What does a Security Engineer do?
Security engineers protect the business from real-world adversaries. The role has split into application security (AppSec — secure SDLC, code review, threat modeling), cloud security (IAM, network segmentation, posture management), and detection engineering (SIEM rules, threat hunting). Pure pen-testing is increasingly contracted out; in-house security engineering is the durable career path. AI has changed the threat surface: prompt injection, model exfiltration, and supply-chain attacks via training data are real and underdefended.
A typical day
- Threat-model a new payment integration before it goes to prod
- Triage a SOC alert — likely a false positive but worth 30 minutes
- Pair with a backend engineer on a tricky auth change
- Run a red-team exercise on the new AI feature
- Update the org's security policy in response to a new compliance requirement
Step-by-step roadmap
3 phases. Plan ~14 months at 14h/week.
Security foundations
OWASP Top 10, TLS, OAuth, network protocols, Linux hardening. Plus one programming language strong enough to write tools.
- Complete a CTF or HackTheBox path (intermediate level)
- Run a SAST tool on one of your projects and fix the findings
- Set up a hardened Linux server with proper firewall rules
AppSec + cloud
Code review for security, threat modeling, cloud IAM (AWS, GCP, or Azure), and the security side of CI/CD.
- Threat-model one real production system end-to-end
- Find and report a security issue (responsible disclosure or bug bounty)
- Get a cloud security certification (AWS Security Specialty or equivalent)
Detection + offensive
SIEM tooling, detection-as-code, red-team exercises, and the offensive skills that make defense credible.
- Write a detection rule that catches a real attack pattern
- Pass OSCP or an equivalent hands-on cert
- Lead one tabletop exercise with the engineering leadership

Why this role matters in 2026
AI prompt-injection and model-supply-chain attacks are real. Security engineers who can defend AI systems (not just web apps) are scarce and well-paid.
