Principal Power/Performance Engineer

Job ID 2025-13984 Date posted Apr. 25, 2025 Location Cambridge, United Kingdom Category Hardware Engineering Apply

Job Overview:

Our team investigates how consumer-focused devices deliver outstanding performance within constrained power and thermal budgets. We're growing, and looking for an engineering leader to bring their experience in power efficiency analysis to a new challenge at Arm.

The data we measure on phones and laptops under test is used by architects, engineering teams and product managers to make our future products even better. We always keep in mind the end use of our benchmarking results, working collaboratively to produce extraordinary outcomes for Arm and our partners.

Responsibilities:

The engineering leader joining our team would exercise considerable freedom to experiment and find knowledge gaps we need to close. A typical day would include:

  • Planning work from hypothesis to insight, with scope to adapt critical use cases and workloads to get the data required.
  • Leading efforts analysing power traces to produce power efficiency data, making this repeatable for others on the team.
  • Presenting our data and interests in a compelling manner in discussions with Partners and other teams in Arm.

Required Skills and Experience :

We spend considerable effort to collect and refine data from consumer grade devices (aimed at people rather than engineers). We need our leaders in this domain to make the complicated simple, bringing the following experience and skills:

  • Well-used strategies for handling experiments spanning many variables, working through ambiguity to bring clarity to both strategy and outcomes.
  • A tenacious approach to problem solving, with the ability to adapt or write new microbenchmarks to specifically target experiment outcomes where required.
  • Excellent technical communication skills for a range of audiences, from written reports to more traditional tech presentations.

“Nice To Have” Skills and Experience :

The following are things that we would be looking for in our ideal new team member:

  • Is self-motivated and always thinking of ways to improve how we work.
  • Is proficient at using tools such as Python to post-process data, produce statistical summaries and performance reports. Bonus points if this is flexible enough to be reused over and over again!
  • Experience in leadership, coaching, mentoring or line management.

In Return:

Beyond getting to experiment on the latest consumer devices on the market? The insights you and the team uncover will guide our future product development direction so you will have a substantial positive impact on bringing amazing new technology to billions of people!
