Senior Software Engineer - .NET Fullstack Backend

We’re a growing team, and as we scale, so does our need to expand our engineering team. You’ll be joining a people-focused company, and as a Senior Software Engineer - .NET Fullstack (VPP/CPQ), you will have a strong backend focus to join the core CPQ engineering team at Vendavo. As we transition from a legacy monolith to a modular, cloud-native architecture on AWS, your role will be instrumental in driving this transformation. You will take ownership of modernizing business logic, building event-driven services, and enabling scalable API integrations—all while collaborating across the full stack when needed. 

You should bring deep backend expertise in modern .NET, messaging, and API design, along with the ability to contribute to a React GraphQL frontend as part of end-to-end feature delivery.

• Design and implement microservices in .NET 8 , deployed in Kubernetes (EKS) and integrated with AWS infrastructure 
• Develop robust GraphQL APIs using Hot Chocolate, serving both internal and external clients 
• Integrate backend services with Kafka-based Data Mesh for real-time inbound/outbound data synchronization 
• Replace legacy Azure components (e.g., Service Bus, Blob Storage) with AWS-native equivalents (S3, SQS/SNS) 
• Collaborate with product managers, architects, and engineers across VPP, IAM, and Data Mesh teams 
• Contribute to React frontend codebase (TypeScript GraphQL client) when full-stack delivery is required 
• Uphold high standards in code quality, testing, observability, and performance tuning 
• Mentor junior developers and participate in design reviews and technical planning 

• 5 years of experience in backend development using .NET Core / .NET 6 / .NET 8 
• Proven experience in migrating legacy systems to modular microservice architectures 
• Strong grasp of Domain-Driven Design, asynchronous patterns, and event-driven systems

• Solid understanding of data access patterns, caching (e.g., Redis), and database schema evolution (EF Core, migrations) 
• Experience with Docker, Helm, and Kubernetes deployments 
• Hands-on experience with React and TypeScript 
• Ability to modify and extend existing UI components and data flows (especially those based on GraphQL) 
• Familiarity with GraphQL clients (e.g., Apollo or urql) and REST integration
• Familiarity with AWS cloud services (IAM, EKS, S3, Secrets Manager, SQS/SNS) 
• CI/CD pipeline integration experience (preferably Azure DevOps) 
• Observability tooling (e.g., OpenTelemetry, Application Insights, Prometheus/Grafana) 
• Experience working in the CPQ, pricing, or enterprise quoting domain (Nice to have)
• Familiarity with federated GraphQL schemas and gateway architectures
