And we do it all with heart, each and every day.

Position Summary

We are hiring a Staff Full Stack Software Development Engineer with strong React and .NET 8.0 experience to join our Data Engineering team. You will take a lead role in the end-to-end development of a new, critical internal self-service application. Your work on this software solution will be instrumental in our initiative to modernize how data is accessed and managed, enabling teams across the company to more easily work with their own data through the user-friendly tools you build. This project involves a shift from traditional data handling processes, with your primary focus being on creating a robust application that empowers this new approach to data accessibility and decentralized ownership.

About this Role:

This is a high-impact, high-autonomy role suited for a detail-oriented and collaborative individual who thrives on ownership, knows how to apply best practices, and can independently design, build, and maintain production-grade software. While you'll be leveraging your core software engineering expertise, you'll also be at the forefront of our data modernization, gaining deep insights into modern data architectures and practices by building the tools that enable them. You will have access to AI tooling to assist in all aspects of the SDLC.

You will build a solution that will provide:
· Self-Service Data Ingestion - You'll empower application teams to register new Kafka topics, update schemas, and ingest data through a UI, reducing lead times from weeks to minutes.
· Automated Monitoring & Incident Management - You will integrate standardized logging, alerting, and escalation to improve issue resolution and system reliability.
· Data Preview Capabilities - You will enable application engineers to preview how their data will appear in the warehouse during design and before production, allowing for on-the-fly redesign if needed.

About the Project: The Data Self-Service Platform
The Data Self-Service Platform initiative addresses critical challenges in our current data operations. Today, data ingestion is often manual and ticket-driven, leading to delays and limiting self-service for our application teams. You’ll help build a platform that empowers data owners to ingest, transform, and serve their data — giving them full control and accountability for data quality. This platform will enable data producers and consumers to collaborate efficiently, address issues directly, and streamline testing changes.

Key Responsibilities:

• Design, develop, and maintain a full-stack application using React (TypeScript) and .NET 8.0 + ASP.NET Core + gRPC.
• Build out frontend interfaces and backend services — including data models, APIs, caching, and observability.
• Integrate with Kafka-driven pipelines and the Snowflake data platform.
• Own the full lifecycle of the application — from architecture and implementation to CI/CD and monitoring.
• Apply best practices for testing, logging, error handling, and scalability.
• Contribute to infrastructure automation with Terraform.
• Leverage Cursor AI, MCPs and other AI tooling for assisted development and code reuse.
• Mentoring other developers.

Required Qualifications

• 4+ years of hands-on experience in React (with TypeScript) and .NET (preferably .NET 6+ or .NET 8.0).
• Proven experience designing and delivering production-grade full-stack applications.
• Strong understanding of REST and gRPC API development.
• Solid testing skills — including unit, integration, and mocking frameworks.
• Experience with containerized development using Docker, and deploying through CI/CD pipelines (Azure DevOps/Github).
• Familiarity with Kafka or similar event-streaming platforms.
• Experience working with relational databases and/or data platforms (Snowflake, Sql,Server, Postgres).

Preferred Qualifications

• Experience working with Cursor AI, AI-enhanced development environments, or modular automation tools like MCPs.
• Familiarity with Terraform for infrastructure-as-code.
• Exposure to CQRS, Domain-Driven Design, and MediatR.
• Knowledge of structured logging, retry policies, and health check integrations.
• Understanding of secur
