    • Assembler / HLASM
  •  
    • C and C++ (especially in mainframe or systems-level integrations)
  •  
  • Deep understanding of z/OS architecture and environments
  • Experience with IBM utilities (DFSORT, IDCAMS, IEBCOPY, etc.)
  • Strong debugging, performance tuning, and system-level troubleshooting skills
  • Proven leadership experience in a mainframe development environment
Nice-to-Have Skills
  • Experience with DB2, IMS, or other mainframe databases
  • Familiarity with API enablement or mainframe modernization tools
  • Exposure to hybrid architectures (mainframe + cloud/distributed systems)
  • Understanding of DevOps practices in legacy environments
What We Offer
  • Competitive salary based on experience
  • Flexible remote work environment
  • High-impact role influencing critical systems
  • Opportunity to modernize and innovate within a stable infrastructure
  • Collaborative and efficient team environment
Why Join Anchor Software?
