Job description

Java Developer needed for an ONSITE position in Brooklyn, OH for a contract role. Only LOCAL candidates will be considered.

Job Summary

We are seeking a Java Developer to design, build, enhance, and support secure, scalable enterprise applications for a financial services environment. This role will focus on backend development using Java, Spring Boot, REST APIs, Oracle Database, and microservices architecture. The ideal candidate is a hands-on engineer who can work independently on well-defined features, collaborate with business and technology stakeholders, and contribute to reliable, maintainable solutions that support critical business workflows. This position is well suited for a developer who has solid backend engineering experience, understands enterprise application delivery, and is comfortable working across the full software development lifecycle. Familiarity with Angular is a plus, especially for teams that occasionally support or coordinate with frontend application components.

Key Responsibilities

• Design, develop, test, and maintain Java-based applications and microservices using Spring Boot and related Spring frameworks.
• Build and enhance RESTful APIs that support enterprise business processes and service-to-service integrations.
• Develop backend business logic, data access layers, and integration components using Java, Spring Boot, and Oracle Database.
• Write clean, maintainable, secure, and testable code aligned with team standards and enterprise engineering practices.
• Work with Oracle SQL, database schemas, stored procedures, indexes, constraints, query optimization, and transaction handling to support data quality and performance.
• Participate in application design discussions, API contract definition, technical documentation, code reviews, and implementation planning.
• Troubleshoot application issues across development, test, and production environments, including root-cause analysis, defect resolution, and performance tuning.
• Support application reliability, availability, monitoring, logging, and operational readiness for financial services systems.
• Collaborate with product owners, business analysts, QA engineers, DevOps engineers, architects, and other developers to deliver business value through iterative development.
• Participate in Agile ceremonies such as sprint planning, daily standups, backlog refinement, reviews, and retrospectives.
• Contribute to continuous improvement by identifying opportunities to improve code quality, automation, performance, supportability, and delivery efficiency.
• Communicate technical concepts clearly to both technical and non-technical stakeholders.

Preferred Qualifications

• Familiarity with Angular or other modern frontend frameworks, with the ability to understand UI/API interactions and collaborate effectively with frontend developers.
• Experience in banking, lending, payments, risk, compliance, or broader financial services technology environments.
• Experience with Spring Security, OAuth/OIDC, JWT, API gateways, or enterprise authentication and authorization patterns.
• Experience with containerized or cloud-native deployment environments such as Kubernetes, GCP, or similar platforms.
• Familiarity with messaging or event-driven patterns using technologies such as Kafka, IBM MQ, or similar tools.
• Experience with observability tools such as Elastic, Grafana, AppDynamics, Dynatrace, or similar monitoring/logging platforms.
• Exposure to DevOps practices, automated deployment pipelines, environment configuration, and release management.
• Understanding of performance tuning for Java services, REST APIs, and Oracle SQL queries.
• Experience contributing to technical documentation, API specifications, operational runbooks, and production-support knowledge bases.
• Awareness of regulated-environment expectations, including auditability, traceability, access control, data protection, and change-management discipline.

The successful candidate should understand that financial services applications often support high-value business processes and sensitive customer or transactional data. This role requires an engineering mindset that prioritizes:

• Reliability: Building services that are stable, observable, and supportable in production.
• Performance: Designing APIs and database interactions that can scale with business needs.
• Security: Applying secure coding practices and supporting vulnerability remediation.
• Data integrity: Protecting accuracy, consistency, and completeness of financial and customer data.
• Regulatory awareness: Working carefully in environments where controls, auditability, and change discipline matter.
• Business collaboration: Partnering effectively with product owners, analysts, operations, risk, compliance, and technology teams.
• Ownership: Taking responsibility for assigned features from design through implementation, testing, deployment support, and issue resolution.
