Our portfolio spans autonomous coding agents, specialised AI models, AI-native red teaming and sovereign AI solutions.

This is a commercially driven, hands-on role. You'll own relationships, develop joint propositions, negotiate agreements and build customer pipeline.

Build joint account plans, identify customer opportunities and develop a qualified pipeline with clear commercial objectives. Work with partners and internal sales teams to progress opportunities into pilots, deployments and revenue. Take accountability for outcomes. Signed agreements matter, but active partners, customer engagements and revenue matter more. Create propositions that partners can sell Work with product, engineering and commercial teams to develop compelling joint propositions around sovereign AI, coding agents, software modernisation and cybersecurity. Understand partner capabilities and customer challenges, identifying where Cosine's technology creates real commercial value. Translate complex technology into clear, differentiated propositions that partners can confidently take to market. Get hands-on and make things happen Run product demonstrations, partner workshops and enablement sessions. You'll need to understand our technology, not just talk about it. Equip partner teams to identify opportunities, position Cosine effectively and engage customers. Navigate commercial, technical and organisational challenges to keep deals moving. Build the processes, reporting and partner engagement model needed to scale what works, without creating unnecessary bureaucracy. ___________________________________________________________________________ What we’re looking for We want someone who has built partnerships that generate business, not simply managed relationships. You'll bring: A proven commercial track record. Demonstrable success building partnerships, developing pipeline and delivering revenue within enterprise technology, software or AI. Strong SI and consultancy experience. You understand how these organisations operate, how to navigate their internal structures and what it takes to turn strategic alignment into real customer opportunities. Commercial sharpness. You know how to qualify opportunities, negotiate agreements, develop compelling commercial propositions and focus effort where it delivers the greatest return. Technical credibility. You're comfortable engaging with complex enterprise technology, running product demonstrations and holding meaningful conversations with technical stakeholders. You don't need to be an engineer, but you must be capable of getting under the skin of our products. Executive-level relationship skills. You can engage confidently with senior decision-makers, build credibility quickly and influence stakeholders across large organisations. Relentless execution. You're proactive, resourceful and commercially driven. You take ownership, follow through and don't need someone else to create momen
