Job Description - System Integration Engineer (Mulesoft)

An Integration Engineer with hands-on experience in API integration projects. The ideal candidate will bridge the gap between business stakeholders and technical teams, driving seamless API-based connectivity across systems and ensuring integration solutions align with enterprise architecture and business objectives.

Make an impact by:

Business Requirements & Analysis

  • Collaborate with business users, product owners, and architects to gather, document, and refine integration requirements.
  • Translate business processes and functional requirements into API specifications, data mappings, and integration use cases.
  • Conduct analysis between existing systems and desired integration outcomes.


API Integration & Design Support

  • Work closely with MuleSoft developers and architects to define API interfaces, message structures, and validation rules.
  • Create detailed specifications including RAML or TMForum definitions, payload examples, and data transformation logic.
  • Participate in API design reviews and ensure adherence to enterprise integration standards and governance frameworks.

Project Delivery & Documentation

  • Support end-to-end integration delivery across planning, testing, and deployment phases.
  • Prepare project documentation such as user stories, process flows, sequence diagrams, and integration test cases.
  • Validate implemented APIs against business requirements and assist in Sanity Test and user acceptance testing (UAT).

Stakeholder Management

  • Act as the liaison between business users, ServiceNow development teams, and vendors (e.g., Mulesoft, ServiceNow, in-house core systems).
  • Communicate project status, risks, and issues effectively to both technical and non-technical stakeholders.

Governance & Continuous Improvement

  • Assist in maintaining API documentation portals and reuse catalogues.
  • Identify opportunities to streamline integration processes and promote reuse across applications.
  • Contribute to establishing best practices for API lifecycle management, security, and versioning.

Skills for Success:

  • Degree in Computer Science / Engineering or related discipline
  • Hands-on experience with MuleSoft Anypoint Platform, including API management and integration lifecycle.
  • 3–5 years of experience in large-scale IT integration projects.
  • Hands-on experience working in Agile Scrum teams delivering integration or platform features in iterative sprints.
  • Proficiency in writing user stories, acceptance criteria, and maintaining a well-groomed product backlog using tools like Jira or Azure Boards.
  • Proficiency in designing Mule components (Mule ESB, Anypoint Studio, ETLs, flows, MEL, message modelling, Routing, Filtering, Database, Exception Handling, API Management)
  • Understanding of MCP (Model Context Protocol) architecture: resources, tools, prompts/skills, and how they provide context to AI models.
  • Knowledge of how to integrate MCP with enterprise systems (e.g., via HTTP, webhooks, or event buses) for orchestration
