TL;DR · Senior Security Platform Engineer

The Senior Security Platform Engineer joins the security team to operate at the intersection of cloud infrastructure, platform engineering, and security operations. This role serves as a primary technical escalation point for platform reliability and security incidents across multi-account cloud environments. You will own infrastructure-as-code using Terraform, manage IAM secrets, and administer networking components like WAFs, DNS, and CDNs. Responsibilities include operating the Elastic Security SIEM platform, designing detection rules, and leading incident response investigations. You will also oversee security for application stacks involving React Native, Node.js, Spring Boot, and Python/Flask, while securing AI/ML systems and payment fraud endpoints. Key skills include proficiency with AWS, GCP, Azure, and identity providers like Okta or Entra ID to ensure robust security posture.

What you'll do

  • Own and maintain infrastructure-as-code across cloud providers using Terraform.
  • Manage the lifecycle of IAM users, keys, and secrets across all environments.
  • Diagnose and resolve production networking issues including load balancers, WAF rules, and DNS.
  • Operate the Elastic Security SIEM platform, including log ingestion and detection rule tuning.
  • Lead security incident response investigations and provide technical oversight for the SOC team.
  • Drive identity governance initiatives and implement authentication hardening measures like MFA and conditional access.
  • Review application code and architecture for security vulnerabilities across web, mobile, and AI/ML systems.
  • Partner with risk teams to investigate and mitigate payment fraud and card-testing attacks.

What we're looking for

  • Must have 5+ years of experience in infrastructure/platform engineering with production ownership in multi-account cloud environments.
  • Must have strong Terraform/IaC experience, including authoring and maintaining shared modules.
  • Must have experience operating a SIEM platform, including log ingestion, detection engineering, and alerting (Elastic Security preferred).
  • Must have solid networking fundamentals including load balancers, security groups, WAF, DNS, and CDN.
  • Must have experience with identity providers and authentication/authorization concepts like SSO, SAML, MFA, and conditional access.
  • Must have demonstrated experience leading or heavily contributing to security incident response.
  • Must have working familiarity with application security practices across modern web, mobile, and backend stacks.
  • Must have a legal right to work in the United States.
