Job Description

We create and optimize solutions for a rapidly growing mature Adtech business on a global scale. We work with distributed infrastructure, petabytes of data, and billions of transactions with no limitations on your creativity. You don’t have to always wait for an architect or manager to tell you what to work-on, you will decide your priorities! Our tech hubs are in Redwood City and Pune.

Position Summary:

Within the Adtech environment, you have a deep understanding of the complex nature of security spanning infrastructure, applications and IT. You feel comfortable understanding security in the context of infrastructure, applications (java, open source tools). Does not hesitate digging into code to understand the subtle and obscure problems that can arise due to security vulnerabilities in the environment. You work with people, technical and non-technical alike, to understand security posture needed to help them understand, implement changes to address them. You're a company resource, providing best practices, guidelines, and feedback around security. You have your finger on the pulse of security across the Ad platform internally as well as from what happens externally. 

You have a cool head under pressure. When a technical fire occurs, you understand that putting it out should always avoid collateral damage. When you cause a fire (as everyone inevitably does), you take responsibility for it and work with the team to figure out the right way to put that fire out. You believe blaming is a waste of time: when something goes wrong, you figure out why it happened and how to prevent it from happening again in the future. Better yet, you look for how things went right in the first place and improve upon those. 

About you:
As a member of security team, you seek out feedback on your findings, designs and ideas and provide the same to others. You constantly ask 'What am I missing?' and 'How will this NOT work?' You don't shy away from what you don't know; you readily admit that you don't know everything, and use every resource available within and outside the company to learn what you need to know.
