Your impactWe're looking for a Founding Growth Lead who is equally hands-on in driving the market expansion and accelerating adoption across the developer ecosystem. This is a critical, cross-functional role that will own the entire growth funnel, from developer awareness and acquisition to engagement and retention. You will be the architect of a technical growth engine, integrating product, engineering, and marketing to drive sustained developer adoption, accelerate activation and retention, and translate product adoption into revenue growth.
What you’ll doDefine and build the growth function from the ground up, establishing the technical infrastructure, frameworks, and repeatable processes that will scale
Develop and execute strategies to create, engage, and grow our audience across marketing channels (Google, Linkedin, Meta, Reddit, X, etc.) and all possible developer touchpoints
Partner with product and engineering leadership to influence roadmap prioritization, pricing, and packaging strategy using growth data, funnel analysis, and user insights to inform monetization decisions and conversion optimization
Build a thriving developer ecosystem, fostering community engagement and advocacy
Coordinate high-impact product launches that generate significant visibility, leveraging newsletters, podcasts, press, publications and other outlets

Build and maintain marketing infrastructure, tracking, dashboards, attribution tooling
Own technical content, from blog posts and landing pages to demo script and onboarding flows
Former founder or seasoned growth leader with experience scaling early-stage, high-growth companies
Strong product or engineering background with technical fluency, able to design and implement technically driven growth systems
Deep analytical skills: comfortable with growth modeling, cohort analysis, A/B experimentation, funnel diagnostics, and data-driven decision-making
Track record of running product launches and campaigns that directly accelerated adoption and revenue
Hands on experience managing performance marketing budgets, paid channel strategy, and attribution across the full funnel
Thrive in ambiguity and see constant change as opportunity, not obstacle
Naturally spend nights and weekends hands-on with the latest technical innovations
Bring ideas and solutions, not org charts and territory-building
Consider marketing as a product surface that can be engineered and automated
Prior exposure to a product-led growth strategy and usage-based business model
BA/BS degree or higher, with technical degrees a plus
Candidates must be based in the SF Bay Area or willing to relocate (you will be working on-site in our South Bay office a few days a week).

What We Do
Inworld AI is a realtime voice AI research lab and platform. It builds the voice layer for consumer AI, the speech that powers companions, tutors, coaches, customer-service agents, and creative and content applications. Inworld's flagship product is text-to-speech, top-ranked on the independent Artificial Analysis Speech Arena, and around it the company offers a full realtime voice stack. That stack includes text-to-speech (Realtime TTS-2, with over 100 languages and natural-language voice steering), speech-to-text, and an LLM router that reaches 200+ models from every major provider with no markup. Developers can call any product on its own, for example Realtime TTS through a single API call, or combine speech-to-text, an LLM, and text-to-speech into one live conversation through the Realtime API. Dedicated GPUs are available for the largest workloads. Inworld serves developers and founders building consumer AI products. As voice quality becomes commoditized, the company's focus is realtime conversation at scale: voice agents that respond in roughly 200 milliseconds for thousands of simultaneous users, at a cost that stays efficient as usage grows. Inworld is a product-oriented research lab. Its founding team pioneered conversational AI and generative models at API.AI (acquired by Google and renamed Dialogflow), Google, and DeepMind, with expertise spanning language models, speech synthesis, multimodal interaction, and design. Inworld has raised more than $125M from investors including Lightspeed, Kleiner Perkins, Founders Fund, CRV, Intel Capital, BITKRAFT Ventures, Section 32, Meta, Microsoft's M12, and LG Technology Ventures. The company was one of six selected for the 2022 Disney Accelerator.
