About the role

• Frontend/UX Engineer at Destinus shaping UAV product interfaces with design and React. Collaborate in a hybrid role between UX design and frontend development.

Responsibilities

• **What You´ll Do**
• **Product UI & UX Design**
• Work from product problems and requirements to user journeys, information architecture, and interaction patterns.
• Create low-fi wireframes and high-fidelity mockups in tools like Figma, and evolve them based on feedback and user insights.
• Ensure visual consistency, clarity, and usability across all Destinus UIs.
• **Product UI Development **
• Implement your designs in React, building interactive and user-friendly interfaces for our web applications.
• Maintain a strong focus on clarity, usability, and consistency.
• **Data & Operations Dashboards **
• Design and implement dashboards and monitoring tools that present complex UAV and operational data in a clear, actionable way (tables, charts, maps, status views, alerts).
• **Design System & Reusable Components **
• Help define, implement, and evolve a library of reusable UI components and patterns to ensure consistency and speed across our products — both in design (Figma) and in code (React).
• **Quality & Testing **
• Implement and maintain automated tests for the frontend to ensure reliability of our mission-critical systems.
• **Performance & Reliability **
• Continuously improve the performance, responsiveness, and robustness of our frontend applications, particularly for data-heavy and real-time views.
• **Collaboration **
• Work closely with product managers, backend engineers, and domain experts to understand user needs and workflows, validate design solutions, and ensure smooth integration, deployment, monitoring, and observability of the UI.

Requirements

• **What You’ll Need**
• TypeScript/JavaScript and React - you can design, build, and maintain complex frontends.
• Strong understanding of modern frontend architecture
• Component-driven development.
• State management (e.g. Redux, jotai, Zustand, Recoil, or similar)
• Routing and application structure
• Solid HTML5 & CSS3 skills (or CSS-in-JS/utility frameworks such as Tailwind, styled - components, etc.) and responsive design.
• Experience working with RESTful APIs to integrate frontend with backend services.
• Experience building data-rich UIs (dashboards, tables, charts, monitoring/operations tools).
• Familiarity with testing frontend applications (e.g. Jest, React Testing Library, Cypress or similar).
• Comfortable working in a Linux environment and with Git-based workflows.
• Hands-on UX/UI design experience – you are comfortable going from rough problem statement to wireframes, user flows, and high-fidelity UI proposals, and then implementing them yourself.
• Experience with UX/UI tools (e.g. Figma, Sketch, Adobe XD) for designing flows, layouts, and interactive prototypes.
• Ability to communicate design decisions clearly, incorporating feedback from stakeholders and users.
• **Nice to have**
• Experience collaborating on or contributing to a design system or reusable UI component library.
• Experience with data visualization libraries (e.g. Recharts, D3, Chart.js, ECharts) for building dashboards and operational tools.
• Understanding of accessibility (a11y) and inclusive design best practices.
• Experience with performance optimization in React (code splitting, memoization, profiling, Web Vitals).
• Familiarity with
• AWS (for hosting and delivering frontend applications).
• Docker and container-based development workflows.
• CI/CD pipelines for frontend (build, test, deploy automation).
• Python or other scripting languages for internal tooling/automation.**
