Orlando, FL | Full-Time | 100% Onsite
Join an award-winning team! AutoPayPlus was named a 2026 Orlando Top Workplaces winner by Orlando Sentinel Media Group.
AutoPayPlus is looking for a Senior Software Engineer – Mobile & .NET who is comfortable working across the stack—not someone limited to just the mobile UI or just the backend.
Our applications support financial transactions and member experiences where performance, reliability, security, and accuracy matter. We're looking for an experienced developer who can step into our environment, contribute quickly, troubleshoot real production challenges, and help us continue improving the technology behind our products.
This is a hands-on development role. You'll work closely with a collaborative development team, Product, QA, and business stakeholders while having the opportunity to influence how our applications continue to evolve.
You'll have the opportunity to:
-
Develop and enhance mobile applications supporting both iOS and Android.
-
Build and maintain responsive web and mobile experiences using Angular and Ionic/Capacitor/Cordova.
-
Develop and support backend services and APIs using C# and .NET.
-
Build and maintain REST APIs using ASP.NET Web API and ASP.NET Core.
-
Work extensively with Microsoft SQL Server and T-SQL.
-
Create and maintain stored procedures, views, complex queries, and data-driven application functionality.
-
Troubleshoot application issues across mobile, web, backend, QA, staging, and production environments.
-
Integrate third-party APIs and enterprise systems.
-
Develop real-time functionality, notifications, alerts, and other member-facing features.
-
Support mobile releases through the Apple App Store and Google Play.
-
Participate in code reviews, architecture discussions, Agile/Scrum ceremonies, and continuous improvement initiatives.
-
Contribute to Git-based source control and CI/CD pipelines.
-
Help improve application performance, scalability, security, reliability, and overall member experience.

Strong professional C#/.NET development experience.

Hands-on experience building REST APIs using ASP.NET Web API and/or ASP.NET Core.

Both .NET Framework 4.x and modern .NET.

IIS-hosted applications and Microsoft enterprise environments.
-
WebSockets, SignalR, Firebase, or other real-time technologies.

APNs and Firebase Cloud Messaging.

Third-party API and enterprise system integrations.

Financial services, fintech, banking, payments, or other transaction-heavy applications.
Why This Role Is Different
This isn't a position where you'll spend your day working on one small piece of an application.
You'll have visibility across the mobile experience, APIs, backend services, databases, integrations, and production environment. We're looking for someone who enjoys understanding how the pieces connect, solving difficult problems, and taking ownership of solutions from development through deployment.
Because our technology supports financial services, the work you do directly contributes to the reliability and trust our members expect from AutoPayPlus.
