Janes equips defence, government, and industry leaders with objective, accurate, and shareable data and analysis. Our experts combine advanced technology with proven tradecraft to deliver validated and contextual intelligence to assess threats, accelerate decisions, and anticipate change with confidence. We deliver our intelligence with the flexibility to fuse it with multiple sources in any system, enrich AI solutions, or access it through our portal. 

Job purpose: 

Reporting to the Strategic Territory Director UK, the successful candidate will drive growth for Janes across UK Defence and National Security customers.

This senior individual-contributor role focuses on selling Janes’ software, data and intelligence solutions, creating and developing complex opportunities, and expanding customer adoption. The remit includes UK Defence and Intelligence customers, including the UK Army, Royal Navy, Royal Air Force and the Intelligence Community. Experience across every customer group is not expected: the portfolio and focus will be shaped around the successful candidate’s experience and strengths. The role will build on existing Enterprise Agreement Light (EAL) activity and develop opportunities for broader Enterprise Agreements (EAs) across UK Ministry of Defence and National Security organisations.

The post-holder will work with significant autonomy, bringing commercial judgement and credibility to complex government environments. This is an individual-contributor role with no direct people-management responsibility.
