Product Marketing Manager

MUI is a fast-growing startup focused on building a world-class ecosystem of React UI libraries and tools. They are seeking a Senior Product Marketing Manager to establish MUI X's positioning in the Enterprise market, build the marketing foundation, and generate a qualified pipeline for growth.

Responsibilities:

• Establish MUI X's positioning and messaging in the Enterprise market - and ensure Sales can articulate them in every deal
• Generate a qualified pipeline that accelerates Enterprise growth
• Build the marketing foundation - processes, playbooks, and infrastructure - that will scale with the business
• Own and evolve MUI X's positioning and messaging, with a primary focus on the Enterprise market
• Develop differentiated narratives that directly address the core buying conversation: MUI X vs. AG Grid, Bryntum, and the ever-present "we'll build it in-house" alternative
• Craft messaging for multiple buyer personas - the frontend engineers who evaluate, the tech leads who recommend, and the engineering managers, VPs, and CTOs who approve budgets
• Translate product capabilities (Data Grid, Charts, Date & Time Pickers, Tree View) into clear value narratives tied to productivity, time-to-market, and total cost of ownership
• Ensure consistent positioning across the website, sales materials, campaigns, and product launch communications
• Build MUI's sales enablement foundation from scratch: battle cards, competitive positioning docs, objection-handling guides, pitch decks, ROI frameworks, and case study templates
• Work closely with AEs to understand where deals are won and lost - and create materials that directly address those moments
• Define ICP and buyer journey maps that give Sales a sharper lens on who to prioritize and how to engage them at each stage
• Translate product releases and roadmap highlights into sales-ready narratives that AEs can use in active deals
• Lead GTM planning for major MUI X releases and commercial initiatives - define the plan, align stakeholders across Sales, Product, and DevEx, and drive execution end to end
• Create launch-ready assets: website copy, release communications, announcement emails, and supporting sales materials
• Work with Product to ensure launches are framed for commercial impact, not just developer awareness
• Build and maintain a competitive intelligence function: track AG Grid, Bryntum, and other alternatives; understand how they position, price, and win deals
• Synthesize customer and market insights into actionable recommendations for messaging priorities, roadmap input, and GTM decisions
• Establish a regular cadence for feeding competitive and customer intelligence back to Sales and Product
• Design and execute campaigns that generate a qualified pipeline for the Sales team, with a focus on Enterprise buyers
• Partner with Sales and Ops to define lead qualification criteria and establish tight feedback loops between marketing activity and sales outcomes
• Own and track key funnel metrics: marketing-sourced pipeline, conversion rates, cost per qualified opportunity, and return on marketing investment
• Lead performance campaigns across relevant channels (Google, LinkedIn, developer communities); run experiments and optimize based on data

Requirements:

• 4-6 years of experience in product marketing or growth marketing, with meaningful time spent in B2B SaaS
• Demonstrated experience building marketing programs from scratch - not just inheriting and optimizing existing infrastructure
• Experience marketing technical products to engineering audiences: developers, tech leads, engineering managers, and technical executives
• Strong ability to develop positioning and messaging independently - you can write a sharp, differentiated positioning document without waiting for a brief
• Proven track record of generating qualified pipeline for Sales teams, with clear examples of measurable impact
• A 'manager of one' mentality: you define your own priorities, build your own plans, and execute without needing constant direction or oversight
• Excellent written communication skills in English - at a level that earns the trust of a developer audience
• Comfortable operating in a fully remote, async-first environment with minimal process and high ownership
• Experience at a developer tools company, open-source business, or infrastructure software company
• Familiarity with product-led growth (PLG) models - particularly the challenge of converting free or community users into commercial customers
• Hands-on familiarity with frontend development or React. You don't need to be an engineer, but you need to understand the audience you're speaking to
• Experience as the first or only PMM at a company
• Familiarity with marketing automation and CRM tools (e.g., HubSpot)
