Key Responsibilities

Deal intake and GTM interlock

• Act as the primary technical and delivery interlock for assigned AI opportunities from qualified intake through solution approval, contracting and handover to delivery.
• Engage with regional GTM, sales and solution teams early in the opportunity lifecycle to understand the client’s business problem, intended outcomes, technical environment, data landscape and commercial requirements.
• Assess whether the opportunity is sufficiently qualified for Global AI Delivery engagement and identify any additional information, discovery or customer validation required.
• Review use-case descriptions and business requirements to assess whether the proposed use of AI is appropriate, feasible and aligned with measurable client outcomes.
• Support structured discovery sessions with clients and internal stakeholders, translating business requirements into actionable technical and delivery requirements.
• Identify the specialist capabilities required to support the pursuit and coordinate targeted engagement from Global AI Delivery Unit, security, legal, commercial and regional delivery teams.
• Manage the involvement of delivery specialists carefully, ensuring that delivery expertise is used for material design decisions and specialist validation without drawing delivery teams unnecessarily into general pre-sales activity.
• Maintain clear communication with opportunity owners regarding solution status, outstanding decisions, risks, dependencies and readiness for assurance.

AI solution architecture and design

• Shape or own the end-to-end architecture of AI solutions across application, model, data, integration, infrastructure and security domains.
• Evaluate architecture options and select appropriate AI models, cloud services, orchestration frameworks and third-party technologies, balancing cost, performance, scalability, security and delivery complexity.
• Define secure integration, functional and non-functional requirements, data governance and responsible AI requirements for the proposed solution.
• Align solutions with NTT DATA reference architectures, reusable assets, delivery patterns and approved technology standards.

Commercial solution development

• Work with commercial, finance, sales and delivery stakeholders to develop a commercial construct aligned to the architecture and delivery model.
• Validate estimates, rate-card assumptions, third-party costs, consumption charges and contingency, ensuring all material delivery costs are represented.
• Ensure the resource model, delivery estimate, pricing, contribution and margin assumptions remain internally consistent, with uncertainty managed through appropriate commercial mechanisms.
• Support pricing and approval processes and challenge commercial constructs that create unmanageable technical or delivery risk for NTT DATA.

Scope and statement-of-work development

• Support the drafting and review of proposals and statements of work, defining scope, deliverables, milestones, assumptions, exclusions, dependencies, client responsibilities and acceptance criteria.
• Ensure contractual artefacts accurately reflect the approved architecture, delivery approach, resource plan and commercial model, without ambiguous or unbounded commitments.
• Coordinate legal, security, data protection and responsible AI input and support negotiation of technical and delivery-related contractual terms.

Deal assurance and governance

• Assess the completeness and quality of the proposed solution across architecture, technical feasibility, delivery readiness, resource requirements, commercial consistency and risk treatment.
• Identify material technical, data, security, privacy, legal, commercial and delivery risks and ensure appropriate owners and mitigations are in place.
• Prepare and present assigned opportunities for relevant assurance and approval gates, coordinating required stakeholder review and sign-off.
• Provide a clear, evidence-based assurance recommendation: proceed, proceed subject to conditions, return for rework or do not proceed in the proposed form.
• Track assurance conditions, escalate material concerns and maintain appropriate decision records; ensure independent review where the architect has materially developed the solution.

Delivery planning and resource model

• Translate the solution into a realistic delivery approach covering workstreams, deliverables, milestones, dependencies and mobilisation.
• Define or validate the resource model, effort estimates, skills, location strategy and use of global delivery centres, partners or subcontractors.
• Assess delivery timelines and define appropriate governance, roles, responsibilities, escalation and change control.
• Identify requirements for managed services, production support, model monitoring, platform operations or continuous optimisation where applicable.

Prototyping and feasibility validation

• Develop, lead or coordinate prototypes and proofs of concept where required to validate feasibility, reduce delivery risk or demonstrate the proposed solution.
• Test material assumptions relating to model performance, data, integration, security, scalability, latency and consumption cost, with clear success and exit criteria.
• Translate prototype findings into the production architecture, estimate, assumptions and risk position, engaging specialist engineering support where required

Transition and handover to delivery

• Maintain a controlled solution baseline through contracting and mobilisation, ensuring material changes are reflected consistently across deal artefacts.
• Lead the transition to delivery, providing the approved architecture, scope, commercial baseline, resource plan, assumptions, dependencies, risks and client commitments.
• Support early mobilisation, resolve gaps between what was sold and what is being delivered, and capture feedback to improve future solutioning and estimates.

Reuse and capability development

• Contribute reusable AI architectures, delivery patterns, prototypes, estimation models, proposal assets and commercial assumptions informed by pursuit and delivery experience.
• Share knowledge, coach regional teams and continuously improve the methods, templates and governance controls used by the AI Deal Intake, Assurance & Governance function.

Knowledge and Attributes

• Advanced enterprise solution architecture knowledge across application, integration, data, infrastructure, cloud and security domains.
• Strong understanding of AI, generative AI and agentic AI solution patterns, including model selection and evaluation, RAG, prompting, grounding, data pipelines, APIs and vector databases.
• Strong knowledge of major cloud platforms and their AI, data, integration and security capabilities, with working knowledge of software engineering, DevOps, MLOps and LLMOps.
• Ability to develop or lead prototypes and assess the path from proof of concept to a secure, scalable and supportable production solution.
• Strong understanding of security, privacy, compliance, data governance and responsible AI considerations.
• Commercial acumen across estimates, rate cards, pricing models, third-party costs, contribution, margin, contingency and cost recovery.
• Understanding of statements of work, contractual assumptions, acceptance criteria, client dependencies, change control and delivery transition.
• Strong client-facing consulting, communication and stakeholder-management skills across technical, commercial, delivery and executive audiences.
• Ability to exercise constructive challenge, make evidence-based decisions and manage multiple complex opportunities under demanding pursuit timelines.
• Strong analytical capability and attention to detail when reviewing solution, commercial and contractual artefacts.
