    Description

    You will not see any vendor names in the responsibilities listed below. We are more interested in aptitude and attitude, than specific OS experience. Let us know your history, but of more interest is your grasp of technical concepts, not specific user interfaces. We want team members who will take ownership of issues and drive them to resolution, not simply perform tasks as assigned. You will act as a subject matter expert (SME) on behalf of our customers (other business units within 7-Eleven), to ensure their projects and deployments succeed with appropriate security posture, in a timely manner. You must have a passion for learning new technologies, not simply working with what you already know. You will be provided with the tools to produce your own career success, but you must seize them and create that success. You will be challenged in a fast-paced environment, but success in handling these challenges will not go unnoticed or unrewarded.

    Responsibilities:

    • You will be responsible for all aspects of Network Security within 7-Eleven. You will be a SME in some domains (not all), but are expected to use advanced professional knowledge of security concepts and company objectives to resolve complex issues in creative and effective ways, in all of the following domains. As a senior engineer, you are expected to do these things without technical direction and with only occasional guidance:
    • Firewalls and network filters, in both Enterprise, Stores, and cloud networks
    • Intrusion Prevention policies
    • Site-to-site and remote-access VPN connectivity
    • Network Access Control
    • Authentication, Authorization and Accounting (to include multi-factor authentication)
    • Web access proxy servers and URL filtering
    • PKI and certificate issuance and management
    • DNS Security
    • Threat research, vulnerability remediation, and creation of compensating controls
    • Network Security policy creation, exception documentation and approval
    • Management of multi-factor authentication tokens
    • Create your professional development and training plan for approval by manager.
    • Prioritize taskings and projects assigned based on importance to accomplishment of business objectives. Determine methods and procedures on new assignments. Assist junior teammates with maintaining proper prioritization.
    • Solve complex issues where analysis of situations and data require in-depth evaluation of variable factors. Provide escalation support and technical guidance to teammates.
    • Lead projects assigned to you, in effort to advance partnership opportunities between Network Security team and other business areas. Determine appropriate methods and procedures on new assignments and occasionally assist with coordinating activities of junior teammates.
    • Work with team lead/manager to define network security requirements for current and future state end-to-end architectures and platforms to advance security controls and the security posture of the business.
    • Collaborate with development and engineering teams to prioritize security risks, provide mitigation or remediation recommendations, and implement compensating controls.
    • Perform network security architecture and third-party risk management reviews.
    • Perform or lead teammates in performing network security platform testing, vulnerability remediation, and operating system hardening to reduce attack surface.
    • Perform or lead teammates in performing proof-of-concept testing for network security solutions under consideration for purchase and implementation.
    • Provide team lead/manager with updates and metrics on effectiveness of network security controls.
    • Develop and maintain network security policies, standards, processes and workflows
    • Assist team lead/manager with identifying network security products and technologies that can enhance 7-Eleven's mission by providing appropriate protection for all data on the network, or sent or received to/from various public or private clouds, or the Internet at large.

    Qualifications:

    Education/Experience

    • Bachelor's degree in related field, Master's preferred, or equivalent experience
    • 8 years of related experience with Bachelor's, 6 years with Master's

    Certification/Licenses

    • Must have: At least one non-entry-level vendor certification in the Network Security arena (Palo Alto PCNSE preferred, Cisco CCNP Security, Juniper JNCIP-SEC, etc.) or equivalent experience
    • Preferred: At least one non-entry-level vendor-neutral certification in the Information Security arena (CISSP, CISM, GISP, etc.)
