Lead Developer - AI Platform Engineering

  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 Lead Developer to drive the design, implementation, and technical direction of the foundational infrastructure enabling secure, scalable, and observable AI agent execution across Dayforce systems. This role partners closely with the Agent Platform Technical Lead and AI Platform Development Leader and serves as a senior technical driver within the team. The ideal candidate brings deep distributed systems expertise, strong architectural judgment, and experience leading complex engineering initiatives in production-scale environments. What you'll get to do Technical Leadership Lead the design and implementation of core Agent Platform components, including execution orchestration and tool invocation frameworks Drive architectural decisions impacting cross-product AI integration Establish and uphold reliability, observability, scalability, and performance standards Define best practices for secure agent execution and service-to-service communication Platform Engineering Build secure, scalable backend services enabling AI-driven workflows Design APIs and service contracts supporting extensible platform capabilities Implement authentication, authorization, and secure system design patterns Contribute to infrastructure design leveraging containerized environments (e.g., Kubernetes) Cross-Team Impact Collaborate with multiple engineering teams to enable adoption of Agent Platform capabilities Identify architectural risks and proactively drive mitigation strategies Mentor and guide engineers integrating with or extending the platform Raise engineering standards through code quality, design rigor, and documentation Skills and experience we value 8+ years of experience building and operating distributed systems in production environments Strong backend engineering expertise (TypeScript, C#, Go, Java, or similar) Experience integrating large language models (LLMs) into production systems Proven experience designing APIs, service contracts, and scalable microservices architectures Hands-on experience with containerized and cloud-native infrastructure (e.g., Kubernetes) Strong understanding of authentication, authorization, and secure system design Experience implementing production-grade observability (logging, metrics, tracing) Demonstrated ability to lead complex technical initiatives with high autonomy Experience working with globally distributed teams and leading through asynchronous communication. What would make you really stand out Background in workflow orchestration, event-driven architectures, or DAG-based systems Experience building internal developer platforms or reusable infrastructure services Familiarity with execution isolation, sandboxing, or worker-based architectures Experience influencing architectural standards across multiple engineering teams Leadership Profile The ideal candidate: Operates effectively in fast-evolving technical environments Demonstrates strong architectural thinking and long-term systems design perspective Takes ownership of end-to-end system quality and platform health Communicates complex technical concepts clearly to engineering and leadership audiences Elevates team capability through mentorship and thoughtful technical direction Why This Role Matters The Agent Platform will serve as a foundational capability within Dayforce, enabling AI-powered features across multiple product domains. As a Lead Developer, you will directly influence how intelligent automation and AI workflows are architected, secured, and scaled across the organization. This is an opportunity to shape long-term platform architecture within a rapidly growing AI engineering organization and to lead the development of systems that will power the next generation of Dayforce intelligence.
