Step-by-step roadmap to your first Security Engineer role

1

Build software engineering fundamentals

6–12 months

Security engineers who can read and write code in Python, Go, or Java are significantly more effective and better paid. You need to understand how applications are built to understand how they break.

2

Master application security (AppSec) concepts

2–3 months

OWASP Top 10, secure coding practices, threat modelling, SAST/DAST tools, and vulnerability management. Web Application Hacker's Handbook is the definitive reference.

3

Practice offensive security in labs

3–6 months

HackTheBox Pro Labs, OSCP preparation, and real CVE research. Offensive skills make defensive engineers dramatically better at finding real vulnerabilities vs. just checking compliance boxes.

4

Earn OSCP or CEH certification

3–6 months

OSCP (Offensive Security Certified Professional) is the most respected hands-on security credential. CEH is broader and more accessible as a starting point. CompTIA PenTest+ bridges the gap between Security+ and OSCP.

5

Build detection and response skills

2–3 months

SIEM, log analysis, incident response playbooks, and threat hunting are the defensive complements. Security engineers who can both attack and defend are rare and highly paid.
