It includes testing features and integrations, managing staging, pilot, and production environments, documenting implementation scopes and data flows, supporting migration and load testing, troubleshooting technical issues, and providing post-launch Tier 2/Tier 3 support until handoff to application support. The engineer coordinates with Product, Engineering, Services, Support, project managers, and client teams, and helps improve implementation methods and team practices. The position requires a bachelor’s degree in Computer Science, Engineering, or a related technical field, or an equivalent combination of education and experience. Candidates should have at least five years of software engineering experience, including at least two years in technical implementation and system integration and at least two years of programming experience. Experience in digital banking, FinTech, or regulated enterprise software is required. Travel is generally minimal, at 12 days or less per year, with approximately two team get-togethers annually.
