[Remote] Senior Software Engineer (Full-Stack)

Note: The job is a remote job and is open to candidates in USA. Cobalt AI uses automation to elevate physical safety and security in the workplace. We’re hiring a Senior Full Stack Engineer to own the interfaces that security teams rely on every day, including live robot video feeds and real-time alarm dashboards.

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

Skills

• 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

Benefits

• Equity
• Full benefits (medical, vision, dental)
• Flexible work arrangements
