Overview

Impact
Profile match
Arm Holdings is a British semiconductor and software design company headquartered in Cambridge, England. Rather than manufacturing physical chips directly, Arm designs energy-efficient central processing unit (CPU) architectures and intellectual property (IP), licensing them to major technology partners such as Apple, Qualcomm, Samsung, and Nvidia.

This is a fantastic opportunity to work on the next generation of processors for multiple applications - mobile, laptop, servers, IoT and automotive to name a few!

Job Overview:

Meeting Area, Frequency and Power requirements are some of the most meaningful activities in CPU development. We work closely with micro-architecture designers and standards cells/Macro designers to build and improve metrics and quality of designs, targeting 3nm and below technology nodes.

What could you be doing as a Physical Implementation Engineer?

As member of the CPU implementation team, you will work to identify critical paths, timing and power improvement opportunities across IP development, enabling accurate trade-off between the various performance metrics of the designs (frequency, IPC, power, area).

We are looking for individuals who:

Are graduated from a University or Engineering School, in Electronic Engineering or Computer Science and with a prior experience of 3to 6 years in a similar field. We are also looking for:

  • experience on synthesis/clock tree, place and route tools and techniques
  • understanding of Power versus Performance versus Area tradeoff in typical CMOS design
  • knowledge about CPU micro-architecture concepts (cache, MMU, pipeline…)

Qualities that will help your application stand out:

  • Good interpersonal skills
  • Experience of developing scripts (Python, Perl, Tcl …), working in UNIX/Linux environment, code versioning with GIT

Additional Information

We encourage early applications as we review them on a first come/first served basis.

In Return:

In addition to a competitive salary andcomprehensive rewards package, you'll also receive the support, autonomy and opportunity to excel in your career.

With a mid-year, and year-end review you'll have two windows each year to progress recognizing the pace at which you could grow. Attend our 'Grad-teach-Grads' workshops, guest speaker series and various social events to expand your knowledge. Want to take this a step further? Join our Graduate Committee and home in on your planning, networking and co-ordination skills.

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.

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.
