Principal Digital Architect

We are the Platform Architecture team responsible for defining and governing the architecture of large-scale, mission-critical digital platforms that underpin key business capabilities. As a Principal Digital Architect, you will own the end-to-end architecture solutions for complex systems-balancing scalability, performance, security, and rapid delivery-while influencing Enterprise technology strategy. This role requires strong technical depth, architectural judgment, and the ability to translate ambiguous business needs into durable, scalable solutions.

Core Responsibilities:

• Own and define solution and platform architectures for large-scale, distributed systems from concept through production.

• Create architecture that meets high standards for scalability, performance, resilience, and security.

• Partner closely with business leaders, product owners, engineering managers, and delivery teams to ensure architectural alignment with business outcomes.

• Assess, select, and introduce new technologies, including proof-of-concept development and architectural spikes.

• Establish and enforce architectural standards, patterns, and best practices across platform teams.

• Provide architectural guidance and mentorship to engineering teams, ensuring high-quality implementation.

• Ensure solutions meet security, compliance, and regulatory requirements.

• Produce and maintain clear architecture documentation, including rationale and trade-offs.

• Continuously evolve platform architecture to improve developer productivity, system reliability, and cost efficiency.
