Overview

FriendliAI is looking for an engineer to architect and build the security foundations of a multi-tenant serverless compute platform running on Kubernetes with hardened container isolation. As a Software Engineer, Platform Security, you will own the security design for both control plane and data plane, implement guardrails as code, and partner closely with Platform/SRE/Infra teams to ship a secure-by-default developer experience. This is a hands-on builder and architect role.

Key Responsibilities

  • Design and implement the security architecture for a Kubernetes-based, multi-tenant serverless platform.
  • Build guardrails as code using Terraform and Helm.
  • Establish network segmentation and service-mesh policy.
  • Develop secrets and key management patterns.
  • Implement runtime detections for containerized workloads.
  • Design and roll out IAM & workload identity management.
  • Threat model new features and changes to the overall platform.
  • Collaborate with engineering to debug production issues, lead post-incident hardening, and automate evidence for compliance controls.

Qualifications

  • 5+ years securing cloud-native platforms with a focus on distributed systems and multi-tenancy.
  • Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent.
  • Strong hands-on experience with AWS (IAM, VPC/networking, logging/monitoring, …) and Kubernetes/container security.
  • Proficiency with Terraform and Helm.
  • Experience building or operating runtime detections for containers/functions.
  • Strong technical background in backend systems, cloud infrastructure, or AI tooling.
  • Clear written and verbal communication; ability to translate pricing/business rules into robust systems.

Preferred Experience

  • Knative or similar serverless-on-K8s frameworks.
  • Container hardening and sandboxing.
  • Policy-as-code and admission policy design at scale.
  • eBPF-based observability, detections, and signal tuning.
  • Multi-cloud exposure and cross-cloud identity approaches.
  • Hands-on contributions to SOC 2 / HIPAA control automation and audit evidence pipelines.
  • A front-row seat to the AI infrastructure revolution.
  • Opportunity to work cross-functionally with top-tier engineers, product leaders, and go-to-market teams.
  • Competitive compensation.
  • Premium hardware and health support benefits.
  • A highly collaborative, fast-moving team where your impact is immediate and visible.
