About the Opportunity

Dayforce is building a next-generation Agent Platform to power intelligent automation, AI-driven workflows, and tool-enabled execution across our product ecosystem.

We are seeking a Senior Software Developer to design and build core services that enable secure, scalable, and observable AI agent execution. This role focuses on deep technical implementation, platform reliability, and enabling engineering teams to successfully integrate with Agent Platform capabilities.

The ideal candidate is a hands-on software engineer who thrives in distributed systems environments and enjoys solving complex backend and infrastructure challenges.

Due to the nature of the work supporting the Government of Canada, candidates must meet applicable citizenship and security clearance requirements.

What You'll Get to Do

Core Engineering

• Design and implement production-grade backend services that support AI-driven workflows.
• Contribute to execution orchestration, task routing, and tool invocation systems.
• Develop stable, extensible, and well-documented APIs and service contracts.
• Implement secure authentication, authorization, and execution patterns.

Reliability & Observability

• Build systems with robust logging, metrics, and distributed tracing.
• Improve system resilience, fault tolerance, scalability, and performance.
• Participate in production readiness, monitoring, and incident response activities.

Platform Enablement

• Collaborate with Product and Engineering teams integrating with the Agent Platform.
• Provide technical guidance on integration patterns and engineering best practices.
• Contribute reusable infrastructure components, platform capabilities, and developer tooling.

Skills and Experience We Value

• 5–8+ years of experience building and operating distributed systems in production.
• Experience integrating large language models (LLMs) into applications or services.
• Strong backend development experience using TypeScript, C#, Go, or similar languages.
• Hands-on experience with containerized infrastructure, including Kubernetes.
• Strong understanding of secure service design and authentication patterns.
• Experience implementing observability practices, including logging, metrics, and tracing.
• Demonstrated ownership of features from design through production.

What Would Make You Stand Out

• Familiarity with worker-based architectures or execution isolation models.
• Experience contributing to internal platforms or shared infrastructure services.
• Experience optimizing performance and troubleshooting distributed systems.
• Experience collaborating with globally distributed engineering teams.
