The role

As aFluent Commerce Developer  you are passionate about experience innovation and eager to push the boundaries of what's possible. You bring 3+ YEARS of experience, a growth mindset and a drive to make a lasting impact.

You will thrive in this role if you are:

• A curious problem solver who challenges the status quo
• A collaborator who values teamwork and knowledge-sharing
• Excited by the intersection of technology, creativity and data
• Experienced in Agile methodologies and consulting (a plus)

Role responsibilities

• Design and implement order orchestration Workflows on the Fluent Commerce platform — modelling states, rulesets, triggers, and user actions that encode each client's business processes.

• Develop custom Rules in Java using the Fluent SDK (Rules SDK) to implement business logic such as validation, sourcing, allocation, fulfilment, and notifications.

• Build and consume the platform's GraphQL API — writing queries and mutations against Fluent's data entities (Order, Fulfilment, Inventory, Availability, Returns, Location) and designing efficient data access for downstream consumers.

• 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 qualifications

• [3+] 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 qualifications

• 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

• Experience: 3+ years
• Seniority: Mid Level
• Languages: English
