As their recruiting partner, we help manage the search from candidate identification and outreach through interview coordination and closing, working closely with the company’s leadership and hiring team throughout the process. This opportunity is being shared on our client’s behalf to expand its reach and connect with exceptional candidates.\nAbout MarketTime\nMarketTime is a growing B2B ecommerce SaaS company helping businesses sell smarter and faster. Our multi-tenant platform powers enterprise customers across multiple industries, processing sensitive financial data-including credit card payments-while maintaining rigorous PCI DSS compliance.\nOur customers-brands, sales reps, and retail buyers-rely on our web applications every day to browse catalogs, build orders, and manage their business, at the office and on the road.\nWe're a fully distributed engineering team that values ownership, collaboration, continuous improvement, and building software the right way.\nAbout the Role\nWe'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.\nYou'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.\nTech Stack\nTypeScript\nAngular\nReact\nPWA\nReact Native / Expo\nREST APIs\nGraphQL\nGitHub Actions\nDatadog RUM\nResponsibilities\nDesign, develop, and maintain customer-facing web applications for buyers, sales reps, and brands.\n\nHelp define the architecture of our next-generation frontend platform, including component design, state management, routing, data fetching, and build tooling.\n\nEvaluate and implement cross-platform approaches (Progressive Web Apps, React Native/Expo) to deliver a great experience across desktop, tablet, and mobile.\n\nBuild offline-capable, resilient experiences for users working with intermittent connectivity.\n\nBuild and maintain a reusable, accessible component library and design system.\n\nMaintain our existing Angular applications and help lead a possible migration to new technology, such as React.\n\nCollaborate with backend engineers to design REST and GraphQL APIs that are intuitive, efficient, and well-suited to frontend needs.\n\nEnsure frontend code meets PCI DSS and security requirements.\n\nOwn frontend performance: bundle size, rendering performance, Core Web Vitals, and perceived responsiveness on real-world devices and networks.\n\nChampion engineering best practices including code reviews, automated testing, CI/CD, observability, and documentation.\n\nUse 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.\n\nTake ownership of features from design through production, including monitoring and operational support.\n\nWork in small, incremental pull requests with a strong emphasis on code reviews, automated testing, and continuous delivery.\n\nMentor and support engineers through technical leadership, design reviews, and pair programming.\n\nTroubleshoot production issues and participate in an on-call rotation as needed.\n\nRequired Qualifications\nOperated as a senior engineer or technical lead on production frontend applications.\n\nStrong expertise with React and its modern ecosystem (hooks, functional components, context, and current state management and data-fetching patterns).\n\nStrong proficiency with TypeScript, including idiomatic use of its type system.\n\nWorking knowledge of Angular, or the ability to quickly become productive in an existing Angular codebase.\n\nDeep understanding of HTML, CSS, browser APIs, and the browser rendering model.\n\nExperience building responsive interfaces that work well across desktop, tablet, and mobile devices.\n\nExperience consuming and helping shape REST and/or GraphQL APIs.\n\nExperience with modern frontend testing tools (e.g., Vitest or Jest, React Testing Library, Playwright).\n\nHands-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.\n\nExperience with modern build tooling (e.g., Vite, webpack) and CI/CD platforms such as GitHub Actions.\n\nSolid understanding of web security fundamentals (XSS, CSRF, CSP, secure token handling).\n\nExcellent communication, collaboration, and problem-solving skills.\n\nA track record of mentoring engineers and leading technical initiatives.\n\nSelf-motivated and effective working in a remote-first environment.\n\nPreferred Qualifications\nExperience building Progressive Web Apps, including service workers, offline storage (IndexedDB), and background sync.\n\nExperience with React Native and/or Expo, including shipping apps to the App Store or Google Play.\n\nExperience testing React Native apps (Jest, React Native Testing Library, Detox or Maestro).\n\nExperience sharing code and components between web and native applications.\n\nExperience leading or contributing to a large-scale frontend framework migration.\n\nExperience building and maintaining design systems or component libraries.\n\nExperience building multi-tenant or white-labeled SaaS applications.\n\nExperience with frontend observability tools such as Datadog RUM or Sentry.\n\nUnderstanding of payment processing systems, PCI DSS, and secure checkout flows.\n\nBackground in ecommerce, B2B wholesale, or field sales applications.\n\nFamiliarity with API security concepts including OAuth 2.0, JWT, authentication, and authorization.\n\nExperience establishing team practices for AI-assisted development (e.g., shared context and conventions files, review standards for AI-generated code, guardrails for sensitive data).\n\nWorking knowledge of Java/Spring Boot or other backend technologies.","description_format":"text","description_chars":6368,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
