Job Overview
The Manager, Product & Engineering - Digital Common API Platform (DCAP) leads the strategy, delivery, and evolution of a shared, enterprise-grade API platform that enables digital products, channels, and partner integrations at scale.

This role blends product leadership, engineering execution, and people management to ensure APIs are secure, scalable, reusable, and aligned to business outcomes. Operating in an Agile/DevOps environment, this leader manages cross-functional teams of product managers, software engineers, and platform specialists (typically 5-10 FTEs plus onshore/offshore partners).

As adoption of the platform continues to grow, this role is critical to ensuring DCAP remains reliable, secure, and easy to consume - while scaling to support higher traffic volumes, broader enterprise usage, and new integration patterns.

Why This Role Matters

The Digital Common API Platform is a foundational capability that enables teams across the organization to build, integrate, and deliver digital experiences faster and more consistently.

As more products and partners rely on shared APIs, the platform must balance speed with stability, flexibility with governance, and near-term delivery with long-term scalability. This role plays a central part in establishing DCAP as a trusted, reusable platform that reduces duplication, improves developer experience, and accelerates time-to-market across digital initiatives.

The Manager, Product & Engineering is accountable for:

• End-to-end product and engineering ownership of the Digital Common API Platform
• Delivery of reliable, secure, and well-governed APIs consumed by multiple teams
• Building and leading high-performing product and engineering teams
• Driving platform adoption, standardization, and continuous improvement
• Partnering closely with application teams, architecture, security, and vendors to align platform capabilities to enterprise needs

In the near term, this role will focus on stabilizing and optimizing the platform as adoption grows, improving delivery predictability, governance, and developer experience. Over time, the role will evolve toward scaling the platform, expanding reusable APIs, and advancing observability, resiliency, and automation.
