The posting, as the company wrote it
Employment: Full-time
Arondite is a defence technology company building the foundational software and AI to power the autonomous age. Our aim is to revolutionise the way organisations harness robots, sensors and autonomous systems and use the data they generate. We are driven by our determination to help defend our collective democratic values and by our strong belief that an elite group of engineers can make a big difference. We are ambitious, well-funded and building for the long-term.
You will join Arondite at a pivotal moment in the company’s journey. Our company is being built by exceptional engineers - people who find high-impact and technically challenging work engaging and exciting, and who consistently deliver outsized impact. You will work within a team and collaborate with other brilliant minds to solve some of the world’s most important problems.
You will have ownership and autonomy from Day One. Arondite is extremely flat by design. From your first day, you will directly influence product functionality and direction of Cobalt development. We hire the best people and give them extremely high levels of autonomy; to deliver the critical missions our users are responsible for.
If you are motivated by our mission, the mission of our users and want to be part of a growing team of outstanding people, then we want to hear from you.
About the role
Our Business Development team forges the relationships that bring our innovations from concept to deployment. You will work relentlessly to find problems for us to solve, you’ll build partnerships with other companies, educate and engage with government stakeholders, and work closely with defence customers. You should have first-hand knowledge of the world of defence and national security. Importantly you should have significant experience in delivering effective sales or commercial processes that drive the revenue of a business.
This role demands strategic vision and hands-on execution - you will be the engine room driving the growth of the company within a team of high-performing, but mission driven team mates. The problems we’re solving are technically complex and ambitious, so you should be comfortable with technical detail. We don’t need you to be able to build product yourself, but you need to be able to work closely with engineers and to absorb information about, and be able to explain, our product to a range of stakeholders.
You must also be able to understand and contribute to the development of our product roadmap; taking signal from customers, synthesising information and identifying features that should be part of our offering.
If you're energised by complex strategic challenges and want to help define the future of defence technology, as part of a high performing team, this is your opportunity to make a lasting impact.
Your responsibilities will include:
Conduct Arondite’s business development and strategic engagement in one or more of the Land, Maritime, Air and Joint domains
Build and maintain relationships with stakeholders across the Army, Royal Navy, Royal Air Force, Cyber & Specialist Operations Command, PJHQ, DE&S, Dstl, UK Defence Innovation and adjacent organisations
Work across the Strategy & Partnerships team to develop relationships with UK primes, technology partners and other organisations that can accelerate access to programmes and users
Own your opportunities end to end, from origination and qualification through contract award, deployment and expansion
Run structured customer discovery to test demand, refine positioning and surface priority use cases in your domain
Work with Deployment Strategists to get Cobalt in front of users quickly and convert operational success into funded requirements
Identify and validate funding routes, contracting vehicles and procurement timelines for each opportunity
Work with internal teams to translate market signals into product insight, roadmap input and go-to-market recommendations
Lead pricing, proposals, bids and commercial negotiations, working with our commercial team
Represent Arondite credibly in meetings, exercises, events and external conversations with senior decision-makers
Share market intelligence and situational awareness across the team, and keep pipeline and stakeholder records accurate
Requirements
You should have:
Experience winning enterprise software, defence technology or complex public-sector deals in the UK defence or national security environment
Be a team player, that can operate above the norms of sales organisations, to deliver a customer experience and mission focus that is world class
A track record of originating and closing multi-year, seven-figure contracts with defence or government customers
A strong understanding of how UK defence or public-sector procurement, innovation funding and stakeholder engagement work in practice
Experience building and managing senior relationships across government, defence, industry or technology organisations
A track record of structuring and advancing partnerships in defence, public sector or other highly regulated environments
Strong commercial judgement, including business case development, pricing awareness, communication and presentation skills
The ability to work effectively in a fast-moving, high-growth company alongside engineers and technical teams
The confidence to engage with technical subject matter and explain complex products to a wide range of audiences
The ability to operate with high ownership and autonomy from day one
We know the ideal candidate may not match every line item exactly. If this role is close to your experience and you are motivated by the mission, we would still like to hear from you.
Nice to have:
Understanding of the unique considerations involved in deploying AI solutions in defence contexts
Experience selling AI or machine learning solutions in regulated environments
Familiarity with responsible AI, defence AI ethics or assurance frameworks
Knowledge of UK content considerations, industrial participation expectations or related contracting requirements
Awareness of export controls, security requirements and information-handling constraints relevant to defence work
Security clearance
We believe in working closely with defence customers. As a result, this role is likely to require you to hold a clearance or be willing to undergo UK security vetting to Security Check (SC) or above. This normally requires having continuous residency in the UK for at least 5 years.
Office vs hybrid working
We are focused on building a positive, collaborative engineering-driven culture. We therefore believe in making the office a friendly, comfortable and fun place to be, and we try to work from the office where possible. Of course, there are times when it makes sense for you to work from home and that's OK. You may also need to travel to visit customers, depending on your role. But in general you should only apply to join Arondite if you're excited to come into the office and work in person by default.
Application process
Generally, our interview process is comprised of the following stages:
CV submission with initial questions
Introductory Teams call (30-45 mins)
In-person panel interview (60 mins)
In-person scenario-based interview (90 mins)
Final interview with one of Arondite’s Founders (30 mins)
Benefits
Highly competitive base salary
Generous equity in EMI share options in a well-funded and growing startup
7% employer pension contribution
Free meals in the office every day
Private health and dental insurance
Cycle to work scheme
Relocation support
Visa sponsorship for extremely strong candidates
Access to any resources, equipment and training that you need to do your job in a world-class way
