Job description

Apply for Senior Front-end Engineer - Backoffice at Impress in Barcelona, CT, ES. This Full time on site position offers great opportunities for career growth.

Join Impress – Europe’s Leading Health-Tech Innovator! We believe everyone deserves a smile they’ll love . As the largest Ortho clinic chain in Europe, we combine cutting-edge tech with expert care, revolutionizing invisible orthodontics since 2019. With 150+ clinics across 10 countries and rapid growth, we’re improving lives worldwide. We are looking for a Senior Front-end Engineer - Backoffice to join our Onsite Team in Barcelona and lead the transformation of our digital presence.

Why we’re cool:

• Competitive salary
• Teeth aligner and whitening benefits
• Collaborative work environment and positive culture
• Opportunities to grow within a fast-paced, innovative company and real start-up experience with big challenges
• Fresh fruits and healthy snacks at the office

What You’ll Do:

• Own the Clinic Experience: Build and maintain multiple React-based frontends covering clinic agendas, booking and scheduling flows, patient treatment management, and electronic medical records.
• Solve Complex State Problems: Clinical processes have real constraints — availability, resources, treatment stages, market-specific rules. A lot of the difficulty here is modelling state correctly, not styling it.
• Bridge Frontend & Backend: Collaborate closely with backend engineers on API contracts and end-to-end flows that cross several services.
• Raise the Bar on Quality: Solution and architecture reviews before implementation starts, unit and e2e coverage on critical paths, monitoring and error tracking after release.
• Use AI as Part of Your Workflow: AI assistants are part of our everyday workflow — in implementation, review and testing. You will use them daily and help improve the workflows around them.

Requirements:

• 5+ years of frontend development experience.
• Expert-level React — you understand the internals, not just the API.
• Expert-level TypeScript — you write it without thinking twice.
• Strong experience with state management patterns — Redux and server-state tooling such as React Query.
• Solid understanding of modern frontend tooling, build setups and performance optimization.
• Experience working in a product team alongside designers, backend engineers and QA.
• Comfortable using AI coding assistants in your daily workflow.

Nice To Have:

• Booking or scheduling systems — availability, calendars, resource allocation.
• Med-tech or healthcare experience — clinical workflows, EMR, patient data, or regulated domains.
• RxJS — parts of the system use reactive streams for real-time state.
• WebSockets — real-time connections and keeping client state in sync.
• Basic backend knowledge (REST APIs, databases).
• Familiarity with infrastructure concepts (CI/CD, containerization, cloud services).

Tech Stack:

• Frontend: TypeScript, React, Redux, RxJS, React Query, Material UI.
• Backend (for context): Node.js, TypeScript, NestJS.
• Infrastructure: AWS, PostgreSQL, microservices.

At Impress we cultivate a culture of inclusion and diversity. We celebrate our employees' individual strengths, views, and experiences and we encourage all candidates to apply, without regard to race, color, religion, gender identity, sexual orientation, age, national origin, disability, or any other factor.
