We're developing the UK's first sovereign frontier large language model, alongside specialised models trained for complex, high-stakes applications. Our technology can be deployed in highly secure environments, including fully air-gapped infrastructure, enabling organisations to adopt advanced AI without compromising control over their data or systems. We work with some of the world's most complex organisations across defence, financial services and other critical industries, helping them develop, customise and deploy AI capabilities that solve real operational problems. We're now looking to build a substantial presence in healthcare and life sciences. ___________________________________________________________________________ The Opportunity We're looking for an exceptional Founding Healthcare Lead to build and lead Cosine's healthcare and life sciences business from the ground up. This is an entrepreneurial role at the intersection of frontier AI, healthcare and commercial strategy. You'll identify where our technology can have the greatest impact, build relationships with leading healthcare organisations, and turn those opportunities into meaningful commercial partnerships. We're particularly interested in applying our capabilities to problems that require secure deployment, highly specialised AI models, complex data processing and deep integration with existing enterprise systems. You'll work directly with Cosine's leadership, researchers and engineers to shape our approach to the sector and help establish healthcare as one of our most important markets. This isn't a conventional sales role. You'll be expected to develop the strategy, originate opportunities, shape solutions and build a business. ___________________________________________________________________________ ## What you’ll do Build our healthcare business - Define and execute Cosine's go-to-market strategy across healthcare, pharmaceuticals, biotechnology and the wider life sciences ecosystem. - Identify the highest-value applications for Cosine's technology, particularly where generic AI solutions fall short. - Establish relationships with senior leaders across healthcare providers, pharmaceutical companies, research institutions and technology partners. - Build and own a pipeline of significant commercial opportunities, from initial engagement through to contracts and long-term partnerships.

We're not simply integrating third-party AI models. We're building and training our own models, developing the infrastructure to deploy them, and creating the agentic systems that make them useful. Build something from the ground up. You'll have the opportunity to define an entirely new business vertical, with meaningful influence over strategy, partnerships, product direction and commercial growth. Work on problems that matter. Healthcare and life sciences present some of the most important and technically challenging opportunities for AI, from accelerating research to improving the efficiency and resilience of critical systems. Work alongside exceptional people. You'll collaborate directly with a team of ML researchers, engineers and commercial leaders developing frontier AI technology and deploying it into some of the world's most demanding environments. Have real ownership. This is a founding role with significant autonomy, direct exposure to the leadership team and the opportunity to build a substantial business within Cosine. ___________________________________________________________________________ What Success Looks Like Within your first year, we'd expect you to have: - Established a clear, differentiated strategy for Cosine in healthcare and life sciences. - Developed strong relationships with a focused group of strategically important customers and partners. - Originated and closed our first significant commercial engagements in the sector. - Identified repeatable use cases and commercial offerings that can support sustained growth. - Established healthcare as a credible and scalable business vertical for Cosine. We're looking for someone who wants to do more than sell an existing product. We want someone excited by the opportunity to help define how frontier AI is developed, commercialised and deployed across healthcare. ___________________________________________________________________________ Cosine is an equal opportunity employer. We value diverse backgrounds, perspectives, and ways of thinking, and we’re committed to creating an inclusive and respectful workplace. We encourage applications from anyone who meets the role requirements, even if you don’t meet every single qualification. If you need reasonable adjustments at any stage of the hiring process, we’re happy to discuss them. ___________________________________________________________________________ ## Compensation, Benefits & Ways of Working We’re an in-office team, five days a week, by design. We believe the work we’re doing benefits from being together, collaborating closely, and building shared context. What you can expect: - Competitive salary, benchmarked to the market - Equity / share options, so you share in the upside you help create - 30 days’ holiday + bank holidays - Work hard in the office, collaborate closely, and switch off properly - Dog-friendly office — bring your dog to work - Weekly team breakfast & lunch - Monthly socials - Pension - High-quality equipment to do your best work We care about focus, sustainability, and doing great work — not performative overwork. We value people who show up, contribute thoughtfully, collaborate well with their colleagues, and then go home. This role won’t suit everyone. But if you’re looking for a fast-moving environment, close collaboration, and a team that takes both the work and work-life balance seriously, it’s a great place to be. ___________________________________________________________________________ Agency & Data Protection Notice To comply with UK GDPR and our internal data-protection and equal-opportunity obligations, we only accept candidate applications and agency submissions via our Applicant Tracking System (ATS).
