Who is Flock?

Every community deserves to be safe, it’s a fundamental right. Our mission is simple - to build technology that reduces crime and protects privacy. Flock partners with cities, businesses, schools, and neighborhoods to help protect where people live, work, and play. Last year, Flock technology supported over 1 million criminal investigations. We've also helped solve approximately 20% of reported crimes in areas where we're deployed, and have played a role in locating more than 10,000 missing people.

We are a high-performance team united by urgency, ownership, and a shared commitment to meaningful impact. The work is fast-paced and the expectations are high. We push beyond perceived limits, support each other, and hold ourselves accountable to delivering results that matter.

With over $1B in funding and an $8.3B valuation, we are scaling with intention and investing in the people who will help us build what others said could not be done. At Flock, you will find the opportunity to grow quickly, take on real responsibility, and contribute to something bigger than yourself.

The Opportunity

We are looking for a Senior Adversary Pursuit Engineer. As someone with over 5 years of cybersecurity experience, at least 3 of those years in the trenches focused on DFIR/Threat Hunts, you will focus on developing and executing functions within Flock’s Adversary Pursuit program. You will help architect and execute threat hunts, technical cybersecurity exercises, and tactical threat intelligence collection looking for opportunities to improve these areas. You’ll work closely with our Offensive Security team to ensure a high level of efficacy in our ability to detect threats, and assist the Security Operations team with improvements to our response capabilities.

This is a critical role that will be responsible for developing new methods to search and detect threats across a rapidly scaling, high-value public-private safety network. You will assist with defining and executing hunts, determining and prioritizing visibility and detection gaps, and when necessary, assisting with response operations across thousands of deployed hardware devices, extensive cloud infrastructure, and core business applications. You will help with the creation of technical exercises against Flock’s full technology stack (hardware, software, cloud, network) to help increase preparedness and readiness. This role reports to the Director, Incident Response and Adversary Pursuit.

Success in this role will be measured by the development and execution of our threat hunt capabilities, ability and effectiveness to detect prioritized threats, and improved readiness to respond (through metrics such as MTTD).

The Skillset

• Leadership & Management:

  • Mold the long-term threat hunting roadmap, including strategy, data ingestion requirements, and coverage metrics.

  • Help design, execute, and see complex threat hunting campaigns through to completion, taking ownership of specific threat verticals (e.g., cloud environments, specific APT groups).

  • Serve as a technical mentor for junior and mid-level engineers. Review their technical work, provide constructive feedback on methodologies, and elevate the team's overall technical baseline.

• Technical Expertise:

  • Extensive technical expertise in performing DFIR and adversary threat hunts, across diverse environments (corporate systems, cloud - AWS/GCP/Azure, and operational technology networks).

  • Experience with performing DFIR on Android IoT devices.

  • Deep experience utilizing enterprise security tooling (SIEM, EDR, etc.) as well as developing proprietary tools/scripts to scale the team’s capabilities.

  • Experience utilizing sandboxing technology to aid in the analysis of suspicious binaries and scripts; hands-on reverse engineering experience a plus.

  • Hands on work with integrating security automation tools (Torq, Tines, SIEM native, etc.) and AI tooling (LLMs, agentic workflows) to accelerate security operations

  • Map findings to the MITRE ATT&CK framework to identify coverage gaps and improve detection posture.

  • Well versed in using cyber threat intelligence to update requirements, prioritize collection sources and integrate technical TTPs to inform and prioritize hunts.

  • Create and tune high-fidelity detection rules (e.g., Splunk SPL, YARA, Sigma) based on hunt findings to prevent future recurrence.

  • Assist with the development of technical table top exercises, ensuring scenario applicability to the organization’s risk profile and align to real world cyber events.

• Operational & Collaboration Skills:

  • Collaborate with Cybersecurity, Engineering, and Product teams to help plan, and execute threat hunts, providing detailed findings and data backed recommendations for cybersecurity and architectural improvements.

  • Work closely with the Offensive Security team to help perform regular testing and validation of custom detection rules.

  • Serve as a Tier 3 escalation point for SOC analysts; perform deep-dive root cause analysis on complex security incidents.
