Endpoint Security Engineer

The Role

As a Security Engineer, you will play a dual role in securing Moderna’s hybrid infrastructure and strengthening our endpoint security capabilities. This position blends strategic architecture responsibilities with operational expertise in endpoint protection and incident response.

You will lead security risk assessments across our infrastructure, architect resilient networks and applications, and manage the deployment and effectiveness of endpoint detection and response (EDR) platforms. You will also be a critical part of our frontline response team—investigating endpoint-based threats, performing forensic analysis, and collaborating closely with the SOC and engineering teams to remediate incidents and enhance detection capabilities.

This role is ideal for a hands-on security expert who thrives in a fast-paced environment, balancing strategic security design with detailed forensic work and real-world threat mitigation.

Here’s What You’ll Do

• Manage and optimize endpoint security operations (e.g., CrowdStrike EDR), including agent deployment, coverage, and tuning.
• Respond to endpoint-related incidents, perform forensic investigations, and coordinate remediation.
• Conduct log analysis using SIEM tools, build dashboards, and generate alerts to improve threat visibility.
• Perform deep malware and file analysis to trace compromise vectors and prevent recurrence.
• Support purple team exercises to validate detection and response capabilities.
• Automate operational workflows using Python or similar scripting languages to streamline response processes.
• Tune detections in collaboration with the SOC to enhance coverage across the MITRE ATT&CK framework.
• Identify and remediate endpoint misconfigurations and vulnerabilities.
• Stay current on emerging threats, adversary tactics, and endpoint evasion techniques.
• Share threat intel with stakeholders and drive continuous improvement of endpoint defenses.
• Participate in change management and cross-functional security projects.

Basic Qualifications

Here’s What You’ll Bring to the Table:

• 5+ years of experience in cybersecurity, including hands-on experience in security architecture and endpoint threat response.
• Deep understanding of TCP/IP, network protocols, and endpoint operating systems (Windows, macOS, Linux).
• Hands-on experience with endpoint security tools (e.g., CrowdStrike, SentinelOne) and forensic toolkits.
• Experience analyzing and responding to malware, phishing, and lateral movement techniques.
• Familiarity with SIEM platforms and cloud logging (e.g., Splunk, Sentinel, Chronicle).
• Knowledge of AWS/Azure/GCP cloud security configurations and common misconfigurations.
• Ability to script or automate (e.g., Python, PowerShell) for repeatable response tasks.
• Experience conducting or supporting purple team exercises.

Here's What You'll Need

Preferred Qualifications

• Strong communication and documentation skills. Able to present findings clearly to both technical and executive audiences.
• Comfortable operating independently and taking initiative in high-stakes investigations.
