Software Engineer (Full-Stack, .NET/React)
Location
Remote (US-based)
Overview
In the world of sports and digital media, athletes lead – and we build the platform that powers them. From NIL to endorsements, content campaigns to licensing deals, Opendorse is changing the game for over 140,000 athletes across every level of sport.
We’re looking for a full-stack engineer who’s passionate about writing clean, scalable code and wants their work to make a real difference. In this role, you’ll work across the stack to deliver fast, reliable experiences that help athletes and brands connect, collaborate, and win. You’ll build modern APIs, create responsive user interfaces, and contribute to a product that’s transforming athlete marketing.
This isn’t just another engineering job. You’ll have a voice, real ownership, and the chance to work on a product that’s reshaping how athletes maximize their name, image, and likeness.
What You’ll Do
- Build high-performance applications: Design, develop, and maintain scalable software that powers the Opendorse platform.
- Own backend services: Write clean, testable code in .NET to deliver reliable APIs and business logic.
- Craft modern interfaces: Use React and TypeScript to build engaging, responsive UIs that deliver a great user experience.
- Leverage AI development tools: Use AI-assisted workflows to accelerate development, improve quality, reduce repetitive work, and help shape how our engineering team builds software.
- Move data with confidence: Work with SQL Server to store, query, and manage data efficiently.
- Focus on quality: Write unit and integration tests to ensure our systems are resilient and maintainable.
- Collaborate to deliver: Work closely with product, design, and engineering teammates to ship features that matter.
- Drive technical growth: Contribute to architectural decisions, code quality initiatives, and performance improvements across the stack.
How We Build
We believe the future of software engineering includes thoughtful use of AI. Our team is actively experimenting with AI-assisted development workflows to improve speed, quality, learning, and impact. We’re looking for engineers who are energized by that evolution and want to help define what great AI-enabled engineering looks like in practice.
