THE OPPORTUNITY

Join our team as a Security Engineer working within an agentic SOC environment. This role is designed for someone who is ready to grow beyond traditional analyst responsibilities and move deeper into security engineering, automation, cloud security, detection engineering, and AI‑assisted security operations.

You will help build, operate, and improve a modern SOC that uses automation, agentic workflows, AI‑assisted investigation, and security engineering practices to improve detection, triage, response, and overall security visibility. This is a hands‑on role for someone who enjoys solving technical problems, improving systems, and building security capabilities rather than only monitoring alerts.

The ideal candidate has 2–3 years of cybersecurity experience, a strong SOC foundation, hands‑on AWS knowledge, Python proficiency, and experience working with SIEM data and log pipelines. We are looking for someone motivated, curious, and eager to grow into a stronger security engineer within a modern, engineering‑driven SOC model.

RESPONSIBILITIES:

• Security Engineering: Build, maintain, and improve security workflows, integrations, detection processes, and operational tooling within an agentic SOC.
• Agentic SOC Operations: Work with automation, AI‑assisted workflows, and agent‑based capabilities that support alert triage, investigation, enrichment, and response.
• SIEM Log Flow Development: Help design, configure, maintain, and troubleshoot log ingestion flows into the SIEM from AWS, applications, infrastructure, endpoint tools, and security platforms.
• Detection Engineering: Create, tune, and maintain detection rules, alert logic, dashboards, playbooks, and investigation workflows.
• Python Automation: Develop Python scripts and automations for alert enrichment, data processing, reporting, workflow improvement, and security operations support.
• Cloud Security Monitoring: Support cloud security logging, monitoring, IAM reviews, and cloud detection use cases.
• SOC Operations: Review, analyze, and correlate security alerts and logs to identify suspicious activity and support investigations.
• Incident Response Support: Assist with security event investigations, escalation, containment, remediation, and post‑incident improvements.
• Process Improvement: Help improve SOC processes, playbooks, detection coverage, documentation, and response workflows.
• Cross‑Functional
  
  Collaboration:
  
  Partner with security, cloud, IT, and engineering teams to improve visibility, reduce risk, and strengthen security operations.

REQUIRED QUALIFICATIONS:

• Experience: 2–3 years of experience in cybersecurity, SOC operations, security engineering, cloud security, detection engineering, or incident response.
• AWS Knowledge: Working knowledge of AWS services, cloud security fundamentals, logging, monitoring, IAM, and basic cloud architecture.
• AWS Certification: AWS entry‑level certification required at minimum, such as AWS Certified Cloud Practitioner. AWS Solutions Architect – Associate or AWS Security Specialty is a plus.
• Python Proficiency: Hands‑on proficiency with Python for scripting, automation, data processing, security tooling, or workflow development.
