We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, Mongo

We are looking for an experienced Staff Engineer for our SRE, Infra Sec team
, to guide the security of our cloud-based infrastructure. As a Staff SRE
, you will be very hands-on technically while also mentoring a small team of SREs.

The Infra Sec team collaborates closely with other engineering teams to ensure that our infrastructure adheres to the highest security standards. They build essential security infrastructure and implement controls that reinforce the platform’s security posture.

This is an SRE team, which means you can expect a highly hands-on approach, tackling the technical challenges of implementing large scale solutions. This team is deeply involved in the technical aspects of security and the nuances of its actual implementation.

Responsibilities:
  • Cloud Security Design and Implementation: Help lead the design and deployment of security solutions for cloud platforms (AWS, Azure, GCP), including network and compute security, identity management, and cloud security posture management (CSPM).
  • Automation and Monitoring: Build automated solutions for real-time security monitoring, logging, and alerting in cloud environments. Leverage native cloud services and third-party tools for runtime security monitoring and anomaly detection.
  • Security Tooling: Evaluate, implement, and manage cloud-native security tools and platforms for endpoint security, identity management (IAM), and CSPM.
    • Qualifications:
  • Experience: 7+ years of experience in SRE, infrastructure engineering or similar role, with a strong focus on security work, with ideally 2+ years in a senior or staff engineering role.
  • Security Mindset: A comprehensive understanding of all facets of cloud environment security, spanning from foundational OS networking layers to cloud provider configurations. Proven experience in leading projects within security-focused areas, such as runtime scanning, security observability, CSPM, and more. Strong experience with at least one cloud platform (AWS, Azure, GCP), including expertise in IAM, VPC networking, security groups, and cloud security tools (e.g., Guard Duty, Security Hub, Cloud Trail).
  • Coding/Automation: Proficiency in at least one programming language (we use Golang but are language agnostic when it comes to hiring) and experience with infrastructure-as-code tools (Terraform, Cloud Formation, Ansible) to automate security configurations and processes.
  • Linux and Networking: Understanding of the underlying Linux and networking concepts, including low-level fundamentals, and how they work together in complex systems.
  • Communication and Leadership

    Skills:

     Strong ability to explain complex security concepts to both technical and non-technical teams. Ability to lead a small technical team and ensure success both meeting the team goals as well as personal growth for all team members.

    • To drive the personal growth and business impact of our employees, we’re committed to developing a supportive and enriching culture for everyone. From employee affinity groups, to fertility assistance and a generous parental leave policy, we value our employees’ wellbeing and want to support them along every step of their professional and personal journeys.
