UI UX Developer

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, Web Sockets, 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.

• Design and implement UI components for our real-time operational dashboard, timelines, alerts, and camera/video controls.
• Develop and refine user workflows and interactive visualizations (e.g., geospatial overlays, drag/drop control, event timelines).
• Work with React, Type Script, Web Sockets, and REST APIs—while maintaining flexibility for other modern frameworks.
• Collaborate with backend and sensor engineers to build intuitive interfaces for complex system automation.
• Help evolve our design system and component libraries (e.g., shadcn/ui, Tailwind CSS, etc.).
• Translate user and product requirements into well-structured, testable UI features.
• Participate in sprint planning, design reviews, and end-to-end testing.
• Collaborate using Git, Git Hub, Figma, Jira/Confluence, and CI/CD pipelines.
• Work is typically based in a busy remote environment and subject to frequent interruptions. Business work hours are Monday-Friday standard core hours, however some extended or weekend hours may be required.
• Other duties as assigned.

We welcome a wide range of experience levels—from early-career UI developers to more seasoned frontend engineers.

• 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.
• Preferred exposure to:
• React, Next.js, or Vue.js
• Mapbox, geospatial UI, or real-time data visualization
• Tailwind CSS, shadcn/ui, or other component libraries
• Web Sockets, pub/sub architectures (e.g., Kafka), or real-time streaming data
• Figma, design tokens, or UI/UX workflows
• Docker, Kubernetes, or other Dev Ops tools
• 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

The modern threat landscape poses complex challenges. In isolation, individual threats can be managed. However, when coordinated, complexity scales dramatically. Modern security requires detection across all threat types simultaneously. No single sensor or security solution can solve this problem.

LEXSO transforms the operational friction of sensor saturation into a unified, intelligent security system. As an AI-native, MOSA-compliant architecture, LEXSO fuses disparate sensor data directly at the edge. As a result, LEXSO detects, classifies and mitigates threats in sub-second timelines, maintaining a resilient operating picture even when the network is compromised.
