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.

This is not a traditional senior developer role. We're looking for a highly experienced technical leader who can provide architectural guidance, strengthen engineering practices, support cloud migration decisions, and help consolidate a secure software development lifecycle in a regulated environment.

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.

• Support teams in building reliable, maintainable, and compliant software for a regulated payments environment.

• Participate in technical discussions with client-facing stakeholders, explaining decisions clearly and defending architectural recommendations.

• Mentor engineers and help raise the technical bar across the team.

• Contribute to long-term platform stability, security, performance, and maintainability.
