Big tech impact, without the big tech ick.
The Role
This role sits at the intersection of cloud infrastructure and security. We are looking for an inquisitive, highly thorough engineer who analyzes complex systems across AWS, networking, client-server, and web layers to identify vulnerabilities and structural weaknesses.
We’re looking for someone who understands more than a single cloud tool, we need a problem solver with deep technical instincts and a relentless drive to investigate root causes. If you naturally question assumptions, pull threads until issues are fully resolved, and want to apply that rigor to infrastructure security, this role is for you.
You will partner with platform, software, and data engineering teams to integrate security directly into core infrastructure and development workflows.
How you will spend your time
Audit and advise on how to harden, and configure AWS infrastructure and core networking stack
Integrate automated security checks into CI/CD pipelines and infrastructure-as-code (Terraform)
Manage security posture across Kubernetes clusters and CrowdStrike CSPM environments
Conduct deep-dive investigations into security incidents and edge cases, delivering end-to-end remediation
Collaborate cross-functionally to influence architectural and security decisions early in design cycles
Develop automation to eliminate repetitive security tasks, leveraging AI tools where effective
Own key infrastructure security initiatives with mentorship from engineering leadership
About you
Proven background in infrastructure engineering across AWS and core networking principles
Demonstrated inquisitiveness and attention to detail — a track record of investigating unexpected behavior to complete root-cause resolution
Strong active interest in cloud security fundamentals and defensive engineering
High autonomy and ownership; able to drive complex technical tasks without requiring predefined playbooks
Clear technical communication skills to influence engineering teams across the organization
Practical coding experience (Python, Go, or similar) along with hands-on Terraform and CI/CD knowledge
Nice to have
Experience with CSPM tools (e.g., CrowdStrike) or enterprise identity management (Okta, Google Workspace, Kandji, Intune)
Working knowledge of Kubernetes administration and security practices
Background in systems administration or network security
Success looks like
You are recognized as a key technical resource for cloud infrastructure security across engineering
Our whole engineering team benefits from a greater understanding and appreciation of the benefits of security in our cloud platforms
Core AWS and Kubernetes environments are measurably hardened and automated
Manual security operations and toil are systematically reduced through custom automation and tool integration
We’re committed to building inclusive teams and cultivating a sense of belonging so our people can bring their whole authentic selves to work each day.
