Job description

Knightscope is seeking a Senior Full Stack Engineer to design, build, and own the web platform powering the Signals intelligence platform and the ASR robot software stack across our full fleet - including the K1, K1Hv2, H1, K5, and K7. Signals is a complex, multi-layered web application integrating live robot telemetry, AI-driven alert management, real-time audio/video streaming, and a 3D digital twin visualization layer. This role is the bridge between backend services and the operator-facing experience - you will own full-stack feature delivery from RESTful API design through frontend implementation, and contribute to the architectural decisions that shape how security operators interact with a nationwide robot fleet., * 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.
  • Contribute to ASR robot platform software across the full fleet - including check-in/checkout flows, IMU bring-up, configuration management, and streaming and storage pipelines.
  • 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.

Requirements

Do you have experience in Video streaming?, Do you have a Bachelor’s degree?, * 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.
