Working with architects, data engineers, security, DevSecOps, product teams, and vendors, the developer incrementally refactors or replaces legacy functionality, responsibly integrates AI into business workflows, preserves essential business rules, reduces point-to-point dependencies, and delivers secure, maintainable AWS-based solutions.\nResponsibilities:\nAs a mid-level Software Developer, utilize AI engineering capabilities to help modernize a large-scale GrantSolutions application portfolio through phased, low-risk delivery. The developer will enhance and refactor legacy applications, build new cloud-hosted services using modern languages and frameworks, and develop production-ready AI capabilities that improve information access, automate workflows, and augment user decision-making. The developer will implement interoperability between modern, AI-enabled, and legacy capabilities through an integrated data layer. The role is primarily a software development position, with responsibility for application code, reusable data and AI services, APIs, events, transformation logic, automated tests, AI evaluation, monitoring, and production support.\nThe Software Developer will translate architecture and data-governance standards into working software. The developer will expose legacy capabilities safely, develop modern modules and microservices, establish consistent data contracts, and support synchronization and traceability across systems of record.
