Design, update, and maintain integrations across Salesforce, MuleSoft, ERP, and third-party systems
Implement and optimize data synchronization flows, including retries, transformations, validation, and error handling
Work with Salesforce platform components, including Apex, APIs, metadata, and business logic
Contribute to improving the platform’s stability, maintainability, and observability
Collaborate with developers, QA engineers, and stakeholders to implement improvements based on audit findings
Participate in deployment, release, testing, and environment promotion processes

Troubleshoot production issues and perform root-cause analysis
Requirements:
5+ years of experience in backend development, integration engineering, or solution-oriented platform development
Strong hands-on experience with Salesforce-based systems and integrations
Experience working with MuleSoft, including flows, connectors, transformations, and integration logic
Good understanding of ERP integrations, ideally with Sage or similar systems
Strong backend development skills in Java and/or JavaScript / Node.js
Practical experience with SQL, relational databases, ETL/data mapping, and system-to-system data flows
Experience troubleshooting and improving live production systems
Ability to work with existing codebases, understand legacy decisions, and gradually improve architecture and maintainability
Familiarity with Git, CI/CD pipelines, deployment processes, and testing practices
Good communication skills and the ability to collaborate with technical and non-technical stakeholders

Nice to have:
Experience with Salesforce Commerce

Previous experience modernizing or restructuring underdocumented systems
What we offer:
Work on a business-critical platform that directly supports real operational workflows
Join a project where your contribution will have visible impact on product quality and platform stability
Take ownership of meaningful technical improvements rather than just routine maintenance
Be part of a team that values engineering quality, collaboration, and practical problem-solving
Contribute to the next stage of development for a platform with clear business importance
