Senior Full Stack Java Developer Jobs in Middlefield, OH

Description

Position Overview The Software Engineer Lead is responsible for leading the development and support of software solutions that enable the Lending Digital Payment Platform. This role owns the Business Rules Engine (BRE) rules lifecycle and delivers Java/Spring Boot APIs that integrate decisioning with enterprise data sources. The position partners with product, architecture, engineering, QA, and operations to deliver secure, resilient, and maintainable services; provides technical guidance to peers; and drives engineering craftsmanship through standards, code/rule reviews, testing discipline, and modern delivery practices. Primary Responsibilities 1) Business Rules Engineering (BRE) Ownership • Own the BRE rule portfolio for the Lending Digital Payment Platform, including rule sets supporting payment eligibility, validation, and execution decisioning. • Elicit, clarify, and translate business policies into executable rules (decision tables/decision services/rule flows as applicable) with clear traceability back to requirements. • Design rule structures for readability, reuse, and safe change (naming conventions, modularization, versioning strategy, and deprecation approach). • Implement and maintain automated and repeatable rule testing (unit-level rule scenarios, regression suites, and test data management). • Review, validate, and approve rule changes through peer review; ensure changes include evidence (test results) and meet governance expectations. • Plan and execute safe promotion of rule assets across environments, including rollback strategy and release documentation. • Troubleshoot rule outcomes and production issues by analyzing inputs, execution traces, and downstream effects; drive root-cause resolution and preventative improvements. 2) API Engineering (Java / Spring Boot) • Design and implement RESTful APIs in Java and Spring Boot that expose platform capabilities and integrate with BRE decisioning. • Define and maintain API contracts (OpenAPI/Swagger where applicable), validate inputs, and implement consistent error handling and response semantics. • Implement service-layer logic that correctly orchestrates BRE calls, data access, and downstream integrations. • Ensure APIs meet non-functional requirements: performance, resiliency, observability, security, and maintainability. • Conduct code reviews and enforce coding standards; mentor engineers on design patterns, testing practices, and troubleshooting techniques. • Support deployments and production operations: diagnose incidents, fix defects, and deliver improvements that reduce repeat incidents. 3) Data Access (MySQL and Oracle) • Build and maintain data access layers for MySQL and Oracle using appropriate frameworks and patterns (JDBC/JPA as applicable). • Write and optimize SQL for correctness and performance; partner with data teams on indexing, query tuning, and schema change coordination. • Ensure secure data handling (least privilege, parameterized queries, secrets management) and adherence to data governance controls. • Implement reliable transaction management and error recovery strategies for database interactions. 4) Quality Ownership (Quality-First Engineering) • Set clear quality expectations for deliverables, including Definition of Done criteria for code, rules, tests, and documentation. • Drive a test strategy that includes unit tests, rule-level scenario testing, integration tests, and regression coverage appropriate to change risk. • Integrate automated tests into CI/CD pipelines with quality gates (for example: required test pass status, static analysis, and dependency vulnerability checks as applicable). • Reduce defect leakage by enforcing peer review standards, strengthening automated coverage, and using root-cause analysis to prevent recurrence. • Partner with Quality Engineering and Operations to improve release readiness, validation practices, and production support runbooks. • Monitor and improve operational quality signals (stability, incident trends, recurring defects) and prioritize corrective actions. 5) Technical Leadership & Delivery • Lead technical execution for complex platform features by breaking down work, aligning dependencies, and guiding implementation across the stack. • Drive end-to-end delivery: build, test, release, and support while balancing speed, quality, and risk controls. • Create and maintain technical documentation (runbooks, deployment notes, operational procedures, and decision logs as needed). • Improve engineering practices: CI/CD health, automated testing coverage, code quality gates, and release readiness checks. • Collaborate effectively with product owners, business analysts, SRE/ops, QA, and partner teams to deliver integrated outcomes.
