About the opportunity
The Dayforce Data Platform team is building the next generation of our enterprise data platform. We are looking for a software developer who enjoys building services, APIs, frameworks, and core platform components that power our enterprise data platform. This is a software engineering role focused on platform engineering, reusable systems, developer tooling, and cloud-native services that enable analytics, AI, and customer-facing products.

In this role, you will design and develop the software components that power our cloud-native data platform, including ingestion services, processing frameworks, APIs, orchestration. You'll write production software in Python and C#, build APIs, and develop scalable data services alongside modern data platform components. Success comes from building production-quality services, APIs, frameworks, and platform capabilities that enable data products, analytics, and AI at scale.

You will work closely with software engineers, data scientists, product managers, and analytics teams to build data services that are performant, secure, and scalable. This is an opportunity to influence the architecture of a modern SaaS data platform, designing distributed systems that process large-scale data while exposing reliable APIs and services to engineering teams and customer-facing applications. You'll work with technologies including Databricks, Apache Spark, Delta Lake, Azure Data Lake Storage, SQL Warehouse, and cloud-native Azure services.

If you're passionate about software engineering, distributed systems, cloud-native platforms, and building the infrastructure that powers data-driven products, we'd love to hear from you.

What you’ll get to do

• Design and develop production software in Python and C# that powers the data platform.
• Develop reusable platform libraries, frameworks, and SDKs used by other engineering teams.
• Design, build, and maintain REST APIs and backend services that power internal and customer-facing data products.
• Own software components from design through deployment, monitoring, and ongoing operational support.
• Build and operate production services with a focus on reliability, observability, performance, and scalability.
• Participate in architecture discussions and continuously improve the platform through automation and engineering best practices.
• Apply software engineering best practices including code reviews, automated testing, CI/CD, and clean architecture.
• Build scalable ingestion services, processing frameworks, and reusable data platform components.
• Develop reliable pipelines using Azure Data Lake Storage, Databricks, and SQL Warehouse to support analytics, reporting, machine learning, and customer-facing data products.
• Develop metadata-driven data processing frameworks that improve automation and reusability.
• Partner with Data Scientists to support AI agents.
• Optimize pipeline performance, storage, and compute costs across Azure and Databricks.
• Contribute to data governance initiatives including lineage, metadata management, documentation, and data quality standards.
• Support de-identification and privacy requirements for customer data across multiple regions.
• Collaborate with Product Management, Engineering, Analytics, and Data Science teams to deliver high-quality data solutions.
