Security Engineer Tiers

Security Engineer roles are often structured into tiers or levels similar to SOC analysts, but with a focus on building, hardening, and maintaining security infrastructure rather than alert triage.

Here’s how Cybersecurity Engineer tiers typically break down:

🧰 Tier 1 – Junior / Associate Security Engineer

Entry-level engineering role focused on assisting with configuration, monitoring, and operational tasks under supervision.

🔍 Responsibilities:

  • Assist with firewall, endpoint, and log ingestion configurations
  • Run vulnerability scans and report findings
  • Manage user access reviews and basic IAM tasks
  • Help maintain patching schedules
  • Monitor dashboards and ticket queues

🧠 Skills:

  • Basic knowledge of networking and protocols (TCP/IP, DNS, HTTP)
  • Familiarity with firewalls, SIEMs, and antivirus tools
  • Exposure to scripting (PowerShell, Bash, or Python)
  • Understanding of the CIA triad and basic security principles

👣 Goal:

Build foundational hands-on experience with common tools and security practices.


🛠️ Tier 2 – Security Engineer / Systems Security Engineer

Mid-level engineer responsible for deploying and maintaining key security infrastructure and supporting incident response.

🔍 Responsibilities:

  • Configure and tune SIEM, EDR, DLP, WAF, and vulnerability management tools
  • Write detection rules and alerts (e.g. SPL, KQL, Sigma)
  • Troubleshoot security tools and integrate log sources
  • Assist with incident response and threat detection
  • Automate repetitive tasks using scripts or SOAR
  • Perform cloud security reviews (AWS, Azure)

🧠 Skills:

  • Comfortable with Linux and Windows internals
  • Proficient in log formats, detection tuning, and SIEM query languages
  • Basic to intermediate scripting (Python, PowerShell)
  • Familiar with frameworks like MITRE ATT&CK, NIST 800-53, CIS Controls

📈 Goal:

Act as a reliable, hands-on defender capable of building detection and hardening systems.


🧠 Tier 3 – Senior Security Engineer / Security Architect

Advanced-level role that designs secure systems, leads engineering projects, and mentors others.

🔍 Responsibilities:

  • Architect and deploy enterprise-grade security solutions (SIEM, SOAR, ZTNA, IAM)
  • Lead threat modelling and risk assessments
  • Align infrastructure to frameworks like NIST, ISO 27001, or PCI
  • Guide DevSecOps practices and CI/CD pipeline security
  • Mentor junior engineers and contribute to incident response and architecture reviews
  • Collaborate with red/purple teams to improve detection and coverage

🧠 Skills:

  • Deep experience with cloud security (AWS, Azure, GCP)
  • Network security architecture and segmentation
  • Security automation and infrastructure-as-code (e.g. Terraform, Ansible)
  • Proficient in multiple programming/scripting languages
  • Strong understanding of identity, access, and privilege models

📈 Goal:

Shape long-term security strategy, infrastructure, and detection capability.
