> What will you do?

Our team of experts constantly work on various topics, such as hardware instrumentation, cryptography analysis and reverse engineering of mobile applications etc.

When they come to you in order to work on vulnerability assessment activities of mobile applications, you jump into your role and conduct penetration testing. You like exchanging with the experts to see how our/eShard services can be improved to provide excellence towards our customers.
As part of our roadmap, you and the team will develop meaningful metrics to reflect the true security posture of the environment, allowing the customer to make educated decisions based on risk. For this, you closely work with the Service Leader who provides guidance and expertise to produce actionable penetration testing reports.
You act as a source of direction, training, and guidance for less experienced staff. You are in charge of performing security design reviews and secure code reviews. During efficient and crisp meetings with the team, you look for ways to exploit vulnerabilities and design solutions to take remedial action. You are also responsible to do research with the aim to break the most recent security frameworks for mobile applications.
You are in charge of developing test modules for our SaaS mobile security testing platform (esChecker). In doing so, you also contribute to Open Source projects.
You will work either remotely or from our office in Pessac, France; it’s important to have a place of work to meet and hang out. Parts of a project may require interacting with customers all over the world. Our office culture is highly technical, our organisation fairly flat and our mindset flexible.
