunities to own significant parts of a CPU, influence microarchitectural decisions and develop your technical expertise while contributing to products used around the world.
Additional Information If skilled worker sponsorship is required, Arm will meet costs associated with sponsorship for the employer only. All fees associated with the individual’s application e.g. visa application fee and Immigration Health Surcharge, will be the responsibility of the successful candidate.

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 accommodations@arm.com 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 accommodations@arm.com . 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.
