About the role

Imagine stepping into a role where design and engineering move as one, shaping how humans interact with advanced UAV systems. We're looking for a hybrid Product Designer + Frontend Engineer to own the UX of our UAV products end-to-end from first sketch to production-ready React code. In this role, you'll design and build the user interfaces and data-rich dashboards that operators rely on to work with our next generation UAVs. You'll move comfortably between Figma and code, shaping interaction patterns, visual language, and reusable components while collaborating closely with engineers and domain experts.

At Destinus, we are revolutionizing the defense industry with cutting-edge Unmanned Aerial Vehicles (UAVs). Our innovative technologies are designed to meet the unique demands of modern defense operations, delivering unparalleled speed, precision, and cost effectiveness. Destinus partners with government agencies and defense organizations worldwide to provide advanced solutions for mission-critical operations, enabling a new era of efficiency and technological superiority. Join us in shaping the future of defense with groundbreaking aerospace innovations.

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
  
  

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.
  
  

Who You Are

You're someone who naturally moves between design thinking and engineering execution. This role is 50% product and UX design and 50% frontend implementation, and you enjoy owning the full loop from UX and UI design to production ready React code. You are comfortable turning ideas into intuitive interfaces and then bringing them to life in the product itself. Collaboration is key for you, and you work closely with backend engineers to ensure that what you design is not only elegant but also practical, scalable, and ready for real world use.

Why Join Us?

✨ The Thrill of the Future - Work on cutting-edge projects that redefine aerospace.
✨ Global Innovation Hub - Collaborate with top engineers from all over the world.
✨ Fast-Paced & High-Growth - Experience the rush of working in a rapidly expanding company.
✨ Real Impact - Your work won't be theoretical—it will shape the future of flight.
