About the Role
We're looking for a Principal Engineer / Technical Lead to join a long-term project for a U.S.-based technology company building a secure digital payments platform for the healthcare and senior living industry.

The platform enables digital payment experiences for healthcare-related organizations and their users, supporting secure transactions, payment workflows, account visibility, and operational efficiency. Given the nature of the product, security, compliance, reliability, and architectural maturity are key aspects of the role.
You'll work closely with engineering teams and client stakeholders, helping validate technical decisions, identify risks, propose improvements, and guide the evolution of a production-grade platform built mainly with .NET / C# , Azure , and cloud-native architecture.

- Collaborate on security controls, code quality standards, deployment practices, and cloud governance.
- Identify technical debt and propose pragmatic, scalable remed
