[Hiring] Senior Frontend Engineer @Fresno Summit Advisors

Role Description

We're looking for a Senior Frontend Engineer (TypeScript/Angular/React) to help build and evolve the user-facing side of our ecommerce platform. You'll work on our existing Angular applications today while playing a key role in shaping our next-generation frontend: a single platform, potentially React-based, designed to deliver a fast, consistent experience across desktop, tablet, and mobile, including offline-capable and installable experiences.

You'll work closely with Product, Design, and backend engineers to turn complex B2B workflows into intuitive, performant interfaces. Beyond writing code, you'll mentor other engineers, help define frontend architecture and standards, and drive engineering best practices across the team.

Qualifications

• Operated as a senior engineer or technical lead on production frontend applications.
• Strong expertise with React and its modern ecosystem (hooks, functional components, context, and current state management and data-fetching patterns).
• Strong proficiency with TypeScript, including idiomatic use of its type system.
• Working knowledge of Angular, or the ability to quickly become productive in an existing Angular codebase.
• Deep understanding of HTML, CSS, browser APIs, and the browser rendering model.
• Experience building responsive interfaces that work well across desktop, tablet, and mobile devices.
• Experience consuming and helping shape REST and/or GraphQL APIs.
• Experience with modern frontend testing tools (e.g., Vitest or Jest, React Testing Library, Playwright).
• Hands-on experience using AI coding tools in professional work, with sound judgment about when to trust, verify, or discard their output, and a clear understanding of what data must never be shared with them.
• Experience with modern build tooling (e.g., Vite, webpack) and CI/CD platforms such as GitHub Actions.
• Solid understanding of web security fundamentals (XSS, CSRF, CSP, secure token handling).
• Excellent communication, collaboration, and problem-solving skills.
• A track record of mentoring engineers and leading technical initiatives.
• Self-motivated and effective working in a remote-first environment.

Requirements

• Design, develop, and maintain customer-facing web applications for buyers, sales reps, and brands.
• Help define the architecture of our next-generation frontend platform, including component design, state management, routing, data fetching, and build tooling.
• Evaluate and implement cross-platform approaches (Progressive Web Apps, React Native/Expo) to deliver a great experience across desktop, tablet, and mobile.
• Build offline-capable, resilient experiences for users working with intermittent connectivity.
• Build and maintain a reusable, accessible component library and design system.
• Maintain our existing Angular applications and help lead a possible migration to new technology, such as React.
• Collaborate with backend engineers to design REST and GraphQL APIs that are intuitive, efficient, and well-suited to frontend needs.
• Ensure frontend code meets PCI DSS and security requirements.
• Own frontend performance: bundle size, rendering performance, Core Web Vitals, and perceived responsiveness on real-world devices and networks.
• Champion engineering best practices including code reviews, automated testing, CI/CD, observability, and documentation.
• Use AI-assisted development tools (e.g., Claude Code, Cursor, GitHub Copilot) to accelerate delivery, while owning the correctness, security, and maintainability of everything you ship.
• Take ownership of features from design through production, including monitoring and operational support.
• Work in small, incremental pull requests with a strong emphasis on code reviews, automated testing, and continuous delivery.
• Mentor and support engineers through technical leadership, design reviews, and pair programming.
• Troubleshoot production issues and participate in an on-call rotation as needed.

Benefits

• Experience building Progressive Web Apps, including service workers, offline storage (IndexedDB), and background sync.
• Experience with React Native and/or Expo, including shipping apps to the App Store or Google Play.
• Experience testing React Native apps (Jest, React Native Testing Library, Detox or Maestro).
• Experience sharing code and components between web and native applications.
• Experience leading or contributing to a large-scale frontend framework migration.
• Experience building and maintaining design systems or component libraries.
• Experience building multi-tenant or white-labeled SaaS applications.
• Experience with frontend observability tools such as Datadog RUM or Sentry.
• Understanding of payment processing systems, PCI DSS, and secure checkout flows.
• Background in ecommerce, B2B wholesale, or field sales applications.
• Familiarity with API security concepts including OAuth 2.0, JWT, authentication, and authorization.
• Experience establishing team practices for AI-assisted development (e.g., shared context and conventions files, review standards for AI-generated code, guardrails for sensitive data).
• Working knowledge of Java/Spring Boot or other backend technologies.
