Principal Software Engineer

The Data Platform team is responsible for ingesting security telemetry data from our customers’ environments, transforming the data, and making it available to AI agents that continuously scan this data to look for malicious activities. We also tackle hard problems such as correlating entities across events from disparate sources and generating a queryable baseline view of activities that will allow agents to detect anomalies.

As a Principal Software Engineer on this team, you will lead cross-functional projects and drive architectural changes to meet strict latency and reliability requirements. You’ll co-own the data ingestion, transformation, and search layers that power agentic threat hunting workflows. We currently ingest terabytes of data per day and are growing fast. This role is ideal for engineers who have built large distributed systems from the ground up and scaled it to process billions of events/requests per day.

Expected Impact

• Design, build, and maintain scalable data pipelines that ingest and process large volumes of security telemetry (TBs / day)
• Own API and event stream integrations across a wide range of third-party data sources (EDR, IAM, Cloud, SaaS)
• Partner with product stakeholders to build data solutions that will be consumed by both internal and external customers
• Guide the future technical direction that allows rapid development of product capabilities and efficient scaling of backend systems
• Use AI agents to build creative solutions to solve problems such as data mapping and entity correlation
• Set and promote engineering standards and best practices, including observability, monitoring and automated testing
• Be a mentor to junior engineers and help grow the engineering talent within the team

• 8+ years of experience building large-scale distributed systems supporting customer-facing products
• Proficiency in Python, Java, Go, Rust, or similar
• Hands-on experience designing large-scale event streaming systems such as Kafka or similar
• Experience working on search or analytics products over large datasets
• Strong systems thinking and understanding of performance, cost and complexity trade-offs
• Experience with either AWS or GCP
• Ability to adapt, iterate, and ship quickly
• Hunger for growth and the desire to work in a low-ego environment
