## About the role

We are looking for engineers who enjoy building and shipping quickly, learning how other teams work, and seeing their work change how an entire company operates. As a Senior Software Engineer on the Data & AI team, you'll expand Lighthouse, our internal data and AI platform, into the layer that lets every function at Lightspark run on trusted data and AI agents.

## What they're looking for

- 4+ years experience shipping and maintaining production systems, data engineering, ML engineering, and backend/full-stack backgrounds all fit
- You've built an internal platform or workflow system that other teams adopted, not just features on top of one
- You've built with LLM APIs, agent frameworks, and MCP in production, beyond prompting, and you know what belongs in code versus a model
- Strong fundamentals in TypeScript/Node or Python and the willingness to work in both, plus fluency with a cloud data warehouse such as BigQuery, Snowflake, or Databricks
- You can sit with a non-technical team, understand how their work actually happens, and come back with a system
- Comfortable working with ambiguity in a startup environment
