Security at Compass International Holdings

The Security organization protects one of the largest and most complex real estate technology estates in the industry. We are hands-on engineers who build security as a service: secure-by-design tooling, automated guardrails, and trusted partnership with Engineering, rather than gatekeeping. As a Staff Security Engineer, you are empowered to directly drive technical security results and shaping the roadmaps that our engineering teams adopt and build against.

What You Will Do

• Automate & Scale Application Security: Build, enhance, and support automated application security testing frameworks and tooling to seamlessly integrate security into continuous integration and delivery (CI/CD) pipelines.
• Drive Secure-by-Design Architectures: Partner closely with engineering teams to evaluate solution architectures and codebases, providing technical feedback that embeds secure-by-design principles from the start.
• Serve as a Trusted Security Advisor: Act as a key resource and subject matter expert for product and engineering teams, offering security guidance and risk evaluations for new product features, development processes, tooling, and services.
• Evangelize Product Security: Advocate for secure-by-design approaches across the organizations helping to mature the overall security culture.
• Cultivate Collaboration: Build strong, collaborative relationships across the Product and Engineering organization to help product teams efficiently achieve their delivery goals without compromising on security.
• Secure & Accelerate with AI: Drive the adoption of AI-powered security capabilities (e.g., code/IaC scanning copilots and automated triage) to foster operational efficiencies, while establishing a AI Security Posture Management (AI-SPM) frameworks and secure-by-design standards needed to safely integrate AI into CIH products and protect enterprise data assets from emerging threats (such as prompt injection, model/data exfiltration, and unsanctioned "shadow AI" usage).
• Continuous Innovation: Stay ahead of industry trends, embracing and adopting new technologies to ensure security capabilities keep pace with evolving business and engineering objectives.

Who You Are

• Strategic Collaborator: You thrive in Agile and DevOps environments, viewing security as an enabler of engineering velocity rather than a bottleneck.
• Technical Leader & Advocate: You are passionate about mentoring others and can articulately champion security concepts to both deeply technical engineers and business stakeholders.
• Analytical Problem Solver: You possess exceptional troubleshooting skills and the logical capacity to diagnose complex architectural and pipeline security challenges.
• Self-Driven Achiever: You are highly self-motivated, with the organizational and time-management skills required to manage multiple complex initiatives simultaneously.

Minimum Qualifications

• Bachelor's degree in Computer Science, a related technical field, or equivalent practical work experience.
• Minimum of three (3) years of experience across the following areas:
• Administering and configuring automated pipeline tools (CI/CD).
• Administering and tuning application security testing tools (e.g., SAST, DAST, or SCA).
• Automation scripting using Python or Bash.
• Product development using Python, JavaScript, TypeScript, Golang, or Java.
• Performing security code reviews for solutions built in Python, JavaScript, TypeScript, Golang, or Java.
• Participating in security-focused reviews for both vendor and custom business solutions.
• Hands-on experience with Infrastructure as Code (IaC) tools (e.g., Terraform) to provision secure, reproducible infrastructure.
• Practical experience working with AWS services, aligning both product solution delivery and security objectives.
• Hands-on experience using Artificial Intelligence (AI) to assist with product security processes to drive team and operational efficiencies.

Nice to Have 

• Relevant industry certifications (e.g., CEH, CISSP, CSSLP, GIAC, or cloud security certifications) are a strong plus.
• Direct experience working within high-performing DevOps and Agile cultures.
• Experience with Layer 7 security controls (e.g., Web Application Firewalls (WAF), API Gateways, OAuth2/OIDC implementation, and rate limiting).
• Experience driving secure-by-design practices across multi-cloud strategies (e.g., AWS, Azure, GCP).
• Experience reviewing and assessing the use of AI technologies within both vendor-provided and custom-developed business solutions.
• Experience operating in a publicly traded company, including familiarity with SOX-adjacent control environments and audit processes.
• Experience securing environments through a merger, acquisition, or major infrastructure consolidation.
