Job Description
We are looking for a senior engineer who can operate at the intersection of cloud infrastructure, platform engineering, and security operations. This is a hybrid role for an engineer who is equally comfortable debugging a Terraform module, tuning a SIEM detection rule, and leading an incident response investigation. You'll be a primary technical escalation point for both platform reliability and security incidents across all cloud environments.
What You'll Do
Cloud Infrastructure & Platform Engineering
Manage IAM users, keys, and secrets lifecycle (rotation, storage in Parameter Store/Secrets Manager, cross-environment consistency)
Diagnose and resolve production networking and infrastructure issues: load balancer health checks, security groups, WAF rules, CDN and origin access, DNS, and container orchestration
Administer access across supported platforms (e.g., AWS, GCP, GitHub, etc.) and internal developer tooling
SIEM & Detection Engineering
Own and operate the organization's Elastic Security (SIEM) platform end-to-end: cluster upgrades, agent/integration management, and log ingestion pipelines (cloud audit logs, identity provider logs, payment/fraud logs, WAF logs)
Design, build, and tune detection rules and alerting workflows, including integrating SIEM alerts into team communication channels (e.g., Slack)
Security Operations & Incident Response
Provide technical leadership and day-to-day oversight for the SOC team, including prioritization, escalations, investigation quality and mentoring
Lead investigations into anomalous authentication activity, account compromise, and suspicious network traffic, including coordinating remediation (session revocation, credential resets, user outreach)
Identity, Access & Compliance
Design and implement authentication hardening measures: conditional access policies, MFA/authentication strength requirements, and legacy protocol deprecation (e.g., legacy SMTP auth)
Application, AI & Code Ownership
Hold end-to-end security ownership across the organization's core application stack, spanning front-end (React Native, React Web), back-end (Node.js, Spring Boot/Java, Python/Flask), and AI/ML systems
Review code and architecture for security vulnerabilities (e.g., dependency/supply-chain risk, secrets handling, authN/authZ flaws, insecure API design) across mobile, web, and service layers
Serve as the security point of contact for engineering teams building on React Native, React Web, Node.js, Spring Boot, and Python/Flask, ensuring consistent security posture regardless of language/framework
Own the security posture of AI/ML systems and LLM-powered features: model access controls, data governance for training/prompt data, prompt injection and jailbreak risk, and secure integration with third-party AI APIs and vendors
Fraud & Payments Security
Qualifications
Required:
Solid networking fundamentals: load balancers, security groups, WAF, DNS, CDN
Experience with identity providers (Entra ID/Azure AD, Okta, or similar) and authentication/authorization concepts (SSO, SAML, MFA, conditional access)
Working familiarity with application security practices across modern web/mobile and backend stacks (e.g., React/React Native, Node.js, Java/Spring Boot, Python/Flask) — able to read code, understand architecture, and identify security risk even if not writing production application code day-to-day
Preferred:
Hands-on development or code review experience in React Native, React Web, Node.js, Spring Boot/Java, or Python/Flask
Experience with SAST/SCA tooling (e.g., GitHub Advanced Security, Snyk, SonarQube) and integrating security scanning into CI/CD
What Success Looks Like
Cross-functional partners (data, application, payments teams) see this role as a trusted, responsive technical partner
Pay Transparency: $145K - $175K
