Security Code Auditor (m/f/d)

X41 is seeking experienced professionals to join our team as code auditor. Your task would be to find security-relevant bugs in diverse codebases, spanning different programming languages and customers. Techniques can include running analysis tools as an initial check, applying fuzzing where applicable, and of course also using your own expertise in manually reading the code for logic issues or other types of problems. Projects may be open source or proprietary. To see some of our published work in this area, see our blog posts about Envoy, libjpeg-turbo, and Git.

It is possible to work fully remote, especially as you gain experience in the role, though we are even more excited for candidates that want to join us in the Aachen office. The exact number of office days per week is very flexible.

Speculative Application

Always feel free to reach out as a security professional or if you have related expertise and are looking to make a career change. As a small team, we do not always have space to fully support junior, lateral entrant, or internship positions, but are always happy to get to know each other and see if there is a role for you in the organization.

Apply

If you are ready to apply, please email us at info@x41-dsec.de. We typically expect a CV or resume (in English or German) together with a short description in the email of what you are looking for in this position. You will always hear back from us, typically within a few days and often with a proposal for an online meeting to get to know each other.

We look forward to receiving your application and potentially welcoming you to the X41 team!
