Technical Leadership

This area assesses your ability to guide the technical direction of a team. It is not just about your coding skills, but about your ability to make high-level architectural decisions that support business growth.

Be ready to go over:

• System Architecture – How you design for scale and reliability.

As an Engineering Manager at Diageo, you will act as the primary bridge between technical execution and business strategy. Your day-to-day will involve driving the delivery of complex software projects, ensuring your team is aligned with the broader engineering roadmap, and collaborating closely with product managers and cross-functional stakeholders.

You will be responsible for the health and performance of your team, which involves active mentoring and the implementation of best practices for development, testing, and deployment. You will often find yourself navigating ambiguous problems where you must define the scope, set expectations, and lead your team to a solution that meets both technical requirements and business deadlines.
