• Define system integration patterns, data flows, APIs, and microservice interactions.
• Prepare technical architecture documents, sequence diagrams, and high/low‑level designs (HLD/LLD).
• Evaluate and recommend appropriate frameworks, technologies, and tools.
• Review code and designs to ensure alignment with best practices, performance, and security standards.
• Provide guidance to development teams during implementation and support in resolving technical roadblocks.
• Ensure solutions are cloud‑ready and scalable (AWS).

Must Have

• Experience: Minimum 10+ years of experience in enterprise software development and architecture.
• Tech Stack: Deep expertise in Java (8/11/17+), Spring Boot, and REST APIs.
• Solid experience with microservices architecture, event‑driven systems, and containerization (Docker/Kubernetes).
• Hands‑on experience designing solutions for cloud environments (preferably AWS).
• Architecture Skills: Proficient in creating HLD/LLD, sequence diagrams, and architectural documentation.
• Experience with integration patterns (e.g., API Gateway, message brokers like Kafka or RabbitMQ).
• DevOps & Tools: Familiarity with CI/CD pipelines, infrastructure as code, observability tools, and service mesh concepts.
• Soft Skills: Strong communication and stakeholder management abilities.
• Proven track record of working with cross‑functional teams in agile or hybrid environments.
• Excellent problem‑solving, critical thinking, and decision‑making skills.
