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:

• cmocka

• Unity

• CUnit

• 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
