Your contributions will drive business impact, enhance platform security and resiliency, and support developer self-service. You will help foster a culture of diversity, equity, inclusion, and respect while advancing modern engineering practices.

Job Responsibilities:

• Collaborate with technical teams, product partners, and stakeholders to deliver customer-facing capabilities and internal enablement
• Design, develop, and maintain secure, high-quality production Java services (APIs and supporting components), reviewing and debugging code
• Contribute to decisions influencing product design, API design, application functionality, and technical operations
• Build and integrate services supporting portal experiences such as API discovery, documentation delivery, onboarding flows, entitlements, analytics, and developer self-service
• Implement and advocate for security best practices, including secure coding, secrets handling, authentication/authorization, and data protection
• Participate in agile ceremonies and promote modern engineering practices (CI/CD, automated testing, trunk-based development, resiliency patterns)
• Add to the team culture of diversity, equity, inclusion, and respect
• Leverage enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards
• Apply knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation

Required Qualifications, Capabilities, and Skills:

• Strong proficiency with modern Java (e.g., Java 11/17+), concurrency fundamentals, and performance-aware coding
• Experience building services with Spring / Spring Boot, including dependency injection, configuration, and REST services
• Strong experience designing and implementing RESTful APIs, schema/versioning practices, and contract-first or OpenAPI-driven development
• Hands-on experience with secure coding and safe data handling
• Unit/integration testing (e.g., JUnit, Mockito) and ability to build effective automated test coverage
• Experience interacting with downstream services, troubleshooting integration issues, and designing for resiliency (timeouts, retries, circuit breakers)
• Practical experience with relational databases and SQL; familiarity with caching patterns is a plus
• Exposure to agile methodologies, CI/CD pipelines, and production support practices (monitoring, on-call readiness, post-incident reviews)
• Strong communication skills and ability to collaborate across functions
• Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, testing, troubleshooting, or documentation) with demonstrated ability to critically evaluate and validate AI-generated outputs
• Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations

Preferred Qualifications, Capabilities, and Skills:

• Experience with AWS services relevant to backend platforms (e.g., IAM, ECS/EKS, EC2, S3, RDS/Aurora, CloudWatch, API Gateway, Lambda)
• Familiarity with microservices, service decomposition, event-driven patterns, and domain-driven design
• Experience with containerization and orchestration tools such as Docker and Kubernetes
• Understanding of Infrastructure as Code tools (e.g., Terraform) and environment provisioning
• Experience with observability tools and concepts (logging, metrics, tracing, OpenTelemetry)
• Exposure to integrating AI capabilities (semantic search, retrieval-based Q&A, content summarization) with attention to quality, privacy, and governance
• Understanding of modern application infrastructure design and non-functional requirements (security, scalability, availability)
• Familiarity with caching technologies (e.g., Redis or in-memory caching patterns)
