The role involves modernizing CPQ business logic, implementing microservices, developing GraphQL APIs, and mentoring junior developers within a cloud-native architecture.
As a company we are growing, and as we scale up, we focus on growing our CPQ platform team as well. We’re looking for a Senior .NET Full Stack Developer with 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.
THE OPPORTUNITY
- Lead refactoring of critical CPQ business logic from SQL Server stored procedures into maintainable, testable .NET application code
- 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
THE SKILL SET
- 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
- Proficiency with MassTransit and message brokers (Kafka, Azure Service Bus, AWS SQS/SNS)
- 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
- Exposure to IAM and OIDC/OAuth2-based authentication/authorization flows
- Previous involvement in Data Mesh or large-scale data synchronization projects
THE BENEFITS
- Working within a team of friendly, skilled people where help is always within reach
- Professional growth and development opportunities
- Use of modern tools and access to experts
- Team spirit in the workplace, with weekend retreats and fun team activities
- Opportunities to learn a new field and get a deep understanding of enterprise tech
- Flexible working hours without micromanagement
- Personal freedom and focus on individual responsibility
- Company-sponsored events for employees, volunteer tech talks, and tournaments
- Weekly English classes, international travel opportunities
- 25 days of paid vacation + 4 additional company days off to recharge your batteries (1 day each quarter) + 2 days paid for charity activities
- Monthly benefits allowance, meal contributions
- MultiSport card available
- Modern cozy offices in Prague, Hradec Kralove, and Ostrava, no large open-space floors or cubicles, rec room with games and books
- High-end laptop (Dell XPS or Mac) and smartphone (Samsung S or iPhone), including personal use
- Option to use discounted unlimited mobile plan for family members
- O'Reilly Learning
