About the opportunity 

The Dayforce Tax and Payments (DTP+) Product Engineering team is building the industry's next generation of Tax and Financial Services — a cloud-native, microservices-based platform on Azure that is replacing a decade-old monolithic system and handling hundreds of billions of dollars in tax liability and fund movement annually.

This is not a role for someone planning to adopt AI tooling someday. We are looking for engineers who are already working AI-natively — developers who reach for Copilot, Claude, or an LLM API the same way they reach for a compiler. You use AI to write, review, test, and reason about code every day. That is the baseline. What we want to build on top of that baseline is deep platform engineering skill, strong fundamentals, and the kind of technical judgment that comes from having shipped real things.

As a Senior Software Developer on a DTP+ scrum team, you will design and deliver platform features across the Collections, Payments, Customer Profile, Agency Compliance, and eFile services. You will work directly with Architects, Product Managers, and peer developers to shape technically sound, well-engineered solutions for a platform that North American employers and regulators depend on.

If you are a senior or lead engineer who takes pride in clean code, thinks carefully about system design, and is genuinely excited about the shift to AI-augmented software delivery — we want to talk.

What you'll get to do

Design and deliver highly scalable, event-driven microservices features across the DTP+ platform — from data ingestion through fund movement and compliance filing

Work AI-natively every day — use AI coding tools (GitHub Copilot, Cursor, Windsurf, or equivalent) as a primary productivity layer for feature development, code review, and debugging

Integrate LLM APIs and AI patterns where they add genuine product value — including calling Azure OpenAI or equivalent APIs, building prompt chains, and applying RAG patterns to real features

Contribute to the team's AI practices — share what works, help teammates level up on AI-assisted testing and code review, and bring new patterns to the scrum team's workflow

Drive design and code reviews, ensuring solutions are clean, testable, performant, and consistent with platform conventions

Write high-quality unit, integration, and regression tests — including AI-generated test suites where appropriate

Mentor fellow developers on software engineering fundamentals, clean code principles, and AI-augmented development practices

Build working proof-of-concepts and make concrete technology recommendations to improve scalability, maintainability, and quality

Participate in Product discussions to advise on and influence the DTP+ roadmap

Take ownership of development initiatives end-to-end — design, implement, test, ship, and support

Skills and experience we value

AI-Native Development — Must Have

These are not aspirational. We expect candidates to demonstrate these in day-to-day engineering work:

Daily, hands-on use of AI coding tools — GitHub Copilot, Cursor, Windsurf, or equivalent — as a first-class part of your development workflow (code generation, refactoring, debugging, documentation)

Experience integrating LLM APIs (Azure OpenAI, OpenAI, Anthropic, or equivalent) into real software features in a product or professional context

Working knowledge of RAG design patterns and prompt engineering applied to actual software problems — not just familiarity from courses or demos

Familiarity with tool-calling and MCP (Model Context Protocol) integration patterns and how agentic workflows compose with existing backend services

AI-assisted testing practices — using AI for test case generation, PR review automation, or debugging complex runtime behavior

Software Engineering Fundamentals

Strong object-oriented design and programming skills in C# / .NET / .NET Core (primary) or Java; deep knowledge of SOLID principles, clean code, and maintainable system design

Proficiency with SQL on modern relational databases; ability to write performant queries, design schemas, and reason about data integrity

Hands-on experience applying design patterns, writing comprehensive unit and integration tests, and profiling / optimizing performance

Strong understanding of microservices architecture — service boundaries, inter-service communication, data ownership, eventual consistency

Cloud, Infrastructure, and Platform

Production experience building and deploying services on Microsoft Azure — including Azure Kubernetes Service (AKS), Azure Service Bus, Azure DevOps, Azure Functions, or equivalent services

Hands-on experience with Apache Kafka or Confluent Cloud for event-driven, asynchronous messaging in a distributed system

Docker and Kubernetes — containerizing services, writing Helm charts or Kubernetes manifests, and deploying to managed clusters

NoSQL databases — production experience with MongoDB, Azure Cosmos DB, or equivalent; understanding of document modeling, indexing, and consistency trade-offs

CI/CD pipelines as code using Azure DevOps, GitHub Actions, or equivalent — automated builds, tests, deployments, and quality gates

Experience designing and implementing REST and/or gRPC APIs with appropriate authentication, versioning, and contract hygiene

Delivery and Collaboration

Strong agile delivery skills — active contributor in sprint ceremonies, owns stories end-to-end, flags blockers early

Excellent communication skills — able to explain technical decisions clearly to both engineers and non-engineers

Disciplined self-starter who works effectively independently and within a close-knit scrum team

Strong analytical skills and a systematic, evidence-driven approach to problem-solving

Education

Bachelor's or Master's degree in Computer Science, Software Engineering, or a related technical field (or equivalent practical experience)

What would make you really stand out

Frontend experience with Angular, React, or Node.js

GraphQL API design and implementation

gRPC and protobuf schema design

ElasticSearch / OpenSearch for indexing and query

Behavior-driven testing with SpecFlow or similar BDD frameworks

Experience with NuGet packaging and library distribution

Fintech, payroll tax, or financial services domain experience

Why This Role

You will work on real infrastructure at scale — the DTP+ platform processes tax liability and fund movement for thousands of North American employers

The team is actively transitioning to AI-native engineering — your experience will accelerate the team, not just support it

Greenfield microservices on Azure, Kafka, and Kubernetes — the architecture is modern and the decisions are yours to influence

Senior engineers here have a voice in product direction, architecture, and engineering culture
