At Jack Henry, we’re more than a technology company; we’re a force for good in financial services. We’re redefining how community banks and credit unions connect with the people they serve. Our mission is rooted in people-inspired innovation, empowering financial institutions to deliver seamless, secure, and human-centered experiences. We deliver cutting-edge solutions that are paving the way for the next generation of digital banking and payments, but our true impact begins with our associates. If you're ready to help transform an industry and grow with a company that values purpose, collaboration, and excellence, then we’d love to meet you.

As part of the JH Integration development team, you will be at the center of Jack Henry's Technology Modernization Strategy. In your daily activities as a Senior C#/Go Software Engineer, you will work on a development team creating shared platform services using an innovative technology stack. You'll collaborate daily with Software Engineers, DevOps Engineers, Product Owners, and Business Analysts across the organization, leveraging modern development practices and tools—such as container orchestration platforms like Kubernetes, cloud providers like GCP, observability and monitoring solutions like Datadog or Honeycomb, and progressive delivery tools like Argo.

This position is ineligible for immigration sponsorship and support. Please do not apply if at any time you will need immigration support now or in the future (i.e., H-1B, STEM OPT Training Plans, etc.).

What you'll be responsible for:

  • Building, testing, deploying, maintaining, and scaling backend services in a microservices architecture using the C#/Go programming language in an agile development environment, running and leveraging services on a major cloud platform.

  • Working collaboratively to identify needs, prioritize and plan work, and develop solutions that keep pace with product development.

  • Gaining a deep and comprehensive understanding of specific banking-related domains your team owns and working with and understanding how changes in those domains impact products.

  • Participating with customer support teams to resolve or diagnose defects and issues.

  • Continually growing your technical skill set.

  • May perform other job duties as assigned.
