About the Role
We are 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 focused on creating durable, well-engineered systems including paved paths for secure service creation, security tooling that automatically applies secure configurations, and infrastructure-as-code. As the first dedicated engineer in this area, you will have a significant impact on how security infrastructure is built and shape the technical direction of the infrastructure security program. This role is close to the business, directly enabling high-value deals with security-conscious enterprises and offering a clear path for growth in security, infrastructure, and platform engineering.
Responsibilities
- Design and implement secure, multi-tenant infrastructure that isolates customer data while enabling efficient AI model serving across our platform
- Build "golden paths" for security including service templates, libraries, terraform policies, and automation, so new services are secure and production-ready by default
- Own infrastructure-as-code (Terraform) and GitOps best practices, including reusable modules and policy-as-code
- Expand and help operate the platforms behind alerting detection, secrets management, IAM, and automated remediation, integrating them cleanly into CI/CD and developer workflows
- Partner with Security, Infrastructure, and product engineering teams to translate enterprise and compliance requirements (SOC 2, ISO 27001, GDPR) into reliable, automated technical controls
- Participate in security on-call and continuously raise the bar on operability, runbooks, and incident learnings
Requirements
- 8+ years building and operating production infrastructure, with meaningful exposure to security or a strong interest in moving deeper into security problems
- Deep knowledge of Google Cloud Platform and/or AWS, including compute, networking, IAM, and security services
- Proficiency with infrastructure-as-code (Terraform, Ansible, or similar) and a track record of building developer-facing tooling and automation
- Strong coding ability in at least one systems language (eg. Python, Go, TypeScript) and comfort building paved-path tooling teams actually adopt
- Experience applying AI-assisted tooling (Cursor, Claude Code, and similar) to make engineers dramatically more effective
- Experience with secure container deployment, service mesh, and Kubernetes security best practices
- Observability and incident-response tooling experience (instrumentation, alerting, dashboards), with a bias toward eliminating toil
- Clear written communication and the ability to turn ambiguous requirements into simple, reliable designs
- 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
