As Business Development Manager, you'll:

• Identify and develop organic growth opportunities across the Defence portfolio, working with existing customers, operational teams and internal stakeholders.

• Coordinate governance activities, including gate reviews, reporting and compliance with the Serco Management System (SMS) and Defence Growth Protocol.
• Work collaboratively with bid teams, technical specialists and operational colleagues to shape compelling customer solutions.
• Build and maintain strong relationships with Defence customers, internal stakeholders and SME partners.
• Represent Serco at customer meetings, conferences and industry events to help promote our Defence capabilities.
• Capture and apply lessons learned to continuously improve future opportunities and delivery.

You'll ideally have:

• Experience working within the UK Defence sector.

• Experience managing opportunities, projects or bids through structured governance processes.
• Strong stakeholder management skills with the ability to influence across a complex, matrix organisation.
