We break the mold; the traditional lines between network engineering, system administration, and application development are blurring with today's abstracted environments, and our ENEs apply their expertise in each of these to make advanced technology work.

We're looking for a top performer who likes to solve problems, leveraging technology in creative ways to accomplish goals, and sharing knowledge with others. You are cool under pressure, a master of carefully disentangling and solving the most complex of mysteries, and always looking for opportunities to improve the way things work. When faced with the unknown, an ENE's first response is "Challenge Accepted."

• Provide Tier-3 support for F5 Global Services.

• Take ownership of issues and drive them to resolution.

• Handle technical issues of any complexity with minimal supervision.

• Appropriately manage time and customer issues based on issue severity and business needs.

• Develop creative solutions to problems and prove them out in a lab environment.

• Solve the unsolvable. Thrive on attacking complex technical challenges that can span the OSI model into application behavior and software/hardware interactions.

• Direct interaction with Product Development group on behalf of all external organizations and customers.

• Work with Product Development and Product Management to ensure products are implemented in ways that meet customer requirements.

• Participate in knowledge-share via documentation creation, training, and mentoring.

• ENEs will spend about 70% working on escalations (customer issues), and 30% working on other departmental projects.
