AI Solutions Architect

Distinguished Tech Innovator

3Pillar warmly extends an invitation for you to join an elite team of visionaries. Beyond software development, we are dedicated to engineering solutions that challenge conventional norms. Envision you: steering projects that redefine urban living, establish new media channels for enterprise companies, or drive innovation in healthcare.

Your invaluable expertise will serve as the cornerstone in shaping the future direction of our endeavors.

This role is the primary technical authority within a client engagement, hands-on across the AI-driven delivery lifecycle (AI-DLC). The Architect owns high-level design choices, dictates technical standards, and stays directly engaged in the codebase — designing and building the architecture that embeds AI agents across the SDLC, from requirements and code generation through testing, documentation, and release. The idóneo candidate is as comfortable pairing with an AI agent on a pull request as they are presenting an architecture roadmap to a client executive.

Key Responsibilities

AI-Driven,



Agentic Delivery

• Design and build the architecture that embeds AI agents across the SDLC — requirements gathering, code generation, testing, documentation, and release management.
• Set technical standards for where AI-assisted approaches are trustworthy versus where human-in-the-loop oversight is required to protect quality, compliance, and client trust.
• Stay hands-on in the codebase — reviewing, building, and validating AI-driven approaches against real engineering constraints — and feed findings back into 3Pillar's delivery practices.
• Assess and plan the insertion of new AI/agentic tooling into existing technology stacks and client environments.

Solution Development & Pre-Sales

• Partner with the Solutioning team on pre-SOW technical solutioning — shaping architecture, approach, and feasibility ahead of contract execution.
• Translate client requirements into a credible tech
