About this opportunity
Cobalt AI, LLC lists this Senior Software Engineer (Full-Stack) opportunity in denver, Colorado. Review the employer’s description below for duties, qualifications and application requirements.
Job description
Cobalt AI uses automation to elevate physical safety and security in the workplace. Our platform, Cobalt Monitoring Intelligence, is a hybrid AI system, cloud-hosted with edge-deployed hardware, that provides human-verified, real-time monitoring of surveillance cameras, alarms, and robots across enterprise locations.
We’re hiring a Senior Full Stack Engineer to own the interfaces that security teams rely on every day, including live robot video feeds, event triage workflows, real-time alarm dashboards, and fleet management tools built in React and TypeScript. You’ll also work across the backend (Django/Python, GraphQL) to build the APIs that power those experiences.
Responsibilities
Build and refine real-time security dashboards, event triage interfaces, and fleet management tools used by security teams 24/7
Design and implement complex, interactive UIs — canvas rendering (environment maps, robot positioning), data visualization, live robot video via WebRTC, and subscription-driven event streaming
Own component architecture in a monorepo and contribute to a Storybook-driven design system
Build and extend the GraphQL API — queries, mutations, and WebSocket subscriptions — serving all frontend applications
Work with Django models in PostgreSQL — multi-tenant data isolation, schema design, query optimization, and migrations
Ship full-stack features end-to-end — from React components to GraphQL mutations to Django models and background jobs
Partner with the CDS and ML teams on the detection-to-event pipeline
Write well-tested code with strong observability — tracing, structured logging, and metrics
Participate in code reviews, architectural discussions, incident response, and on-call rotations
Qualifications
5+ years of professional software engineering experience, with depth in frontend development
Strong proficiency in React and TypeScript — opinionated about component architecture, state management, and rendering performance
Experience building complex, interactive UIs — canvas/2D rendering, real-time streaming, data visualization, or WebRTC
Backend fluency in Python and Django — building GraphQL APIs, writing migrations, and optimizing ORM queries
Solid understanding of PostgreSQL — data modeling, indexing, and query performance
Comfort working in a monorepo with shared packages, generated types, and cross-team code ownership
Experience deploying to AWS and working with containerized applications
Why Work for Us?
Competitive salary, equity, and full benefits (medical, vision, dental). Flexible work arrangements. A proven platform, an expanding customer base, and the opportunity to shape the engineering org at an inflection point.
Salary Range: $160k - $210k (actual compensation will be determined based on experience, location, and other factors permitted by law)
