As Principal Frontend Engineer at Inception
42, you will set technical direction for the frontend systems behind production AI products and platforms. You will remain hands‑on while defining architecture, strengthening design systems, improving performance and reliability, and raising engineering standards across teams. The role works closely with Product, Design, Backend, AI/ML, Security, and Platform Engineering to turn complex capabilities into clear, scalable user experiences.

• Define and evolve frontend architecture across web applications, shared platforms, design systems, and backend‑for‑frontend integrations.
• Design and ship production‑grade frontend systems using Type Script, React, Next.js, and modern browser technologies.
• Establish patterns for modularity, state management, data fetching, routing, error handling, and component composition.
• Build and scale reusable component libraries and design systems that improve product consistency, accessibility, and delivery speed.
• Drive performance engineering across rendering, Core Web Vitals, profiling, code splitting, caching, and bundle optimization.
• Guide integration with REST APIs, GraphQL, Web Sockets, server‑sent events, and event‑driven backend services.
• Define frontend testing strategy across unit, integration, component, end‑to‑end, and visual regression coverage.
• Improve frontend observability, reliability, and operational readiness through meaningful telemetry, error monitoring, and service‑level thinking.
• Embed secure development practices across authentication, authorization, dependency management, browser security, and API consumption.
• Strengthen CI/CD and release workflows for frontend applications, including automated quality gates and repeatable deployment patterns.
• Lead architecture reviews, code reviews, and technical design discussions; mentor senior engineers and grow frontend technical leadership.
• Collaborate closely with Product and Design to make pragmatic technical decisions that improve customer outcomes without compromising long‑term maintainability.
• Evaluate new frontend frameworks, AI‑assisted engineering tools, and AI‑powered interaction patterns when they offer credible product or engineering value.

• Strong frontend engineering fundamentals across JavaScript, Type Script, HTML, CSS, browser behavior, accessibility, and responsive application design.
• Experience shipping and operating complex production applications with React and Next.js; exposure to Angular or comparable frameworks is valuable.
• Demonstrated ability to make architecture decisions across large frontend codebases, shared libraries, and multi‑team delivery environments.
• Practical experience building design systems and reusable component libraries with clear APIs, documentation, and governance.
• Strong understanding of SSR, SSG, client rendering, hydration, caching, performance profiling, and Core Web Vitals.
• Experience with state‑management patterns and integration across REST, GraphQL, Web Sockets, or event‑driven services.
• A disciplined approach to automated testing using tools such as Jest, React Testing Library, Playwright, or Cypress.
• Sound judgment across security, reliability, maintainability, developer experience,…
