Job title: Technical GTM Lead Location: London; full in-office working as default Start date: ASAP Reports to: CRO Compensation: Salary and Equity options available for discussion Application deadline: 01/11/26 at 23:59 UK time ___________________________________________________________________________ Help put frontier AI to work in the real world Cosine is a UK AI lab building models, applications and training infrastructure for mission-critical organisations. We build coding agents that work across real software systems, specialised Lumen models, AI-native security products and the infrastructure needed to deploy advanced AI in demanding environments. Our customers include some of the world’s largest enterprises, including organisations operating behind strict security, regulatory and technical constraints. We’re also training Lumen Sovereign, the first frontier large language model trained in the UK, with the support of the UK Government. We’re now looking for a Technical GTM Lead to become the technical centre of gravity for our go-to-market team. You’ll sit at the intersection of customers, sales, product, engineering and machine learning. You’ll show prospective customers what Cosine can do, help existing customers get deployed, build the technical assets that make our products compelling, and ensure what we learn in the field directly improves what we build. This is not a traditional solutions consultant role. It is highly hands-on. One day you may be running a technical evaluation with an enterprise engineering team; the next you may be debugging a deployment, building a demonstration environment, writing a technical blog or working with ML researchers to turn a new capability into something customers can understand and use. ___________________________________________________________________________ What you’ll do Make Cosine real for customers Lead technical demonstrations and evaluations for prospective enterprise customers. Understand a customer’s development environment, architecture, security model and constraints, then tailor the conversation accordingly. Explain Cosine’s products, models, integrations, deployment options and security considerations with accuracy and confidence. Design and run technical evaluations, pilots and proofs of concept. Work alongside the commercial team to help turn technical interest into customer momentum. Build the technical GTM engine Create high-quality demo environments that show Cosine at its best. Build reusable repositories, workflows and customer scenarios across our coding agent, desktop application and Sparklr model-training platform. Develop technical materials that help the wider GTM team explain, demonstrate and position Cosine effectively. Work with Product, Engineering and ML to turn new capabilities into compelling customer-facing demonstrations. Create technical content such as blogs, product pages, webinars and enablement materials. Get customers successfully deployed Own the technical side of customer onboarding, from initial architecture conversations through to a working deployment. Help customers integrate Cosine with their existing repositories, development environments, infrastructure and enterprise systems. Support deployments across cloud, VPC, on-premise and other controlled environments. Troubleshoot issues directly and coordinate with Engineering when deeper product support is required. Lead onboarding sessions and become a trusted technical counterpart for customer engineering, platform, security and AI teams. Connect customers, GTM and the product organisation Act as the primary technical bridge between GTM and Cosine’s Product, Engineering and ML teams. Bring structured customer feedback into the product organisation, including recurring questions, blockers, feature requests and deployment issues. Identify patterns across customer conversations and distinguish one-off requests from strategically important product gaps. Help the GTM team understand new technical capabilities, product changes and their implications for customers. Help Product and ML understand what enterprise customers actually need in order to adopt Cosine. Raise the technical bar Become the first port of call for technical questions from the commercial team. Build enough depth across Cosine’s products and underlying technology to explain not only what they do, but how and why they work. Help the GTM team communicate technical capabilities accurately and avoid overpromising. Train, document and support the wider commercial organisation. Create a culture where technical rigour and commercial momentum reinforce each other. ___________________________________________________________________________ What we’re looking for You may have come from software engineering, solutions engineering, forward-deployed engineering, developer tooling, technical product or a similar technical customer-facing role. You should be comfortable: Reading, writing and debugging code. Working w
