About The Position

We’re seeking multiple UI/UX Developers to join the growing frontend team behind LEXSO (Layered Extended Security Operations)—a modular, microservice-based platform designed to integrate advanced sensors, AI, and automation for enhanced situational awareness and real-time security operations. As a UI/UX Developer, you’ll help design and build the user interfaces and visual workflows that operators depend on for mission-critical decision-making. Our current frontend stack is built with React, WebSockets, and real-time geospatial mapping via Mapbox—but we’re open to web developers from all backgrounds with a passion for intuitive, data-rich design. Whether you’re early in your career or bring years of experience, this role offers the chance to contribute meaningfully to a fast-paced engineering team building an ambitious, high-impact platform.

Requirements

3+ years of experience with JavaScript/TypeScript and modern frontend frameworks (React preferred).
Familiarity with responsive design, web accessibility, and component-based UI architecture.
Understanding of REST APIs, data modeling, and web-based state management.
Strong attention to detail and UX best practices.
Collaborative mindset and effective communication skills.
Bachelor’s degree in Computer Science/Engineering, Human-Computer Interaction (HCI), Software Engineering, Digital Media, or a related technical/design field is required.
Degrees in Interaction Design, UX/UI Design, or Web Development will also be considered
