Sr Front-end Engineer - HTS Stays & Packages

About the job

Did you know Hopper technology powers some of the largest travel portals in the world? Our Hopper Technology Solutions (HTS) platform drives travel purchases for major global brands — from banks to airlines to fintech leaders. This platform is essentially a configurable, multi-tenant travel commerce engine, enabling partners to launch world-class hotel and travel booking experiences faster, with less custom engineering.

Our Stays & Packages team focuses specifically on accommodation and bundled travel experiences: hotels, alternative stays, and packages combining flights, cars, and lodging. We build the booking flows, search experiences, checkout journeys, and platform capabilities that power these products across multiple partner portals worldwide.

We’re looking for a Senior Frontend / Full-Stack Engineer who wants to work at the intersection of travel product, platform engineering, and user experience.

This role isn’t just about shipping UI features; it’s about shaping how lodging and package booking experiences scale across partners while maintaining performance, usability, and long-term maintainability.

What would your day-to-day look like

- Work with a group of top-tier engineers in a low-process environment powered by trust and autonomy

- Drive decisions and consensus asynchronously with thoughtful documentation

- Ship fast. Learn fast. Repeat. Build new features from top to bottom, from UX to database

- Architect scalable front-end solutions that allow us to efficiently launch new portals.

- Work directly with PMs and business partners to help define and refine our roadmap. Your voice matters.

- Collaborate cross-functionally with a diverse group of people, giving and receiving feedback for growth

An ideal candidate has:

- Deep expertise in React with modern compiler-driven patterns (functional components, hooks, performance optimizations, server-side rendering, hydration, and advanced state management).

- Proficiency in TypeScript, with experience developing and maintaining enterprise-scale applications.

- Advanced CSS knowledge (Tailwind, SCSS, CSS-in-JS, animations, and handling browser quirks).

- Familiarity with contemporary frontend tooling (e.g., React Query/TanStack ecosystem, Tailwind or design-token-based styling, modern build tools like Vite). Experience working in monorepos (e.g., Turbo, Nx, pnpm workspaces) is a plus too.

- Solid frontend architecture fundamentals: performance, accessibility, responsive design, testing, and maintainability

- Experience optimizing frontend performance (lazy loading, code-splitting, caching strategies, Lighthouse optimizations, etc.).

- Experience working on complex product flows such as e-commerce, travel, marketplace, or fintech applications.

- Ability to balance shipping product features with long-term platform thinking in multi-brand or white-label environments

- Familiarity with SSR and static site generation (e.g., Next.js) for SEO-friendly experiences.

- A passion for writing testable code knowing what to test, what not to test, and what kinds of tests matter in front-end applications.

Bonus: Full-stack engineers with a frontend tilt are very welcome, especially those comfortable collaborating across API design, backend systems and cloud platforms (GCP, AWS, etc.). This is a nice to have, but not mandatory.

Perks and benefits of working with us:

- Well-funded and proven startup with large ambitions, competitive salary and upsides of pre-IPO equity packages

- Hopper offers group medical and dental insurance to full-time employees.

- Hopper offers life insurance with short term and long term disability coverage.

- All employees and dependents have access to telemedicine services, anytime, anywhere.

- Please ask us about our very generous parental leave, much above industry standards!.

- Unlimited PTO.

- Carrot Cash travel stipend.

- Flexdesk Access Pass & Work-from-home stipend.

- Entrepreneurial culture where pushing limits and taking risks is everyday business.

- Open communication with management and company leadership.

- Small, dynamic teams = massive impact.
