The Problem

As Flock expands its video capabilities, delivering custom video management software with extremely low latency is critical to giving customers real-time situational awareness. Building interactive live video streams and intuitive web interfaces allows agencies and security teams to respond swiftly when timing matters. You will lead frontend architecture, build responsive web applications, and engineer high-definition live video interfaces on our Cloud Video team.

What You'll Own
  • Architect and execute frontend web applications using React, TypeScript, and Node.js for Flock's custom Video Management Software.

  • Build low-latency, interactive live video playback features and real-time alert dashboards across client platforms.

  • Implement performant UI optimizations to ensure smooth, responsive user experiences across diverse devices and browsers.

  • Design and integrate clean APIs connecting web clients to cloud video microservices and storage platforms.

  • Collaborate cross-functionally with product, design, and backend engineering teams to deliver user-centric video capabilities.

What This Role is Not
  • This isn't a backend-only or infrastructure engineering role, you will maintain fullstack context but your primary focus is frontend web execution.

  • This is not a role requiring prior specialized video domain expertise, we will teach you the video domain as long as you possess deep frontend application capability.

  • This isn't a static UI design job, you will write production-grade web code, optimize streaming performance, and ship features into high-traffic live environments.

What You Bring
  • Demonstrated frontend development experience with deep mastery of React, TypeScript, and Node.js web services.

  • Capability to diagnose and implement UI performance optimizations across data-heavy, real-time web applications.

  • Practical understanding of web API design and client-server communication.

  • Working familiarity with cloud tooling and containerized services using AWS, Docker, or Kubernetes.

  • Resourceful problem-solving mindset with a commitment to continuous learning in fast-paced software environments.

Compensation

In this role, you'll receive a starting salary between $160,000 and $190,000 as well as Flock Stock Options. Base salary is determined by job-related experience, education/training, as well as market indicators. Your recruiter will discuss this in depth with you during our first chat.

Why Flock

Every community deserves to be safe. Flock builds the technology that makes that real: last year we supported over 1 million criminal investigations and helped locate more than 10,000 missing people. We're 1,700 people building the impossible with over $1B in funding, and the expectations are high on purpose. If you want a role where the stakes are real and the pace matches, this is it.

Some problems get solved faster in the same room, so we prioritize candidates in Atlanta and Boston. Hub-based roles mean real in-person time with your coworkers. Remote roles exist, and when a posting is open to remote work, it says so.

Building the impossible takes every kind of mind. Flock is an equal opportunity employer, and we know the best solutions come from diverse perspectives, experiences, and skills working together with mutual respect. Everyone is welcome to apply. If you need assistance or an accommodation due to a disability, email [email protected]; your information stays confidential and is used only to arrange the right accommodation for your interviews.

On compensation: we pay fairly for the work. Base salary is determined by job-related experience, education, training, and market indicators. The range in this posting covers base salary only and doesn't include equity, sales bonus plans where applicable, or benefits. The range may be adjusted over time, and this posting may span more than one career level.

One last thing: all legitimate communication from Flock comes from an email ending in @flocksafety.com or [email protected]. We never make offers through messaging apps or third parties, and we never request payment or sensitive personal information during hiring. If you encounter suspicious outreach about a Flock role, report it to [email protected].
