Title and Summary
Lead Software ArchitectOverview
Mastercard Dynamic Yield is looking for a Senior Software Architect to join our engineering organization and help shape the technical future of our platforms. This role is focused on owning end-to-end architecture for large-scale, cloud-native systems, while playing a hands-on leadership role in adopting and running agentic GenAI systems in production.
You will act as a technical focal point across teams, driving architectural coherence, accelerating technical feasibility for products, and ensuring our systems are scalable, secure, and future-ready. This is a senior, impact-driven role for an architect who leads through deep technical expertise rather than people management.
Role - Key Responsibilities
- Own and evolve end-to-end architecture for large-scale, cloud-native platforms and distributed systems
- Act as a technical focal point across multiple engineering teams, influencing technical direction and driving alignment without direct authority — building consensus through credibility and communication
- Partner with Product to proactively shape the long-term roadmap, bringing technical perspective into strategic planning
- Break down complex business and technical problems into clear system components, interfaces, and interactions
- Define and uphold architectural principles across scalability, resilience, security, and operability
- Architect and guide AWS-first platforms, including microservices, event-driven, and asynchronous systems
- Establish strong API design, versioning, and data contract practices across the platform
- Design, build, and run agentic GenAI systems in production, including orchestration, tool usage, planning, and state management
- Define production-grade practices for AI systems: observability, evaluation, reliability, safety, and cost control
- Drive architectural reviews, technical decision-making, and trade-off discussions
- Partner closely with Engineering, Product, and Data Science to accelerate technical feasibility and delivery
- Contribute to long-term technical strategy, platform evolution, and selective POCs where they create clear value
All About You
- 10+ years of professional software engineering experience, with time in architecture-focused roles
- Proven track record designing and operating large-scale distributed systems in production
- Strong, hands-on AWS experience (required)
- Deep knowledge of cloud-native and backend systems: microservices, APIs, events streaming, data flows
- Hands-on experience building and running agentic AI / GenAI systems in production (required)Including LLM-based agents, tool usage, planning, and stateful workflows
- Strong understanding of system design trade-offs, scalability, reliability, and operational concerns
- Ability to clearly explain complex technical concepts to both technical and non-technical audiences
Strongly Preferred
- Experience with RAG-based, multi-agent, or autonomous/semi-autonomous agent systems
- Experience integrating AI systems with existing platforms and APIs
- Background working closely with Data Science and ML teams
- Experience influencing architecture across multiple teams and products
- Familiarity with data platforms and pipelines (e.g., streaming, analytics, ML data flows)
What Makes This Role Impactful
- You will shape how platform and agentic AI systems are built responsibly and at scale
- You will act as a driver of technical feasibility and innovation, not a gatekeeper
- Your architectural decisions will directly impact system reliability, product velocity, and long-term business value
