Senior Frontend Engineer

Job description

**⭐** **Who we are** Lodgify is a fast-growing scale-up company leading the vacation rental industry. Backed by $30M in funding, our platform empowers property owners and managers worldwide to efficiently manage and grow their business through technology. Headquartered in sunny Barcelona, we're now a team of 380+ people representing over 60 nationalities, united by a passion for transforming the future of short-term rentals. **⭐️ Role Overview** As a Senior Frontend Developer in our Bookings Group, you will shape the high-traffic, real-time interfaces that property managers rely on every single day. Operating horizontally, you will lead the evolution of our frontend estate—moving large-scale applications into a modern, unified repository while raising engineering standards across multiple product squads. ### ⭐ How will you make an impact? - Architect and refine dense, stateful interfaces, including reservation managers, multi-property calendars, and unified guest messaging. - Collaborate horizontally across squads to build reusable UI patterns, shared component libraries, and robust data-access layers. - Bring surfaces to life with real-time server-sent events and optimistic updates that keep user data instantly synchronized without refreshes. - Lead high-visibility platform migrations, smoothly consolidating domain packages into a single monorepo while keeping production live and stable. - Elevate developer tooling by centralizing strict TypeScript settings, shared test configurations, and fast, signal-rich CI pipelines. - Ensure safe, reliable releases through feature flagging, plan-based functional gating, and diligent post-rollout cleanup. - Drive testing excellence across unit, visual regression, and end-to-end suites while building actionable real-user monitoring. - Mentor mid-level frontend engineers, foster strong code review practices, and write clear technical documentation to empower the entire engineering team. ### ⭐ What makes you a great fit? - You bring 6+ years of production experience building complex React and TypeScript applications, including at least 2 years in a large, shared codebase with multiple collaborating teams. - You have a proven track record of migrating and consolidating large frontend estates incrementally without resorting to high-risk complete rewrites. - You possess deep expertise in state management, real-time data flows (e.g., SSE), and performance optimization for complex web applications. - You have hands-on experience with automated testing tools (such as Vitest, Cypress, or happy-dom) and visual regression testing. - You set high standards for software quality and enjoy establishing shared foundations that elevate the work of surrounding teams. - You embrace a continuous improvement mindset, using feedback, analytics, and monitoring to refine user experiences and technical patterns. - You excel at boundaryless collaboration, seamlessly partnering across product squads to align on architecture and unblock technical dependencies. - You take pride in mentoring peers, sharing technical context, and building a supportive engineering culture.
