- Build and maintain data ingestion pipelines and work with large datasets using Azure Databricks and Delta Tables.
- Develop cloud‑native applications leveraging AKS/Kubernetes, Azure API Management, Azure Service Bus, MongoDB/Cosmos DB, and vector databases.
- Establish and maintain automated build, integration, and deployment pipelines using GitHub Actions.
- Implement strong engineering practices across testing, code reviews, observability, security, performance, and reliability.
- Troubleshoot complex production issues, conduct root-cause analysis, and drive issues through resolution.
- Partner with product, design, QA, engineering, and business stakeholders to translate requirements into effective technical solutions.
- Contribute to architectural decisions and advocate for scalable, consistent engineering standards across the stack.
- Take ownership of individual deliverables and drive work forward with minimal supervision.

What You Bring

- Strong understanding of application security, including authentication, authorization, input validation, and data protection.
- Strong verbal and written communication skills, with the ability to clearly explain technical approaches and trade‑offs to both technical and business audiences.
- A collaborative mindset combined with the ability to independently own and deliver work.
