Job Description

Oracle's Software Assurance organization has the mission is to make application security and software assurance, at scale, a reality. We are an inclusive and diverse team of high calibre application security researchers, distributed globally, who thrive on new challenges. We are seeking experienced, passionate, and talented security researchers who have genuine excitement for and interest in security to work on a critical greenfield software assurance project collaboratively with our cloud and mobile engineering teams. You must relish the challenge of assessing large, complex software products. Creativity is highly valued; being able to find novel bugs and stitch them together to create something greater than the sum of their parts is essential in this role.

Work You'll Do

As a member of our team, you will be responsible for planning and delivering in depth security assessments across a variety of products and services. Your next project could be anything from source code review of backend services, to static and dynamic analysis of a mobile application, to review or creation of technical security designs. Responsibilities include:

  • Scope and execute security assessments across a broad range of on-premise software, mobile applications, cloud services and infrastructure
  • Perform in-depth security assessments using your code review skills, leveraging results from other assessments such as static and dynamic analysis
  • Create testing tools to help engineering teams identify security-related weaknesses
  • Collaborate with engineering teams to help them triage and fix security issues
  • Keep yourself abreast of new TTPs (Tactics, Techniques & Procedures) of the attackers, mimic them in your security assessments and/or quickly react to new threat scenarios to provide continuous security assurance
  • Mentor junior members of the team in software security as a role model
  • What You'll Bring
  • Aptitude for self-study, setting and achieving long term goals (for example, learning an unfamiliar programming language)
  • Ability to effectively assess and communicate risks and appropriate levels of urgency to management and engineering staff
  • Excellent organizational, presentation, verbal, and written communication skill
  • This role does not require access to a cleared work environment. Security clearances are not required, and active clearances cannot be sponsored.

Nice to Have

  • Experience working in a large cloud or Internet software company

  • Proficiency with one or more programming languages, preferably Go, Java, Python or C/C++

  • Ability to perform manual source code reviews in one of the aforementioned languages, or assisted review with code analysis tools such as CodeQL

  • Experience navigating and working with extremely large codebases is also highly desirable

  • Experience using common security assessment tools and techniques in one or more the following categories:

  • Proficiency in performing mobile application assessment (iOS / Android)

  • Reverse Engineering (e.g., IDA Pro/Ghidra/Radare2) and debugging codebase with the objective to find security gaps/vulnerabilities

  • Proficiency in Fuzzing (e.g., Jazzer/AFL/Peach) techniques to inject invalid, malformed, or unexpected inputs into a system to reveal software defects and vulnerabilities.

  • Proficiency in advanced Mobile, API, Infrastructure, Web Application penetration testing to find vulnerabilities such as insecure Java/PHP/PHAR deserialization, XXE, HTTP desynchronization, cryptography weaknesses (exploiting ECB Shuffling, CBC Bit Flipping etc.), Mass assignments, template injections, HTTP/2 and HTTP/3 protocol issues etc.

  • Knowledge of common vulnerabilities in different types of software and programming languages, including:

  • How to test for/exploit them

  • Real world mitigations that can be applied

  • Familiarity with vulnerability classification frameworks (e.g., OWASP Top 10)

  • Ability to threat model systems/applications/platforms to assess design and find flaws that can be exploited

What We'll Give You

  • A team of very skilled and diverse personnel across the globe
  • Exposure to mind blowing large-scale cutting-edge systems
  • The resources of a large, global operation while still having the small, start-up feel of a smaller team day to day
  • Develop new skills and competencies working with our vast cloud product offerings
  • Ongoing extensive training and skills development to further your career aspirations
  • Incredible benefits and company perks
  • An organization filled with smart, enthusiastic, and motivated colleagues
  • The opportunity to impact and improve our systems and delight our customers
