- Threat Detection & Incident Response: Participate in an on-call rotation to respond to security incidents, investigate vulnerabilities, and implement proactive measures to prevent future threats. Work closely with engineering teams to remediate security risks.
- Monitoring & Logging for Security: Improve observability by implementing security monitoring solutions, logging best practices, and alerting mechanisms to detect anomalies and suspicious activity.
- Access Control & Identity Management: Manage IAM roles, permissions, and policies to ensure least privilege access and enforce security controls across cloud and internal systems.
- Collaboration & Security Advocacy: Work with DevOps, engineering, and compliance teams to integrate security best practices into the software development lifecycle (SDLC) and promote a security-first culture.
- Continuous Security Improvement: Identify and mitigate security vulnerabilities, conduct security assessments, and implement automated security scanning and hardening techniques.
Who You Are
- Experienced in SecOps & SRE: You have 5+ years of experience in Security Operations, Site Reliability Engineering, or DevSecOps, with a strong understanding of cloud security, system reliability, and automation.
- Hands-On with Security Tools & Cloud Platforms: Proficient with AWS security services, GitHub security controls, Terraform for secure infrastructure provisioning, and Ansible for automated security configurations.

- Proactive in Security Monitoring & Hardening: Strong background in logging, monitoring, and anomaly detection using tools like SIEMs, intrusion detection systems (IDS), and cloud-native security solutions.
- Experience working with development teams to integrate security best practices into the SDLC (e.g., static and dynamic code analysis).
- Collaborative & Security-Minded: Passionate about working with engineering teams to embed security into CI/CD pipelines, enforce security policies, threat modeling, and risk assessments, and drive a security-first mindset across the organization.
