Principal Enterprise Architect

Role Definition

Field Detail

Title Principal Enterprise Architect — AI Specialty (Platforms & Services / Hi-Tech)

Reports to Chief Architect / VP of Enterprise Architecture (or CTO office / Delivery leadership)

Level Principal / Distinguished Individual Contributor (most senior IC architecture band);

recognized technical authority

Function

Sets AI architecture strategy across a portfolio of Platforms & Services and Hi-Tech

accounts; the senior technical authority in front of clients and across delivery

teams

Accounts served

SaaS, fintech & payments, and enterprise-platform clients (e.g., Salesforce,

DocuSign, PayPal, Stripe, BlackLine, Intuit) and Hi-Tech / semiconductor (e.g.,

Applied Materials)

Scope Cross-account and cross-domain — customer, commercial, finance, and

operations platforms plus the data and AI/agentic layer that spans them

The Role in One Sentence

You are the senior AI architecture authority for a portfolio of Platforms & Services and Hi-Tech accounts —

defining how agentic and machine-learning capabilities are grounded in each client’s data, governed responsibly,

and standardized into reusable reference patterns, so that AI becomes a dependable layer of the client’s platform

rather than a collection of disconnected pilots.

Platforms & Services and Hi-Tech clients — SaaS, fintech and payments providers, and semiconductor and capital-

equipment leaders — run mission-critical, high-scale systems where reliability, security, and explainability are non-

negotiable. This role sits at that intersection: it brings deep enterprise-architecture discipline (TOGAF) together with

hands-on AI fluency (GenAI, agentic systems, MLOps) and enough domain range to be credible across a payments

platform, a finance-automation SaaS, and a semiconductor manufacturing workflow — and it is accountable for

making architecture and AI cohere at enterprise scale, in front of the client.

Key Responsibilities

Architecture Strategy & Vision

• Set the enterprise-wide AI architecture vision and target-state roadmap, and ensure every solution aligns to the

broader enterprise-architecture framework.

• Define target-state architecture roadmaps for each account that move clients toward AI-augmented operations,

intelligent automation, and better customer and employee experiences.

• Recommend architecture changes in response to technology and business trends; research emerging

technologies and advise leadership on their business impact.

• Act as the primary strategic liaison between executive business stakeholders and technical leadership —

conceptualizing, defining, and governing overarching system solutions.

AI & Agentic Systems Architecture

• Architect complex, multi-layered AI systems — scalable, resilient, secure, and explainable — tailored to each

client’s platform and mission-critical constraints.

• Design reference architectures for GenAI and autonomoagentic frameworks that automate intelligent

workflows across customer service, sales/commerce, finance and accounting, risk, and engineering/operations.

• Define how AI agents are grounded in enterprise context (customer data, product/catalog, financial and

transaction data, operational telemetry) and how they orchestrate actions safely across SaaS and internal

systems via APIs.

• Identify and prioritize AI/ML and GenAI use cases across the two verticals — e.g., fraud detection and risk

decisioning, payments and revenue/close automation, customer-support copilots, document intelligence; and

for Hi-Tech, yield and manufacturing analytics, EDA/design-flow assistance, and knowledge retrieval over

engineering data.

• Standardize the building blocks — LLM onboarding, RAG pipelines, vector stores, and agent/application patterns

— into reusable assets that accelerate delivery across accounts.

• Build quick, hands-on proofs of concept and working prototypes to validate feasibility, de-risk architecture

decisions, and win client confidence before committing teams to a full build. You prove concepts by building,

not just by slide.

Domain Architecture (Platforms & Services and Hi-Tech)

• Bring credible domain range across the account base: SaaS platforms and their extension/integration models;

fintech and payments (transaction processing, ledgers, identity/KYC, fraud and risk decisioning, dispute and

compliance flows); finance-and-accounting automation (close, reconciliation, controls); and Hi-Tech /

semiconductor workflows (design, verification, manufacturing and yield analytics, supply chain).

• Design secure, cloud-native, high-availability architectures — microservices, event-driven patterns (e.g., Kafka),

containerization (Kubernetes/Docker) across AWS, Azure, and/or Google Cloud Platform — that meet enterprise reliability and

low-latency requirements.

• Promote reuse, open APIs, and interoperability across each client’s platform landscape, integrating AI with

systems such as Salesforce, DocuSign, payment platforms, ERP/finance systems, and ServiceNow rather than

building in isolation.

Governance, Standards & Responsible AI

• Establish and run architecture governance — standards, principles, patterns, and reference architectures

ensuring consistency, scalability, security, and data integrity.

• Present and defend designs through the Architecture Review Board and Design Review Board; make sound

integration decisions grounded in open/industry standards.

• Embed AI governance, responsible-AI practices, data privacy, and domain-specific compliance into every AI

design — e.g., PCI-DSS, SOX/financial-controls, data protection and fraud/resilience requirements for fintech

and payments, and IP/data-sensitivity controls for Hi-Tech.

• Define the model-evaluation and benchmarking standards that AI systems must meet to be approved for

production — quality, safety, groundedness, drift, and cost — and make evaluation a required gate, not an

afterthought. Critically assess model and vendor performance claims rather than taking them at face value.

• Drive technology-portfolio rationalization and standardize architecture patterns across cross-functional teams.

Leadership & Enablement

• Provide technical leadership and mentorship to solution architects and engineering teams; foster a culture of

technical excellence and strategic thinking.

• Lead conversations with client executives (including C-level), business, and technical audiences — acting as a

trusted technical advisor, translating business strategy into architecture, and connecting technology to

measurable business value.

• Support pre-sales and solutioning — shaping proposals, estimates, and solution architectures, and running

discovery and design workshops that turn client pain points into scoped, winnable engagements.

• Partner across delivery teams, engineering, data, product, and client stakeholders to conceive, land, and evolve

reference architectures and platform roadmaps that carry across accounts.

Required Qualifications

Experience

• 12–15+ years in IT/enterprise architecture, with multiple years delivering architecture for large, complex

programs at enterprise scale.

• Proven track record architecting enterprise-grade AI solutions leveraging cloud-native architectures (AWS,

Azure, and/or Google Cloud Platform).

• Substantial experience serving Platforms & Services and/or Hi-Tech clients — SaaS, fintech/payments, or

semiconductor/capital-equipment — with enough domain depth in at least one to be immediately credible and

the range to ramp quickly on the others.

• Client-facing / consulting experience at a services firm or in an equivalent account-serving role, including pre-

sales, solutioning, and executive engagement.

• Hands-on enough to personally stand up a quick proof of concept or prototype — not solely a whiteboard

architect — and a track record of taking AI from PoC through to production at scale, not just pilots.

Technical Skills (Must-Have)

Area Depth

Enterprise Architecture Deep TOGAF (Architecture Development Method) practice; architecture review-

board governance; business value-stream mapping.

Domain Range

Functional depth in at least one of SaaS platforms, fintech/payments

(transactions, ledgers, identity, fraud/risk, compliance), finance automation, or Hi-

Tech/semiconductor workflows — and the ability to be credible across the

portfolio.

AI / GenAI Architectural experience with enterprise GenAI platforms/frameworks, ML model

deployment, RAG pipelines, and autonomoagentic AI frameworks.

Hands-On Prototyping

Retains enough hands-on ability (Python, notebooks, agent/LLM SDKs, cloud

services) to build quick PoCs and working prototypes independently — turning an

idea into something runnable in days, not a deck.

Cloud & Platform Integration

Cloud-native architecture across AWS/Azure/Google Cloud Platform — microservices, event-driven

(Kafka), Kubernetes/Docker — and integrating AI with SaaS and enterprise

platforms (Salesforce, DocuSign, payment platforms, ERP/finance, ServiceNow) via

open APIs.

AI Governance Responsible-AI practices, data privacy, model/AI governance, and domain-specific

compliance (e.g., PCI-DSS, SOX, data protection, fraud/resilience, IP sensitivity).

Model Evaluation

Fluent in how AI/LLM systems are evaluated — quality/accuracy, groundedness,

hallucination, safety, drift, and cost — enough to set benchmarking standards,

define acceptance gates, and judge model/vendor claims. Sets the bar and

governs it; does not need to hand-build every eval harness.

Integration & Cloud REST/Open APIs, microservices, event-driven and cloud-native architecture;

integration decisions grounded in open standards.

Technical Skills (Strong Plus)

• Real-time / low-latency decisioning and large-scale distributed systems (billions of transactions) for payments or

risk platforms.

• Data architecture — lakehouse strategies, information/data modeling, streaming (Kafka/Spark), governance and

consumption across domains.

• Hands-on with AI frameworks and tooling — LangChain/LlamaIndex, vector databases, MLflow,

PyTorch/TensorFlow, Hugging Face.

• For Hi-Tech: familiarity with semiconductor design/manufacturing, EDA/CAD workflows, or yield/manufacturing

analytics.

• Pre-sales and consulting delivery experience — proposals, estimates, and large-scale transformation programs.

Non-Technical Skills (Equally Critical)

Skill Why

Executive communication & client

trust

You simplify complex architecture for client executives, business, and technical

audiences alike, present through review boards, and earn trusted-advisor status

with the accounts you serve.

Pragmatism over purism Standards and frameworks are applied to deliver outcomes — not as bureaucracy.

You balance competing interests of cost, complexity, and business need.

Influence without authority As a principal IC you lead through architecture decisions and mentorship, not

headcount — landing standards across teams you don’t manage.

Vendor-neutral judgment You make interoperability and build-vs-buy calls on merit, promoting open

interfaces over lock-in.

Research mindset

You stay ahead of a fast-moving field, form and test hypotheses rather than follow

hype, and evaluate emerging models and techniques on evidence before betting

the architecture on them. Comfortable with ambiguity and with being proven

wrong by data.

Education

• Bachelor’s (or higher) in Computer Science / Engineering, Electrical Engineering, Applied Science, or

Mathematics — or equivalent practical experience.

• TOGAF certification strongly preferred; relevant cloud architecture certifications a plus.

What Success Looks Like

Horizon Outcome

Reusable assets Published, adopted AI reference architectures, RAG/agent patterns, and

accelerators reused across multiple accounts — not one-off builds.

Governance in place A functioning review process where AI designs are assessed for standards,

security, and responsible-AI/domain compliance before build.

Production AI at scale AI/agentic capabilities grounded in client data and running in production —

measurably reducing cost, risk, or cycle time, or improving experience.
