About the role

Kikoff exists to help millions of people build credit. That only works if they trust us with their financial data. This role owns the Data Security pillar at Kikoff: how data is classified, accessed, encrypted, moved, and audited across our entire stack. You will own and dictate the data security roadmap. You define the strategy, sequence the work, and drive it to done. Your work will be felt by every engineer at Kikoff and every customer we serve, and it will shape how we handle sensitive data as we scale.

What they're looking for

  • 6+ years in security engineering with deep, hands-on data security experience: encryption, tokenization, access control design, key management
  • Strong command of AWS security primitives (IAM, KMS, S3 security, VPC controls)
  • Experience securing a modern data stack: Snowflake or a comparable warehouse, plus relational databases in production
  • You've designed and shipped access control systems, not just configured them. Row/column-level security, ABAC/RBAC, access brokering
  • Fluency in at least one language for automation (Python, Go, Ruby, or similar)
  • Comfortable in a regulated environment
