DigiCert is hiring a Backend Engineer

Responsibilities

  • As part of the engineering team, you’ll work alongside industry-leading cryptographers, AI/ML innovators, cloud infrastructure experts, and security engineers who are defining the future of secure digital interactions.
  • Architect and build the Identity Foundation: Design and own a cryptographically secure identity system that serves as the "source of truth" for all AI workloads, ensuring every agent has a verifiable and tamper-proof digital passport.
  • Build Runtime Enforcement: Develop high-performance systems to control agentic interactions in real-time. You will ensure that agents operate strictly within their authorized boundaries without introducing latency.
  • Define Governance Logic: Create the engines that translate complex human policies into machine-executable rules, controlling how agents access tools, databases, and LLMs.

  • Identity & Security Infrastructure: Hands-on experience with SPIFFE/SPIRE, PKI, and mTLS. You understand certificate lifecycle management, OIDC, and OAuth2 at a protocol level.
  • Cloud-Native Networking: Expert-level knowledge of Kubernetes (K8s) You have worked extensively with Envoy Proxy, Service Meshes (Istio/Linkerd), and Open Policy Agent (OPA).
  • Cloud & DevOps: Experience deploying and securing production workloads on AWS, GCP, or Azure. You are comfortable with Infrastructure as Code (Terraform)
  • You have a "bias for shipping" and are comfortable building CI/CD pipelines and observability stacks (Prometheus/Grafana) from scratch.
