• Develop and integrate AI/GenAI capabilities, including prompt design, LLM integration, RAG pipelines, embeddings/vector search, semantic search, classification, summarization, and AI-assisted communication workflows.
• Prototype, validate, and productionize AI-enabled features while considering latency, accuracy, cost monitoring, fallback design, and operational reliability.
• Design solutions for high availability, scalability, resiliency, observability, performance, security, privacy, and compliance needs.
• Support integrations with internal enterprise systems, eventing platforms, data providers, communication providers, and vendor-managed services.
• Troubleshoot and resolve complex production issues, including performance bottlenecks, integration failures, data issues, and system reliability concerns.
• Collaborate with architects, product owners, business stakeholders, development teams, and vendor teams to convert requirements into working solutions.
• Contribute to technical design, system documentation, code reviews, automated testing, CI/CD pipelines, release readiness, and production support practices.
• Ensure solutions align with enterprise engineering standards, security expectations, and application lifecycle best practices.
• Mentor developers through code-level guidance, design reviews, and engineering best practices while maintaining a focus on hands-on delivery.

• Bachelor's degree in Computer Science, Information Systems, Engineering, or a related field, or equivalent work experience.
• Minimum 8 years of experience in software engineering, application development, integration, and SDLC delivery.
• Strong hands-on software development experience, with a focus on coding, debugging, designing, and delivering working software.
• Minimum 8 years of hands-on Java backend development experience, including Spring Boot, REST APIs, microservices, and open-source technologies.
• Minimum 3 years of experience with event-driven systems, messaging, streaming integration, or notification platform capabilities.
• Hands-on experience with Apache Camel or equivalent enterprise integration frameworks.
• Minimum 4 years of experience with AWS or equivalent cloud services (e.g., EC2, S3, RDS, VPC, CloudFront, Lambda, EKS, ECS, API Gateway, DynamoDB, DocumentDB, AmazonMQ).
• Strong hands-on AI/GenAI implementation experience in enterprise or production-grade applications.
• Practical experience implementing AI capabilities such as LLM integration, prompt engineering, RAG embeddings/vector search, semantic search, classification, summarization, AI-assisted workflow automation, or decision-support capabilities.
• Understanding of responsible AI and secure AI engineering practices, including data privacy, access control, guardrails, evaluation, monitoring, and auditability.
• Experience with observability and analytics tools such as Dynatrace, ELK Stack, or CloudWatch.
• Experience working in agile delivery environments with CI/CD, automated testing, code quality, deployment readiness, and production support.
• Knowledge of software engineering best practices, including version control, software packaging, release management, automated testing, secure coding, and operational readiness.
• Strong analytical and problem-solving skills with the ability to diagnose complex technical issues independently.
• Self-motivated, collaborative, and able to communicate effectively with technical and non-technical stakeholders.

• Experience designing and developing enterprise notification, communication, customer messaging, content management, or eventing platform solutions.
• Experience with Twilio or similar communication/messaging platforms.
• Experience applying AI to communication use cases such as personalization, routing, prioritization, content quality checks, template assistance, intent classification, summarization, or operational anomaly detection.
• Experience with AI observability, LLMOps/MLOps practices, model/prompt evaluation, AI guardrails, and production monitoring of AI-enabled features.
