🎯 Role Definition

A Security Engineer is the hands-on architect and guardian of an organization's digital defense systems. This role is fundamentally technical, focusing on designing, building, and maintaining the infrastructure that protects sensitive data and critical systems from cyber threats. More than just a gatekeeper, the Security Engineer acts as a proactive problem-solver, constantly analyzing the threat landscape, identifying vulnerabilities, and engineering robust solutions to mitigate risks. They work at the intersection of software development, network administration, and cybersecurity policy, ensuring that security is not an afterthought but a foundational component of all technology initiatives. This position is vital for maintaining operational integrity, customer trust, and regulatory compliance in an increasingly complex digital world.

Core Responsibilities

Primary Functions

  • Design, implement, and manage a comprehensive suite of security tools and technologies, including firewalls, intrusion detection/prevention systems (IDS/IPS), SIEM, and endpoint protection solutions.
  • Conduct regular and thorough vulnerability assessments, penetration tests, and security audits to proactively identify and remediate weaknesses in our infrastructure, applications, and networks.
  • Engineer and maintain secure network architectures, including segmentation, access controls, and VPN configurations to enforce the principle of least privilege.
  • Develop, automate, and orchestrate security operations workflows to improve detection and response times, often using scripting languages like Python or PowerShell.
  • Serve as a key member of the incident response team, leading technical investigation, containment, eradication, and recovery efforts during security incidents.
  • Configure and fine-tune Security Information and Event Management (SIEM) systems to ensure accurate and timely threat detection, and develop custom correlation rules.
  • Manage and administer identity and access management (IAM) solutions, including multi-factor authentication (MFA), single sign-on (SSO), and privileged access management (PAM).
  • Harden operating systems, applications, and network devices according to industry best practices and internal security standards (e.g., CIS Benchmarks).
  • Evaluate, recommend, and implement new security technologies and vendor solutions through rigorous proof-of-concept testing and analysis.
  • Collaborate with development and DevOps teams to integrate security into the CI/CD pipeline (DevSecOps), performing static (SAST) and dynamic (DAST) application security testing.
  • Develop and maintain comprehensive documentation for security systems, procedures, and incident response playbooks.
  • Monitor security access and conduct regular reviews of user permissions and system configurations to ensure compliance with security policies.
  • Lead the technical response to security questionnaires and audits from clients and regulatory bodies, providing evidence of controls.
  • Research emerging threats, vulnerabilities, and attack vectors to keep the organization's defense strategy current and effective.
  • Architect and manage security solutions for cloud environments (AWS, Azure, GCP), including VPC configurations, security groups, and cloud-native security tools.
  • Implement and manage data loss prevention (DLP) technologies to monitor and protect sensitive data in transit, at rest, and in use.
  • Conduct forensic analysis of compromised systems to determine the root cause and extent of a breach.
  • Manage the lifecycle of digital certificates and public key infrastructure (PKI) to ensure secure communication.
  • Create and maintain metrics, dashboards, and reports on the health of the security program for technical and executive audiences.
  • Participate in the design and execution of disaster recovery and business continuity plans from a security perspective.

Secondary Functions

  • Develop and deliver security awareness training materials and phishing simulations to educate employees on best practices.
  • Participate in an on-call rotation to provide 24/7 response to critical security alerts and incidents.
  • Mentor junior security analysts and engineers, providing technical guidance and support.
  • Contribute to the development and enforcement of the organization's information security policies, standards, and procedures.
