About the role

Senior Software Engineer on the Data & AI team to expand Lighthouse, Lightspark's internal data and AI platform, enabling all company functions to run on trusted data and AI agents.

Responsibilities

  • Building and owning our internal AI platform: the agent harness, MCP servers and tool integrations, context and access services, sandboxed execution, and cost and usage tracking
  • Embedding with Finance, Sales Ops, Compliance, and onboarding to understand how their work actually happens, then shipping the systems that replace the manual version and handing them off to those teams
  • Extending our data infrastructure alongside our Staff Data Engineer: DBT models, BigQuery, orchestration, and the production pipelines
  • Sharing ownership of monitoring, alerting, and data reliability for the systems that unblock product launches
  • Partnering with Engineering to optimize their own dev systems and tooling

Qualifications

  • 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
  • Experience in payments, crypto, or blockchain is a plus, but not required
  • Based in LA or Openness to relocate to Los Angeles, California
