AppSec Engineer
Threat-modelling features, reviewing code, hunting bugs in web/mobile, building paved roads with devs.
Best-paid security lane for engineers who can read code. Bounty hunters underestimate the threat-modelling discipline.
Read the full role verdict and reasoning
Application security helps engineering teams address threats in design and implementation.
- Domain
- Cybersecurity
- Entry
- Not mapped
- Senior
- Not mapped
- You can read code in two or three production languages without help
- You enjoy threat modelling and secure design conversations
- You're comfortable being embedded with engineering teams who don't always like you
- You can pick your battles, AppSec is mostly choosing what to ignore
- You don't have real coding background, the seat will expose you
- You expect to gate releases, that model died a decade ago
- You'd struggle being the person who pushes back on shipping things
What "doing well" looks like in the seat
- Developers ask for your input early in design, not at PR time
- Your SAST and SCA pipelines stay tuned and trusted
- You can ship a secure code review faster than the deadline expects
- You've killed a check that wasn't earning its keep
Advice needs a path into delivered code. Check collaboration with developers, remediation ownership and how security testing reflects the application's actual risks.
