What this job asks for AI summary

A founding data hire at an early-stage AI security startup, responsible for building the entire analytical data foundation from scratch — pipelines, semantic layers, canonical metrics, and AI evaluation systems. The role spans analytics engineering, product and business intelligence, and LLM/agent performance measurement, with an expectation to eventually hire and lead a data team. Best suited to a senior generalist who thrives in ambiguous, high-ownership startup environments.

Why we read it this way (7)

The role title is 'Founding Applied Data Scientist' but the day-to-day work spans analytics engineering (pipelines, semantic layers, dbt-style modeling), product/business BI, and AI/LLM evaluation — making it a genuine hybrid. 15-2051 Data Scientists was chosen as primary because of the explicit AI evals, model performance measurement, and applied data science framing; 15-1243 Database Architects is the runner-up given the heavy emphasis on building the analytical data infrastructure and semantic layer.

No compensation range is stated in the posting.

The role is listed as in-person 5 days a week at a Brooklyn, NY office — remote is not offered.

The 'Nice to have' section lists specific tooling (Hex, Langfuse/Braintrust/Arize/Phoenix, ClickHouse/BigQuery/Snowflake/Databricks/DuckDB, dbt, Python/TypeScript) that does not appear in the hard requirements block; all are marked preferred accordingly.

Langfuse, Braintrust, Arize, and Phoenix are listed together as interchangeable AI observability/eval tools; they are captured as a single skill with alternatives.

ClickHouse, BigQuery, Snowflake, Databricks, and DuckDB are listed together as interchangeable analytical data systems; ClickHouse is used as the primary name with the others as alternatives.

The requirements section references 'modern AI eval frameworks, model performance measurement, LLM observability, or similar systems' without naming a specific tool — this is captured as the 'LLMs' skill (hard gate on the capability) with specific tooling appearing only in the Nice to have section.
