Location - Knightscope HQ / Sunnyvale (NOT a remote positon)

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

Compensation & Benefits

Base Salary:  $120,000 – $160,000 (DOE)

Equity:  Stock options

Benefits:  Medical, dental, vision, 401(k), paid time off

Location Requirement:  Full-time, on-site at Sunnyvale HQ (305 N Mathilda Ave, Sunnyvale, CA)
