Role Overview:
You’ll build both backend and frontend components of our platform, including the Admin Console, Client Integrations (MS Teams, Outlook, CRM, Enterprise System APIs), and Agent Management Tools powered by our proprietary HEART engine.
This role is ideal for engineers who are excited about merging enterprise SaaS engineering with AI agent innovation—from OpenAI Assistant integration to multi-agent orchestration and Retrieval-Augmented Generation (RAG) and much more. The role and capabilities grows with the technology and our pure imagination2execution at times.
Key Responsibilities:
• Build, scale, and maintain full-stack applications for AI-powered digital agents and customer-facing tools
• Develop user-facing components and APIs for the Admin Console and integrated enterprise touchpoints
• Implement and orchestrate GenAI pipelines using tools like OpenAI Assistants, prompt chains, and function calls
• Work with RAG frameworks to combine LLMs with external data sources (vector databases, structured data, etc.)
• Design and deploy multi-agent systems using frameworks such as Crew AI or custom orchestration stacks
• Collaborate with AI architects to create modular, scalable AI workflows for client-specific use cases
• Implement security, observability, and compliance best practices for production-grade AI systems
• Optimize system performance, LLM latency, and resource usage to meet enterprise-grade standards
• Contribute to DevOps practices, including CI/CD pipelines, containerization, and deployment automation
• Participate in sprint planning, architecture discussions, peer reviews, and code documentation
Required Qualifications:
• 3+ years of experience in full stack development (preferably B2B SaaS)
• Proficiency in TypeScript, React, Node.js, and modern web frameworks
• Strong Python development experience, particularly in AI and data-centric projects (Pandas, NumPy, TensorFlow, PyTorch, Keras, etc.)
• Hands-on experience working with OpenAI API, including prompt engineering and assistant-based applications
• Familiarity with multi-agent architectures and tools like Crew AI, LangGraph, or similar frameworks
• Experience building and integrating RAG pipelines, including external knowledge bases or vector stores
• Understanding of AI agent behavior, autonomy, and inter-agent collaboration
• Comfortable working with complex backend workflows, task queues, and secure enterprise integration
• Knowledge of authentication (OAuth, SSO), containerization (Docker, Kubernetes), and cloud platforms (Azure, etc.)
• Strong problem-solving, debugging, and optimization skills
Nice to Have:
• Experience integrating with Microsoft systems (Teams, Outlook, SharePoint, Graph API)
• Background in reinforcement learning, natural language processing, or conversational AI
