About The Position

Help modernize and scale the workflow platform behind Dayforce. We’re looking for a Senior Software Developer to join the Dayforce Platform Extensibility team and help evolve one of the most critical systems in Dayforce: Workflow. Our mission is to build scalable, extensible platform capabilities that reduce duplication and enable teams to move faster. At the heart of what we build is the Dayforce Workflow platform — a scalable, rule-based workflow orchestration engine powering employee lifecycle processes across a multi-tenant SaaS platform used by millions globally. We’re evolving Workflow into a reusable platform service with extensible APIs that support workflow capabilities across multiple Dayforce domains. As part of that evolution, we’re also investing in AI-enabled orchestration and intelligent automation experiences integrated directly into the platform. This is a platform engineering role focused on solving complex challenges at enterprise scale — evolving foundational systems, building extensible platform capabilities, and shaping the future of workflow orchestration across Dayforce. This is a full-stack role with a strong backend focus, where the most impactful work involves distributed systems, platform architecture, scalability, and backend engineering.

Requirements

Hands-on experience building or prototyping AI-enabled applications, agents, or orchestration workflows using LLMs and modern AI frameworks
Experience using AI-assisted engineering tools such as GitHub Copilot, Cursor, Claude Code, or equivalent as part of day-to-day development workflows as a practical force multiplier to teams
Strong experience building and maintaining production-grade enterprise applications with C#/.NET
Experience designing scalable backend services, extensible APIs, and reusable platform capabilities
Strong SQL Server expertise, including performance tuning, query optimization, concurrency, and troubleshooting at scale
Experience building distributed, high-volume systems with a focus on scalability, reliability, and performance
Practical experience with Azure and modern cloud development patterns
Ability to communicate with clarity across all levels — from technical design discussions with engineers to translating platform strategy and tradeoffs for leadership
Strong problem-solving and debugging skills across backend systems, distributed services, and platform infrastructure
Experience with modern development practices, CI/CD workflows, observability, structured logging, and operational reliability
Strong engineering judgment — balancing scalability, maintainability, platform evolution, and pragmatic delivery

Responsibilities

Own and evolve core capabilities within the Dayforce Workflow platform
Contribute to AI-enabled orchestration and intelligent automation initiatives, leveraging AI as a force multiplier to evolve workflow capabilities and developer productivity across Dayforce
Design and build scalable backend services, extensible APIs, and orchestration capabilities
Improve the scalability, reliability, and performance of high-volume workflow systems
Drive technical design, engineering standards, and operational excellence through modern development practices, observability, maintainability, and platform-focused architecture
Mentor teammates, contribute to technical leadership, and help raise the engineering bar across the team
