## Description

We are seeking a Secure Developer to design and implement advanced endpoint and runtime protection controls for critical software environments. This role focuses on Linux hardening, container security, and low-level system telemetry, helping reduce risk across core application and infrastructure layers.

You will work at the intersection of systems engineering, security, and DevSecOps, building robust protections directly into Ubuntu hosts and Docker environments, and integrating security telemetry into early-stage SIEM and detection pipelines.

This is a hands-on engineering role requiring deep understanding of Linux internals, container runtimes, and security hardening standards., * Harden Ubuntu Linux hosts at kernel and OS level using:

 * namespaces
 * AppArmor
 * Implement and maintain auditd rules, syscall-level logging, and host/container telemetry for detection, monitoring, and forensic analysis
 * Apply and enforce CIS Benchmarks (Level 2) for:
 * Docker containers and runtime environments
 * Hardened base image standards and secure configuration baselines
 * Secure Docker runtime environments through:
 * least-privilege execution models
 * container isolation strategies
 * image provenance and signing
 * Integrate host and container logs into prototype SIEM pipelines, enabling correlation and early threat detection
 * Automate security controls, hardening processes, and compliance checks using:
 * scripting (Python / Bash)
