About the Role

We are looking for a talented Full Stack Engineer to join the Knightscope engineering team. In this role, you will design and build the web-based platforms, APIs, and media pipelines that power our Autonomous Security Robot ecosystem. You will work across the entire stack — from responsive front-end interfaces to scalable back-end services — collaborating closely with robotics, cloud infrastructure, and security teams to deliver robust, real-time solutions.

Key Responsibilities

• Develop highly responsive web-based user interfaces for security and monitoring platforms
• Design and implement scalable RESTful APIs, including for live and recorded video/audio streaming
• Integrate Axis Communications network cameras, APIs, and device controls into Knightscope systems
• Build and maintain backend services for:
• Live media pipelines (RTSP, WebRTC, HLS)
• Recorded media ingestion, storage, indexing, and playback
• Develop intuitive front-end features for video review, scrubbing, timestamp search, and playback controls
• Collaborate cross-functionally with robotics, cloud infrastructure, and security teams
• Manage software requirements, priorities, and delivery timelines
• Continuously iterate and improve code quality, performance, and reliability
• Contribute to high-level product and architectural decisions

Required Qualifications

Core Technologies

• Proficiency in Node.js, React, Redux, ES6, HTML5, and CSS3
• Experience building web applications using Python, Java, or JavaScript
• Demonstrated experience with RESTful API development and maintenance
• Working knowledge of a major web framework (Django, Flask, Rails, etc.)
• Experience with SQL and NoSQL databases (MySQL, MongoDB, Amazon DocumentDB)
• Version control with Git or similar

Media & Streaming

• Proficient in live and recorded video/audio technologies: RTSP, HLS, WebRTC, and MP4
• Experience with media storage pipelines including AWS S3, Glacier, or equivalent
• Frontend experience building video players with features such as:
• Timeline scrubbing and frame-based navigation
• Playback speed control and motion-triggered event markers
• Backend services supporting media indexing, retrieval, and playback logging
• Hands-on experience with Axis Communications devices and APIs (e.g., VAPIX, ONVIF)

Cloud & Infrastructure

• Familiarity with AWS services (Amazon S3, SQS, DocumentDB, etc.)
• Proficient in AI-assisted development tools — with a strong emphasis on Claude AI (Anthropic) — as well as GitHub Copilot and Tabnine, to accelerate productivity, code quality, and testing
• Actively develop and program using Claude AI (Anthropic) across the full Software Development Lifecycle (SDLC) — this is a core requirement of the role, not a nice-to-have. Candidates must demonstrate hands-on experience using Claude AI at every phase: (1) Requirements & Planning — analyzing specs and decomposing features; (2) Architecture & Design — evaluating trade-offs and generating API schemas; (3) Implementation — writing and refactoring full-stack code; (4) Code Review & Testing — generating test suites and pre-PR reviews; (5) Debugging & Troubleshooting — diagnosing production issues and reducing MTTR; (6) Deployment & DevOps — authoring CI/CD configs and runbooks; (7) Documentation — producing API references, ADRs, and onboarding guides; and (8) Maintenance & Continuous Improvement — refactoring, dependency audits, and performance improvements post-launch.

Digital Twin

• Understanding of Digital Twin architecture, including real-time synchronization between physical and digital entities
• Experience building interactive 3D or 2D digital representations of physical environments/devices
• Proficiency implementing Digital Twin features using Three.js, Babylon.js, Cesium, or WebGL
• Experience integrating sensor/telemetry data into real-time UI visualizations and dashboards
• Ability to architect and develop APIs that support Digital Twin simulations and live updates
• Familiarity with Digital Twin platforms (e.g., Azure Digital Twins, Siemens, Unity Reflect) is a plus

Bonus Points

• Experience in startup or fast-growth environments
• Familiarity with FedRamp compliance or U.S. Government security protocols
• Strong verbal and written communication skills
