Heres what the opportunity supported through our TGS Talent Acquisition Team requires:

The Practice Architect II (AI/ML) is a senior hands‑on architect who owns technical direction and delivery execution for customer engagements building AI‑powered applications and digital platforms. The architect sets architecture direction and engineering standards, writes and reviews production code, and leads onshore and offshore engineering teams from design through production.

This is a delivery role, not pre‑sales. It is also not an individual contributor role the architect is accountable for the output of the teams they lead.

Key Accountabilities & Priorities Full Stack Agentic AI Architecture

Own architecture direction for agentic AI and full‑stack solutions across assigned engagements

Translate business and technical requirements into scalable, sustainable solution architectures





Set the architecture standards and design patterns delivery teams build against

Own code review and architecture review gates; make the final call on technical trade‑offs

Product Engineering & Innovation

Write production code for customer engagements approximately (4060)% of time

Build and own reusable accelerators, frameworks, and reference architectures that carry across engagements

Evaluate emerging technologies and architecture patterns, and decide what enters the stack

Unblock engineering teams on implementation problems

Delivery and Customer Relationship

Provide technical direction to engineering pods of engineers across concurrent engagements

Lead offshore technical leads; ensure design intent survives handoff to distributed teams

Mentor engineers on architecture, code quality, and modern engineering practice

Serve as the senior technical voice to customer architects, engineering leaders, and executives

Explain architecture decisions, risks, and trade‑offs to both technical and non‑technical audiences

Surface technical risks and dependencies early, with mitigation options

Drive alignment across customer product, engineering, and business stakeholders

Core Technical Skills

Agentic AI, AI‑powered solution design, and modern application architecture

Solution architecture and system design

Hands‑on software development and prototyping





AI‑assisted coding at scale for production deployment

Code reviews, engineering standards, and quality governance

Enterprise data onboarding: source access, ownership, entitlement, classification, and quality gating

Knowledge fabric: governed, queryable knowledge layer over enterprise data semantic modeling, entity resolution, lineage, freshness

RAG and retrieval architecture: vector and hybrid search, embedding pipelines, retrieval quality tuning, context and memory management

Agent security: agent identity, least‑privilege tool access, data‑boundary enforcement, audit

Agent execution harness: tool and component boundaries, orchestration, failure handling, human‑in‑the‑loop

Evaluation: offline and online harnesses, regression suites, groundedness and retrieval quality metrics, cost and latency instrumentation

Cloud‑agnostic delivery: portable across AWS, Azure, and GCP rather than tied to one provider's managed AI services

Stack: Python and TypeScript/Node, solid SQL, agent frameworks (LangGraph, LlamaIndex, or equivalent), MCP, containers, CI/CD, IaC

Minimum Qualifications

Bachelor's degree in Computer Science, Engineering, Information Technology, or a related discipline

(10)+ years in software engineering and architecture, including (3)+ years as a lead or principal architect

(2)+ years building production AI/agentic systems deployed and operating, not pilots or proofs of concept

Has onboarded enterprise data and built a governed knowledge or semantic layer, including entitlement and lineage

Can describe the security and identity model for agents acting on enterp
