Software Engineer III - Java Backend

BOK Financial is a stable and financially strong organization that provides excellent training and development to support building the long term careers of employees. In this role, you’ll be a hands-on technical leader, mentoring the project team and collaborating with the Solution Architect to determine project architecture while developing Java Spring Boot microservices and RESTful APIs on AWS.

Responsibilities:

• Mentor the project team, share knowledge, and collaborate with the Solution Architect to determine project architecture
• Lead in developing projects, promoting best programming practices, and have influence over developers
• Provide application support, develop and document applications, and maintain application documentation and configuration
• Design & Build: Architect and implement Spring Boot microservices and RESTful APIs with best practices for domain-drive design, scalability, reliability, and maintainability
• Deliver features using event-driven architecture (Kafka, SNS/SQS/Kinesis), including publish/subscribe patterns, idempotency, retries, and error handling
• Model schemas and access patterns for SQL Server, PostgreSQL, MongoDB, and Redis; optimize for correctness, performance, and cost
• Develop using AI assisted- workflows with tools such as GitHub Copilot, Amazon Q, and Claude to accelerate coding, refactoring, documentation, and test generation
• Leverage agentic patterns for multistep tasks such as feature scaffolding, modernization, dependency analysis, and CI/CD interactions—with appropriate human-in-the-loop (HITL) controls
• Apply AI-assisted- PR review and security scanning, validating suggestions with engineering judgment and secure by design principles
• Continuously evaluate and improve how AI tools are used across the SDLC to increase throughput, quality, and developer experience
• Own testing strategy—unit, integration, and contract tests—while enforcing CI quality gates
• Help shape next generation- pipelines as we transition to AWS EKS
• Instrument services using New Relic; define SLIs/SLOs and participate in a minimal on-call rotation
• Follow secure coding practices and remediate findings; PCI & SOX awareness is helpful
• Lead design reviews, mentor peers, and guide pull requests with a high bar for craftsmanship
• Practice build-it/run-it ownership from development through production

Requirements:

• 5–8+ years of software engineering, with 3–5+ years designing and building secure Java Spring Boot microservices and RESTful APIs
• Production experience on AWS (compute, messaging, storage), event-driven patterns (Kafka, SNS/SQS/Kinesis), and container technologies (Docker, Kubernetes)
• Proficiency with SQL Server or PostgreSQL
• Strong test discipline (unit/integration/contract), CI/CD pipelines, and code review excellence
• Experience with observability tools (New Relic, Datadog, Splunk, etc.) and incident response
• This level of knowledge is normally acquired through the completion of a bachelor's degree in a technology field and/or 8+ years of related experience
• Technology certifications are preferred
• It is also preferred that the candidate have Banking and Financial Service experience
• Securing APIs with Spring Security and OKTA
• Familiarity with AI-assisted development tools (GitHub Copilot, Amazon Q) and DevSecOps practices
• Experience building APIs integrated with Kong API Gateway, Apigee, or similar API Gateway
• Experience with MongoDB, Redis, or similar NoSQL technology
• Experience building services deployed to Tomcat, Jetty, or similar Java Servlet containers
• Infrastructure-as-Code (Terraform/CDK), containers/orchestration (EKS/ECS), or serverless (Lambda) experience
• Experience with schema registries, CDC, or stream processing
• PCI & SOX awareness
