Senior Security Systems Engineer Required

Senior Security Systems Engineer – Security Control Plane / IAM / Cloud Security We are building a security platform focused on identity, continuous trust, risk-aware authorization, short-lived access, and verifiable security controls. We are looking for a senior hands-on Security Systems Engineer to join a small engineering team working on the architecture, integration, testing, and hardening of this platform. This is a technical engineering role—not a documentation or compliance-only position. What You Will Work On Security control-plane and Zero Trust architecture IAM, authentication, authorization and PAM Short-lived, revocable access / privilege mechanisms Identity and device trust relationships Endpoint/XDR security signal integrations Security event normalization and trust/risk context Kubernetes and cloud security Workload identity, mTLS and service-to-service security Security policy enforcement and deterministic authorization Security telemetry, event pipelines and observability Threat modeling, attack simulation and security testing Performance and reliability testing of security-critical services Designing secure failure and outage behavior Technologies Experience with several of the following is highly desirable: Microsoft Entra ID / Azure AD, Okta or other enterprise IAM PAM / JIT / privileged access Cortex XDR/XSIAM, Microsoft Defender or other EDR/XDR platforms WebAuthn / FIDO2 / passkeys SPIFFE/SPIRE and workload identity Kubernetes Docker Cilium / eBPF / Tetragon NATS / JetStream or similar event streaming ClickHouse or other high-volume security data platforms REST APIs, event-driven architecture and microservices PKI, certificates, mTLS and cryptographic signing Cloud platforms such as Azure, AWS or GCP Terraform / Infrastructure as Code Python, Go, Java, Node.js or similar backend technologies You do not need to have experience with every technology listed.
