• Implement configuration validation, versioning, auditing, rollback, backward compatibility, and error-handling capabilities.
• Develop high-quality, reusable, and maintainable software using Python and/or Java.
• Design SQL and NoSQL data models for storing, retrieving, auditing, and versioning business rules and system configurations.
• Build and integrate solutions using Amazon EKS, AWS Lambda, Amazon ECS, Amazon S3, Amazon RDS, and Amazon DynamoDB.
• Develop REST APIs, asynchronous services, batch-processing components, and event-based integrations.
• Implement automated unit, integration, component, and contract testing.
• Integrate application components with CI/CD pipelines and GitOps deployment workflows.
• Build, package, and deploy applications using Docker and Kubernetes.
• Implement application logging, monitoring, distributed tracing, dashboards, and alerting using Dynatrace.
• Troubleshoot production issues and perform root-cause analysis across application, integration, data, and infrastructure layers.
• Conduct code reviews and enforce engineering, security, performance, and maintainability standards.
• Collaborate with architects, product owners, quality analysts, data engineers, DevOps engineers, and other developers.
• Use Windsurf and other AI-assisted engineering tools to accelerate development, refactoring, automated testing, troubleshooting, and technical documentation.

Required Technical Skills

• Configuration-driven applications
• Configurable API and data-integration frameworks
• Template-based code-generation frameworks
• Parameterized and reusable services
• Strong experience designing and optimizing JSON-, YAML-, and XML-based configuration interpreters.
• Strong understanding of configuration schemas, validation, versioning, auditability, backward compatibility, and rollback.
• Strong knowledge of SQL and NoSQL database modeling.
• Experience designing data models for business rules, metadata, configuration versioning, and audit history.
• Hands-on experience with:
• Amazon EKS
• AWS Lambda
• Amazon ECS

Preferred Qualifications

• Experience developing high-volume, fault-tolerant, distributed platforms.
• Experience with Kafka schema management and serialization formats such as Avro, JSON, or Protobuf.
• Knowledge of data lineage, schema evolution, data contracts, and data-quality controls.
• Experience with infrastructure-as-code and deployment tools such as Terraform, Helm, Argo CD, or equivalent technologies.
• Familiarity with design patterns for retry management, dead-letter queues, idempotency, caching, and fault tolerance.
• Experience implementing secure APIs and cloud services using authentication, authorization, encryption, and secrets-management practices.
• AWS Developer, AWS Solutions Architect, Kubernetes, Java, or Python certifications are an advantage.

Key Competencies

• Strong software-design and problem-solving abilities.
• Ability to translate business requirements into configurable and reusable technical solutions.
• Strong understanding of scalable and resilient distributed-system design.
• Effective debugging and root-cause-analysis skills.
