Solution Architect - AI Applications and Agents (Azure)3Pillar is an AI transformation partner on a mission to help enterprises build the AI-native products and intelligent agents that will define the next era of business. With teams across North America, Europe, Latin America, and Asia, we work with the most ambitious companies in financial services, healthcare, media, and technology - helping them move faster, modernize boldly, and compete on their own terms. Our HelixAI platform and Helix Pods delivery model put our engineers at the center of real agentic transformation - doing work that is open, portable, and built to last. We are building the future of enterprise AI.
About The RoleYou architect products that put large language models and agents into production for clients: deciding where AI belongs and where it does not, designing the agent, retrieval and evaluation layers, and building the application architecture around them on Azure. You own the architecture from the first design decision through production and lead the engineers who build it.



You will work across engagements and domains.
Applied AI experience is the deciding requirement for this role. Azure platform or infrastructure architecture experience alone does not qualify.
What You Will Do
- Set the AI boundary on every product: what runs deterministically, what the model handles, and how human review and evaluation gate each release.
- Design agent and retrieval layers: Azure OpenAI behind a swappable model port, Semantic Kernel or Microsoft.Extensions.AI (or the Node equivalents) for orchestration and tool calling, Azure AI Search for retrieval-augmented generation, Azure AI Document Intelligence for document ingestion.
- Define how AI features are measured: evaluation sets, error thresholds, regression runs in CI, cost and latency telemetry, and the human-review workflow that catches what evaluations miss.
- Design the application architecture around the AI: hexagonal systems with a generic domai
