Position Summary

OneSource Virtual is seeking an Associate Full Stack Developer to join our product engineering team. This is an entry-level role designed for a recent college graduate who is eager to grow quickly in a high-velocity, AI-assisted development environment. You will work across the full stack — C#/.NET services, React UI, and SQL — on platforms that process over $200 billion in compliant payroll and tax payments annually.

The ideal candidate is technically curious, comfortable using AI tools in their daily development workflow, and eager to be coached toward independent, high-quality delivery. You do not need to know everything — you need to learn fast, ask good questions, and care about the quality of your work.

Responsibilities

Development

• Build and maintain features across the full stack: C#/.NET backend services, React front-end components, and SQL data access layers
• Write clean, unit-tested code with a low defect rate and accept feedback constructively to improve quality over time
• Execute assigned user stories with light supervision, asking clear questions early to avoid rework
• Participate actively in sprint ceremonies — standups, backlog grooming, story breakdown, and retrospectives
• Learn and apply OSV’s coding standards, architectural patterns, and CI/CD practices
• Fix defects as they arise throughout the development cycle
