Varför ett CV för det här jobbet?
- De ser det de bad om, först. Den erfarenhet som matchar annonsen kommer först, med annonsens egna ord, så att den som skummar hittar det på några sekunder.
- Det tar sig förbi programvaran. Många större arbetsgivare använder program som rangordnar CV:n efter hur väl de matchar annonsen, ofta innan någon har läst dem.
- På annonsens språk. En annons skriven på engelska får ett CV på engelska, även när ditt är på svenska.
- Dina fakta, inget påhittat. Din egen erfarenhet, omordnad och omformulerad. Det annonsen vill ha och ditt CV inte visar listas så att du kan lägga till det, bara om det stämmer. Du kontrollerar det innan du skickar det.
About the role
Klarna runs on financial infrastructure that has to hold up against real attackers, not hypothetical
ones. As an Engineer within the security track, you'll work on the systems and practices that
keep that infrastructure safe - finding weaknesses before someone else does, and building the
tools and controls that make the whole engineering organization more secure by default.
You'll work closely with engineers across other teams, helping them understand risk in their own
systems rather than just handing them a list of findings.
What you'll do
● You'll look for vulnerabilities in Klarna's systems and help fix the ones you find.
● You'll build and maintain tools that make it easier for other engineering teams to write
secure code.
● You'll review designs and code from other teams with security in mind, and flag risks
before they ship.
● You'll help respond when something goes wrong, working through what happened and
what needs to change.
● You'll use AI tools as part of your everyday workflow, not as a separate add-on step.
Who you are
● You've written code in Java, JavaScript, or Python, whether through a job, an internship,
or your own projects.
● You understand common security vulnerabilities and how attackers actually exploit them,
not just their names.
● You can explain a security risk to another engineer in terms they can act on, not just flag
it and move on.
● You're comfortable digging into a system you didn't build to understand how it works.
● You want regular feedback on your work and you act on it.
Bonus points for
● A degree in Computer Science, Engineering, or a related field.
● Experience with penetration testing, threat modeling, or security tooling.
● Participation in bug bounty programs or CTF competitions
