You will own integrations end to end: gathering requirements, building APIs and data flows, handling mappings and validations, testing, deploying under change-management controls and supporting what you ship. You will also build AI-driven automation into our delivery and support work. Structured training on IBM products is provided, but we expect you to arrive with solid integration and software fundamentals.

Key Responsibilities

• Design, develop and maintain integrations between IBM products, the web portal and client business systems

• Troubleshoot production issues across application, database and network layers; perform root-cause analysis and document fixes
• Write unit and integration tests; carry out deployments through dev, test and production following change-management and security standards
• Build AI-driven automation (LLM APIs, agents, scripted workflows) for monitoring, onboarding and support tasks
• Maintain technical documentation, runbooks and handover notes
• Participate in the support rotation for client environments during US business hours

Required Qualifications

• 2 to 4 years of hands-on software development or integration experience
• Solid understanding of how system integrations work: APIs, data flows, messaging, batch and file-based exchange
• Experience building and consuming REST APIs (authentication, error handling, versioning)
• Proficiency in at least one of Python, Java or JavaScript/Node.js
• Strong working knowledge of data formats (JSON, XML, CSV) and mapping/transformation between them
• Working knowledge of SQL and relational databases (Oracle, PostgreSQL, MySQL or similar)
• Comfortable on Linux: shell scripting, file permissions, log analysis, basic networking (ports, DNS, firewalls, TLS)
• Experience with Git and a basic understanding of CI/CD, testing and deployment practices
• Basic web application development experience (front-end or back-end)
• Interest in or hands-on experience with LLM APIs, AI agents or agentic workflows
• Understanding of data security fundamentals: encryption in transit and at rest, key and certificate handling, access control
• Strong troubleshooting and problem-solving skills; able to work through unfamiliar systems independently
• Clear written and spoken English; comfortable communicating directly with US-based clients
• Bachelor's or Master's degree in Computer Science, Software Engineering or a related field
