We are seeking a Principal AI Platforms Architect to design, guide, and evolve the architecture of next-generation intelligent agentic systems. This role bridges high-level system design with hands-on AI engineering - ideal for someone who can envision complex AI-enabled ecosystems while still being comfortable prototyping or coding to validate ideas. You'll work across AI, data, product, and engineering teams to define scalable architectures for AI-driven applications, enabling the seamless integration of large language models (LLMs), data pipelines, and enterprise systems.

AI Architecture & Solution Design

• Define system architectures for AI and LLM-based solutions, ensuring scalability, low-latency inference, and modularity.
• Design Agentic AI solutions to optimize business workflow automation, including the use of memory, agentic reflection, and task planning.
• Design AI integration patterns, such as RAG, for model orchestration, context management, prompt orchestration, and external system connectivity.
• Establish architectural blueprints, design principles, and governance frameworks for model versioning, data lineage and responsible AI solutions across the organization.
• Architect polyglot model runtimes and hybrid pipelines (batch training + streaming inference) with attention to cost, latency, and risk.

Prototyping & Validation

• Develop minimal viable prototypes or proof-of-concepts to test model architectures, RAG flows, and agent orchestration.
• Evaluate emerging AI frameworks and tools (e.g., LangChain, LlamaIndex, LangGraph, Strands, Google ADK, Semantic Kernel) for suitability and integration.
• Develop solutions using the latest agentic orchestration engines, such as n8n, Retool, OpenAI Agentkit, Microsoft Copilot Studio, and AWS Flows.

Implementation management and support

• Support restructuring IT processes and organization to adopt new systems.
• Oversee system performance, observability, and governance as solutions transition from prototype to production using tools such as LangSmith, Prometheus, Grafana, Evidently, WhyLogs, and OpenTelemetry.
• Optimize the application development processes - define standards for versioning, testing, and monitoring of models and AI services (LLMOps).

Communication and Collaboration

• Craft compelling narratives for Agentic reimagination of businesses, translating complex ideas for both technical and non-technical audiences.
• Deliver impactful presentations, leading modules, presenting findings, and building consensus with clients.
• Build collaboration, mentor teams, and share knowledge to drive collective success - partner with product managers, data scientists, and engineers to translate business goals into robust AI system designs.
• Facilitate technical and strategic working sessions and workshops with both client and internal teams - provide technical direction and mentorship to engineering teams on architectural patterns, scalability, and best practices.
• Provide directions on key work items and feedback to other team members.

Team Management

• Manage junior team members by defining and organizing their "module", helping them structure their work and associated analyses.
• Mentor and coach junior team members by building mutual development agreements and manufacturing opportunities for them to grow and develop along explicitly defined objectives.
• Provide quality assurance oversight - Review junior team members' output for overall correctness, level of insight, clarity, etc.
• Promote an overall positive experience for junior staff
• Serve as a role model by actively demonstrating and living BCG's Culture and Values.

Innovation and Growth

• Stay ahead of the curve on new techniques in distributed AI systems, retrieval-augmented generation (RAG), retrieval/indexing strategies, and agent frameworks.
• Drive innovation, uncovering novel ideas and transformative solutions.
• Serve as the subject matter expert on LLM integration, agentic system design, and intelligent automation frameworks.
• Foster a growth mindset, continuously learning and applying new skills to grow your impact.
• Support business development through technical proposals with clear AI/ML technology choices and roadmaps.
• Manage mid-to-senior level client relationships autonomously.
