Senior Security Engineer — Cloud Security (Platform Engineering, Kubernetes & Identity)
Pager Duty is seeking a Senior Security Engineer to join our Cloud Security team, part of Security Engineering within the CTO organization. This is a preventive, platform-focused role for a strong engineer: you'll build and operate security-focused systems at scale to protect Pager Duty's multi-account AWS environment and the Kubernetes platforms running on it, with deep responsibility across container security and identity & access management (and, ideally, cryptography and key management).

You'll harden the platform, design least-privilege identity and workload identity, and — because we're a lean team without a dedicated SOC — you'll shape detection strategy for the domains you own (Kubernetes and identity) and hunt during incidents. We lean hard into AI to move faster, so you'll both use and build agentic solutions to streamline how the team hardens, threat models, assesses risk, and operates.

You'll partner with 30+ engineering teams to unblock them securely, and since we own and operate what we build, your controls ship as code, get validated against real usage, and roll out without disrupting engineering — including across our FedRAMP footprint.
** This role will be require to work 2 days week from our Atlanta office
** What you'll do Harden Pager Duty's AWS and Kubernetes environments against CIS Benchmarks, DISA STIGs, and FedRAMP Moderate (Class

C) baselines across a multi-account, multi-org footprint — proving results through evidence, config-remediation tooling, and KPIs that track posture, identity, and encryption/PKI health so we know where we stand and where the gaps are.

Own Kubernetes and container security end to end — harden EKS clusters and the Istio service mesh against the CIS Kubernetes Benchmark, DISA Kubernetes STIG, and NSA/CISA Kubernetes hardening guidance, design and enforce Kubernetes RBAC and least-privilege workload identity (IRSA/pod identity), and drive controls for the container supply chain (image provenance, admission control, runtime policy).Build and operate security-focused platforms, services, and automation at scale — using Python/Go, Terraform, and Kubernetes policy-as-code — that reduce manual work and let 30+ engineering teams move quickly and safely.

Own PKI and encryption standards across the environment — certificate lifecycle and management, KMS-backed key management and rotation, TLS/mTLS (including within the Istio mesh), and encryption-at-rest and in-transit requirements — and define the standards other teams build against.

Design and roll out Service Control Policy (SCP) guardrails and least-privilege IAM/PAM across dozens of accounts and multiple orgs.

Lean into AI to unlock efficiency and velocity — consume agentic tooling in day-to-day work and build lightweight agentic solutions that streamline repetitive security work: posture triage, threat modeling, risk assessment, incident enrichment and investigation, compliance-evidence…
