The Zscaler Focal Support (FS) team is built around the proven concept of a small group (pod) of support engineers that are very technically competent and familiar with both the technology deployed by a customer and the people maintaining it. As a Focal Support Engineer you will earn the trust of your customers and deliver a superior support experience, being well positioned to respond faster and more effectively to any technical issues that might arise for customers under your care. A pod works in partnership with the assigned Technical Account Managers (TAMs) and account teams for a small number of customers to provide a  personalized, high touch and extremely knowledgeable response to technical questions and problems. As an FS engineer, you will know your customer's history and will understand why certain features are being used and avoid recommendations that don't work in their environment or align with their roadmap. Unlike a regular front line support engineer, an FS engineer's ratings will bias on team performance over individual performance. Of course, individual performance is still important and providing deliverables like team technical training, on-call coverage and high CSAT scores will be part of an individual's annual review process. However the performance of the team represents the most important metrics and each FS engineer contributes to this in a very meaningful way. The pod is focused on continuously building customer trust in our product for mission critical infrastructure. You will be a valuable member of a high performance team delivering technical solutions to some of the largest enterprises in the world!

  • You will be working closely with the same people at your assigned customers, good communication skills and an open and sharing attitude are essential! You are expected to keep you customers up to date regularly.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
