Solutioning & Architecture
- Solutioning & Architecture Design
- end-to-end AI solutions spanning Generative AI (RAG, CAG, GraphRAG, fine-tuning, model distillation) and agentic AI (tool-using agents, multi-agent orchestration, MCP-based integrations)
- Architect across all major hyperscaler AI stacks — AWS (Bedrock, SageMaker, Q), Microsoft Azure (Azure AI Foundry, Azure OpenAI), and Google Cloud (Vertex AI, Gemini) — and recommend the right platform per workload rather than defaulting to a single provider
- Architect sovereign / on-premise AI solutions using stacks such as NVIDIA AI Enterprise (NIM, NeMo, Blueprints), Dell AI Factory, HPE Private Cloud AI, Red Hat OpenShift AI, Run:ai, and open-source model serving (vLLM, TGI, Ollama) — for clients with data residency, regulatory, IP, or air-gapped requirements
Prototyping & Development
- Rapid Prototyping
- Build working prototypes — not just slides.
- Translate client problem statements into functional demos and pilots in days, not months.
- Stand up RAG, CAG, and agentic workflows quickly using frameworks such as LangChain / LangGraph, LlamaIndex, CrewAI, AutoGen, Semantic Kernel, and MCP-compliant agent toolchains.
- Integrate vector stores (Pinecone, Weaviate, Milvus, Chroma, pgvector, OpenSearch), graph stores (Neo4j, Neptune), and hybrid retrieval pipelines as the use case demands.
- Run rigorous, repeatable evals on prototypes (groundedness, faithfulness, latency, cost-per-task, tool-use accuracy) so recommendations are evidence-based.
Engineering & Modernization
- AI-Native Engineering & Modernization
- Lead solutioning for AI-native software engineering engagements: AI-assisted development, code refactoring at scale, tech debt burndown, legacy modernization, test generation, and documentation regeneration.
- Architect Secure SDLC (SSDLC) practices into every AI-built or AI-assisted codebase — threat modeling, SAST/DAST integration, SBOM generation, dependency hygiene, secrets management, and supply-chain security.
- Advises clients on integrating AI coding agents (Claude Code, Cursor, GitHub Copilot Workspace, Devin, and others) into their existing SDLC and DevSecOps toolchains without compromising guardrails.
- Define MLOps / LLMOps / AgentOps patterns: model and prompt versioning, evaluation pipelines, observability (traces, token usage, drift), guardrails, and human-in-the-loop review.
Security & Compliance
- AI Security
- Conduct AI-specific threat modeling for every solution — covering adversarial inputs, prompt injection, jailbreaking, model inversion, training data extraction, and indirect injection via tool outputs or retrieved documents — and translate findings into concrete mitigations in the architecture.
- Design multi-layer guardrail architectures: input sanitization and intent classification, output filtering (PII redaction, toxicity screening, factual grounding checks), content safety policies, and fallback / refusal handling — covering both hosted API models and self-hosted open-weight deployments.
- Maintain end-to-end AI supply chain security: vet third-party model weights and datasets for backdoors or poisoning, validate fine-tuned model integrity, enforce cryptographic signing of model artifacts, and apply model cards and datasheets as governance artifacts.
- Align AI solutions to applicable compliance frameworks — NIST AI RMF, OWASP LLM Top 10, ISO/IEC 42001, EU AI Act, and relevant sector-specific regulations — and produce the risk documentation, impact assessments, and audit trails clients need to satisfy internal governance and external regulators.
Client Engagement & Enablement
- Client Engagement & Enablement
- Serve as the senior technical voice in client conversations — from executive briefings through deep technical design sessions.
- Partner with sales, delivery, and practice leadership to scope statements of work, estimate effort, and de-risk delivery.
- Mentor architects, engineers, and consultants across the broader AI practice; raise the technical bar through code reviews, internal enablement, and reusable assets.
- Stay ahead of the field — evaluate emerging models, frameworks, and protocols (e.g., MCP, A2A, ACP, new agent frameworks, new sovereign AI stacks) and bring well-reasoned points of view back to the practice.
Qualifications
- 8+ years of progressive experience in software engineering, solutions / Enterprise architecture, or applied AI/ML, with at least 2+ years in a hands-on Generative AI or agentic AI role.
- Demonstrated ability to rapidly prototype AI solutions and ship working code — not just designs or documents.
- Deep, hands-on experience with at least one of the three major hyperscaler AI platforms (AWS, Azure, GCP) and a working understanding of the second and third.
- Production experience designing and shipping RAG and/or agentic systems, including practical familiarity with chunking strategies, embedding model selection, retrieval evaluation, and orchestration patterns.
- Working knowledge of MCP (Model Context Protocol) and modern agent-tool integration patterns; ability to design MCP servers and clients, and to reason about when MCP is the right abstraction versus alternatives.
- Strong understanding of CAG (Cache-Augmented Generation), RAG variants (naive, hybrid, GraphRAG, agentic RAG), and the trade-offs between each.
- Proficiency in Python; comfort in at least one additional language (TypeScript/JavaScript, Go, Java, or C#).
- Experience integrating with enterprise systems: REST/GraphQL APIs, event streams (Kafka, EventBridge), identity (OIDC, SAML, OAuth2), and enterprise data platforms (Snowflake, Databricks, Fabric, BigQuery).
- Excellent written and verbal communication; able to move fluidly between executive narrative and engineering whiteboard.
- Foundational fluency in AI security concepts: able to identify and articulate risks such as prompt injection, data poisoning, model extraction, and inference-time attacks, and to reason about appropriate mitigations for each in the context of a given architecture and risk tolerance.
Preferred Skills
- Software development background with real production experience across the SDLC and Secure SDLC (SSDLC) — including CI/CD, infrastructure as code (Terraform, Pulumi, Bicep), containers and Kubernetes, and DevSecOps tooling.
- Experience leading code refactoring, technical debt remediation, and legacy modernization programs — ideally with AI-assisted approaches.
- Experience designing sovereign / on-premise AI deployments: NVIDIA NIM / NeMo, OpenShift AI, Run:ai, vLLM at scale, GPU capacity planning, and on-prem vector / graph stores.
- Background in security and governance: prompt injection defense, output filtering, data loss prevention, model risk management, NIST AI RMF, ISO/IEC 42001, and EU AI Act readiness; familiarity with the OWASP LLM Top 10, adversarial ML attack taxonomies (MITRE ATLAS), and red-teaming / evaluation techniques for LLMs; experience translating these frameworks into practical control designs rather than checkbox compliance.
- Experience fine-tuning, distilling, or post-training open-weight models (Llama, Mistral, Qwen, Gemma) for enterprise use cases.
- Industry experience in regulated verticals (financial services, healthcare, public sector, defense) where sovereignty and compliance are non-negotiable.
- Relevant certifications (AWS / Azure / GCP AI specialty, CKA/CKAD, CISSP, NVIDIA-certified) — useful, but capability is weighted more heavily than credentials.
