About MarketTime

MarketTime 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.

Our 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.

We’re a fully distributed engineering team that values ownership, collaboration, continuous improvement, and building software the right way.

About the Role

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.

TypeScript • Angular • React • PWA • React Native / Expo • REST APIs • GraphQL • GitHub Actions • Datadog RUM

Responsibilities

• 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.

Required 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…
