Fluent OMS Developer

Build and extend user interfaces with the OMX UX Framework, including custom form fields and configured web apps that react to workflow state.

Integrate Fluent Commerce with surrounding systems — ecommerce platforms (e.g. commercetools, SAP, Salesforce, Adobe), ERPs, WMS, POS, payment, and carrier/3PL services — using event-driven patterns, webhooks, connectors, and middleware.

Configure inventory and sourcing logic, including Available-to-Promise (ATP), fulfilment location networks, and sourcing strategies.

Write automated tests for rules and workflows (e.g. JUnit with Fluent's util-test / WorkflowExecutor utilities), and validate behaviour with Postman and the GraphQL explorer.

Package and deploy solutions as modules/plugins across environments; support CI/CD, monitoring, and release processes.

Troubleshoot production issues — diagnosing stuck orders and waves by inspecting audit events and workflow paths, and re-triggering or remediating safely.

Contribute to technical design, code reviews, documentation, and estimation; [mentor junior developers and share Fluent best practices across the team].

Must-have skills and experience

6+ years of professional software development, with strong core Java skills.

Hands-on experience building on Fluent Commerce / Fluent Order Management — workflows, rules, and the Fluent SDK. (For candidates new to Fluent: strong Java plus another OMS/orchestration platform, with willingness to certify quickly.)

Solid GraphQL experience (schemas, queries, mutations) and comfort with REST, JSON, and API design.

Understanding of event-driven and asynchronous architectures — webhooks, message/event handling, and integration between distributed services.

Experience integrating enterprise systems (commerce front-ends, ERP, WMS, POS, carriers) through APIs and middleware.

Familiarity with cloud (AWS preferred), Git-based version control, and CI/CD pipelines.

Strong debugging and problem-solving skills, and the ability to reason about data flowing through a complex orchestration engine.

Clear written and verbal communication in English, and the ability to work with both technical and business stakeholders.

Nice to have

Fluent Commerce certification (via the Fluent Commerce Builders Portal / Learning Pathways) or a clear plan to obtain it.

Front-end skills (JavaScript / TypeScript / React) for deeper OMX UX Framework work.

Experience with composable / MACH commerce and platforms such as commercetools, or with the broader headless ecosystem.

Domain knowledge of retail order management and omnichannel fulfilment — Click & Collect / BOPIS, Ship-from-Store, split fulfilment, returns and exchanges.

Experience migrating from or integrating with other OMS platforms (e.g. IBM Sterling, Manhattan, Salesforce OMS).

Exposure to serverless (AWS Lambda), containers, and infrastructure-as-code.
