Greylock Partners
San Jose, CA Full Time
POSTED ON 1/8/2026
AVAILABLE BEFORE 5/30/2026

Early-stage, cybersecurity investment (valued over $100M at Seed), founded by a successful serial entrepreneur, is looking to hire a Founding Data Engineer. Bonus points for prior industry exp in cybersecurity.


Our ideal candidate will be a seasoned data engineering specialist (with 5 years relevant industry exp) who can help this company create its next generation of analytics infrastructure.

Qualifications:

  • Demonstrated expertise in building and managing very large data platforms (multi-petabyte range)
  • Background in both streaming and batch data processing
  • Hands-on familiarity with open-source technologies commonly used in lakehouse setups (e.g., Iceberg, PostgreSQL, Parquet, graph databases such as Neo4j)
  • Strong experience with streaming and analytics frameworks like Kafka, Spark, or Flink
  • Solid understanding of data transformation practices
  • Advanced proficiency in Python
  • Clear communication skills and the ability to produce strong technical documentation
