About the Role
The onshore Senior Back-End Engineer leads backend microservices architecture and build quality for the platform, directing a pod of offshore back-end engineers while remaining hands-on in service design, API contract ownership, and CI/CD pipeline governance. 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.

While the center of gravity for this role is backend, we are looking for a full-stack engineer who is comfortable working across the stack - from API and data layer design through the React/typescript frontend that consumes them.
This role is work-from-home (remote) though must be able to commute to client offices in Falls Church, VA as needed (estimated every 2 weeks). This is a full-time W2 employment position with benefits. Please note that this role is tied to a client contract and is structured as an initial 9-month position. Opportunities for extension or long-term placement are highly likely based on client renewal and project performance.

Responsibilities
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 .backend 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.

Required Skills & Experience

• 6–8 years of back-end development experience, with a strong proficiency in Python and TypeScript/Node.js.
• Fullstack engineer with a backend bent - able to contribute to a React/Typescript frontend when needed.
• Demonstrable experience leading or directing offshore back-end engineering teams.
• Strong experience designing and building REST APIs exposed through an API gateway (Azure APIM preferred).
• Proficiency with Azure SQL, schema design, query optimization, and working with a delta-refreshed transactional cache pattern.
• Experience with Azure Service Bus or similar async messaging infrastructure, including retry logic, dead-letter handling, and error queues.
• Solid understanding of microservices architecture and separation of concerns between API gateway, service layer, and data layer.
• Proficiency with Azure DevOps CI/CD pipelines and security-gated build processes (Veracode or similar SAST tools).
• Experience using AI coding assistants (e.g., Claude Code, GitHub Copilot, Cursor) for pair programming, service design, architecture documentation, and code review (AI-assisted development is standard practice on this engagement).
• Strong verbal and written communication skills with the ability to lead sprint demos, run code reviews with offshore teams, and communicate technical decisions to non-technical stakeholders.

Preferred Qualifications

• Prior experience building enterprise financial or ERP applications.
• Experience integrating with Oracle Fusion Cloud or similar ERP platforms via REST/SOAP APIs.
• Familiarity with event-driven architecture patterns: Service Bus, event triggers, idempotency, retry/dead-letter handling.
• Azure-certified or demonstrable hands-on Azure cloud experience (AZ-204 Developer or AZ-305 Solutions Architect preferred).
