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)
