• Build interactive data applications, dashboards, and workflow tools using Dash and Streamlit.
• Integrate front-end applications with Databricks data, SQL warehouses, notebooks, jobs, REST APIs, and other enterprise data services.
• Develop Python services and application back ends using FastAPI or similar frameworks to support data retrieval, business logic, authentication, and data visualization.
• Design reusable components, application patterns, and user experiences that can be adopted across multiple data products.
• Implement data visualizations, filters, drilldowns, forms, and other interactive features for business and operational use cases.
• Deploy applications to Kubernetes, including containerization with Docker, Kubernetes manifests or Helm charts, configuration management, secrets, ingress, service discovery, and health checks.
• Deploy and operate applications in Azure, including Azure Kubernetes Service (AKS) where applicable.
• Establish or contribute to CI/CD pipelines for automated testing, container builds, security checks, and application deployment.
• Apply front-end engineering best practices, including responsive design, accessibility, performance optimization, state management, error handling, and maintainable code structure.
• Collaborate with data engineers, analytics teams, product owners, and business stakeholders to translate requirements into usable applications.
• Troubleshoot application, integration, deployment, and performance issues across the front-end, data, and Kubernetes layers.
• Produce technical documentation for application architecture, deployment procedures, configuration, and operational support.

• Hands-on experience containerizing applications with Docker.
• Demonstrated ability to deploy and support applications on Kubernetes; experience with Azure Kubernetes Service (AKS) is strongly preferred.
• Experience with Kubernetes resources and deployment concepts, including pods, deployments, services, ingress, config maps, secrets, namespaces, and health probes.
• Experience working in Microsoft Azure environments and with Azure-based identity, networking, storage, or monitoring services.
• Experience with Git-based source control, automated testing, and CI/CD practices.
• Strong communication and collaboration skills, with the ability to work independently as a contractor in a cross-functional environment.

Preferred Qualifications

• Experience integrating React applications with Python services, Dash, Streamlit, or Databricks-backed APIs.
• Experience with TypeScript, React component libraries, state management, and front-end testing frameworks.
• Experience with FastAPI, Flask, or similar Python web frameworks.
• Experience with Azure DevOps, GitHub Actions, or similar CI/CD platforms.
• Familiarity with OAuth 2.0, OpenID Connect, Azure Entra ID, role-based access control, and enterprise application security.
• Experience with observability tools, application logging, metrics, tracing, and production support.
