Role & Mission

As a Front-End Engineer, you will own the development of high-quality interfaces across our software platforms (cloud, on-premise, and edge deployments) with a strong product-vision.

While your core strength is front-end engineering and design systems, you are comfortable contributing beyond the UI layer working with APIs, backend services, and system integrations when required. We are a small and agile company, requiring flexibility.

This role is ideal for engineers coming from SaaS or scale-up environments who combine frontend craftsmanship with product ownership and versatility.

Your Responsibilities

Frontend & Design Systems

  • Consolidate existing software products and lead cross-products code refactors when needed
  • Build scalable, maintainable web applications using modern frameworks
  • Develop and maintain a coherent design system and reusable component library, in collaboration with our UI/UX designer
  • Ensure high standards of UX, consistency, and visual quality across products

System Integration & Environments

  • Build applications that run across cloud, on-premise, and edge environments
  • Handle diverse data patterns (real-time, batch, intermittent connectivity)
  • Ensure resilience and usability in constrained or operational contexts

Performance & Reliability

  • Optimize frontend performance and application responsiveness
  • Ensure reliability in mission-critical environments
  • Debug production issues across the stack when necessary

Full-Stack Contribution

  • Integrate with backend APIs and data services
  • Contribute to backend or middleware when needed (API design, data handling, debugging)
  • Work across the stack to unblock progress in a small, fast-moving team

Testing & Quality

  • Write unit, integration, and end-to-end tests
  • Maintain high standards of code quality and documentation
  • Participate in code reviews and continuous improvement
