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.

We are seeking a Senior Frontend JavaScript Engineer to help shape and scale Jack Henry's developer experience through our open banking platform. This role will play a critical part in building and maintaining jackhenry.dev, the public-facing developer portal that enables fintech partners to seamlessly integrate with Jack Henry. As the gateway to our open platform, this site is essential to our innovation strategy; its performance, reliability, and usability directly impact our ability to deliver a world-class developer experience. Our team is highly distributed, meaning you will work with kind, talented engineers from across various locations within the US.

This position can be based out of any Jack Henry office or work remotely from any US location, with the exception of California. May require occasional travel, up to 5% for meetings, trainings, or conferences. All positions, regardless of location, may require an on-site interview or in-person onboarding requirement to verify your identity.

What you'll be responsible for:

• Develop Jack Henry Developer Relations Portal features using software engineering best practices and company engineering standards.
• Take the lead on new feature development.
• Display foresight when planning and coordinating projects so that the work can be broken into smaller pieces for the rest of the team.
• Apply knowledge of reliability, scaling, quality, and performance during development.
• Represent your team throughout the technical decision-making process (e.g., discovery meetings).
• Consistently debug release pipeline and production service issues.
• May perform other job duties as assigned.

What you'll need to have:

• Minimum 6 years of experience in JavaScript or TypeScript programming.
• Strong understanding and demonstrated experience in developing responsive web apps.

What would be nice for you to have:

• Bachelor's degree in Computer Science.
• Previous experience developing technical documentation for engineers or developers.
• Proficiency with Web Components.
• Familiarity with Polymer or Lit.
• Solid understanding of security, API design, design patterns, and browser environment.
• Experience with front-end build systems such as webpack or rollup.
• Experience with Continuous Integration/Continuous Deployment (CI/CD) systems.
• Experience tracing a request through the network stack.
• Experience with SSOs, Plugins, or APIs.
• Experience implementing OAuth2/OpenID Connect.
• Experience supporting an application in production.

If you got this far, we hope you're feeling excited about this opportunity. Even if you don't feel you meet every single requirement on this posting, we still encourage you to apply. We're looking for passionate, driven individuals who align with our mission and can bring unique perspectives to our team.
