Rumble Cloud is seeking a Senior Platform Engineer (Security) to operate, secure, and harden the infrastructure powering their public cloud. This role involves applying security hardening across Linux systems and the cloud control plane, tracking vulnerabilities, and supporting audits. The position offers significant impact and technical depth for those who enjoy hardening Linux at scale and working with control frameworks.

Responsibilities

Assess, implement, and maintain security hardening across Linux hosts, hypervisors, and the cloud control plane using automated baselines.
Track and remediate vulnerabilities at the infrastructure layer, including operating systems and platform components.
Coordinate with the DevSecOps Engineer on application- and pipeline-layer remediation.
Serve as a primary technical contributor to internal and external audits, including evidence collection and control narratives.
Operate and improve core platform services on Linux infrastructure, contributing to automation, capacity planning, incident response, and reliability engineering.
Help design logging, monitoring, and alerting that support both operational and security use cases.
Document hardening baselines, security controls, and operational procedures clearly.

Requirements

Strong Linux systems engineering background (systemd, networking, storage, package management) on major Linux distributions.
Hands-on experience applying security hardening standards such as CIS Benchmarks, STIGs, or equivalent at production scale.
Solid understanding of vulnerability management (CVSS scoring, risk-based prioritization) and Linux security controls (SELinux or AppArmor, auditd, PAM, host firewalling).
Experience with infrastructure automation using Ansible, Terraform, and scripting in Bash and/or Python.
Experience supporting compliance or audit activities, including evidence collection, control documentation, and working directly with auditors or security teams.
