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, The Senior Software Engineer will design, develop, and optimize scalable PHP APIs and web applications, collaborating with product and design teams to support product development and implement best coding practices., Lead full-stack development of cloud-based web applications, designing and implementing front-end and back-end components, CI/CD pipelines, and infrastructure (Terraform/AKS).
