About Air Apps

At Air Apps, we believe in thinking bigger—and moving faster. We’re a family-founded company on a mission to create the world’s first AI-powered Personal & Entrepreneurial Resource Planner (PRP), and we need your passion and ambition to help us change how people plan, work, and live. Born in Lisbon, Portugal in 2018—and now with offices in both Lisbon and San Francisco—we’ve remained self-funded while reaching over 100 million downloads worldwide.

Our long-term focus drives us to challenge the status quo every day, pushing the boundaries of AI-driven solutions that truly make a difference. Here, you’ll be a creative force, shaping products that empower people across the globe.

Join us on this journey to redefine resource management—and change lives along the way.

The Role

As a React Engineer, you will focus on building responsive and accessible user interfaces for our web applications. You will collaborate closely with designers, product managers, and backend engineers to translate wireframes and prototypes into elegant, stable, and scalable front-end experiences that delight our users.

Please note that this post serves the purpose of enhancing our talent pool while we prepare to launch the official job. As soon as it gets posted we will get in touch with you.

This is a fully onsite position, based at our office in Lisbon, where you will collaborate closely with cross-functional teams in person and contribute to a dynamic and fast-paced environment. We are open to support with relocation efforts.

Responsibilities

UI/UX Implementation: Implement high-quality, responsive user interfaces following design specifications, ensuring compatibility across multiple browsers and devices.
Frontend Technologies: Develop and maintain code using modern JavaScript frameworks and libraries (e.g., React, Vue.js, Angular), as well as HTML5, CSS3, and responsive design principles.
Performance Optimization: Continuously improve page load times, rendering performance, and overall user experience.
Integration with APIs: Collaborate with backend teams to integrate with RESTful/GraphQL APIs and ensure smooth data flow between client and server.
Accessibility and SEO: Follow best practices for accessibility (WCAG standards) and search engine optimization.
Testing & Maintenance: Write unit, integration, and end-to-end tests (e.g., Jest, Cypress) to maintain high-quality code, and participate in code reviews.

Requirements

Education & Experience: Bachelor’s degree in Computer Science or related field, around 3+ years of experience in front-end development.
Core Skills: Strong proficiency in JavaScript (ES6+), HTML5, CSS3, and experience with one or more modern web frameworks (React, Vue, or Angular).
Tooling & Workflow: Familiarity with front-end build pipelines (Webpack, Rollup), version control (Git), and CI/CD practices.

What benefits are we offering?

Apple hardware ecosystem for work.
Annual Bonus
Top-tier Health and Life Insurance for peace of mind.
Transportation Budget to support your commute needs.
Coverflex benefits package for meal allowances, well-being, and more.
Childcare support.
Air Conference - an opportunity to meet the team, collaborate, and grow together.
Pension Fund to support your long-term financial planning.
Urban Sports Club membership to keep you active.
Meals 100% free at the hub.

Diversity & Inclusion

At Air Apps, we are committed to fostering a diverse, inclusive, and equitable workplace. We enthusiastically welcome applicants from all backgrounds, experiences, and perspectives. We celebrate diversity in all its forms and believe that varied voices and experiences make us stronger.

Application Disclaimer

Compensation Range: €56K - €70K
