Job Title
AI - Software Engineering-Sr Professional I
About your role:
You will build the APIs, services, and cloud-integrated applications that power Fiserv's contact center and AI platform. You will bring deep expertise in .NET Core and Azure, a strong engineering discipline, and the ability to design, implement, and own production-grade systems from requirements to deployment.
You integrate AI agentic capabilities as a natural part of your workflow, leverage tools like Microsoft Copilot to accelerate delivery, and consistently raise the engineering bar through code reviews and cross-team collaboration.
What you’ll do:
Design, build, and maintain RESTful APIs and backend services using .NET Core (C#).
Develop scalable, secure, and high-performance microservices and cloud-native applications on Azure.
Integrate Azure services: App Configuration, Key Vault, Redis Cache, Service Bus, Event Grid, Blob Storage, and Azure SQL.
Build and manage containerized applications using Azure Kubernetes Service (AKS).
Integrate AI agentic models, Azure OpenAI, and third-party AI services into application workflows.
Integrate messaging systems (Azure Service Bus, Kafka) and API management tooling (APIGEE).
Implement CI/CD pipelines using GitLab and Harness; support environment-based deployment strategies.
Design and optimize SQL Server / Azure SQL schemas, stored procedures, indexing, and query performance.
Conduct code reviews and enforce engineering best practices — secure coding, observability, scalability.
Collaborate with DevOps, QA, architects, and product teams in Agile sprint delivery.
Track and document work using JIRA and Confluence; leverage AI/Copilot tools to accelerate development.
Support production systems, troubleshoot incidents, and drive reliability improvements.
What you will need to have:
5+ years of professional backend or full-stack .NET development.
API design best practices and API gateway concepts.
Transaction management and data consistency patterns.
JIRA — sprint planning, work item tracking, and agile delivery.
Confluence — technical documentation and knowledge sharing.
SoapUI / Postman — API testing and validation.
Bachelor's degree or equivalent in Computer Science, Software Engineering, or a related field.

What would be great to have:

Snowflake data platform integration.
Kafka — streaming and advanced messaging patterns.
APIGEE — API management and gateway tooling.
Splunk — logging, monitoring, and operational intelligence.
