Skills
Must have
- 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.

About Knightscope
Knightscope (NASDAQ: KSCP) is a security technology company building the nation's first Autonomous Security Force — autonomous machines, AI-driven software, and elite security professionals operating as one integrated managed service. The Company is on a mission to make the United States of America the safest country in the world. One Team. One Force.
About the Role
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.
Location Requirement: Full-time, on-site at Sunnyvale HQ (No relocation provided)
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.
- 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.
