Enterprise Account Executive - Sovereign AI & Defence

Senior Enterprise Account Executive – Defence & National Security

London / Hybrid | Enterprise Technology Sales

We are partnering with a rapidly scaling UK technology business that is expanding its commercial presence across Defence, Government and Critical National Infrastructure.

The company provides advanced enterprise technology that enables highly regulated organisations to adopt and operationalise AI securely across complex and sensitive environments.

Following strong early commercial traction, they are looking to hire a Senior Enterprise Account Executive to develop strategic accounts across the UK public sector and national security ecosystem.

This is an opportunity to join at an early stage of commercial growth, working closely with senior leadership and technical teams to win large, strategically important customers.

The Role

You will own the development of major enterprise opportunities across UK Government, Defence, National Security and CNI, taking opportunities from initial engagement through technical evaluation, procurement and commercial close.

Responsibilities will include:

• Owning the full enterprise sales cycle across strategic public-sector accounts.
• Building and developing pipeline across Defence, Central Government, National Security and CNI.
• Identifying and engaging senior decision-makers across technology, security, transformation and programme leadership.
• Developing complex opportunities involving multiple technical, commercial and procurement stakeholders.
• Navigating public-sector procurement frameworks and extended enterprise buying cycles.
• Working closely with technical and product specialists throughout customer evaluation and solution design.
• Developing compelling commercial propositions around secure enterprise AI adoption and measurable operational outcomes.
• Negotiating and closing significant multi-year enterprise agreements.
• Building long-term strategic relationships capable of generating expansion opportunities across major accounts.

What We're Looking For

We are looking for an experienced enterprise seller with a strong understanding of how complex technology is bought within the UK public sector.

You could currently be working within enterprise software, cloud infrastructure, cybersecurity, data, AI or another complex technology environment.

Ideally, you will bring:

• A strong track record of enterprise technology sales into UK Government, MOD, Defence or CNI.
• Experience winning complex, high-value new business opportunities.
• Knowledge of UK public-sector procurement and commercial processes.
• Experience managing long and sophisticated sales cycles involving multiple stakeholder groups.
• Confidence engaging senior technology, security and programme decision-makers.
• The ability to translate technically complex solutions into clear business and operational value.
• A genuine new-business mentality and willingness to build opportunities rather than inherit established accounts.
• Experience working within a scale-up, high-growth technology company or entrepreneurial commercial environment would be advantageous.

Why Join?

This is a rare opportunity to join a highly ambitious UK technology company at an important stage of its commercial development.

You'll have the opportunity to:

• Build strategic relationships across some of the UK's most important government and defence organisations.
• Sell technology addressing major challenges around secure enterprise AI adoption.
• Work directly alongside senior leadership and highly experienced technical teams.
• Influence commercial strategy as the organisation scales.
• Join early enough to have genuine impact and participate in the company's future growth through equity.
