You will design and optimize pipelines that process 30 billion records per day across customer warehouses collaborate with product and ML engineers to define how LLM-powered customer agents evaluate and act on Fullstory data and make architectural decisions that balance throughput cost and reliability across a product vertical with accelerating revenue and adoption.

To excel in this job you must be comfortable owning large ambiguous technical problems end-to-end from initial design through production health and know how to build data-intensive systems that stay reliable as they scale.

In a typical day you might:

• Maintain extend and scale Go microservices that transform and deliver Fullstory session data into customer warehouses and power the teams MCP server that enables AI agent integrations.

• Develop and maintain dbt models and pipeline orchestration to ensure timely fault-tolerant data migrations across hundreds of customer destinations.

• Define evaluation frameworks for LLM outputs using tools like Langsmith and Vertex AI ensuring AI-powered customer agents produce accurate useful results.

• Investigate and resolve production incidents across the data pipeline implementing systemic fixes that prevent entire classes of failure from recurring.

• Write technical design documents that drive consensus on architectural changes proactively surfacing scaling bottlenecks edge cases and cross-team dependencies.

• Demonstrate sound technical judgment by de-risking work through spikes taking on tech debt deliberately and knowing when to escalate versus dig in.

The impact you will have in 6 Months:

• You will own a critical segment of the warehouse transformation pipeline having shipped improvements that measurably increase throughput reduce latency or improve data quality for customers.

• You will have helped establish initial evaluation criteria and tooling for LLM-generated outputs in the customer agent platform giving the team a repeatable way to measure and improve AI quality.

The impact you will have in 12 Months:

• You are a technical authority on the data pipeline architecture driving end-to-end improvements and mentoring peers on system design and operational excellence.
