Job Description

Insight Global is looking for two highly skilled Senior Full-Stack Software Engineers to design, implement, and scale a secure, production-grade platform on Microsoft Azure. The client is building a new cloud-native product line. This is a hands-on, senior engineering role with direct responsibility for application architecture, cloud infrastructure, and developer experience. The ideal candidates are comfortable working in a greenfield environment, making sound architectural decisions, and delivering production-ready systems with minimal oversight.

Key Responsibilities:
• Front-End Development: Design and implement modern, responsive web applications using Blazor WebAssembly and Fluent UI Blazor (in C# .NET). Ensure strong separation of concerns, maintainability, and performance
• Back-End & API Development: Design and implement secure, scalable REST APIs using C# and .NET, as part of a cohesive, end-to-end system. Own API versioning, authentication/authorization, and error-handling strategies.
• Event-Driven Architecture: Design and implement event-driven system boundaries, messaging contracts, and failure-handling strategies using Azure Event Bus. Support local development and debugging using RabbitMQ or equivalent.
• Containerization & Deployment: Build and deploy Docker-based services. Integrate containerized workloads into Azure-hosted infrastructure. Leverage Azure Functions where appropriate.
• Cloud Infrastructure & Security: Design secure-by-default, scalable, production-ready infrastructure. Apply best practices for identity, access control, secrets management, and network security.
• Collaboration & Engineering Excellence: Participate in architecture discussions, code reviews, and technical decision-making. Treat documentation as a core architectural artifact, capturing system intent, constraints, and rationale using Markdown and Mermaid.
• Reliability, Scale, & Observability: Design systems for high availability, fault tolerance, and graceful degradation. Ensure services are observable, diagnosable, and supportable in production. Anticipate scaling characteristics and failure modes before they occur.
• Database Design and Management: Design, implement, and evolve cloud-based data models and persistence strategies (Cosmo DB, SQL, etc.). Utilize LINQ and Entity Framework for data access and management.
• Concurrency and Multi-threading: Implement and manage concurrency and multi-threaded processes to ensure efficient application performance.
• Collaboration: Work closely with cross-functional teams to gather requirements and deliver high-quality software solutions.
• CI/CD & Automated Testing: Develop robust automated test suites and contribute to CI/CD practices that support reliable, repeatable deployments.
