Responsibilities

Drive the development of frontend solutions through the full lifecycle – from technical design and implementation to testing and production deployment.

Write well-documented, modular, and reusable code using TypeScript, HTML5, CSS3, and leading frameworks, mainly React.

Collaborate closely with your team, including UX designers, product managers, and backend engineers, to implement responsive, accessible, and user-centric interfaces.

Build, optimize, and maintain performant web applications, ensuring cross-browser compatibility and adherence to our security and accessibility standards.

Actively participate in peer code reviews, contribute to our frontend architecture, and champion a culture of quality, continuous improvement, and data-driven decision-making.

Embrace complex challenges, confidently navigate ambiguous problems to define innovative solutions, and take deep ownership of your projects to deliver high-quality results.

Qualifications

Proven frontend development experience, with a strong ability to demonstrate your work with modern TypeScript, HTML5, CSS3, and component-based frameworks (e.g., React, Vue.js, or Angular).

A strong understanding of UX / UI design principles and their practical application in creating intuitive interfaces.

Solid understanding of web performance optimization, cross-browser compatibility, responsive / adaptive design, and web accessibility standards.

Experience integrating with RESTful APIs, working in cloud-based environments, and using version control (Git) with CI / CD pipelines.

Experience with frontend testing frameworks and test-driven development environments.

Excellent problem-solving skills, meticulous attention to detail, and a pragmatic approach to making thoughtful trade-offs.

Strong communication skills in English, with an aptitude for soliciting and providing constructive feedback and valuing diverse perspectives.

Bonus points (Nice-to-have skills)

Familiarity with design systems.

Knowledge of GraphQL or similar data access solutions, and API design principles.

Experience with frontend mapping frameworks (e.g., OpenLayers, Leaflet, Google Maps API, Esri) – highly relevant to our solar project visualization.

Confidence in leading automation, operational and workflow improvements for the team.
