At Arm, we are guided by our core beliefs that reflect our rare culture and guide our decisions, defining how we work together to defy ordinary and shape extraordinary:

We not I

  • Take daily responsibility to make the Global Arm community thrive.
  • No individual owns the right answer. Brilliance is collective.
  • Information is crucial, share it.
  • Realise that we win when we collaborate — and that everyone misses out when we don’t.

Passion for progress

  • Our differences are our strength. Widen and mix up your network of connections.
  • Difficult things can take unexpected directions. Stick with it.
  • Make feedback positive and expansive, not negative and narrow.
  • The essence of progress is that it can’t stop. Grow with it and own your own progress.

Be your brilliant self

  • Be quirky not egocentric.
  • Recognise the power in saying ‘I don’t know’.
  • Make trust our default position.
  • Hold strong opinions lightly.

Arm has a responsibility to ensure that all employees are eligible to live and work in the UK.
