When we put unexpected teams in the same room, we unleash bold thinking with the power to inspire life-changing medicines. In-person working gives us the platform we need to connect, work at pace and challenge perceptions. That's why we work, on average, a minimum of three days per week from the office. But that doesn't mean we're not flexible. We balance the expectation of being in the office while respecting individual flexibility. Join us in our unique and ambitious world.

At AstraZeneca, we embrace change and invest in technology to redefine healthcare. Our dynamic environment supports innovation through collaboration and creativity. With access to cutting-edge tools and a global network of experts, we drive meaningful change in predicting, preventing, and treating patient conditions. Our commitment to lifelong learning empowers us to make an impact worldwide.
