Job description

Why Valtech? We’re the experience innovation company - a trusted partner to the world’s most recognized brands. To our people we offer growth opportunities, a values -driven culture, international careers and the chance to shape the future of experience.

The opportunity

At Valtech, you’ll find an environment designed for continuous learning, meaningful impact, and professional growth. Whether you're pioneering new digital solutions, challenging conventional thinking or building the next generation of customer experiences, your work will help transform industries.

As a Fluent Commerce Developer, you are passionate about experience innovation and eager to push the boundaries of what’s possible. You bring 6+ YEARSof 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 GraphQLAPI — 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 theGraphQLexplorer.

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.
• 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.
• Experience with composable / MACH commerce and platforms such ascommercetools, 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.
