Strategic Account Lead, National Security

Plexal operates at the intersection of government, industry and emerging technology — helping organisations turn innovation ambition into practical capability, adoption and measurable impact. National Security is a core growth area for Plexal’s Innovation Services business, where we support government clients to adopt new technology, build innovation ecosystems and respond to emerging threats and opportunities.

The Strategic Account Lead will drive commercial growth and strategic client engagement across London’s National Security landscape. This role blends relationship based sales, delivery aligned growth and proposition development. You will build strong partnerships with government and secure market clients, shape new opportunities, and help evolve Plexal’s offering in a rapidly changing environment.

This is a hands‑on commercial role suited to a growth‑minded consultant who enjoys building relationships, and wants to influence how emerging technology is adopted across secure‑government markets.

• Drive net new business and diversification, identifying and developing new revenue opportunities, expanding engagement across client business units, and landing multi year, high value contracts.
• Leverage delivery engagement to deepen client relationships, strengthen Plexal’s reputation, and uncover new growth opportunities.
• Build strong and trusting client relationships though successful delivery on contract, create high levels of client satisfaction.
• Develop and refine propositions that respond to client needs, market trends and emerging technology opportunities, working closely with the wider National Security & Defence team.
• Partner with suppliers and ecosystem organisations to shape consortium bids, unlock new routes to market and build collaborative commercial opportunities.
• Provide insight into market trends, procurement behaviours and customer priorities to inform Plexal’s National Security account strategy.

• Highly relational, with excellent interpersonal skills and the ability to build trust quickly.
• Strategic thinker able to understand long‑term client trends and translate them into credible propositions.
• Growth‑minded — motivated by building new opportunities, expanding relationships and shaping commercial direction.
• Comfortable taking ownership and driving outcomes independently.
• Collaborative, supportive and aligned to Plexal’s culture of partnership and innovation.

Essential

• Strong consultancy sector background, with the ability to operate across strategy, delivery oversight and hands‑on opportunity execution.
• Strong understanding of government procurement, commercial processes and how secure‑government organisations buy and adopt technology.
• Ability to operate autonomously while collaborating effectively across GTM, delivery and London‑based teams.
