Your tasks

The primary activity within the role is to conduct advanced security reviews and penetration tests, generally always together with another colleague. These are performed on a technical level where you will actively look for security vulnerabilities in things like web applications, APIs, mobile devices, client computers, and servers. The methods, tools, and script/coding languages vary depending on your preference as well as what you are testing, but a few examples are: Burp Suite, Nmap, Python, and PowerShell.

Additionally, as a consultant, you will also actively communicate directly with the customer contact to accurately define all requirements, essential details and other necessary information to perform your tasks

You should meet at least three of these requirements

·       Experience in web application penetration testing (experience in all items in the OWASP top 10 as a minimum)

·       Web technologies, both traditional and modern web application frameworks and technologies

·       SQL and databases

·       Experience in penetration testing of complex applications (multiple systems, API's, integrations, etc.)

·       Experience in penetration testing of non-web applications (for example a thick client with custom communication protocols)

·       Understanding of arbitrary programming languages and the ability to identify vulnerabilities in code

·       Understanding of underlying infrastructure and configuration (Windows and Linux)

·       Ability to determine the consequences of a vulnerability based on context

·       Technical report writing & report presentation

And these are optional but great if you know

·       Devops experience

·       Sysadmin experience

·       Full proficiency in at least one programming language

·       Code review experience

·       Ability to present findings to a non-technical audience
