Description

Build and maintain agentic systems that continuously collect, process, and surface signals from social platforms, on-chain data, and ads ecosystems.

Build multi-step AI agents for research, synthesis, monitoring, and reporting with memory, tools, and structured output schemas.
Build full-stack applications and dashboards that make intelligence accessible across client accounts.
Work closely with internal teams across marketing, PR, content, growth, and social to understand workflows before building solutions.
Identify signal gaps and design systems that solve problems for multiple teams from a single architecture.
Evaluate and use the right AI tooling, including deciding when no-code tools are sufficient versus when custom development is needed.

Experience with Dune Analytics or equivalent SQL querying against on-chain data is a strong plus.
Familiarity with wallet activity, token flows, and on-chain behavioral signals is a strong plus.
