In this role, you will serve as the technical authority on all backend decisions, from Azure SQL cache schema design through write-path logic, Azure Service Bus patterns, and security compliance. You will work closely with the onshore Solution Architect, Integration Lead, and Sr. Front-End Engineer to ensure the backend layer is production-ready and validated every sprint., As the Senior Back-End Engineer, you will set architectural standards, oversee service layer quality, and guide offshore engineering efforts. Your core responsibilities include: * Architecture & Leadership: Lead .NET Core microservices architecture, defining service boundaries, API contract standards, and write-path design patterns across all functional areas. Direct and oversee a pod of offshore back-end engineers by assigning work, conducting code reviews, and ensuring production-ready output. * Database & API Layer Design: Design and own the Azure SQL transactional cache schema. Design and implement REST API endpoints exposed through Azure API Management (APIM), consumed by the React frontend. * Integration & Business Logic: Implement write-path logic that routes commit actions (budget approvals, PO releases, change orders) through Azure Service Bus to OIC flows and back to the ERP. Enforce business logic, data validation, and error handling standards within the service layer. * Pipeline Compliance & Security: Own CI/CD pipeline compliance for backend code, ensuring all commits pass Veracode SAST + SCA security scanning before merging. * Demos & Client Handoff: Lead bi-weekly sprint demos for backend workstreams, ensuring all service layer work is demo-ready on schedule. Resolve and triage backend defects during SIT, UAT, and post-launch hypercare within agreed SLA windows. Conduct knowledge transfer to the client team ahead of the support handoff. ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Develop enterprise-ready applications for Microsoft Teams with Azure resources on modern web technologies](https://www.wearedevelopers.com/videos/187-develop-enterprise-ready-applications-for-microsoft-teams-with-azure-resources-on-modern-web-technologies) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers)
