AWS Application Security engineer

Role Summary

We are seeking an experienced Application Security Engineer to secure applications built and operated on AWS. You will embed security across the SDLC — from secure design and code review through CI/CD integration, runtime protection, and incident response — working closely with development, DevOps, and client security teams.

Key Responsibilities

• Perform threat modeling and secure design reviews for applications and microservices deployed on AWS (EC2, ECS/EKS, Lambda, API Gateway).
• Integrate and operate security tooling in CI/CD pipelines: SAST, DAST, SCA/dependency scanning, container image scanning, and IaC scanning.
• Configure and manage AWS-native security services: WAF, Shield, GuardDuty, Inspector, Security Hub, KMS, Secrets Manager, IAM.
• Define and enforce least-privilege IAM policies, secrets management standards, and encryption (at rest/in transit) across workloads.
• Conduct secure code reviews and vulnerability triage; partner with dev teams on remediation and secure coding practices (OWASP Top 10, CWE).
• Harden infrastructure-as-code (Terraform/CloudFormation) using policy-as-code (OPA, Checkov) and guardrails (SCPs, Config rules).
• Support penetration test coordination, findings remediation, and audit/compliance requirements (SOC 2, ISO 27001, PCI-DSS as applicable).
• Respond to application-layer security incidents; contribute to detection rules and runbooks.
• Mentor engineers and champion DevSecOps culture across delivery teams.

Required Skills & Experience

• 8+ years in application security / product security, with 3+ years securing workloads on AWS.
• Hands-on expertise with AWS security services: IAM, WAF, GuardDuty, Inspector, Security Hub, KMS, Secrets Manager, CloudTrail.
• Strong knowledge of OWASP Top 10, API security, authentication/authorization patterns (OAuth 2.0, OIDC, SAML).
• Experience with security tooling: SonarQube/Checkmarx/Veracode (SAST), Snyk/Prisma/Aqua (SCA & containers), Burp Suite/OWASP ZAP (DAST).
• Proficiency in at least one language for automation — Python, Go, or similar; ability to read Java/Node.js/.NET application code.
• Experience securing containerized (Docker, EKS/ECS) and serverless (Lambda) architectures.
• IaC security: Terraform or CloudFormation with Checkov/tfsec/cfn-nag.
• CI/CD security integration: GitHub Actions, GitLab CI, Jenkins, or AWS CodePipeline.
• Certifications: AWS Certified Security – Specialty (strongly preferred); CSSLP, OSWE, or CISSP.

Preferred Qualifications

• Experience with CNAPP platforms (Wiz, Prisma Cloud, CrowdStrike Falcon Cloud).
• Threat modeling frameworks (STRIDE, PASTA) and secure SDLC program experience.
• Prior work in a client-facing or consulting/delivery environment with enterprise customers.
• Exposure to compliance frameworks: SOC 2, ISO 27001, PCI-DSS, HIPAA, FedRAMP.

Soft Skills

• Strong communication — able to explain risk and remediation to both engineers and business stakeholders.
• Pragmatic, risk-based mindset; balances security rigor with delivery velocity.
• Self-driven; comfortable operating in ambiguous, fast-moving programs.
