Bringing a strong knowledge of how people use computer systems you’ll craft world‑class Node.js applications—defining standards, frameworks, and best practices to ensure scalability, maintainability, and fault tolerance across our microservices landscape. This is a 6‑month long contract role. What You’ll Do UI/UX & HCI Leadership: Design and validate user interfaces with a strong grounding in human–computer interaction principles, wireframing flows, optimizing accessibility (WCAG), and ensuring responsive, performant experiences. API & Component Design: Define RESTful and event‑driven APIs alongside reusable UI component libraries that promote consistency, scalability, and ease of use. Cross-Functional Collaboration: Partner with product designers, UX researchers, QA engineers, and DevOps to translate user needs into polished, reliable software.

Mentorship & Reviews: Guide engineers on full‑stack best practices, conduct paired design/code reviews, and evangelize design‑system thinking. Delivery & Iteration: Drive agile ceremonies, estimate work holistically (UI + API), and manage releases—ensuring seamless coordination between front‑end and back‑end teams. Requirements 5+ years of professional experience with Node.js and Express.js in production. Strong front‑end expertise with Vue.js (or React/Angular), including component design, state management, and performance optimization. Demonstrated understanding of UI/UX fundamentals and HCI research methods—experience with wireframing tools (Figma, Sketch) and usability testing. Proven ability to own full‑stack features: designing database schemas, APIs, UI components, and ensuring end‑to‑end observability. Excellent communication skills—comfortable presenting design proposals, architectural diagrams, and user-flow mockups to diverse audiences. Experience driving CI/CD pipelines that include front‑end build steps, automated UI tests, and back‑end deployments. Nice To Have Prior work building design systems or component libraries.
