# Senior AI Platform Engineer

You'll turn AI-built prototypes into secure production systems that run on enterprise data. That means hardening Node, React, and Postgres applications, connecting them to Databricks and Snowflake, and running open-weight LLMs on dedicated GPUs. Sensitive data gets processed at scale without leaving a controlled environment or touching a public model API. This is a hands-on senior role with real ownership. You'll set the technical standards for how our applications reach production, working directly with the Senior Leadership Team and the data teams you integrate with. What you'll do Take apps built quickly with AI coding tools (Cursor, Claude Code, Lovable, and similar) and make them production-ready: architecture, authentication, testing, observability, and CI/CD. Connect Node, React, and Postgres applications securely to Databricks and Snowflake, working within their governance and access controls. Design APIs and pipelines that move data between Postgres and Databricks or Snowflake, reliably and with a full audit trail. Deploy and operate open-weight LLMs on dedicated GPU servers using vLLM or a similar inference engine. Build batch and real-time pipelines that run LLM extracti
