Job description

Senior Software Engineer – IBM IMS TM/DB Modernization

We are seeking an accomplished Senior Software Engineer with deep expertise in IBM IMS™ Transaction Manager (TM) and Database (DB) application programming to drive the evolution of our IMS compatible technologies within our Enterprise modernization platform.

Responsibilities

• Architect & build IMS TM/DB-compatible technologies: design and develop key components that replicate or extend IMS TM and DB behaviors, including message handling, transaction scheduling, PSB/DBD structures, DL/I call compatibility, and hierarchical database semantics.
• Define and evolve architectural direction for the IMS replatforming runtime, ensuring parity with core IMS concepts while embracing modern opportunities.
• Translate IMS internals and application programming patterns into scalable, reliable components on distributed systems.
• Model real‑world IMS application scenarios (batch and online) within the modernization stack.
• Provide guidance on IMS constructs such as:
  • Message queues, scheduling, and transaction regions
  • DBD/PSB design and access paths
  • DL/I call flows, PCB handling, segment structure, and hierarchical locking
  • IMS batch processing interactions with TM and DB
• Partner with product and engineering leadership to ensure features meet enterprise‑grade reliability and performance expectations.
• Contribute to cross‑team engineering initiatives impacting compilers, runtimes, integration layers, and interoperability features.
• Mentor engineers across teams, facilitate deep technical reviews, troubleshoot complex runtime compatibility issues, and guide performance tuning strategies.
• Influence product roadmap decisions related to IMS replatforming, compatibility, and modernization.
• Engage with customers, field engineering, and support teams to understand real‑world IMS workloads and migration scenarios.

Qualifications

• 10+ years of professional software engineering, including senior‑level ownership of complex system‑level components.
• Direct hands‑on experience developing or maintaining IMS TM and DB applications on IBM z/OS (essential).
• Deep knowledge of IMS message‑driven architecture, PSB/PCB, DBD structures, DL/I calls, hierarchical database access, and transaction scheduling.
• Strong proficiency in C, C++, or similar systems languages.
• Experience delivering high‑availability, mission‑critical software systems.

Preferred Qualifications

• Experience with IMS exit routines, user exits, scheduling exits, or database utilities.
• Experience with mainframe modernization, replatforming, or emulation technologies.
• Familiarity with COBOL or PL/I application semantics and interactions with IMS environments.
• Exposure to modern distributed systems, cloud‑native design, or hybrid runtime architectures (Azure, AWS, Kubernetes).
• Experience building compilers, runtimes, interpreters, or compatibility layers for legacy workloads.

Who You Are

• Experienced engineer with strong domain knowledge of IMS application behavior and system fundamentals.
• Skilled at distilling mainframe concepts into modern software architecture.
• Motivated by the challenge of modernizing long‑standing, mission‑critical platforms.
• A mentor who raises the technical capabilities of the entire engineering organization.

Benefits & Compensation

• Annual salary range: $120,500.00 – $162,675.00 gross before taxes.
• Unlimited vacation time plus paid holidays and sick time.
• Health and wellness coverage options for employees and dependents.
• Life and disability coverage.
• 401(k) and Roth retirement savings with matching contributions.
• Monthly student debt benefit program.
• Tuition reimbursement and certificate reimbursement program.
• Leadership and skills training opportunities.
