Senior React Software Engineer

Job Title: React Developer (Mid-to-Senior | On-Site | U.S. & Canada Travel)
Location: Buffalo, NY – Strictly On-Site
Travel: Required (Primarily within the U.S., occasional travel to Canada)

About the Role
We’re searching for a sharp, experienced, and product-focused React Developer to join our U.S.-based technical launch team. This is a fully on-site role located in Buffalo, NY, and it’s designed for someone who’s done more than just front-end cosmetics—you’ve built and shipped real, scalable applications with React, Typescript, Redux, and modern web tooling. You’ll work closely with our back-end, DevOps, and QA engineers to deliver responsive, performant, and secure user interfaces for mission-critical systems.

You should bring both precision and speed: someone who cares about component
structure, accessibility, state management, and performance—but who can also turn
around enterprise-grade features under tight timelines and changing requirements.

Key Responsibilities

• Build modern, responsive web applications using React, TypeScript, Redux, and associated tooling.
• Translate Figma designs, stakeholder specs, and functional requirements into clean, performant, testable code.
• Work alongside Java developers and DevOps engineers to integrate APIs, error handling, and authentication workflows (OAuth, Cognito, JWT).
• Create, refactor, and maintain reusable UI components across multiple applications.
• Support test automation efforts using Jest, Vitest, or Cypress, and work with QA to build coverage for key workflows.
• Own accessibility (WCAG/a11y), SEO, responsive layout, and frontend performance optimization.
• Implement monitoring, logging, and analytics tools (Google Analytics, SonarQube, etc.) to ensure front-end observability.
• Participate in code reviews, architecture discussions, and Agile sprint planning.
• Travel to client sites (U.S. and Canada) for go-live support, UI validation, and team bootstrapping.

Minimum Qualifications

• 5+ years of professional experience with: JavaScript, TypeScript, React, Redux, Object-Oriented Programming, Electron.js, Docker, Gitlab
• Strong HTML5/CSS3 skills, including SASS, and accessibility best practices
• Familiarity with modern front-end testing tools: Jest, Vitest, Cypress
• Experience working with backend teams and RESTful APIs, ideally using NodeJS, Express, or GraphQL
• Git version control, Agile workflows, and CI/CD familiarity
• Excellent problem-solving and communication skills
• Strong attention to design fidelity, browser compatibility, and UX polish

Bonus Points For

• Experience with: Front-end performance audits, SEO optimization, and analytics instrumentation
• Prior work in healthcare, or government-secure UI systems
• Client-facing experience, including pre-sales support or stakeholder demos

Who You Are

• You live and breathe JavaScript frameworks—but you don’t treat design, accessibility, or mobile performance as afterthoughts.
• You’re used to fast-paced development environments and can pivot quickly when requirements evolve.
• You take ownership: if the build breaks or a layout regresses, you fix it without finger-pointing.
• You collaborate deeply—never working in a silo, always connected to the broader delivery pipeline.
• You’re excited about being part of a core product team with real impact on user experience and client satisfaction.

Work Environment

• This is a strictly on-site role based in Buffalo, NY.
• Travel will be required across the U.S. and Canada for deployment support, validation, and training.
• No hybrid or remote work options available.
