About the role

Role Overview

Join Flock as a Senior Software Engineer (Frontend) for The Problem Search, a critical customer-facing tool used to follow leads, identify vehicles, and resolve cases faster. You’ll lead frontend web architecture and optimize high-traffic search experiences while partnering across product, design, and backend teams.

You Will Own

  • Lead the architectural evolution and frontend execution for core Search features across a React, TypeScript, and Node web stack
  • Translate user research and design mocks into production-grade, performant user experiences
  • Build map-based data visualizations and geospatial interfaces (high-density location data)
  • Champion frontend engineering standards, including thorough code reviews and mentoring across the Search team
  • Monitor and optimize client-side performance, including state management and data retrieval for data-heavy web apps

What This Role Is Not

  • Not backend-heavy or infrastructure-focused; the emphasis is frontend architecture and UX
  • Not a design-only/prototyping role; you will write and ship production code
  • Not an isolated contribution role; you’ll participate in customer calls and team retros, and mentor peers

What You Bring

  • Mastery of modern frontend web technologies and application design patterns using React and TypeScript
  • Experience building map-based visualizations using Mapbox or Google Maps API
  • Fullstack working context with Node.js services and API design concepts such as REST, GraphQL, or gRPC
  • Understanding of backend interaction patterns and relational databases like PostgreSQL
  • Resourceful problem-solving in ambiguous environments and a mindset of continuous learning

Nice-to-Haves

  • Familiarity with AWS managed services
  • Frontend performance optimization experience for high-traffic applications

Location / Work Model

  • Hub-based roles prioritized in Atlanta and Boston with real in-person time
  • Remote roles may be available when explicitly stated
