Principal Software Engineer

AI summary of the role

Principal Software Engineer on the AI-SOC team at Rapid7, building the autonomous investigation platform that powers MDR.

What you’ll do

  • Architect and implement core platform components across the AI-SOC stack, including data ingestion pipelines, query engines, investigation orchestration, and ML model integration layers.
  • Own technical direction for the team's most complex and ambiguous problems, defining interfaces, data contracts, and system boundaries.
  • Partner with ML/AI engineers to design infrastructure for training, serving, and evaluating disposition models.
  • Establish engineering standards for system design, data modeling, testing, and observability; lead design reviews and mentor senior/staff engineers.

What you’ll bring

  • 10+ years of software engineering experience with a track record of leading complex, high-scale system design in distributed environments.
  • Deep expertise in data systems: stream processing (Kafka, Flink), distributed query engines, data modeling, storage (DynamoDB, S3, data mesh).
  • Strong working knowledge of ML/AI system design: model serving, feature pipelines, embeddings, or LLM integration.
  • Experience in cloud-native environments (AWS preferred) with infrastructure patterns for AI/ML workloads.
