Senior Full Stack Developer – Frontend Orientation

Description We're looking for an exceptional and experienced Full Stack Developer with a strong Frontend orientation to join our Web team. This team builds and operates the core user-facing surfaces of Solstice Analytics 's platform — the dashboards, control panels, and data tools used by thousands of customers and internal teams daily. In this role, you will take end-to-end ownership of features and product experiences in production — from pixel-perfect UI to the backend APIs and services that power them — with a clear emphasis on frontend excellence, performance, and user experience. Tech Stack React, Node.js, Express, Webpack, REST APIs, MongoDB, Redis, Kubernetes, AWS Responsibilities End-to-end feature development, from UI/UX design translation and implementation to production rollout and ongoing iteration. Build and maintain high-quality, performant, and accessible React-based web applications at scale. Own the full lifecycle of frontend-heavy features, including the backend APIs and services they depend on. Participate in system and component architecture planning to ensure scalable, reusable, and maintainable frontend solutions. Work closely with Product and Design to translate requirements and wireframes into polished, production-ready experiences. Investigate and troubleshoot complex frontend and integration issues — performance bottlenecks, rendering bugs, state management edge cases, and API contract mismatches. Write high-quality, maintainable code with appropriate test coverage; participate actively in code reviews. Collaborate closely with engineers, product managers, and designers to deliver impactful solutions. Continuously learn and apply best practices in frontend engineering, accessibility, and web performance. Requirements 5+ years of hands-on software engineering experience, including 2+ years focused on frontend development with React. Deep understanding of React internals — component lifecycle, rendering behavior, reconciliation, hooks, context, and performance optimization (memoization, lazy loading, code splitting). Strong proficiency in modern JavaScript (ES2020+), with a solid grasp of async patterns and browser event loop behavior. Proven experience building and shipping production-grade, user-facing web applications. Solid understanding of browser fundamentals: the DOM, CSS layout/rendering, HTTP, caching, and web security (CORS, CSP, XSS/CSRF). Experience building and consuming REST APIs, with comfort owning the backend layer (Node.js) for features you develop. Familiarity with state management patterns and tooling (e.g., Nanostore, React Query, or similar). Proficient in frontend testing practices (unit, integration, and E2E — e.g., Jest, React Testing Library, Cypress/Playwright). Fast learner, able to work independently and as part of a team. Proficiency in English, with strong written and verbal communication skills. Nice to Have: Experience with design systems and component libraries (building or maintaining them, not just consuming). Experience with observability and frontend monitoring (error tracking, real-user monitoring). Background working in data-heavy products (tables, dashboards, charts, real-time data feeds). *Fully remote position (for candidates who are not from Israel). Originally posted on Himalayas
