Engineering Manager, Billing & Payments (Toronto)

At Constant Contact, we are seriously awesome people who take ownership and make an impact by operating with the mindset, integrity and courage of a small business owner. We empower people everywhere to pursue their dreams by providing the help and tools they need to grow online.

What You’ll Do:

Build & Scale the Platform

• Own end‑to‑end billing infrastructure and internal apps: payment gateways, subscription lifecycle, invoicing; backend in Java/Spring, front‑end in React, deployed on Kubernetes (OKD/EKS).
• Architect for growth with idempotency, retry semantics, loose coupling, and clean failure modes.
• Drive integrations with external platforms—including payment processors, tax engines, CRM systems and third‑party billing providers—owning the full contract from API design to production reliability.
• Actively manage technical debt, balancing new features, operational health, and debt reduction.
