Principal Engineer & Technical Lead — Azure / Containers

About Aperia Solutions Aperia Solutions is a leading payments SaaS company headquartered in Dallas, Texas. We build risk management, residuals accounting, compliance, and analytics platforms used by merchant banks, ISOs, payment processors, and other participants in the credit card payments ecosystem. Operating under PCI DSS 4.0 compliance across dual on-premises datacenters (Allen, TX and Chicago, IL) plus Azure cloud, we process high-volume payment data for some of the industry’s largest players.

We’re in the middle of a significant platform modernization program: a next-generation risk analysis and scoring platform on Microsoft Fabric, an AI-powered ingestion platform, new AI-native applications, and ongoing evolution of the products our clients rely on every day. The teams executing this work are deliberately small and senior, with executive-level support and minimal bureaucracy. Every senior hire is a founding contributor to the architecture and the code.

Role summary We are hiring a Principal Engineer and Technical Lead: a builder first, with deep architecture and enterprise design pattern experience behind every line of code. This person is the SVP of Technology's chief lieutenant on technical execution. You will take on the heaviest technical lifting, prove risky ideas with working prototypes, turn approved architecture into production systems, and hold distributed engineering teams to a high technical bar.

This is a hands-on role, not an architecture-only or slidewar
