Developer Relations Engineer at Cresta · LumiJobs

Responsibilities

Cresta is looking for a Senior Developer Relations Engineer to become the technical voice of our AI agent platform in the developer and partner community. This is a hands-on, hybrid role: part software engineer, part storyteller, part community builder. You'll show developers, partners, and prospective customers how to build, test, and ship real AI agents on Cresta, primarily through video, blog posts, tutorials, and workshops, and you'll bring what you learn from that community back into the product.
Cresta's platform is enterprise-heavy (large regulated customers, complex integrations, rigorous testing and evaluation requirements), so this role needs someone who can go deep technically, not just narrate a demo. We also maintain some open-source tooling and sample projects, so comfort working in the open is a plus.
Create technical content that teaches developers how to build AI agents on Cresta: blog posts, written tutorials, and long- and short-form video (walkthroughs, live coding, demo breakdowns).
Build and maintain sample apps, code snippets, and reference integrations that show best practices for building, testing, and evaluating agents on the platform, including in open-source repos where appropriate.
Plan and run workshops for developers and partners, both virtual and in-person, that take people from zero to a working agent.
Represent Cresta at conferences, meetups, and partner events, delivering talks and demos and engaging directly with attendees.
Run a feedback loop with developers and partners: collect what's confusing, missing, or broken in the platform and developer experience, and route it to Product and Engineering with clear, actionable detail.
Partner cross-functionally with Product, Engineering, and Marketing to keep messaging and documentation aligned with what the platform can actually do.
Improve onboarding and the first-build experience for new developers and partners evaluating the platform, including getting-started guides and sandboxes.
Stay hands-on with agent building and testing: prompt engineering, tool/function calling, RAG, and evaluation, so the content you produce reflects real, current platform capability rather than marketing copy.
