About the role
We're hiring our founding Platform Engineer, Security to design, build, and operate the security infrastructure that powers Decagon's AI platform. This is a builder's role: you'll spend your time creating durable, well-engineered systems including paved paths for secure service creation, security tooling that automatically applies secure configurations, and infrastructure-as-code that makes it easy for every engineer at Decagon to do the right thing.
What they're looking for
- A track record of being an early or founding platform/infrastructure/security engineer at another company
- Experience building internal platforms: service templates, paved-road deployment, self-serve environments, or developer portals
- A security-minded approach to the software supply chain (provenance, secrets, least privilege) and familiarity with static analysis tooling (Semgrep, CodeQL)
- Experience with detection and response data pipelines (Kafka/Pulsar, Splunk/Panther/RunReveal, or similar)
- Knowledge of enterprise compliance requirements (SOC 2, ISO 27001, GDPR) from an infrastructure and platform perspective
