Senior Full Stack Engineer

Key Responsibilities

• Design and build scalable RESTful and GraphQL APIs supporting live media pipelines, alert management, reporting, investigation workflows, and 3D digital twin data feeds.
• Develop highly responsive, accessible web interfaces for the Signals platform — including real-time dashboards, alert management views, investigation workspaces, and multi-stream video review with timeline scrubbing, frame-based navigation, and playback controls.
• Architect and implement the 3D digital twin layer: real-time synchronization between physical robot state and digital environment using Three.js, Babylon.js, Cesium, or WebGL; sensor/telemetry data integration into live spatial visualizations.
• Build and maintain live and recorded media pipeline integrations: WebRTC, RTSP, HLS, MP4 playback, and media storage/retrieval via AWS S3 and equivalent cloud services.
• Integrate network camera APIs and device controls (Axis VAPIX, ONVIF, or equivalent) into Knightscope platforms.
• Build backend services for media indexing, retrieval, playback logging, and archival using AWS S3/Glacier or equivalent.
• Maintain high code quality through peer code reviews, automated testing, and CI/CD practices; leverage AI-assisted development tools (GitHub Copilot, Claude.ai, or equivalent) to improve productivity and code quality.
• Collaborate cross-functionally with robotics, AI/ML, audio/video, DevOps, and UI/UX teams; contribute to high-level product and architectural decisions.

Required Qualifications

• 7–10 years of full stack software engineering experience with a strong focus on production-grade web applications; enterprise SaaS, security operations, or IoT-connected platforms strongly preferred.
• Expert proficiency in React, Redux, Node.js, ES6/TypeScript, HTML5, and CSS3; experience with component-based design systems and WCAG AA accessibility standards.
• Strong backend experience in Python, Java, or Node.js; proficiency with a major web framework (Django, Flask, Rails, Express, or equivalent) and RESTful/GraphQL API design.
• Hands-on experience with live and recorded video/audio technologies: WebRTC, RTSP, HLS, MP4 — including frontend video player development with timeline scrubbing, frame navigation, and event markers.
• Experience building 3D or 2D interactive digital twin interfaces using Three.js, Babylon.js, Cesium, or WebGL — including real-time sensor/telemetry data integration and live spatial visualization.
• Solid experience with AWS services: S3, SQS, DocumentDB, Kinesis, or equivalent cloud-native media and data pipeline services.
• Proficiency with SQL and NoSQL databases (MySQL, MongoDB, Amazon DocumentDB, or equivalent); experience with media indexing and retrieval patterns.
• Familiarity with network camera APIs and protocols (Axis VAPIX, ONVIF, or equivalent) is a strong differentiator.
• Experience with FedRAMP compliance or U.S. Government security protocols is a plus.
• BS in Computer Science, Software Engineering, or related field — or equivalent professional experience.
