About the Role

Uber’s Product Security organization is looking for a tech lead (TL) to join our security assessments team.  As a member of our in-house pen-test team, your principle mission will be to ensure the team’s readiness and preparation to conduct grey-box and white-box offensive pen-testing activities against our microservices, applications, infrastructure and data-layer services.  You will work closely with our engineering groups to define pen-test scope, lead assessment engagements, and map assessment findings into engineering plans of action for remediation, ultimately guiding our product security uplift activities.  This is a unique opportunity for an offensive pen-tester who is collaborative, and has a healthy sense of curiosity to join Uber Engineering Security to make real positive impacts to our security posture, and help us improve our security designs in our next-gen of systems and services.

What You Will Do

  • Develop and ensure the assessments teams’ capability to conduct white-box and grey-box offensive penetration testing against Uber’s mobile applications, front-end & back-end micro-services and web services
  • Develop and ensure the assessments teams’ capability to conduct network infrastructure, Public Cloud (AWS and GCP), and data-layer offensive pen-testing
  • Develop and detail the sources and methods required for the assessment team to perform mobile reverse engineering and/or mobile instrumentation of mobile application products for assessments.
  • Assist the assessment team during the active engagements acting as a force-multiplier
  • Teach and mentor junior team members on Techniques, Tactics and Procedures (TTPs) for pen-testing
  • Perform manual source code reviews and audits (manual and SCA/SAST code audits) and/or any needed security research on the product suites undergoing assessment
  • Compile any needed architectural documentation or recovery for grey-box or white-box assessment activities
  • Assist in scheduling and coordinating both internal and external assessments activities
  • Be a subject matter expert and ambassador to Uber Engineering for secure coding practices, penetration testing, mobile platform security and all aspects of application and product security
  • Perform any other application security or product security related activities or tasks as needed or directed
  • Validate 3rd party external pen-test and crowd-sourced application security findings and work with our appsec team to triage those across to our engineering teams.

Basic Qualifications

  • Hold a pen-test certification such as Offensive Security Certified Professional (OSCP) or CEH, OSWE, OSCE, GPEN, GMOB, GWAPT, GXPN, and/or willing to work towards ultimately obtaining one as part of your career path
  • 3-5 years of relevant engineering or security assessment experience
  • Possess a broad knowledge of attack vectors, exploits and mitigations that work at scale or may be linked together for chained attacks
  • Experience with Java, Go, Python or Node.js (bonus points for more than one).
  • Experience with assessing with Cloud-native services, service meshes, and Kubernetes-platform based micro-services
  • Experience with assessment of mobile-based applications (not just web/UI)
  • Be able to apply unconventional thinking and problem-solve on the boundary of your knowledge base, learning new technologies or languages as needed to complete pen-test tasks
  • Be able to think both offensively (like a hacker) and defensively (evaluating product security and design)
  • Ability to create written work product, detailed technical findings documents, and pen-test reports

Preferred Qualifications

  • You have great interpersonal skills, deep technical ability, and a history of successful execution in the assessments industry. If you enjoy discussing anything from procedural linking tables in kernels to remote code execution in JVMs, then we want you on the team.
  • Familiarity with industry-standard threat modeling, risk modeling and vulnerability classification
  • Experience with pre-assessment architectural and API analysis to scope and prepare white-box and grey-box assessments
  • Experience working with in-house engineering organizations, S-SDLC/CICD software lifecycle and QA processes
