## Description

At Hex we are using AI to reinvent how business users interact with data, enabling rich data exploration using natural language. Our team of fullstack engineers are responsible for the critical workflows that our customers use to monitor and govern these AI agents, so that users receive answers that are consistently accurate, trustworthy, and grounded in truth. And you'll work across the full stack to shape the core user experience of Hex

Our vision is to be the control center for AI agents within the modern data stack, sitting at the nexus of AI engineering, workflow design, and data modeling to keep up with a fast-moving space., As a software engineer you'll work across the full stack, from complex user-facing interfaces and browser-based IDEs to backend language parsers and SQL generation., * Build observability tools that provide data teams with critical control and visibility, surfacing agent performance, usage metrics, and conversational audit trails for AI-driven insights.

 * Design and implement AI context systems, managing structures for diverse inputs such as free-form rules, certified SQL queries, and deterministic semantic models.
 * Create robust, full-stack workflows that allow data teams to effectively govern, debug, and curate the Hex agent's knowledge, ensuring the reliability and trustworthiness of AI-generated answers across the entire organization.
 * Tackle challenging back-end problems related to SQL compilation, semantic model development, and serializing database context to ensure deterministic and accurate AI outputs.
 * Solve complex front-end UX challenges to present a large volume of technical information in an actionable, clear, and intuitive user interface., Our product is a web-based notebook and app authoring platform. Our frontend is built with Typescript and React, using a combination of Apollo GraphQL and Redux for managing application state and data. On the backend, we also use Typescript to power an Express/Apollo GraphQL server that interacts with Postgres, Redis, and Kubernetes to manage our database and Python kernels. Our backend is tightly integrated with our infrastructure and CI/CD, where we use a combination of Terraform, Helm, and AWS to deploy and maintain our stack.
