As a Senior Application & Cloud Security Engineer (IC3), you will take end-to-end technical ownership of our application security posture across Web, Mobile (iOS/Android), and Cloud (AWS) environments. You will be responsible for threat modeling, conducting deep-dive vulnerability assessments (VAPT), embedding automated security gates into CI/CD pipelines, engineering advanced AWS WAF custom rules & perimeter defenses, and leveraging Observability/SIEM platforms for proactive threat detection and incident monitoring.

Key Responsibilities & Core Scope
Web & Mobile Application Security (AppSec)
Web Application Security: Conduct comprehensive manual and automated vulnerability assessments (VAPT) across web platforms and microservice APIs based on OWASP Top 10 and OWASP API Security Top 10.
Mobile Application Security (iOS & Android): Perform static and agile security assessments aligned with OWASP Mobile Application Security (MASVS) — auditing secure data storage, certificate pinning, biometric authentication, deep linking, reverse-engineering resistance, and third-party SDK security.
Secure SDLC & DevSecOps Automation: Integrate, tune, and scale SAST, DAST, and SCA tools (e.g., Semgrep, Checkmarx, Veracode, Snyk, SonarQube, OWASP ZAP, Burp Suite) inside GitHub Actions / GitLab CI pipelines with minimal developer friction.
Threat Modeling: Lead collaborative threat modeling sessions (STRIDE / MITRE ATT&CK;) with developers and architects during sprint planning and architectural design phases.
Vulnerability Remediation: Work directly with product engineering teams to provide code-level remediation guidance, root-cause analysis, and verification testing.
AWS Security Hardening: Architect and maintain hardened AWS multi-account structures (AWS Organizations, Control Tower, SCPs)



aligned with CIS AWS Foundations Benchmarks.
IAM & Secrets Management: Design least-privilege IAM policies, role-based access controls, automated credential rotation, and secure key management via AWS KMS and Secrets Manager.
Container & Kubernetes Security: Enforce runtime protection, image scanning, and network policies for Docker containers and Kubernetes (EKS/ECS) workloads.
Infrastructure as Code (IaC) Security: Automate Terraform security auditing using tools such as Checkov, tfsec, and Trivy before deployments hit production.
Perimeter Defense & WAF Customization
AWS WAF Engineering: Architect, deploy, and fine-tune AWS WAF and Amazon CloudFront security configurations across all edge endpoints.
Custom Rule Development: Write custom regex rules, rate-limiting policies, IP set filtering, and bot control rules to mitigate Layer 7 DDoS, credential stuffing, scraping, and zero-day vulnerabilities.
Security Observability Platforms: Monitor security telemetry across platforms such as Elastic/OpenSearch, AWS CloudWatch, or Coralogix.
Threat Detection & Alerting: Aggregate and correlate security logs (VPC Flow Logs, CloudTrail, ALB logs, WAF logs, GuardDuty findings) to build high-fidelity detection rules and actionable alert dashboards.
Incident Response Support: Assist in triaging security events, performing log forensics,



and automating alert escalations to reduce Mean Time to Detect (MTTD) and Mean Time to Remediate (MTTR).
Compliance Alignment: Provide technical evidence and enforce controls for SOC 2 Type II, ISO 27001, and CIS Benchmarks.
Tooling & Cost Efficiency: Optimize security tool utilization, eliminate redundancy, and identify cloud architecture cost savings.
Mandatory Qualifications (Must-Haves):
Experience: 6–9 years in Application Security, Cloud Security, and DevSecOps.
AppSec Mastery: In-depth knowledge of Web & Mobile (Android/iOS) security testing, API penetration testing, and secure code review.
AWS Cloud Security: Hands-on experience securing AWS services (IAM, VPC, KMS, GuardDuty, Security Hub, S3, EKS/ECS).
WAF & Edge Defense: Proven experience configuring AWS WAF / CloudFront, including authoring custom WAF rules, rate limiting, and bot protection.
Observability Experience: Practical experience querying and setting up alerts in modern observability/SIEM tools (e.g., Datadog, Splunk, ELK, CloudWatch, Sumo Logic).
CI/CD Integration: Experience automating SAST/DAST/SCA scanners inside CI/CD pipelines (GitHub Actions, GitLab, Jenkins).
Threat Modeling: Solid track record using STRIDE and MITRE ATT&CK; frameworks for architecture reviews.
Bonus / Good-to-Have (Optional):
Certifications: Relevant offensive/security certifications: OSCP, AWS Certified Security – Specialty, eWPTX, CEH, or CISSP.
Emerging Tech: Experience or research in AI/LLM Security (OWASP LLM Top 10, Prompt Injection defense, RAG security).
Prior experience managing, administering, or launching a Responsible Disclosure Program (VDP) or Bug Bounty program (e.g., HackerOne, Bugcrowd, or internal security policy) is a strong added advantage.
