The opportunity.
Do you strive to make a difference in the National Security and Defence sector? Are you driven to support the innovation and transformational change that will enable UK Defence to utilize its data fully, unleashing its power at scale and speed, and ensuring that operational and business decisions are based on correct, timely, and trusted information? At Quantexa, we are.
This urge and desire to challenge ourselves and the industry is what drives us every day. At Quantexa, our culture is underpinned not only by our ability to build market-leading, AI-driven technology but also by creating real change across the UK Defence sector. It’s what has led us to support National Security and Defence on several key projects, and we won’t be stopping there. #UNSTOPPABLE
The UK Defence Sales Director will join a collaborative team looking to build on current relationships while also forging new ones. This position is central to the growth of our EMEA Public Sector – National Security & Defence team. Working with our Solution Engineering, Product, Marketing, Delivery, and Customer Success teams, you will be responsible for executing the sales go-to-market strategy, identifying new opportunities, building our pipeline, winning new deals, and meeting company targets.
What You’ll Be Doing.
Typical responsibilities include working with our VP of EMEA Public Sector, National Security & Defence Market Vertical Lead, and the Director of Government Solutions to define and execute the sales strategy and go-to-market plan for the UK Defence Sector. You will consistently deliver against sales targets and contribute to the overall growth of the business. Your role will be a combination of hunting and farming; we have a great pipeline that needs nurturing, but we also require someone with a hunting mentality to develop new clients.
You will be tasked with bringing together people from different teams, working with Solutions Engineers, Marketing, Delivery, Technology Account Partners, Alliances, and many other areas.
What You’ll Bring.
What makes you Q will help you to realize your full potential, flourish and enjoy what you do, while being recognized and rewarded with our broad range of benefits.
We Offer
We have one mission. To help businesses grow. To make data easier. And to make the world a better place. We’re not a start-up. Not anymore. But we’ve not been around that long either. What we are is a collection of bright, passionate minds harnessing complexities and helping our clients and their communities. One culture, made of many. Heading in one direction – the future.
It’s All About You.
We want you to feel welcome, valued, and respected - because it’s your individuality and passion that make you Q. We see that, and we celebrate it. That’s why we’re proud to be an Equal Opportunity Employer.
We are committed to fostering an inclusive and diverse work environment, continuously improving to ensure everyone belongs. Our recruitment process is designed to be inclusive and accessible. If you need any reasonable adjustments or accommodations, please let our Talent Acquisition Team know - we’re happy to assist.
No matter your race, beliefs, color, national origin, gender, sexual orientation, age, marital status, neurodiversity, or abilities—whoever you are—if you're a passionate, curious, and caring human eager to push the boundaries of what’s possible, we want to hear from you.
