System Integration Developer information

What is a system integration developer?

System Integration Developers are professionals who design, build, and maintain solutions that enable different software systems, applications, or databases to work together seamlessly. They are responsible for connecting disparate systems within an organization, often using APIs, middleware, or custom scripts. Their work ensures that data flows smoothly and processes are automated across platforms, improving efficiency and reducing manual work. System Integration Developers need strong programming skills, familiarity with integration tools, and a deep understanding of both the source and target systems involved.

What are some common challenges system integration developers face when working on large-scale integration projects?

System Integration Developers often encounter challenges such as ensuring compatibility between diverse systems, managing data consistency, and handling unexpected integration errors. Coordinating with multiple teams—such as software engineers, business analysts, and IT support—is critical to resolve issues quickly and maintain project timelines. Additionally, keeping up with evolving technologies and integration standards requires ongoing learning and adaptability. Addressing these challenges successfully can lead to smoother project execution and valuable experience for career growth.

What are the key skills and qualifications needed to thrive as a system integration developer, and why are they important?

To thrive as a System Integration Developer, you need strong programming skills, knowledge of integration patterns, and a background in computer science or related fields. Familiarity with integration platforms (like MuleSoft, Dell Boomi, or Apache Camel), APIs, and messaging systems, as well as certifications in relevant tools, is often required. Problem-solving abilities, attention to detail, and effective communication are crucial soft skills for collaborating across technical and business teams. These competencies ensure seamless system connectivity, data consistency, and efficient workflows in complex IT environments.

Job description

The ERP System Administrator is an individual contributor role within Alimentiv's Corporate Digital Enablement function, serving as the primary functional and technical owner of the Acumatica ERP platform that powers our Finance, Procurement, Logistics and Project accounting operations. This is a hands-on administration role - the successful candidate will configure, operate, and continuously improve Acumatica.

Another significant focus of the role is supporting the buildout of Acumatica's procurement functionality - supporting Corporate and Clinical operations as Alimentiv's procurement function matures. The role also owns the operational health of the SAP Concur-Acumatica integration via Celigo middleware and will play a central operational role in the planned annual Acumatica upgrades.
 
Positions available: 1, cross-posted in multiple countries. Please only apply to one posting. 
About the Role

Acumatica Administration & Finance Operations (~40%)

  Serve as the primary Acumatica administrator across the Alimentiv instance: configuration, user access, security, workflows, and module settings.

  Design and implement Finance solutions using native Acumatica functionality - Generic Inquiries, Business Events, push notifications, custom reports, and approval workflows.

  Support and optimize core Finance workflows: accounts payable, accounts receivable, general ledger, project accounting, billing, financial reporting, and month-end close.

  Partner with Finance to define requirements, document processes, and deliver Acumatica enhancements that improve data quality and operational efficiency.

  Troubleshoot and resolve Acumatica issues; coordinate with the Acumatica implementation partner while building internal capability over time and reducing vendor dependency.

  Maintain rigorous test environment discipline - validate all configurations in test before promoting to Production; ensure changes touching shared multi-tenant surfaces receive appropriate cross-domain approval.

Procurement & Projects Enablement (~25%)

  Partner with the Procurement function to continuously improve Acumatica's procurement functionality- vendor management, requisitions, purchase orders, Concur-Acumatica integrations.

  Configure and test procurement workflows aligned with Alimentiv's project-governed, goods & services-based procurement model.

  Maximize native Acumatica capabilities over customizations or third-party procurement platforms

  Support Procurement through discovery, requirements, configuration, testing, training, and operational rollout.

  Coordinate cross-domain approval and impact assessment for procurement-related changes given the shared instance and the downstream impact on Finance, Projects, and FP&A.

Integration Operational Ownership (~20%)

  Serve as the technical owner of the SAP Concur-Acumatica integration - understanding the end-to-end flow, triaging invoice processing, field mapping, and exception issues, and coordinating resolution with the integration developer and vendors.

  Monitor integration flows for errors, investigate root causes, and coordinate resolution with the integration developer and vendors - serving as the primary triage owner.

  Partner with the integration developer on the health of adjacent integrations including Host-to-Host banking, BambooHR HR sync, and ADF data pipelines to Power BI.

  Document integration architecture, field mappings, data flows, and change history to a standard that enables internal troubleshooting without vendor dependency.

  Lead integration change governance: ensure formal intake and approval before initiating vendor or system changes that could affect integrations.

Upgrade, Governance & Continuous Improvement (~15%)

  Play a central operational role in the planned Acumatica upgrades - customization risk assessment, validation, coordinated rollout, and post-upgrade stabilization.

  Operate within Alimentiv's gate-based Finance Change Delivery Process; use JIRA as the system of record for change approval and evidence.

  Maintain living documentation of Acumatica configuration, customizationsand governance decisions.
