IBM Sterling OMS Developer

Senior IBM Sterling OMS Developer to join our Order Management engineering organization. This role is suited for an experienced engineer who enjoys working in complex enterprise ecosystems and who consistently demonstrates engineering excellence—strong design fundamentals, clean and maintainable code, disciplined unit testing, and a high bar for secure and compliant software delivery.

As a Senior Developer, you will play a key role in designing, developing, and enhancing solutions on the IBM Sterling Order Management System (OMS) platform. You will work on business-critical order management capabilities that support end-to-end commerce journeys, including order capture, sourcing, fulfillment orchestration, inventory visibility, payments, cancellations, returns/exchanges, and customer care workflows. Your work will directly contribute to building reliable and scalable OMS capabilities that meet demanding performance and operational expectations.

A major part of this role involves configuring and extending OMS core modules, implementing customized flows and integrations, and ensuring solutions are built with quality and operability in mind. You will also contribute to advanced customizations for Sterling Order Hub and Sterling Next Gen Call Center, helping deliver efficient experiences for business users and customer service teams.

This role requires strong collaboration skills. You will partner with cross-functional teams (product, architecture, QA, platform/operations, and other engineering squads) to translate business requirements into well-structured technical solutions. While you will not be expected to own infrastructure or production operations, you must be comfortable collaborating with those teams and designing software that aligns with enterprise standards for reliability, security, and maintainability.

We are looking for someone who is proactive, outcome-driven, and able to navigate ambiguity—an engineer who can dig deep into complex issues, propose pragmatic solutions, and raise the overall quality bar through strong technical contributions, code reviews, and mentorship.

What You’ll Do

• Design, develop, and implement solutions using IBM Sterling OMS to support enterprise order management needs.
• Configure and customize OMS core capabilities including (but not limited to):
  • Participant Modeling
  • Process Modeling (Sales, Returns & Exchanges, Purchase/DropShip, Transfer Orders)
  • Sourcing
  • Payment Processing
  • Inventory Management
  • Agents, event-driven automation, and background processes
  • SDF, Catalog, Pricing/Repricing, and tax-related recalculations (as applicable)
• Develop and enhance customizations for Sterling Order Hub and Sterling Next Gen Call Center, including workflows, screens, and user experience improvements aligned to business needs.
• Build and maintain integrations with internal and external services using REST APIs and JSON-based contracts; ensure robustness, backward compatibility, and clear versioning practices.
• Perform deep troubleshooting and root cause analysis across functional and technical issues; drive fixes that address underlying problems rather than symptoms.
• Optimize solution performance and stability through careful design, efficient query/integration patterns, and proactive technical improvements.
• Uphold and advocate for engineering best practices:
  • Clean architecture and readable, maintainable code
  • Strong unit testing and testable design
  • Peer reviews and shared coding standards
  • Secure coding practices and compliance with organizational quality/security checks (including security and dependency/license scanning expectations)
• Contribute to technical design discussions, document key decisions, and support knowledge sharing across the team.

What You’ll Bring

Required Experience & Skills

• 7–10 years of hands-on IBM Sterling OMS development/implementation experience in enterprise environments.
• Strong expertise in OMS functional and technical areas, particularly around orchestration workflows and core OMS modules.
• Strong hands-on development skills in Core Java (modern Java versions; advanced concepts preferred).
• Strong experience with RESTful services, JSON, and integration patterns.
• Solid working knowledge of SQL and data troubleshooting.
• Strong understanding of software engineering fundamentals: OOP, design principles, debugging, performance considerations, and code maintainability.
• Demonstrated commitment to code quality and unit testing (e.g., JUnit/Mockito or equivalent testing frameworks).
• Strong communication skills and the ability to work effectively with multiple stakeholders across teams.

Preferred / Nice-to-Have

• Experience with Spring Boot or similar frameworks for building supporting services.
• Experience with transformations such as XSL (where applicable in OMS customizations).
• Familiarity with containerized development concepts (e.g., Docker) and CI/CD fundamentals.
• Exposure to frontend technologies such as React and/or TypeScript (helpful but not the primary focus).
• Familiarity with modern engineering productivity tooling and/or AI-assisted development concepts is a plus.

What Success Looks Like in This Role

• You deliver OMS features and enhancements that are robust, scalable, and maintainable.
• Your code meets high quality standards with strong automated testing and clean implementation practices.
• You consistently troubleshoot and resolve complex issues with clear root cause analysis.
• You collaborate effectively across teams and contribute positively to engineering culture through reviews, documentation, and mentoring.
• You help raise the bar on engineering excellence, reliability, and long-term sustainability of OMS solutions.
