Our client is a global provider of financial market data, managing multiple change programs to deliver high-quality software that connects financial markets worldwide through real-time, high-frequency, low-latency data management systems. These projects are technically demanding and operate in a dynamic environment.

The Real-Time division has initiated a Cyber Security Issues Remediation program to address critical security vulnerabilities across its cloud infrastructure and deployment pipelines. The objective is to remediate identified security issues, harden CI/CD pipelines, implement security best practices, and strengthen the overall security posture of the Real-Time platform on AWS.

Responsibilities

Identify and resolve security vulnerabilities in AWS infrastructure, applications, and CI/CD pipelines.

Build and optimize CI/CD pipelines to support automated and secure software delivery.

Deploy and manage applications using Docker and Kubernetes.

Manage secrets, privileged access, and artifact repositories.

Implement security, monitoring, logging, and disaster recovery best practices.

Collaborate with engineering and security teams to improve platform reliability and security.

Support cloud migrations and infrastructure hardening initiatives.

Skills

Must have

Strong experience in DevOps engineering (10+ years)

Experience with AWS security services and compliance frameworks

Strong experience containerizing applications using Docker

Hands-on experience deploying and managing Kubernetes clusters (preferably Amazon EKS)

Hands-on experience with HashiCorp Vault and PAM (Privileged Access Management)

Strong experience designing and implementing CI/CD pipelines using GitLab CI/CD, Jenkins, Azure DevOps, or GitHub Actions
