Full Job Description
We're hiring a full-time Software Engineer, AI Platform to own the data platform, ETL pipelines, and agent infrastructure that everything else at the company runs on. This is the platform layer that makes Fluency's AI work reliable, observable, and usable in production. It moves data through LLMs, transforms agent outputs into structured downstream data, runs jobs reliably, and keeps the system fast, cheap, and observable as we scale. Because we're an early-stage company moving fast, we're looking for an engineer who can build the platform, keep it running, and make tradeoffs while priorities shift. This is an in-person role, 5 days a week in our office. The ability to balance reliability with iteration speed is essential.
