Careers at TCS: It means more
TCS is a purpose-led transformation company, built on belief. We do not just help businesses to transform through technology. We support them in making a meaningful difference to the people and communities they serve - our clients include some of the biggest brands in the UK and worldwide. For you, it means more to make an impact that matters, through challenging projects which demand ambitious innovation and thought leadership.
In an AI Architect role, it means stepping confidently into shaping the technical foundation of intelligent systems—combining deep architectural expertise with practical engineering leadership to design AI solutions that are scalable, secure, and future-ready. It’s about transforming complex AI and data capabilities into robust, enterprise-grade architectures, guiding cross-functional teams, and ensuring every design decision enables meaningful, measurable impact across the organization.
The Role
In this role, you will define the architectural blueprint and technology foundations for AI-driven solutions that transform how customers in dynamic, data-intensive industries operate, scale, and innovate. You will design robust, future-ready AI architectures that enable automation, advanced analytics, and intelligent decision-making across complex digital transformation programmes. With access to cutting-edge AI frameworks, high-performance computing environments, and modern data platforms, you will guide engineering and data science teams in building secure, scalable, and ethical AI systems. This role empowers you to shape end-to-end AI ecosystems—accelerating delivery, enhancing customer experience, strengthening operational resilience, and driving their journey toward a more intelligent, AI-enabled future.
Your Responsibilities:
- Define the enterprise AI architecture vision and reference patterns; align them to business goals, risk posture, and engineering standards across cloud and hybrid environments.
- Design secure, scalable AI solutions covering data ingestion, feature engineering, model training, inference, and continuous feedback loops.
- Establish integration patterns (APIs, events, microservices) to embed model-powered capabilities into existing platforms with clear service boundaries.
- Define enterprise-wide AI architecture guidelines, reusable components, and long-term roadmap to ensure consistency and acceleration of AI initiatives.
- Implement MLOps/LLMOps pipelines for versioning, CI/CD, approvals, and controlled promotion across environments; enforce reproducibility.
- Work closely with product owners, data scientists, engineers, security teams, and business stakeholders to ensure architecture translates into high-value solutions.
- Enforce IAM least-privilege with IAM Conditions, organization policies, and scoped service accounts; integrate BeyondCorp for zero-trust access.
- Operationalize observability using Cloud Logging, Cloud Monitoring, Error Reporting, Trace, and Profiler; build model/LLM telemetry dashboards and alerts.
- Identify the right AI/ML frameworks, cloud services, model orchestration tools, and infrastructure components that align with business needs and scalability goals.
- Architect APIs, microservices, and integration patterns that embed AI capabilities seamlessly into existing workflows and digital products.
