Security Engineer - Vulnerability Management

Klarna makes shopping smoooth. And we do it with flair because shopping is fun. Every day, we help customers, businesses, and partners explore just how smoooth the modern shopping experience can be.


It means we’re constantly changing the game. Always trying out new things. And we encourage our people to do the same. To grow. To develop. Because we don’t believe roles have to stay fixed. Instead we inspire our people to take an irregular career path. As a company of 350 dynamic start-ups, our whole business is built for it. So once you’re in, there’s no telling what will happen next.


Engineering at Klarna is an inspired, customer focused community, dedicated to crafting solutions that redefine our industry. Working in small, highly collaborative Agile teams, you and your team will have a clear mission and ownership of an important outcome that supports Klarna and our customers. At Klarna we optimise for quality, flow, fast feedback, focussing on end-to-end ownership, continuous improvement, testing, monitoring and experimentation. We aim for teams that are inclusive, helpful, and have a strong sense of ownership for the things they build.


Our engineers make some of the most significant decisions for the company and we are looking for bold, open and curious developers. As a Klarnaut, you’ll be inspired to contribute to the growth of Europe’s most highly valued fintech and your work will reach millions of users.


Engineering is rapidly growing and we are looking for new talent to join our Application Security team.


What you will get to do


Security lies at the core of what we do at Klarna. We're looking for people passionate about taking the security of our products to the next level. Our Secure Development & Automation and Offensive Security teams closely collaborate to educate, advise, build and break. We constantly challenge our ways of working to make sure we're keeping up with Klarna's fast-paced development.


We are looking for security engineers with experience from one or more touch points across the secure development lifecycle. We look for engineers with broad experience as well as specialists. We try to find the best home for your specific skill set while providing opportunities to expand your skill-set through cross-training.


We see an ever growing need to ensure the solutions we build are secure. We need to train our internal customers in security, advise through risk assessment and threat modeling, get our hands dirty to help build security automation and tooling support engineering throughout development workflows, and break our products before attackers do.


Our offensive security team is now looking for a hacker that loves breaking stuff. We want to give you the freedom to work across the offensive space where it provides the most value. If you feel at home when innovating and breaking solutions with a focus on cloud environments, this is the role for you.


Some of the things you’ll get to work with
Deliver security assessments to identify, quantify and help mitigate security concerns
Assess the security of Klarna’s through manual assessments and custom automation
Assess the security of our tech stack through whatever means are best suited
Define what we focus on to provide the most value, e.g. various Red-team exercises
Help manage our Bug Bounty program and stakeholders engagement
Improve our engagement process with Engineering via improved tooling and process
Spread awareness of offensive security practices via demos, workshops and training
Have fun and share your knowledge and expertise while doing so



You should have
Experience with penetration testing and other technical security assessments
Experience identifying security issues in code, particularly within Java and Node.js
Experience with building your own tools, particularly Python and Node.js
Experience with cloud, particularly AWS, and modern tech stacks
Experience with working with engineers and within agile development team
Certificates such as OCSP, OSWE, CREST and AWS certificates are appreciated
