Overview

We are looking for a senior security engineer with a deep passion for cloud infrastructure and zero trust architecture to join our security team. This role is ideal for experienced security professionals who excel in security at scale, focusing on cloud and workload security, identity management, and modern containerized application architectures. In this role, you’ll be responsible for leveling up the security posture of our smaller subsidiaries and business units. You’ll be the first point of contact for Instacart’s in-house startups, working on new Instacart ventures like smart shopping carts, pricing intelligence, and in-store technologies that will radically change the way people shop. This role provides the fast-paced environment of a startup while still being part of a larger security organization. With us, you’ll embark on a journey to further secure Instacart’s platform and products, leveraging automation and creativity to maximize your impact on our company’s security posture.

Our goal is to run the world's most trusted and secure grocery technology platform. The infrastructure security function within the Instacart security team works with stakeholders in product development, infrastructure, IT, finance, legal, and other cross-functional departments to help design and implement effective solutions and controls to protect our most valuable assets.

About the Team

The security team at Instacart is responsible for ensuring the security and privacy of Instacart’s suite of products and the company as a whole. We believe that with the right mixture of tools and engineering prowess, we can secure our most important assets without negatively impacting productivity.

In this role, you will continue to build out our next generation of security controls in direct partnership with our subsidiaries and emerging products, ensuring they’re both user-friendly and firmly secure. As part of this fast-moving team, you will have the chance to work on innovative cloud security controls, web application security architectures, and our zero trust / cloud identity initiatives. This role will provide you opportunities for continuous learning, mentorship, and personal growth in a culture that values collaboration and innovation.

About the Job

  • Implement and maintain scalable security solutions, primarily in AWS, but also in our smaller footprints in Google Cloud Platform and Azure.
  • Advise on common best practices for secure application design and architecture.
  • Continue to enhance our cloud security posture by improving and maintaining best-in-class open-source and commercially-available solutions across our applications and infrastructure.
  • Collaborate with cross-functional teams, including IT, security platform engineering, and infrastructure, to further remediate vulnerabilities, integrate zero trust principles, and advance our IAM practices within our in-house startups.
  • Engage in hands-on problem-solving, always seeking better ways to control and monitor our growing ecosystem while not increasing our alerting burden and minimizing the need for manual interventions.
  • Participate in on-call rotations to support critical operations and respond promptly to security incidents.
  • Share knowledge and mentor other team members, promoting a culture of continuous learning and improvement.
