Developer Advocate

• Build with Tessl: Go beyond writing about the product, build with it. Create apps, integrations, and creative projects using Tessl that inspire and enable the developer community to do the same.
• Content Creation: Write articles, tutorials, and guides, and produce videos that give developers practical, actionable insights into AI native development with Tessl.
• Community and Events: Be an active, visible presence in the AI developer community, speaking at events, participating in forums, engaging on social, and helping highlight what developers are building with Tessl.
• Ecosystem Exploration: Constantly explore the AI developer tooling landscape, identifying integration opportunities and ways to connect Tessl with the broader ecosystem.
• Show Up Where Developers Are: Run webinars, appear on podcasts, and make yourself at home in other people's communities. That means Discord servers, Slack groups, subreddits, newsletters, and anywhere else developers are gathering., * Active at events: You speak at meetups or conferences, engage in developer communities, and have a point of view worth hearing., * A technical interview and role deep dive with Head of Developer Relations, Simon Maple
• A take home technical and content creation test, exploring an AI software.
• An on-site session with a Tessl leader.

Do you have experience in Technical writing?, * A builder's mindset: You get excited about making things. Whether that's a slick integration, a creative app, or an experiment that no one's tried yet, you'd rather ship something than just describe it.

• Strong communicator: You can write clearly and engagingly about technical AI topics.
• Development skills: You're comfortable enough with code to build and hack on things yourself. You don't need to be a full-time engineer, but you ship.
