Developer Marketing Engineer

E2B is a fast-growing Series A startup with over $37M in funding and 8-figure revenue. We are building the Agent Cloud and power the infrastructure behind AI labs and some of the most widely used consumer and enterprise agents, including Manus, Genspark, Lindy, ClickUp, Groq, and Black Forest Labs. Our team includes original authors of Firecracker, the AWS microVM technology powering Lambda, along with alumni of Cognition, JetBrains, Zapier, and Wish.

E2B's product moves faster than its content does. Developers discover E2B through code, demos, and posts that show a sandbox running inside the tools & frameworks they already use - Codex, Claude Code, LangChain, the Vercel AI SDK, OpenAI Agents SDK, and beyond. We’re looking for someone who showcases the full range of ways developers can use E2B with the top tools in the ecosystem — shipping end-to-end demos (code, article, & video) for each integration, communicating the latest product updates, and empowering the community to build cool things on top of E2B.

• E2B's social presence across X, LinkedIn, and YouTube — plus the social calendar and key communities like Hacker News.

• Demo content production: short videos and companion posts/repos and cookbook recipes showing E2B running inside named ecosystem tools. Concretely, demos of E2B with LangChain, LlamaIndex, Vercel AI SDK, OpenAI Agents SDK, CrewAI, Anthropic Claude Code, Codex CLI, and LLM providers including OpenAI, Anthropic, Mistral, Groq, and Together AI.

• Standalone projects in the pattern of E2B's existing open-source projects (Fragments, AI Data Analyst, Surf) that can unlock further growth.

• Working with the GTM team on joint opportunities. Co-marketing with partners and customers: joint demos, launch content, integration announcements, and the technical proof points sales needs in front of prospects. You are the person who turns a partnership into something a developer can actually run.

• Reading the numbers and acting on them. You know which demos and posts drive signups, GitHub stars, and SDK usage; you can pull and analyze that data yourself, and you use it to pick what to build next instead of guessing.

Must-haves:

• Prior work with AI agent frameworks or LLM tooling.

• A public body of work you made: shipped developer videos, successful X threads, or creative demos with real engagement.

• Write good code that showcases E2B in the best possible way.

• Can produce a watchable short video end to end: script, screen capture, edit, publish. You may involve contractors for parts of the production process, but you own the delivery.

• Writes in a voice that reads as native to developers.

• More than 4 years of relevant experience. This can be prior DevRel, developer marketing, a strong personal content channel, or engineering plus a side habit of building in public.

Nice-to-haves:

• An existing developer following on X or YouTube.

• Open-source contributions.

• Being engaged with the AI dev communities & the tools they use.

• Comfortable speaking and presenting E2B at our own events and at partner events and conferences, including building the demos you present. Hackathons, meetups, and joint launch events with partners.

Location: In person in San Francisco. E2B does not hire remotely for this role.
