🎯 The Role

The Cybersecurity Engineer designs, implements, and operates the security controls that protect the organization's systems, networks, applications, and data. This is a hands-on, technical role that partners closely with IT, DevOps, and engineering teams to identify risk, respond to incidents, and continuously strengthen the company's security posture. The ideal candidate combines deep technical expertise with strong communication skills, translating complex security concepts into practical guidance that enables the business to move fast without compromising security.

✅ Key Responsibilities

• Design, implement, and maintain security controls across cloud, on-premises, and SaaS environments
• Deploy, configure, and manage security tools such as SIEM, EDR, IDS/IPS, vulnerability scanners, and DLP platforms
• Monitor security alerts and telemetry, investigate suspicious activity, and respond to incidents in accordance with defined SLAs
• Tune detection rules and correlation logic to reduce false positives and improve signal quality
• Perform root-cause analysis on security events and implement corrective, preventative actions
• Maintain and continuously improve security architecture diagrams, network segmentation, and control documentation
• Participate in, and where appropriate lead, incident response efforts across the full lifecycle: detection, containment, eradication, and recovery
• Triage alerts, contain active threats, and coordinate cross-functional recovery activities
• Develop, test, and maintain incident response playbooks, runbooks, and communication procedures
• Conduct post-incident reviews and blameless retrospectives, and drive follow-through on recommended improvements
• Serve in an on-call rotation to support after-hours security incidents as needed
• Perform recurring vulnerability scanning, penetration test coordination, and risk assessments across infrastructure and applications
• Validate findings, assess business risk and exploitability, and prioritize remediation with asset owners
• Conduct threat modeling and security architecture reviews for new systems and major changes
• Track remediation through to closure and report on residual risk to stakeholders
• Secure cloud infrastructure (AWS, Azure, and/or GCP) and containerized/orchestrated environments (Docker, Kubernetes)
• Implement and maintain IAM policies, secrets management, and least-privilege access models
• Partner with engineering teams to embed security scanning (SAST, DAST, SCA, container scanning) into CI/CD pipelines
• Review application designs, architecture, and code for security risks; provide actionable remediation guidance
• Deploy, configure, and tune Web Application Firewalls (WAF) to protect public-facing applications and APIs
• Develop and maintain WAF rule sets and policies to mitigate OWASP Top 10 risks, bot traffic, and DDoS attempts
• Analyze WAF logs and blocked/allowed traffic to identify attack patterns and reduce false positives/negatives
• Partner with application teams to onboard new services behind the WAF and validate rule coverage before go-live
• Assist with audits and compliance initiatives
• Collect and organize audit evidence, and help maintain security policies, standards, and documentation
• Support vendor risk assessments and third-party security reviews
• Help maintain the organization's risk register and control mapping
• Work closely with IT, DevOps, and product teams to design and implement secure solutions
• Provide practical, risk-based security guidance that enables delivery rather than blocking it
• Contribute to security awareness and training initiatives, including phishing simulations and onboarding content
• Act as a security point of contact and subject-matter resource for engineering and business teams

📌 Required Qualifications

• 3–5+ years of experience in a cybersecurity, security engineering, or related technical IT role
• Hands-on experience with SIEM, EDR, and vulnerability management tooling
• Working knowledge of cloud platforms (AWS, Azure, or GCP) and cloud security best practices
• Experience configuring and managing Web Application Firewalls
• Solid understanding of networking fundamentals, TCP/IP, firewalls, and network segmentation
• Familiarity with common frameworks and standards such as NIST CSF, MITRE ATT&CK, CIS Benchmarks, or ISO 27001
• Experience scripting or automating tasks in Python, Bash, or PowerShell
• Strong analytical and problem-solving skills, with the ability to work calmly under pressure during incidents
• Excellent written and verbal communication skills
