Senior Security Engineer

Miradero is a specialized MSSP delivering high-fidelity security and compliance services to regulated SMBs (Healthcare/Financial) in Southern California. We are building a lean, high-density operation that prioritizes technical precision over corporate overhead. We are currently in the launch phase and seeking a founding operational leader to build our SOC from the ground up.

About the Role

We are looking for a Toolsmith. You will be the primary builder of our technical infrastructure, responsible for transforming security requirements into scalable code. You are not a “tool operator”; you are a platform engineer who uses security tools as components in a larger, automated system.

You will partner with the CTO to implement our proprietary AI layer and work alongside the SOC Manager to ensure that detection logic is operationalized without friction.

What You’ll Do

• Platform Engineering: Architect and build the multi-tenant telemetry pipeline. Implement “Detection-as-Code” using GitHub/GitLab for version control and CI/CD deployment of detection logic.
• Tooling Orchestration: Own the deep technical configuration and integration of CrowdStrike Falcon (EDR) and ArmorPoint (XDR/SIEM). You will be responsible for the “plumbing” that ensures high-signal telemetry flows from endpoint to analyst.
• Python Development: Write production-grade Python scripts to automate repetitive SOC tasks, build custom API integrations between our security stack and PSA/Documentation tools, and develop internal tooling.
• AI Implementation: Co-lead the engineering of our private AI layer. This includes building RAG (Retrieval-Augmented Generation) pipelines and developing LLM-based classifiers to automate triage and summary generation.
• Detection Authoring: Act as the senior authority for detection content across CrowdStrike (CQL/LogScale) and ArmorPoint, ensuring rules are tuned to minimize false positives.
• Technical Pre-Sales: Serve as the technical authority on standard client engagements, scoping the technical requirements for pilot deployments and ensuring architectural sanity.
• Escalation Engineering: Act as the final technical stop for complex root-cause analysis and deep-dive investigations that exceed the SOC’s standard playbooks.

• 7+ years in Security Engineering, Detection Engineering, or Platform Architecture.
• Coding Proficiency: Strong Python skills are non-negotiable. You must be able to write clean, maintainable code for automation and API integration.
• DevOps Mindset: Fluency in Git (GitHub/GitLab). Experience with CI/CD pipelines and treating infrastructure/detections as code.
• Tooling Expertise: Deep, hands-on experience with CrowdStrike Falcon and ArmorPoint (or equivalent enterprise EDR/XDR platforms).
• Infrastructure Knowledge: Strong understanding of cloud telemetry (AWS, Azure, GCP) and identity frameworks (Entra ID/Okta).
• Security Frameworks: MITRE ATT&CK fluency and experience translating those tactics into actual detection logic.

Pulled from the full job description

• Health insurance
• Paid time off
• Vision insurance
• Dental insurance, The Right Personality:
• Builder Mentality: You prefer building a tool that solves a problem over manually solving the problem ten times.
• Low Ego / High Output: You are comfortable being mentored by a CTO and operating as a peer to the SOC Manager.
• Precision-Driven: You value documentation and architectural clarity over “quick fixes.”

Why Miradero Cybersecurity

• Founding Influence: You are the first engineering hire. Your architectural decisions will define the company’s technical trajectory.
• The AI Moat: You will lead the implementation of a private, local AI stack-building a technical advantage that separates us from legacy MSSPs.
• Equity & Growth: Employee equity options in a lean, well-funded startup with a clear path to technical leadership.
• Operational Autonomy: High trust, low micromanagement environment.
