Mid Frontend Developer

There are NO limits to your career: come shape the future and be part of a truly unique global culture at OutSystems!

We are seeking a talented Mid Frontend Developer specialising to join our dynamic Digital Experience Team. You will work with independence on complex UI tasks, contribute across multiple project areas, and actively support junior team members.

You will collaborate closely with designers, backend engineers, and business stakeholders practicing a 'win as a team' philosophy where no task is 'not my job' if it helps the project succeed. Together, we deliver high-quality, user-centered applications using low-code and agentic systems.

Join a team that values innovation, continuous improvement, and a growth mindset. If you enjoy hands-on problem-solving, care about craft, and are curious about how AI is reshaping frontend development, this role is for you.

Key Responsibilities

• Discovery & Requirements: Participate in discovery sessions to understand department needs and translate them into frontend solutions, bridging stakeholders and development teams.
• Design System & Components: Build, document, and maintain reusable UI components, ensuring they follow design principles, accessibility standards, and are optimized for AI-assisted workflows.
• Frontend Development: Independently write and maintain complex frontend code in OutSystems (HTML5, CSS3, JavaScript), ensuring performance, cross-browser compatibility, and WCAG compliance.
• OutSystems Expertise: Utilise OutSystems to build, customise, and optimise frontend components.
• AI-Augmented Development: Use AI coding assistants to accelerate development, validate output against quality standards, and share effective AI practices with the team.
• Testing & Quality: Design and execute testing strategies (unit, integration, acceptance), participate in code reviews, and resolve frontend issues independently.
• Debugging & Troubleshooting: Identify and resolve frontend issues and bugs efficiently.
• Continuous Improvement: Stay current with frontend technologies, OutSystems updates, and emerging best practices. Participate in Agile/Scrum ceremonies and team retrospectives.
• Collaboration & Mentorship: Collaborate actively with designers, backend developers, and product stakeholders. Support junior developers through code reviews and knowledge-sharing.

• Strong proficiency in HTML5, CSS3, and JavaScript, with solid command of at least one frontend framework (React, Vue, or Angular).
• Experience in Accessibility (WCAG), responsive design, and cross-browser compatibility.
• Understanding of OutSystems development and design systems (experience contributing to a design system is a plus).
• Comfortable using AI-assisted development tools (code generation, refactoring, documentation) and critically evaluating AI-generated output.
• Excellent communication skills in English, capable of presenting ideas and collaborating with cross-functional teams.
• Ability to work autonomously while being a team player.
• Knowledge of Agile/Scrum methodologies.
• Adaptable, eager to learn, and motivated to grow professionally.

Preferred Skills:

• Experience testing and developing standard OutSystems components.
• Working knowledge of WCAG standards and ability to apply best practices in day-to-day development.
• Proficiency in collaboration and project management tools (e.g. Jira, Confluence, Figma).
• Experience contributing to or maintaining a design system.
