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. Design and implement production-grade backend services that support AI-driven workflows.

Improve system resilience, fault tolerance, scalability, and performance. Provide technical guidance on integration patterns and engineering best practices. Contribute reusable infrastructure components, platform capabilities, and developer tooling.



5–8+ years of experience building and operating distributed systems in production.

Experience integrating large language models (LLMs) into applications or services. Solid backend development experience using TypeScript, C#, Go, or similar languages. Familiarity with worker-based architectures or execution isolation models.

The final compensation offered may vary based on a variety of factors, including bonuses and/or incentives, or a candidate’s experience, skills, budget and location. Proficiency in English is required for this position as this role will regularly interact with English-speaking stakeholders, co-workers, managers and/or clients across the world. Further, our back office support teams, including but not limited to Human Resources, are primarily English speaking.

Employees need to be able to communicate with these departments in English to appropriately administer their business relationship. Due to the significant high volume of interactions with these English-speaking co-workers, managers, stakeholders and/or clients, which is inherent to this position, it is not possible to reorganize the company's activities to avoid this requirement. #
