Position Summary
We’re looking for a Full Stack Developer to help expand and refine the LEXSO (Layered Extended Security Operations) platform—a modular, microservice-based system designed to orchestrate real-time data from sensors, cameras, AI engines, and automation tools across security operations environments.
As a full stack engineer, you’ll contribute across both frontend and backend domains, building scalable microservices, powerful APIs, and responsive user interfaces. You'll work alongside specialists in automation, sensor fusion, and distributed systems to solve complex challenges in a modern DevOps environment.
This is a great opportunity for someone with a few years of experience who wants to take ownership of major features and help drive architectural and system-level improvements in a fast-moving, impactful platform.
RESPONSIBILITES:
- Design and develop backend services using FastAPI, Kafka, PostgreSQL, and Docker.
- Build and maintain frontend interfaces using React, TypeScript, and real-time visual components (e.g., WebSockets, Mapbox).
- Create and maintain REST APIs and Kafka consumers for automation and alerting workflows.
- Integrate a wide range of devices and sensors (e.g., PTZ cameras, LiDAR, radar, drones) into reusable service modules.
- Contribute to component design, service orchestration, and data modeling.
- Participate in sprint planning, peer reviews, and CI/CD deployment workflows.
- Debug, test, and optimize both backend and frontend features.
- Collaborate using Git, GitHub, Jira, Confluence, and automated build pipelines.
- Work is typically based in a 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:
- Proficiency with Python (preferably FastAPI or similar frameworks)
- Proficiency with JavaScript/TypeScript and React or another frontend framework
- Experience designing and consuming REST APIs
- Familiarity with relational databases (e.g., PostgreSQL) and schema design
- Experience with Docker, Git-based workflows, and Agile teams
- Strong problem-solving skills and attention to software quality
- Preferred:
- Exposure to:
- Kafka, MongoDB, or OpenSearch/Elastic
- js, Tailwind CSS, shadcn/ui
- OAuth/JWT authentication flows (e.g., via Keycloak, Auth0)
- Real-time systems: WebSockets, pub/sub architectures
- IoT, robotics, or physical device integrations
- CI/CD tooling: GitHub Actions, ArgoCD, Kubernetes
- Bachelor’s degree in Computer Science, Software Engineering, Electrical Engineering, or a related technical field is required. Candidates with equivalent degrees (e.g., Robotics, Mechatronics, Data Science, Cybersecurity) will also be considered.

Company Info
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.
