Job Title: MuleSoft Developer
Location: Lenexa, KS
Contractor Work Model: Hybrid Onsite
Job Summary:
System One is seeking a MuleSoft Developer for a long-term, hybrid-onsite opportunity in Lenexa, KS. The MuleSoft Developer builds, enhances, and supports integrations across digital-transformation platforms using MuleSoft Anypoint and API-led best practices. This role is hands-on across the full API lifecycle—design, development, testing, deployment, monitoring, and optimization—and works closely with business users, BAs, and system owners to deliver secure, resilient, reusable integrations.
Responsibilities
- Design, develop, and maintain real-time/near-real-time APIs and ETL-style data integrations using MuleSoft (CloudHub/CloudHub 2.0) and reusable components aligned to API-led architecture.
- Configure and support integrations for Salesforce, ServiceNow, NetSuite, Dayforce, and internal applications.
- Build and optimize API flows, connectors, mappings, and error-handling frameworks.
- Develop and enhance scheduled enterprise integrations and ensure high availability, performance, and reliability.
- Conduct detailed analysis of existing integrations to identify improvements in security, resiliency, and performance.
- Implement and support deployments using Azure DevOps Services (repos, branching, CI/CD pipelines) in alignment with DevSecOps practices.
- Unit test, validate, and release integrations across non-prod, production, and DR environments.
- Maintain documentation, mapping specs, and architectural standards; contribute to component reuse.
- Collaborate with fellow developers and SMEs to clarify requirements, troubleshoot issues, and ensure alignment with data and integration strategies.
- 4+ years of software or integration engineering experience (MuleSoft CloudHub required; Java/.NET/API background preferred).
- Strong hands-on experience with Anypoint Studio, API-led design, RAML/OAS, and MuleSoft deployment models.
- Experience with CloudHub/CloudHub 2.0 operational best practices (DLBs, SSL/TLS termination, custom domains, whitelisting, HA configuration).
- Familiarity with messaging technologies (RabbitMQ, Anypoint MQ, or ActiveMQ).
- Proven troubleshooting, performance tuning, and environment evaluation skills.
- Experience using Azure DevOps Services in Azure cloud for Git repos and CI/CD release pipelines.
- Strong documentation habits and ability to collaborate in cross-functional design sessions.
- Growth-oriented mindset with interest in progressing toward senior engineering or integration architecture roles.
