Senior Software Development Engineer
About the Role
Own FortiCNAPP's composite alerts pipeline — a Python/Spark system that turns thousands of raw security detections into high-confidence intrusion narratives with entity graphs and timelines. You'll be the sole long-term owner of a mature, 5-year-old system, inheriting it from a departed founding engineer with structured onboarding support.
Responsibilities
- Own the aggregation engine and the alert/entity/evidence schema shared across teams
- Complete the migration from a cloud data warehouse to an open-table-format lakehouse
- Reduce infrastructure cost (Spark efficiency, warehouse sizing, scheduling)
- Fix alert-quality issues: incomplete graphs, duplicate alerts, mismatched threat tags
- Manage production operations on Kubernetes: deployment, rollout, on-call
Requirements
- 6+ years building production data/backend systems in Python
- Production-grade Apache Spark experience (debugging OOMs, skew, partitioning)
- Strong SQL and warehouse/lakehouse experience with cost awareness
- Experience owning a cross-team data schema (Protobuf, Avro, Thrift, etc.)
- Kubernetes operations experience (scheduled jobs, rollouts, config management)
- Track record safely retiring legacy systems (parity testing, kill switches)
- Genuine interest in security detection logic
- Comfortable inheriting an under-documented system solo
- Must be authorized to work in the U.S. without sponsorship
Preferred Qualifications
- Graph databases (Neo4j/Cypher)
- Open table formats (Iceberg/Delta/Hudi)
- Cloud security/detection background (AWS/GCP/Azure audit logs, K8s audit events, MITRE ATT&CK)
- Go
- Prior experience as a sole service owner
