About the Role:

LMArena is looking for a Developer Relations Lead to grow, empower, and support the technical community shaping the future of AI evaluation. In this role, you will be the bridge between developers and the LMArena platform, representing their needs internally while driving adoption, integration, and meaningful participation externally.

This is a high-impact position at the intersection of research, infrastructure, and community. You’ll help researchers, AI developers, and technical contributors engage with our APIs, data, and tools, while also telling the story of how LMArena works under the hood.

We believe in evaluation infrastructure that is open, community-driven, and grounded in real-world usage. This role is for someone who can advocate for our mission, teach through code and content, and inspire others to contribute to better AI progress.

Responsibilities:

• Driving developer adoption by making it easier for researchers and engineers to use our evaluation tools, APIs, and datasets.

• Creating technical content such as tutorials, demo apps, notebooks, deep dives, and walkthroughs that explain LMArena’s infrastructure and methodologies.

• Building bridges with the AI community through direct support, workshops, conferences, hackathons, and Discord.

• Collecting and surfacing developer feedback to inform product, API, and tooling improvements.

• Partnering with model providers and contributors to help them integrate into the platform and make the most of evaluation.

• Championing community-built tools, libraries, and insights, helping amplify external contributions and shape standards for transparent evaluation.

• Collaborating cross-functionally with Product, Engineering, Comms, and Research to help define how we explain and scale the platform.
