Senior Security Analyst

Flock

About The Position

We are looking for a Senior Security Analyst to serve as a cornerstone of our Security Operations. At Flock, security is the foundation of the trust we build with the public. As someone with over 5 years of experience in the trenches of Security Operations or Incident Response, you will focus on defending the data that helps solve crimes and save lives. This is a "builder" role. You won’t just be monitoring dashboards; you will be responsible for maturing our detection pipeline, automating our response capabilities, and ensuring our rapidly scaling cloud infrastructure remains a fortress. You will sit at the intersection of engineering and operations, working to ensure that as Flock grows, our security posture doesn't just keep up—it leads the way. You will report to the Manager of Security Operations. Success in this role will be measured by your ability to reduce MTTR (Mean Time to Respond), the efficacy of your custom detection logic, and your success in automating manual security workflows to allow our team to scale.

Requirements

Over 5 years of experience in the trenches of Security Operations or Incident Response
Deep technical expertise in cloud security services across a multi-cloud environment – solid understanding of cloud-native security logging and identity management, as well as experience in responding to cloud infrastructure security alerts (compute, containers, serverless, networking).
Extensive experience building and tuning high-fidelity alerts in modern SIEMs (e.g., Panther, Snowflake, or Splunk) and EDR platforms (e.g., SentinelOne, Crowdstrike).
Strong proficiency in Python or Go to build "security-as-code" tools, automate repetitive SOC tasks, and integrate disparate security APIs.
