Brain-computer interface expands new possibilities for life.
About the role
As our Security Engineer, Infrastructure, you'll secure the platform layer end-to-end including cloud infrastructure, Kubernetes, identity, networking, and the systems that AI runs on. This is a hands-on builder role. You'll write code, ship infrastructure, and work shoulder-to-shoulder with our infra team as a true engineering partner, not a reviewer. It's a high-ownership role for someone who wants to build secure-by-default infrastructure from first principles, and grow the function as the company scales.
What they're looking for
- Have 5+ years of experience in security engineering, infrastructure, or SRE with hands-on experience building or securing production systems at scale
- Are fluent in cloud security fundamentals (IAM, networking, KMS, secrets, isolation) across AWS, GCP, or Azure
- Have designed and implemented secure systems end-to-end not just reviewed them after the fact
- Have hands-on experience with Kubernetes, container security, and Linux systems
- Think in terms of threat models, trust boundaries, and failure modes and can translate that into concrete controls
- Enjoy building paved roads and guardrails using Infrastructure-as-Code (Terraform preferred) so the whole team moves faster safely
