About The Position

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people. The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms. About This Team and Role: The New Products organization at Mozilla operates as an internal incubator for high-potential ventures. You will be joining Tabstack, which is operating as a fast-paced autonomous team within the organization. Tabstack is building the essential browser automation stack for AI agents. Our goal is to make it as simple as possible for developers to integrate fast and reliable web interactions into their AI-powered systems and agentic applications. We are seeking a Founding GTM Lead to own early customer growth and shape Tabstack’s go-to-market strategy. You will be responsible for growing the platform and discovering and validating repeatable paths to customer acquisition. This is a 0→1 role where success is defined by learning velocity, customer signal, and commercial traction. The ideal candidate has the heart of a developer but the mindset of a founder. You are comfortable in a "0 to 1" environment with minimal support, eager to experiment, and willing to get your hands dirty in everything from writing integration docs to negotiating contracts.

Requirements

5+ years of relevant experience: A mix of Product Marketing, Technical Sales, Founder experience, or Developer Relations with a heavy focus on revenue/growth.
Technical Fluency: You must be able to speak the language of AI engineers. You don’t need to be a core contributor, but you should understand the mechanics of browser automation, APIs, and the current LLM landscape.
The "Hustle" of a Founder: Experience working in early-stage startups or new product incubators. You know how to generate leads without a massive marketing budget.
Strong Communication Skills: Proven ability to produce clear, accessible technical writing (docs, blogs) and persuasive business communications (decks, outreach emails).
Deep Industry Knowledge: Understanding of the modern AI stack (LangChain, LlamaIndex, vector DBs) and the browser automation space (Puppeteer, Playwright, Selenium).
Commitment to our values: Welcoming differences Being relationship-minded Practicing responsible participation Having grit

Nice To Haves

Experience as a technical founder or early employee at a DevTools company.

Existing relationships with key startups and enterprise tech teams in the AI ecosystem.
Familiarity with open source business models and the "tech for good" ecosystem.

Responsibilities

Drive Customer Acquisition & GTM Experiments
Design and run early go-to-market experiments to discover repeatable ways to reach high-intent audiences. This includes scrappy, high-signal tactics such as targeted outreach, ecosystem engagement, founder-led sales, and experimentation with messaging and channels while prioritizing learning and signal over scale.
Own Messaging, Positioning & Meaningful Technical Content
Craft the core narrative and value proposition. You will lead the content marketing strategy, experimenting with different messages across blogs, landing pages, and use cases to see what drives adoption. You will identify the most compelling stories and collaborate with the engineering team to ensure technical accuracy, while you focus on optimizing the funnel and communicating the "why" behind Tabstack to drive conversion.
Establish Commercial Validation & Sales: You will help secure our first wins. Whether this is closing paid contracts or securing committed design partners, you are responsible for proving the commercial viability of the product.
Generate Product Feedback Loops: You are the frontline researcher. You will translate customer objections and friction points into structured feedback for the engineering and design teams to prioritize the roadmap.
