They've recently closed a multi-million-dollar round backed by leading technology and gaming investors, and are now building out the team that turns model progress into a product people actually want to use.This is a founding hire working directly with the founder and founding engineering team to build the agent systems that bridge the gap between a spec and something shipped.The roleDesign, build and operate the pipeline that takes a product from spec to shipped build: planning, generation, review and releaseBuild evaluation and regression tooling that catches quality issues before they shipBuild the routing layer that picks the right model for each step on quality, latency and costOwn retrieval and context systems, with a path into fine-tuning models on the data the platform generatesHave real scope to shape how AI is used across the whole product, not bolted onto one featureThey're looking forSomeone who follows the field closely and is already testing new models and techniques as they landProduction experience with LLM systems: multi-step pipelines, tool-using agents, or eval infrastructureA strong systems engineering background (TypeScript preferred, but deep experience elsewhere is fine)Experience designing and running evals: test sets, benchmarks, regression trackingA track record of managing inference cost alongside quality and latency in something liveComfortable in an early-stage, in-person, high-ownership environment
