We’re hiring a Senior Technical Product Marketing Manager to lead positioning, messaging, and product adoption across our AI and agentic context solutions. This is a high-impact role for a technical marketer who thinks and acts like a builder. Most AI systems don't fail because the model is bad—they fail because they lack a crucial, contextual foundation. MongoDB owns a piece of nearly every step in that chain. This role requires deep technical expertise across the context stack—including VoyageAI embedding and reranking models, MCP Server, and the coding agent ecosystem (Claude Code, Cursor, GitHub Copilot, Gemini CLI, Codex, etc.)—combined with product marketing instincts to deeply understand the market and translate technical depth into crisp, differentiated messaging for distinct user and buyer personas. The ideal candidate has experience building and shipping AI-enabled products and using developer tools in their day-to-day workflows. Individuals with prior experience in technical sales, developer relations, or software development are encouraged to apply. The ideal candidate is a voracious consumer of AI research and pays close attention to shifting patterns in how software and AI applications are built and consumed. This individual is confident in communicating with technical practitioners and non-technical decision makers in one-to-few and one-to-many engagements for internal and external audiences. You will leverage your technical depth to craft clear, compelling, and highly differentiated messaging by working backward from customer requirements. We are looking to speak to candidates who are based in Dublin for our hybrid working model. What You’ll Do Drive Strategy & Execution: Act as the strategic owner for MongoDB’s context engineering portfolio—MCP Server, Agent Skills, VoyageAI, and more— aligning roadmap and go-to-market with MongoDB’s long-term business goals, in collaboration with Product Management, Engineering, Developer Relations, Partn

The Team + The Role The Product Design team at Pendo works closely with senior product leaders and sits at the center of product strategy and delivery. The team operates close to both the problem and the build, using LLM-assisted exploration, code-level prototyping, and customer validation before work moves into Figma for systems and polish. Designers ship across a multi-app platform with a high bar for craft, reliability, and product impact. As a Staff Product Designer, you will lead design across the platform and move toward the highest-impact work. You will own projects end-to-end, from problem framing through shipping, partnering with product and engineering to make sophisticated experiences feel simple. AI-assisted workflows are part of how this team works every day, and this role is expected to use, improve, and share those workflows. This role is based in our Raleigh office. What this looks like day-to-day Platform design leadership: Lead design across multiple product areas and own projects from problem framing through shipping. Partner with product and engineering to reduce complexity without losing capability, starting from customer need rather than feature requests. Prototyping and validation: Build interactive prototypes using code-adjacent tools and validate them with real users before engineering investment. Use findings to sharpen flows, surface edge cases, and improve the work before full systemization. AI-integrated workflow: Use AI tools actively across the design process, including LLMs for problem framing and brief development, Cursor and Claude for prototyping, and generative tools for faster interface exploration. Document and share prompts, patterns, and workflows with design and engineering partners. Design systems: Translate and evolve Pendo's design principles into reusable components and patterns. Identify when to extend existing systems and when to push them forward, then drive those decisions with stakeholders. Cross-functional alignment
