The ideal candidate is a frontend-heavy engineer (80% Frontend / 20% Backend split) who has practical experience engineering low-latency, event-driven applications using WebSockets and NodeJS, backed by rigorous test automation frameworks. Core Stack • Frontend: React JS, JavaScript (ES6+), TypeScript • Real-Time & Backend: WebSockets, NodeJS, Java / Spring Boot exposure • Testing: Cucumber, Jest, Cypress, Storybook • Cloud & Infrastructure: AWS (ECS, S3, Lambda, ALB/NLB), Bash / PowerShell scripting Key Responsibilities • Architect & Build Event-Driven UIs: Design and develop highly responsive React JS components for customer-facing terminal applications handling bidirectional, real-time data streaming. • Modernize Legacy Architecture: Analyze existing system flows and actively participate in migrating applications to modern, loosely coupled cloud architectures (AWS, React, Spring Boot). • Enforce Extreme Code Hygiene: Write robust, secure, production-ready code. Leverage automation testing frameworks to build extensive unit, component, and contract tests. • Bridge the Frontend/Backend Gap: Maintain a clean 80/20 balance by building/utilizing NodeJS services to serve frontend applications and collaborating closely with core Java/Spring backend infrastructure teams. • Troubleshoot & Optimize: Proactively diagnose hidden performance issues, network latency spikes within WebSocket connections, and application bottlenecks to ensure operational stability. Required Qualifications & Skills • 8–10 years of overall experience in professional software development and system design. • 2–3+ years of heavy, production-level experience working with React JS. • 5+ years of expert-level depth in JavaScript and modern frontend design patterns. • 2–3+ years of hands-on experience implementing WebSockets (or Socket.io) for real-time, persistent bidirectional communication. • 2–3+ years of experience utilizing NodeJS to build microservices or application wrappers. • 5+ years of continuous experience with advanced automation testing frameworks (Cucumber, Jest, Cypress). • Cloud Proficiency: Confident navigating AWS infrastructure including containerized environments (ECS), static storage (S3), and load balancing (ALB/NLB). • Shell Scripting: Proficient with OS scripting languages like Bash or PowerShell for environment setup and local lab configurations. Nice-to-Have / Preferred Capabilities • Experience or exposure to Micro Frontends or terminal API standards (e.g., CEN/XFS APIs). • Strong debugging familiarity with Java, Spring, or Spring Boot services. • Infrastructure as Code (IaC) experience using Terraform. • Familiarity with enterprise observability tools: Grafana, Splunk, Dynatrace, Datadog, or OpenTelemetry.
