Movable Ink is hiring a Security Detection Engineer to strengthen our security monitoring and detection capabilities. To succeed in this role, you'll combine deep technical curiosity with a methodical approach to threat detection, helping protect our platform and the hundreds of enterprise customers who depend on it. This is a hands-on opportunity to own and evolve our detection engineering practice, working closely with our Security Engineering team. You'll play a critical role in ensuring we can identify and respond to security threats quickly—whether they target our employees, infrastructure, or cloud environments.

Responsibilities:

• Build, tune, and maintain detection rules and alerts in Splunk to identify security threats, suspicious activity, and policy violations

• Reduce alert fatigue by continuously improving detection logic to minimize false positives while maintaining coverage

• Monitor and develop detections for cloud security events across AWS and GCP using our CSPM tooling (Prisma Cloud)

• Collaborate with the Security team to develop detection strategies based on threat intelligence and the MITRE ATT&CK framework

• Investigate alerts and escalate confirmed incidents according to our incident response procedures

• Set up and configure automation scripts and tooling for alert triage, ticket creation, and incident workflows

• Create dashboards and reports to provide visibility into security posture and detection effectiveness

• Document detection logic, runbooks, and response procedures

• Support EDR (CrowdStrike) monitoring and investigate endpoint-related alerts

• Identify opportunities to use Splunk for operational and product monitoring beyond pure security use cases

Qualifications:

• 2+ years of experience in a security operations, detection engineering, or SIEM-focused role

• Hands-on experience writing and tuning SPL queries in Splunk

• Familiarity with common attack techniques and the MITRE ATT&CK framework

• Experience with cloud platforms (AWS or GCP) and understanding of cloud-specific threats

• Exposure to EDR platforms (CrowdStrike preferred) and CSPM tools

• Understanding of log sources such as Okta, Google Workspace, endpoint logs, and network traffic

• Strong analytical and troubleshooting skills with attention to detail

• Clear written and verbal communication skills; ability to document findings and escalate effectively

• Self-motivated and comfortable working autonomously with a distributed team
