POSITION SUMMARY

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.

RESPONSIBILTIES

  • 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, TypeScript, WebSockets, 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, GitHub, 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.

QUALIFICATIONS:

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

  • 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.
  • 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 WebSockets, pub/sub architectures (e.g., Kafka), or real-time streaming data Figma, design tokens, or UI/UX workflows Docker, Kubernetes, or other DevOps 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

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
