Your impactWe're looking for an AI-native Senior Content Marketing Manager to build Inworld's voice in public. Realtime AI is a category where developers and founders form their shortlist long before they ever talk to us. Your job is to make sure we're in that conversation, consistently and in a voice worth following.
This role covers executive thought leadership, our social channels, employer brand, and the production system behind all of these. You'll work closely with the VP of Marketing and PMM. It's a hands-on role: you'll write the post, cut the clip, and hit publish yourself.
Build the executive voice
Ghostwrite for our founders and technical leaders across LinkedIn, X, and long form - posts, essays, and POV pieces that read like them rather than like marketing
Sit in on research and engineering conversations and pull out the ideas worth publishing
Develop the editorial point of view that makes our content worth following rather than worth skimming
Own our social channels
Run LinkedIn, X, and YouTube as owned channels with their own audience
Show up where developers actually discuss realtime voice - Reddit, Discord, Hacker News, and technical communities
Repurpose launches, benchmarks, press coverage, and demos into content we can use everywhere
Metrics that matter - follower quality, engagement from the right accounts, and traffic that converts
Build an AI-native content engine
Use AI tooling to multiply output without flattening voice - drafting, research, repurposing, and format conversion
Break every substantial piece into the clips, threads, and posts
Build the systems and templates that let content ship on cadence
Hold the standard against AI slop
4-7 years in content marketing, ideally to a developer or technical audience
Exceptional writer with range - you can write as a founder, as an engineer, and as the brand, and they sound different
Demonstrated track record growing a social presence on LinkedIn and X, with the numbers to show for it
Fluent with AI tooling as a production system
Comfortable interviewing researchers and engineers and turning it into something readable
Judgment about what not to publish
Power user of Claude Code or equivalent, thinking in terms of agents and systems
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).The US base salary range for this full-time position is $150,000 - $210,000.

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.
