Job description

Active Firefighting & Triage: Rapidly isolate, reproduce, and resolve critical production and staging defects, with an emphasis on high-visibility demo issues and UI crashes.

Heavy UI Troubleshooting (80%): Debug complex client-side performance bottlenecks, state management issues, broken components, memory leaks, and DOM rendering delays in an enterprise Angular application.

API & Cloud Integration Debugging (20%): Inspect payload mismatches, authentication tokens, network timeouts, and middleware bottlenecks across RESTful APIs, Node.js services, and AWS infrastructure.

Demo & Release Readiness: Partner directly with product, QA, and sales engineering teams to ensure client-facing demo environments remain stable, performant, and zero-defect.

Root-Cause Analysis (RCA): Implement fast, surgical hotfixes to resolve immediate fires, followed by documented root-cause fixes to prevent recurring disruptions.

Requirements

Exceptional Debugging Skills: Advanced proficiency with Chrome DevTools (Network, Console, Performance profiler, Memory tab) to trace client-side bugs without waiting for backend teams.

Fast-Paced Firefighting Mindset: Demonstrated ability to remain composed under pressure, triage incoming incidents quickly, and push targeted hotfixes under tight timelines., Angular Mastery: 4+ years of deep, practical experience building and debugging complex web applications using modern Angular (v12+). Thorough understanding of RxJS, Observables, component lifecycle, ChangeDetection strategies, routing, and state management.

Node.js & REST APIs: Strong working knowledge of Node.js for diagnosing backend/middleware bottlenecks, analyzing server-side error logs, and fixing REST API payload/contract mismatches.

AWS Cloud Familiarity: Direct experience navigating AWS environments (CloudWatch logs, API Gateway, S3, Lambda, EC2) to trace broken network requests, inspect logs, and locate failing services.
