About Us

www.asylonrobotics.com

Asylon automates security operations using robots, software, and AI in order to help its customers protect their people, property, and assets. Asylon was founded in 2015 by three MIT aerospace engineers who have worked on a variety of projects in the aerospace industry from the V-22 Osprey to commercial jet engines to defense systems on Navy destroyers. With our team's strong background in aerospace, Asylon develops products consistent with the quality standards demanded by commercial and military customers. Today, Asylon is a dynamic team that is passionate about robots and committed to building and operating safe, high quality products that solve the greatest challenges facing the robotics and security industries.

We are building a diverse team that creates novel solutions and provides previously unrealized services via robotics. The Asylon team is perfect for those who wish to apply their expertise to revolutionize the robotics industry while expanding their own skillsets.

Product - Robotic Perimeter Security

Asylon develops field deployable infrastructure for automated robots to augment the security teams of our clients. We believe that the true advantages of robotics and automation come when we can have robots and humans working hand-in-hand to increase security and help save lives. We see robots as a means to deliver actionable, timely, and persistent intelligence. DroneCore, our full stack aerial and ground robotics solution, is revolutionizing the way the security industry operates by providing capabilities to security teams that they have never had before.

Position

Asylon is hiring a full stack software engineer to join our Philadelphia team. This engineer will be the primary developer on DroneIQ, the web application that our customers use to manage and interact with their DroneCore deployments. You'll own features end-to-end — from the Vue frontend through the backend services that power it — building dashboards, alerts, geofencing, video playback, mission management, and other tools that security teams rely on daily. You'll also contribute to deeper backend and infrastructure work as needed, but your time will be weighted toward the application layer where your work directly shapes the customer experience.

Due to the nature of the projects worked on in this position, applicants must be a U.S. Person as defined by 22 C.F.R. §120.62. This includes U.S. Citizens, lawful permanent residents, refugees, or asylees.

Primary Duties

Design, build, and maintain features across the full stack of DroneIQ — Vue frontend and backend services
Develop and improve dashboards, alerting workflows, geofence management, video playback, and mission planning interfaces
Build and maintain REST APIs that serve the frontend and integrate with robotics and data systems
Collaborate with robotics and infrastructure engineers to surface real-time telemetry, video, and sensor data in the application
Craft intuitive visualizations that transform complex robotic telemetry, 3D spatial data, and media stored in S3 into actionable insights for security operators
Improve application performance, reliability, and user experience based on customer feedback and operational needs
Contribute to backend services and infrastructure work beyond the application layer as priorities shift
Participate in code review, testing, and CI/CD practices to maintain high code quality

Required Skills and Experience

3+ years of professional full stack software engineering experience
Strong proficiency with a modern frontend framework such as Vue, Angular, or React
Experience building and maintaining backend services in Python, Go, or Java
Comfortable designing and consuming REST APIs
Proficient with databases such as MongoDB, PostgreSQL, or MySQL — schema design, query optimization, and migrations
Proficient with Git and collaborative development workflows
Proficient with Linux as a development environment
Able to own features end-to-end from UI through backend and database

Bonus Points

Experience with Kubernetes or containerized deployments
Experience with real-time data — WebSockets, server-sent events, or streaming protocols
Familiarity with video streaming or playback in web applications (HLS, WebRTC, or similar)
Experience with geospatial data or mapping libraries (Leaflet, Mapbox, Cesium, or similar)
Experience with 3D visualization in the browser — Three.js, WebGL, or similar
Experience with Redis for caching, pub/sub, or session management
Experience with CI/CD pipelines for automated testing and deployment
Has worked on products used by non-technical end users and cares about usability
Experience with Rust

Benefits

Competitive salary and equity packages
401(k) and 401(k) matching
Flexible vacation/sick time
Medical, dental, and vision insurance
Life insurance
Paid time off
Relocation assistance
