For over 20 years, Smartsheet has empowered teams to manage work seamlessly and scale solutions smarter. Now, in our most ambitious chapter yet, we are uniting human teams with AI agents. By orchestrating the work agents do best, automating manual tasks and uncovering insights at scale, we create the space for people to focus on what truly matters: judgment, creativity, and big thinking. That is magic at work, and it’s what we show up for every day. Smartsheet is building the AI connectivity layer that lets enterprise teams work through the AI assistants they already use - Claude, Copilot, Gemini, and ChatGPT. The Model Context Protocol (MCP) is at the centre of that strategy, and this role owns its adoption and growth. With 7,500+ organisations connected across five AI platforms and an Anthropic case study validating Smartsheet's position, MCP is one of the most strategically significant product areas in the company. This is an individual contributor role for a senior product leader who owns product strategy through an adoption lens, and who lives with customers and power users to bridge field signals with engineering direction. The core personas are the people pushing AI hardest - CLI power users, agent builders, and the teams wiring tools and agents into their daily work. You are their voice inside Smartsheet, and Smartsheet's voice to them. This person operates as the product peer to the engineering lead for MCP, planning and launching together day to day. As the platform matures and this role builds the track record to take on more, we expect the scope to grow, potentially into leading industry-vertical specialisation (for example Pharma, Fintech, Construction) as those needs emerge. You will work remotely from the UK and report to the Director, Product Management.
