Senior Principal Agentic Platforms Architect
About the Role
Mastercard powers economies and empowers people in 200+ countries and territories worldwide. Together with our customers, we’re helping build a sustainable economy where everyone can prosper. Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realise their greatest potential.
The AI Center of Excellence is seeking a Senior Principal Agentic Platforms Architect to lead the technical vision, architecture, and hands-on development of Mastercard's enterprise agentic AI platforms. This role demands deep, demonstrated expertise in building and shipping production-grade AI and agentic systems at enterprise scale within one of the most highly regulated environments in the world.
Reporting to senior leadership, this is not just a strategy-only role. You will:
- Own the E2E platform architecture for agentic AI systems
- Shape runtime orchestration, governance infrastructure, and production deployment
- Write code, review code, and set engineering excellence standards
- Build systems that operate at scale, under load, and under scrutiny—not just prototypes or proofs of concept
Role Responsibilities
-
Serve as the principal technical authority for agentic AI platform architecture, defining the design and evolution of:
- Runtime environments, governance layers, or orchestration engines
- Multi-tenancy infrastructure that supports enterprise-grade AI agents
-
Lead hands-on architecture and development of:
- Agent orchestration frameworks
- Tool and model integration layers
- Policy enforcement engines and guardrail systems
- Behavioral monitoring pipelines and evaluation infrastructure
-
Design and build scalable, resilient architectures for:
- Multi-agent coordination
- Agent-to-agent (A2A) communication protocols
- Memory governance
- Real-time observability across distributed deployments
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
