Pentester
Scope, recon, exploit, write the report nobody reads. Repeat next engagement.
Far harder to break into than the marketing suggests, and the day-to-day is less glamorous than the highlight reels. Worth it only if the craft genuinely pulls you.

- Entry
- £32–52k
- Senior
- £95–135k
- You've already got writeups, CTF solves or HTB ranks that prove the hands work
- You'll happily write a 40-page report for every fortnight of testing
- You can sit with not knowing the answer for days at a time
- You enjoy reading other people's code more than writing your own
- Your only credential is a cert and a LinkedIn headline
- You want offensive work without the consultancy travel or scoping calls
- You don't like being wrong in writing, in front of clients, every quarter
What "doing well" looks like in the seat
- Your reports get used as templates by the rest of the team
- You find things that aren't on the checklist
- Clients ask for you by name on the rebook
- You're shipping tooling or research between engagements, not just consuming both
The pay-to-skill ratio is worse than people think. Senior pentesters in the UK earn less than mid-level cloud engineers, and the ladder above mid is narrow: principal, lead, or out into red team and research. Consultancy life is also harder on home routine than it looks from outside, with travel, late report nights and an endless retest queue. If you're in it for the craft, the salary is fine. If you're in it for the salary, almost every other security path pays better.
