• Decide what we pursue and what we walk away from, and defend those calls.
• Own pipeline hygiene, forecast accuracy and a defensible probability on every opportunity.
• Set the commercial rhythm across the territory: demonstrations, trials, exercises and industry events, with Marketing and your capture manager.
• Carry and deliver an annual order intake target.
• Lead and grow the territory team.

Requirements

• +5-10 years selling complex defence systems to state customers, the majority of it in UK&I.

• Ownership of at least one full path to contract, from requirement shaping through acquisitio
