People First is looking for a Core Systems Developer to join our IT team! This individual is responsible for driving digital transformation at a $1 Billion Credit Union by designing and deploying scalable technical solutions that modernize the Corelation Keystone core banking architecture. This role is a hybrid of deep-dive backend engineering and modern UI development. You will innovate by orchestrating a "modern wrapper" strategy—using component-based JavaScript frameworks (e.g., React, Vue, Angular) to encapsulate legacy core interfaces. Additionally, you will engineer robust Java batch processes for high-volume transaction handling and implement Azure cloud-native solutions (AI/Data) to extend our financial ecosystem.

Essential Duties and Responsibilities: 

• Legacy-to-Modern Bridge: Design and implement user interfaces using modern component-based JavaScript frameworks (e.g., React, Vue, Angular) to "wrap" and extend the core system’s legacy Ext JS environment.
• Workflow Optimization: Bridge the gap between legacy DOM elements and modern web standards to create responsive, seamless teller workflows that reduce manual data entry and error rates.
• Batch Processing: Develop, package, and deploy Java-based batch processes and microservices to handle high-volume transaction processing and complex data transformations within the Corelation Keystone environment.
• System Analysis: Analyze core system configurations, schema definitions, and dependency maps to ensure custom code interacts safely and seamlessly with the financial system of record.
• Hybrid Cloud Logic: Architect secure integrations using Azure (or AWS) serverless functions and logic apps to connect the on-premises core banking system with third-party fintech solutions.
• API Orchestration: Engineer and maintain secure RESTful API endpoints to orchestrate data flow between disparate systems.
• AI & Data: Leverage Azure AI/Document Intelligence to extract value from documents and write efficient SQL queries to support downstream analytics.
• CI/CD Pipelines: Implement and manage automated deployment pipelines to streamline the promotion of code from development to production, ensuring rapid and safe delivery of features.
• Code Quality: Adhere to strict software engineering best practices, including version control (Git), unit testing, and peer code reviews, to ensure reliability in a production financial environment.
• Technical Documentation: Maintain comprehensive technical documentation for codebases, API specifications, and system architecture diagrams to support audit and compliance requirements.
• Business Logic: Utilize the Microsoft Power Platform (Power Automate, Power Apps) to digitize manual business processes, creating automated triggers and workflows where full custom code is not required.

Benefits:

• Excellent medical, dental, and vision plans
• Health reimbursement account
• Flexible Spending and Dependent Care Accounts
• Group Term Life Insurance
• Short-Term and Long-Term Disability
• Paid time off

• Must currently reside in Pennsylvania or be willing to relocate to Pennsylvania before starting employment.
• High School diploma or equivalent.
• 3–5 years of professional software engineering experience, with a specific focus on hybrid application architectures.
• Experience working within highly regulated industries (Banking, Healthcare, Insurance). Specific familiarity with credit union core platforms (Corelation Keystone, Symitar, or Jack Henry) is a significant plus.
• Demonstrated ability to take a business requirement from concept to deployment with minimal supervision. Experience working in an Agile/Scrum environment and participating in code reviews.
• Prior experience with Microsoft Power Platform (Preferred).
• Modern JavaScript: Proficiency in modern ECMAScript (ES6+) and component-based frameworks (React, Vue, or Angular) is required.
• Legacy Integration: Ability to read, debug, and "wrap" legacy Ext JS (3.x) code. You do not need to be an Ext JS expert, but you must be comfortable working within a legacy DOM environment to build modern extensions.
• UI/UX Standards: Experience building responsive, user-centric interfaces that simplify complex data entry workflows.
• Java Development: Strong grasp of Java Object-Oriented Programming (OOP). Experience writing, compiling, and deploying JAR files for batch processing is essential.
• API Architecture: Demonstrated experience designing and consuming RESTful APIs (JSON) and SOAP (XML) web services to orchestrate data between on-premises systems and the cloud.
• SQL & Data: Intermediate to Advanced SQL skills (DB2 familiarity is a strong plus) for writing complex queries, data analysis, and validation.
• Azure or AWS Cloud Ecosystem: Operational knowledge of Microsoft Azure (or AWS), with specific focus on Serverless Functions (for middleware logic), Logic Apps, and API Management.
• AI & Data Services: Familiarity with implementing cloud-native AI solutions (e.g., Azure AI, Document Intelligence) to automate manual data extraction.
• DevOps & CI/CD: Proficient with source control (Git) and automated deployment pipelines (Azure DevOps, Jenkins, or GitHub Actions) to manage code lifecycles safely.
• Low-Code Solutions: Experience designing workflows in Microsoft Power Automate and building interfaces in Power Apps to solve rapid-turnaround business problems.
