Job Description Senior Software Engineer C/Pro*C AIX-to-Linux Migration
Job Title: Senior Software Engineer C/Pro*C AIX-to-Linux Migration
Experience: 6 8 Years
Location: Chennai / Mumbai / Kolkata / Bangalore
Work Mode: As per project requirements
Role Overview
We are looking for a
Senior Software Engineer with 6 8 years of experience in
C, Pro*C, Unix/Linux, Python, and PVCS source control to support a large-scale
AIX-to-Linux migration program.
The candidate will be responsible for migrating legacy C and Pro*C applications from
AIX to Red Hat/Linux, resolving platform portability issues, developing Python-based migration/build automation, and implementing CI/CD pipelines using
GitHub Actions. The role also requires experience with Oracle database integration, automated testing, binary/application parity validation, deployment automation, and AI-assisted developer productivity.
Key Responsibilities AIX-to-Linux Migration
- Migrate C and Pro*C source code from AIX to Linux-compatible builds.
- Analyze and resolve portability issues involving:
- System headers
- Data types
- Compiler behavior
- POSIX/Unix APIs
- Library dependencies
- Linker dependencies
- Pro*C precompiler output
- Build and troubleshoot C/Pro*C applications on Red Hat Enterprise Linux (RHEL).
- Identify and resolve AIX/Linux behavioral and compilation differences.
- Analyze compiler warnings, build failures, runtime issues, and dependency conflicts.
- Ensure migrated applications maintain functional and business parity with the existing AIX implementation.
Python Build & Migration Automation
- Develop and maintain Python-based build and migration utilities.
- Create automation for:
- PVCS source extraction
- Source drift detection
- Makefile generation
- YAML manifest generation
- Deployment manifest creation
- Artifact management
- SHA-2/checksum-based selective deployment
- Automate repetitive migration, build, test, packaging, and deployment activities.
- Develop utilities to compare source/build artifacts across AIX and Linux environments.
CI/CD & DevOps
- Design, implement, and maintain GitHub Actions CI/CD pipelines.
- Build automated workflows for:
- Source checkout/extraction
- Compilation
- Unit testing
- Packaging
- Artifact publication
- Deployment
- Validation
- Manage CI/CD workflows across SourceBuildRepo and DeployStateRepo.
- Publish build artifacts to Nexus Repository or GitHub Packages.
- Implement automated build validation and deployment controls.
- Integrate quality checks and test execution into CI/CD pipelines.
AI-Assisted Engineering & Developer Productivity
- Build and deploy AI agents, GitHub Copilot skills, and accelerator tools to support the migration program.
- Develop AI-assisted solutions for:
- Portability analysis
- Code migration
- Cross-repository reasoning
- Impact analysis
- Test generation
- Documentation generation
- Developer productivity
- Apply an AI-first engineering approach to accelerate coding, testing, documentation, and migration analysis.
- Evaluate and integrate AI tooling into existing software engineering workflows.
C Unit Testing & Quality Engineering
- Evaluate and select an appropriate C unit testing framework, such as:
- Develop initial unit-test suites for shared C library functions.
- Build integration test harnesses for high-risk business processes.
- Integrate unit and integration testing into CI/CD pipelines.
- Improve test coverage and automated regression validation for migrated applications.
Parity & Validation
- Develop structured AIX-vs-Linux parity comparison tooling.
- Validate that Linux-built binaries produce equivalent business outcomes to AIX-built binaries.
- Compare:
- Application output
- Database state
- File outputs
- Transaction results
- End-to-end business processes
- Generate structured evidence and reports for migration sign-off.
- Investigate and resolve discrepancies between AIX and Linux execution.
Oracle / Pro*C Integration
- Work with Oracle Database and Pro*C applications during migration and testing.
- Validate embedded SQL and Pro*C precompiler behavior across platforms.
- Control and validate:
- NLS settings
- Database session state
- Query outputs
- Date/time and numeric formatting
- Transaction behavior
- Perform database-level parity verification between AIX and Linux application executions.
Deployment & Rollback
- Implement controlled deployment procedures for migrated applications.
- Develop backup-before-replace deployment logic.
- Implement rollback procedures for failed deployments.
- Create deployment runbooks and operational procedures.
- Support controlled AIX/Linux delivery and production migration activities.
- Ensure deployments are traceable, repeatable, and recoverable.
Documentation
- Create and maintain:
- Developer guides
- Build guides
- Migration guides
- Deployment guides
- Troubleshooting documents
- Technical design documentation
- CI/CD documentation
- Migration runbooks
