Senior Cloud Security Engineer - DevSecOps

Job Description About the Role: We are seeking a highly experienced and action-oriented Senior Cloud Security Engineer to join the Grand Central Platform team. This role focuses on developing and maintaining the robust security posture of platforms key to our business, including the IPaaS (Integration Platform as a Service) and the AI Agentic platform, which serve both internal employees and external financial institution customers.

The ideal candidate possesses a strong technical and hands-on approach. You won’t just identify vulnerabilities and explain risks; you will actively collaborate with the team to implement fixes. Our team champions the principle of “security as everyone’s responsibility,” adhering strictly to established security standards and conventions.

• Propose and drive security initiatives, collaborating across various teams within the company, and actively participate in the Security Guild.
• Architecture, Design & Cloud Security Implementation (Azure Focus):
• Collaborate with architects to enforce the secure by design principle for new Platform components.
• Design, implement, and maintain secure cloud infrastructure and controls within Azure environments. Ensure compliance with relevant security standards and regulations through regular security assessments and risk analyses.
• Implement and maintain cloud security best practices across Azure environments.
• Bring deep expertise to designing and developing architectures that enhance visibility, detection, mitigation, and observability.
• Threat and Risk Management:
• Conduct comprehensive risk assessments, threat modeling, and penetration testing.
• Identify vulnerabilities and recommend strategic mitigation strategies for cloud security threats.
• Secure cloud network architectures (Networking & Security).
• Identity, Access, and Monitoring:
• Design and enforce least privilege access and secure authentication mechanisms (Identity & Access Management - IAM).
• Maintain security monitoring tools (SIEM, CSPM, EDR), investigate threats, and manage security incident response.
• DevSecOps & Automation:
• Embed security into CI/CD pipelines using DevSecOps methodologies.
• Automate security compliance checks and vulnerability assessments.
• Utilize expertise in Terraform or OpenTofu for Infrastructure as Code (IaC) security automation.
• Collaborate with development teams to integrate security into the Secure SDLC, promoting secure coding practices and regular security testing.

Required Qualifications

• 8+ years of hands-on experience in cloud security, DevSecOps, or cloud engineering with a dedicated security focus.
• Deep expertise in Azure cloud security architecture and services.
• Strong experience with Cloud IAM, specifically: Azure AD, RBAC, PIM, and Conditional Access.
• In-depth knowledge of IAM, RBAC, and access policies in Azure.
• Proven experience in designing and maintaining cloud-based IaaS, PaaS, and SaaS environments.
• Expertise in Terraform or OpenTofu for IaC security automation.
• Experience with security monitoring tools SIEM, CSPM, EDR (e.g., Azure Sentinel, Defender for Cloud).
• Strong proficiency in scripting and automation (Python, Go, Bash).
• Solid networking knowledge, including firewalls, VPNs, VNET peering, and WAF.
• Experience in DevSecOps and embedding security into CI/CD pipelines, along with a strong understanding of Secure SDLC.
• Familiarity with security compliance standards (e.g., NIST, CIS, ISO 27001, SOC 2).
• Familiarity with LLM/AI system vulnerabilities (e.g., prompt injection, data poisoning, adversarial attacks).
• Demonstrated ability to identify, triage, and resolve security issues across traditional and AI-based systems. Offensive security experience is a significant plus.
