Senior C engineer for large-scale payments platform migration from AIX to Linux/AWS.
Lead a hands-on migration of a legacy payments system from UNIX/AIX to cloud-native Linux and AWS, refactoring C applications with deep systems knowledge. You'll drive analysis, consolidation, and technical decisions with full ownership, then transition into long-term maintenance and client work. Requires 5+ years of C expertise, proven AIX-to-Linux porting skills, and fluency in UNIX toolchains; domain knowledge of payments and cloud platforms is a bonus.
