About the opportunity

The Dayforce Product Development team is looking for an experienced Software Developer to create the industry’s next generation Human Capital Management (HCM) solutions. 

What you’ll get to do

As a senior developer on our Workforce Management team, you will be working on our ground-breaking solution that helps companies increase their efficiencies through tracking time and attendance and intelligent scheduling of their employees. Your impact will be evident through your effective participation in the entire lifecycle of our software including design, analysis, prototyping, development, testing, deployment, and support of our products.

You will be conducting code reviews of peer work and mentoring other developers. 

If you are a technology enthusiast, have passion for creating great software, want to see your creation utilized by thousands of people all over the world, and possess the following qualifications, we want to talk to you. 

Skills and experience we value

Solid knowledge of object-oriented principles (SOLID) and experience applying them in practice using C#/.NET (5+ years), including async/await and LINQ. 

Experience with modern .NET (e.g., .NET 6/ 7/ 8) and the ability to modernize .NET Framework code where needed. 

Demonstrated experience building production UIs with the JavaScript stack, especially React and TypeScript (2–3+ years). 

Working knowledge of modern web technologies including: HTML5, CSS3, SVG, Web APIs, JSON, and REST (gRPC/GraphQL a plus).

Testing and quality focus: unit/integration/E2E tests (xUnit/NUnit/Jest/Playwright/Cypress) and code reviews. 

Security fundamentals: OWASP basics, authentication/authorization (OAuth2/OIDC), and handling of PII. 

AI-accelerated engineering: demonstrated use of AI developer tools (e.g., GitHub Copilot, Codeium, Sourcegraph Cody, etc.) to increase velocity and quality—such as generating unit tests, assisting refactors, drafting PR summaries/runbooks, or composing queries/migrations. Be prepared to discuss measurable impact (cycle time, PR throughput, defect rate, coverage, or MTTR).

Familiarity with feature flags/experimentation (e.g., LaunchDarkly) and trunk-based development. 

Accessibility (WCAG 2.1 AA) and internationalization/localization awareness. 

Workforce Management/HCM domain knowledge (time capture, complex pay rules, compliance, time-zone/DST edge cases). 

Experience integrating LLM capabilities into products (e.g., retrieval/RAG, prompt design, evaluation/guardrails) is a plus. 

Disciplined self-starter, capable of working independently as well as in close collaboration within an agile development team. 

Excellent communication and collaboration skills.
