You should possess strong, production-tested experience in both Python and Java, along with a proactive approach to modern AI-assisted engineering workflows-specifically leveraging Claude Code (Anthropic's agentic CLI tool) and related AI tooling to accelerate development, refactoring, and code review cycles.Key Responsibilities
- API & Backend Engineering: Design, build, and maintain highly scalable, secure, and resilient RESTful and event-driven APIs using Python (e.g., FastAPI, Flask) and Java (e.g., Spring Boot, Micronaut).
- Full Stack Integration: Connect robust backend endpoints with responsive frontend interfaces and client-facing web applications.
- AI-Accelerated Development: Integrate agentic AI tooling-specifically Claude Code-into your daily developer workflows for code generation, test coverage expansion, refactoring, documentation, and automated debugging.
- Data & Cloud Integration: Interface with modern relational and NoSQL databases, message queues/streaming platforms (e.g., Apache Kafka, RabbitMQ), and cloud environments (AWS, Google Cloud Platform, or Azure).
- Client Collaboration: Work closely with cross-functional teams, architects, product managers, and client stakeholders to translate complex business needs into clean technical implementations.
- Best Practices & Quality: Enforce API design standards (OpenAPI/Swagger), automated CI/CD pipelines, containerization (Docker, Kubernetes), and security protocols (OAuth2, JWT).
Required Skills & Experience- Professional Experience: 4+ years of professional software development experience in full stack and API-centric application development.
- Dual-Stack Fluency: Deep, hands-on programming expertise in both Python and Java enterprise frameworks.
- Claude Code / Agentic AI Workflow: Proven familiarity and hands-on experience using Claude Code (Anthropic's terminal-based coding assistant) to plan, write, refactor, and review codebase changes.
- API Architecture: In-depth knowledge of API design paradigms (REST, GraphQL, or gRPC), microservices patterns, error handling, rate limiting, and API security.
- Database & Cloud Skills: Solid proficiency with SQL/NoSQL databases and core cloud services (AWS preferred).
- DevOps & Tooling: Strong familiarity with Git, Linux CLI environments, Docker, and standard CI/CD pipelines.
Preferred Qualifications- Experience in management/technology consulting or working with enterprise clients.
- Working knowledge of modern frontend frameworks (e.g., React, TypeScript).
- Experience with distributed streaming systems (e.g., Kafka) or orchestration frameworks.
- Familiarity with building LLM-integrated applications (e.g., RAG pipelines, function-calling architectures).
