POSITION SUMMARYTri-State is seeking a practical, hands-on Front-End Application & Web Platform Engineer to support both our public web presence and a growing internal application ecosystem. In this role, you will focus on taking functional, internally designed applications from approximately 85-90% complete to polished, production-ready quality, as well as maintaining them post-release.
Additionally, you will take full ownership of rebuilding and modernizing the existing public websites as they migrate from legacy ASPX implementations to a modern, AWS-hosted static architecture. This is a role focused on execution, user experience refinement, and front-end reliability. You will collaborate directly with the Technical Lead, receiving existing source code, functional APIs, and established architecture, and independently driving software across the finish line.
KEY RESPONSIBILITIESInternal Applications & Intranet Platform- Application Completion & Refinement: Complete and refine partially finished application front ends, connecting existing UI components to REST APIs and ensuring seamless client/server data flow.
- UI/UX & Workflow Enhancements: Improve forms, tables, filters, tabs, modals, navigation, client-side validation, and application workflows.
- State & Error Handling: Implement appropriate loading, success, warning, error, and empty states; improve client-side validation and error handling.
- Troubleshooting & Bug Fixing: Troubleshoot JavaScript and browser-side behavior, diagnose layout and spacing issues, fix responsiveness, and resolve cross-browser compatibility bugs reported by users.
- Security & Integration: Work with authentication, sessions, JWT-based APIs, CORS, and role-based UI behavior.
- Component Standardization: Refactor repeated interface patterns into reusable components and utilities to help establish consistent UI standards across internal applications.
- Backend Alignment & Escalation: Make small supporting backend/API tweaks when appropriate while recognizing when changes impact underlying architecture or business logic, escalating those issues to the Technical Lead.
- Testing & Deployment Maintenance: Thoroughly test changes before production deployment and provide ongoing maintenance and improvements post-release.
Public Website Platform Modernization- Platform Migration: Rebuild legacy ASPX public websites using modern HTML, CSS, and JavaScript within a static-site architecture hosted on AWS.
- Branding & Component Design: Preserve existing branding, content, and functionality while building responsive, reusable page and content components.
- Dynamic Integration: Integrate dynamic content delivered through APIs, S3, or other backend services to maintain site flexibility without relying on a traditional CMS for every update.
- Performance & Optimization: Optimize site performance, Core Web Vitals, accessibility, browser compatibility, and maintain analytics/tracking integrations.
- Technical SEO / AEO / GEO Implementation: Execute technical discovery and search recommendations supplied by Marketing and analytics teams, including semantic HTML, page metadata, canonical URLs, structured data/schema markup, XML sitemaps, robots.txt, content hierarchy, and image optimization.
REQUIRED QUALIFICATIONS- Relevant Experience: Approximately 3-6 years of professional experience as a Front-End Engineer, Web Application Developer, UI Engineer, or Full-Stack Developer with a strong front-end focus (demonstrated capability may be prioritized over formal degrees or rigid years of experience).
- Core Front-End Proficiency: Strong, practical mastery of HTML5, CSS, and modern JavaScript.
- Application Troubleshooting: Proven ability to dive into existing source code, debug complex browser-side issues, and resolve front-end state/event handling bugs using browser developer tools.
- Web & API Integration: Solid working knowledge of REST APIs, JSON, asynchronous requests, HTTP, CORS, authentication/authorization mechanisms (JWT), and client/server architecture.
- Responsive Design & Version Control: Demonstrated skill in building responsive layouts, cross-browser compatibility, and source control using Git.
- Self-Direction & Execution: Strong independent problem-solving skills with the ability to take a functional API and high-level workflow description and independently determine what needs to be fixed or completed.
PREFERRED QUALIFICATIONS- AWS Cloud Environment: Experience with AWS cloud services (S3, CloudFront, Lambda, DynamoDB) and serverless web application patterns.
- Modern Tooling: Proficiency with TypeScript and modern front-end build tooling/workflows.
- Technical SEO & Search Infrastructure: Familiarity with technical SEO standards, Schema.org structured data, Google Search Console, and web analytics tools.
- Accessibility & Performance: Understanding of Web Content Accessibility Guidelines (WCAG) and Core Web Vitals performance optimization.
- DevOps Integration: Exposure to CI/CD pipelines or automated deployment workflows
