About the role

We are now looking for a Penetration Tester for our Engineering Team. This position can be based in Sweden, the Netherlands, or Finland. You will be joining a team of security specialists advising our clients as they rely on us to find vulnerabilities in their network setups, web and mobile applications, physical devices or cloud deployments among others.

As a Penetration tester, your main task is to perform penetration testing against many different types of applications and networks. In addition, you will have an opportunity to work with some very security-minded colleagues and clients. Your daily work will include:

  • Experience with hacking tools such as Burp Suite, NMAP, Nessus, Metasploit or Core Impact.
  • Experience analysing code to help drive white box testing assessments.
  • Experience with security standards such as OWASP’s M/ASVS.

The following elements are considered as a bonus:

We are looking for people who embrace our ways of working – always aiming for higher quality and finding new ways to improve ourselves and our performance. You are a self-driven team player who is willing to learn new things and share your knowledge and experiences.

Your daily work will also include help developing our products to ensure the continuous quality of our products. This is a full-time position, and locations can be Sweden: Stockholm or Uppsala, the Netherlands: Amsterdam, Finland: Espoo, Turku or Jyväskylä.
