Role Description

ServiceTitan is looking for a Senior Integration Developer to design, build, and maintain enterprise-class integrations and automation workflows. This role is a key member of the Integration/Automation team and will focus primarily on the Workato platform, with exposure to MuleSoft and other middleware technologies.

You will support cross-functional teams by serving as a technical resource for integrations spanning ServiceTitan, Workday, Salesforce, and ERP systems. You will architect, develop, and maintain inbound and outbound integrations that power critical business processes across Finance, Human Resources, and Operations. The ideal candidate brings deep Workato expertise, strong API and integration design skills, experience leveraging AI/ML APIs within integration workflows, and prior software development experience.

What you'll do:

• Integration Development
  • Lead the research, design, development, testing, and delivery of new integrations between ServiceTitan, Workday, Salesforce, ERP systems, and third-party applications using Workato as the primary integration platform.
  • Create technical design specifications, perform unit and system integration testing, and deploy and support all integrations end-to-end.
  • Understand business problems and build efficient, scalable solutions using Workato recipes, connectors, and callable recipes, supplemented by MuleSoft APIs and flows where appropriate.
  • Design and develop RESTful and SOAP-based API integrations, webhooks, event-driven architectures, and batch data processing workflows.
  • Build custom Workato connectors and actions using the Workato SDK when out-of-the-box connectors do not meet requirements.
  • Develop and maintain MuleSoft Anypoint APIs, flows, and DataWeave transformations for complex integration scenarios.
  • Collaborate with stakeholders to assess and document requirements, review designs, and define functional specifications.
  • Manage integration analysis, configuration, and deployment across development, staging, and production environments.
  • Lead integration projects with third-party vendors from discovery through design, development, testing, and implementation.
• Integration Administration & Operations
  • Proactively monitor inbound and outbound data integrations, system health, job execution, error rates, alerts, and notifications across Workato and MuleSoft environments.
  • Build and maintain robust error handling, retry logic, and alerting mechanisms within integration recipes and flows.
  • Participate in platform upgrades and release reviews for Workato and MuleSoft, identifying impact and enhancement opportunities associated with new features and connector updates.
  • Monitor, track, and resolve enterprise integration support tickets; collaborate with functional leads on escalated issues.
  • Create detailed integration specifications, field mappings, data transformation logic, and API documentation to support the full integration deployment lifecycle.
  • Research integration failures, perform root cause analyses, and report findings and remediation plans to management and business stakeholders.
  • Collaborate with functional leads, analysts, and system administrators on system operations, security, business processes, and how they relate to integrations.
  • Assume additional responsibilities as required.
• Technical Leadership & Architecture
  • Serve as the subject matter expert on the Workato and MuleSoft integration landscape, including recipe/flow patterns, connector capabilities, and platform best practices.
  • Maintain current knowledge of Workato and MuleSoft products, iPaaS industry trends, and agile methodology best practices.
  • Stay current with platform releases, new connectors, and features; evaluate their potential impact on existing integrations and recommend adoption strategies.
  • Be a strong contributor to the integration platform vision and drive team planning and architectural decisions.
  • Work with business stakeholders to identify problem areas, assess integration complexity, and determine overall project impact.
  • Develop and maintain the end-to-end enterprise integration strategy, including middleware selection, data flow governance, and API management.

  • Maintain and enhance reporting frameworks to support operational excellence and SLA compliance.
  • Translate business requirements into integration-driven reporting solutions and analytics.
• AI-Powered Integrations
  • Design and implement integration workflows that leverage AI/ML APIs (e.g., OpenAI, Anthropic Claude, Google Vertex AI) to automate data enrichment, classification, and decision-making within business processes.
  • Build intelligent document processing pipelines using AI services for extraction, summarization, and validation of unstructured data flowing through integration workflows.
  • Integrate natural language processing and generative AI capabilities into Workato recipes and MuleSoft flows to enable smart routing, automated responses, and content generation.
  • Collaborate with data science and engineering teams to operationalize ML models by embedding model inference calls into production integration pipelines.
  • Evaluate and adopt AI-powered features within Workato (e.g., Workato Autopilot) and MuleSoft to accelerate recipe development, improve error resolution, and optimize integration performance.
