Will you shape the future or will the future shape you? 

The opportunity

As a member of the Americas Tax Technology Group (ATTG), you will join a technology organization dedicated to developing and maintaining innovative solutions that support our client-facing Tax professionals. ATTG collaborates closely with Tax to create digital and mobile tools designed to enhance internal operations, as well as advanced capabilities in data-driven management, workflow optimization, analytics, automation, and artificial intelligence to address current challenges and shape future opportunities.

The Solutions Architect role is part of the Architecture and Standards pillar, which designs market-leading solutions and sets standards for ATTG. This role focuses on designing architecture that is secure, compliant, easy to monitor, and ready for production, with an emphasis on AI-powered and AI-integrated capabilities—including agentic and multi-agent systems.

Your key responsibilities

• Ensures the architecture of solutions is aligned with the direction of the organization in terms of technology and business strategy, with clear AI value realization goals.
• Drives effective decision making to steer, harmonize and accelerate efforts within the portfolio, documents trade-offs across performance, cost, risk, and delivery timelines.
• Accountable for the solution architecture of products within the portfolio, including agentic AI and generative AI capabilities.
• Ensures the direction and implementation of a solution is true to its design; manages change appropriately through governance.
• Makes informed Build vs. Buy decisions by consistently following established evaluation processes, including model/platform assessments and vendor due diligence.
• Routes technology purchase requests through appropriate channels to ensure alignment with Global Procurement purchasing requirements.
• Ensures solution designs specify technologies & tools approved for use by Tax Quality, Risk Management & Independence, including AI safety controls.
• Collaborate with Solution Delivery Leadership (SDL) and Business Technology Leadership (BTL) to devise AI solution delivery strategy and operating model.
• Assists with mapping business technology strategy to solution strategy, including AI capability roadmaps and reusable building blocks.
• Participates in rationalization of the latest market trends, ATTG and EY Fabric capabilities, and emerging AI standards.
• Facilitates preparation of technical solution options and advises on technical and business value, including cost/performance and risk posture.
• Develops standards and reference architectures to accelerate delivery through repeatable actions, reusable components, and shared services.
• Identifies programs to deliver architectural leverage and scale through reusable components
• Works alongside governance bodies in ATTG to form part of the organization’s overall governance picture, embedding compliance through automation and policy enforcement.
• Designs products and services for minimal human intervention in deployment and operation, including CI/CD, version pinning, and rollback strategies for agents and models.
• Ensures governance is met through automation and policy enforcement to reduce manual process gates, including traceability and guardrail logging.
• Ensures compliance with standards for solution architecture and integration of relevant building blocks already available.
• Defines robust architectures for building new applications and releases, leveraging and enhancing existing building blocks, or creating new reusable components.
• Architects agentic AI capabilities: single/multi-agent patterns, tool orchestration, planning/execution loops, episodic and long-term memory, retrieval grounding, and policy/guardrails.
• Designs multi-agent workflows: task decomposition and coordination (broadcast, hub-and-spoke, supervisor/worker), conflict resolution, shared memory, and evaluation harnesses.
• Leads enterprise-grade integration patterns: function calling/skills catalogs, event-driven flows, APIs/services, RAG pipelines, vector stores, streaming, and observability.
• Applies and promotes standards and protocols such as OpenAPI 3.1, Model Context Protocol (MCP), and agent-to-agent (A2A) patterns where applicable.
• Leverages Microsoft Azure AI Foundry capabilities (model selection, Agent Service, Agent Framework/SDK, Hosted Agents, and observability/evaluations) to deliver scalable solutions.

Skills and attributes for success

• Ensures production operations and reliability: Kubernetes or serverless hosting, reliability engineering, cost/performance tuning, and incident response readiness.
• Ensures security and compliance by design: OAuth2/OIDC, secrets management, data boundaries, content filtering, and PII handling/redaction.
• Partners with others inside and outside the organization to gather requirements and formulate appropriate architecture; advocates and compromises to reach mutually acceptable solutions.
• Works closely with Studio and engineering teams to translate architecture into delivered value and measurable outcomes.

To qualify for the role, you must have

• A bachelor’s degree (computer science, engineering, accounting, finance preferred) or equivalent work experience, master’s degree preferred.
• 10+ years of experience in solution/enterprise architecture and building enterprise software products; management experience a plus.
• Ability to clearly articulate both problems and proposed solutions to technical and non-technical stakeholders.
• Proactive approach to identifying issues and presenting solutions/options, leading where appropriate to resolution.
• Understanding of long-term business objectives and ability to suggest technical strategies to meet objectives through innovation, including AI-enabled capabilities.
• Strong experience with architectural styles and patterns (cloud-native, microservices, event-driven, API-first).
• Experience architecting agentic AI and/or generative AI solutions, including multi-agent workflows, tool orchestration, memory, and RAG grounding.
• Experience with integration patterns for AI systems (function calling/skills catalogs, vector stores, streaming, observability).
• Experience with Microsoft Azure AI Foundry: model selection/cost trimming; Agent Service; Agent Framework/SDK; Hosted Agents; and observability (tracing, metrics, evaluations, Application Insights/OpenTelemetry).
• Excellent knowledge of software development methodologies and processes (Agile/DevOps) and strong CI/CD discipline.
• Track record that includes the design and release of high-quality, high-performance, enterprise-level software products/applications.
• Excellent decision-making skills with the ability to balance conflicting interests in a complex and fast-paced environment.
• Strong analytical, prioritization, and troubleshooting skills; strong documentation skills for C-level consumption.
• Experience designing and implementing hybrid cloud solutions.
• Strong security and compliance fundamentals: OAuth2/OIDC, secrets management, data boundaries, content filters, and PII handling.
• Comfortable communicating architecture to all levels of management and customers; responsive and decisive in adjusting architecture per requirements and technology evolution.
• Working experience in Business Architecture is beneficial.

Ideally, you’ll have

• Ability to understand and learn tax law and technology implications.
