Job descriptionDeliver microservices that enable seamless omni‑channel experiences across business and customer platforms, ensuring consistency, personalization, and performance. Build secure service layers to support customer authentication (SSO, OAuth, Azure Active Directory B2C) and user data management. Enable features such as software subscription lifecycle management, self‑service account tools, and dynamic content personalization. Integrate microservices with enterprise systems including Salesforce Sales / Service / Experience Clouds, Oracle ERP modules, Aria billing solutions, and QSC’s proprietary applications. Build robust and scalable data services for near‑real‑time data exchange, synchronization, and transformation across platforms. Leverage Azure Data Factory, Azure SQL, Cosmos DB, and Azure Storage for backend data processing and persistence strategies. Define and enforce data modeling, API versioning, and service documentation standards. Implement service‑level security using OAuth2, JWT, role‑based access control (RBAC), and Azure Key Vault for secrets management. Establish monitoring, telemetry, logging, and alerting practices using Azure Monitor, Application Insights, and Log Analytics. Optimize microservices for high availability, disaster recovery, and scalability across global Azure regions. Conduct code reviews, security reviews, and performance testing for all services prior to production release. Serve as a technical leader and mentor across engineering teams, fostering a high standard of technical excellence. Lead architecture discussions, code reviews, and technical workshops for internal engineers and contractors. Collaborate with enterprise architects, QA leaders, DevOps engineers, and platform owners to ensure system coherence. Stay current with evolving Azure capabilities and new architectural patterns, driving continuous innovation within the team. Advocate for “shift‑left” practices, ensuring quality, security, and scalability considerations are built early into the development lifecycle. 10+ years of progressive software engineering experience with deep expertise in backend systems development. 5+ years architecting, building, and operating microservices on Microsoft Azure. Extensive experience integrating with enterprise platforms such as Salesforce and Oracle via APIs, events, and middleware. Deep knowledge of .NET Core / .NET 6+, C#, Azure SDKs, Azure DevOps, and modern API design practices. Demonstrated experience enabling customer‑facing experiences such as portals, self‑service capabilities, and subscription management. Hands‑on experience with Azure Kubernetes Service (AKS) and containerized microservices architecture is strongly preferred. Experience applying security best practices for cloud‑native services, including OAuth2, API security, and compliance. Experience working in agile development environments and collaborating with cross‑functional teams (UX, Product, QA, Infrastructure). Bachelor’s degree in Computer Science, Software Engineering, Information Systems, or related field; Master’s degree preferred. Microsoft Certified : Azure Solutions Architect Expert or Azure Developer Associate strongly preferred. Exceptional problem‑solving skills, strategic thinking, and a strong bias toward execution. Outstanding communication skills — able to clearly convey complex ideas and technical concepts to both engineering and business audiences. Strong passion for innovation, modern cloud technologies, and customer‑centric solution building. Self‑starter with the ability to thrive in a fast‑paced, dynamic, and collaborative environment. Committed to fostering a culture of learning, mentorship, and engineering excellence.
