Senior Mulesoft Developer - Remote

About the role

This role is fully remote - candidates should be based in EST/CST timezones - and this is a long-term (multi-year) project contracted on a 6-month rolling basis. Hourly rates in the range of $70-80/h w2 or $75-90/h C2C.

Responsibilities

• Produce low-level design artefacts for MuleSoft integrations: sequence diagrams, flow specifications, error handling matrices, API contracts (RAML / OAS), and DataWeave transformation specs.
• Translate business and functional requirements into integration patterns, selecting the appropriate combination of system, process, and experience API layers.
• Define watermarking, retry, and idempotency strategies for polling and event-driven integration patterns.
• Participate in architecture reviews; identify and raise design risks before implementation begins.
• Contribute to and enforce integration development standards, including error handling conventions, logging structure, correlation ID strategy, and naming conventions.
• Design, build, test, and deploy MuleSoft integrations across the full Anypoint Platform stack: CloudHub 2.0, API Manager, Runtime Manager, Anypoint MQ, and Anypoint Exchange.
• Write expert-level DataWeave 2.x transformations covering complex JSON, XML, CSV, and flat-file mappings, including XPath and XSL/T for legacy formats.
• Implement production-grade error handling: technical retry policies, dead-letter queue patterns, circuit breakers, error logging, and structured incident escalation (e.g. ServiceNow).
• Write MUnit test suites with meaningful coverage of error paths, transformation edge cases, and connector behaviour — not just happy-path flows.
• Build and maintain CI/CD pipelines for MuleSoft using Maven, Jenkins (or equivalent), and Git branching strategies aligned to the team's release model.
• Configure Anypoint Monitoring for production flows: flow-level metrics, distributed tracing (OTEL), custom metrics, log search, and alert routing.
• Configure and maintain Anypoint Platform infrastructure: VPCs, dedicated load balancers, shared/private CloudHub spaces, API policies (OAuth, JWT, rate limiting, IP allowlisting), and SLA tiers.
• Manage API proxies, client registrations, and access control via API Manager; maintain Client ID and Secret hygiene across all registered applications.
• Support production integrations on a rotational on-call basis; lead root cause analysis for failures and own remediation to completion.
• Onboard integrations into Anypoint Exchange as reusable, discoverable assets consistent with a C4E operating model.
• Collaborate with Solution Architecture to shape integration design decisions; contribute to Architecture Decision Records (ADRs) where implementation choices carry architectural significance.
• Review integration designs and code produced by peers; provide specific, constructive feedback.
• Provide technical guidance to less experienced developers; support knowledge transfer and uplift across the team.
• Produce and maintain integration documentation: flow specifications, runbooks, operational guides, and API catalogues.

Essential Skills and Experience

• 5+ years of hands-on MuleSoft development in enterprise production environments, with demonstrable end-to-end ownership of integrations from design to live support.
• Proven ability to produce low-level design artefacts — not just implement against designs produced by others.
• Expert-level DataWeave 2.x: complex transformations, recursive functions, type coercion, error handling within transformations, and performance-aware mapping.
• Deep, hands-on experience with Anypoint Platform: CloudHub 1.0 and 2.0, API Manager, Runtime Manager, Anypoint MQ, Anypoint Exchange, and Anypoint Monitoring.
• Strong command of integration patterns: watermarking, idempotent consumers, scatter-gather, content-based routing, saga/orchestration, and event-driven messaging.
• Experience designing and implementing production error handling: retry policies, DLQ patterns, circuit breakers, structured error logging, and operational escalation flows.
• Hands-on MUnit experience — you write tests as part of delivery, not retrospectively.
• CI/CD experience for MuleSoft: Maven, Jenkins or equivalent, Git branching models, and automated CloudHub deployment.
• CloudHub platform configuration: VPC design, dedicated load balancers, shared and private spaces, API policies, and SLA tier management.
• Solid SQL and relational database fundamentals; experience with Azure SQL or equivalent.
• Experience with at least one major SaaS integration: Salesforce, Workday, ServiceNow, Coupa, or equivalent.
• Strong understanding of SOA, REST, HTTP, JSON, XML, and API-led connectivity principles.
• Strongly Preferred:
• MuleSoft Certified Developer Level 1 or Level 2. MuleSoft Certified Integration Architect is a significant differentiator.
• Experience with event streaming platforms: Kafka, Redpanda, or Anypoint MQ at scale — including topic design, consumer group management, and dead-letter topic handling.
• Experience with cloud data platforms (Azure, AWS, Snowflake) and polling-based consumption patterns including watermark state management.
• Experience with Anypoint Monitoring Telemetry Exporter and OpenTelemetry-based trace forwarding to external observability platforms (Datadog, Splunk, or equivalent).
• Experience in financial services, insurance, reinsurance, or other regulated environments where auditability and error traceability are non-negotiable requirements.
• Familiarity with Azure infrastructure: Azure SQL, Azure Service Bus, Azure API Management, or Azure Functions as integration adjacents.
• Experience in a C4E or Centre of Excellence model: contributing to shared standards, reusable assets, and developer enablement.

Qualifications

• Bachelor's degree in Computer Science, Information Systems, Software Engineering, or equivalent combination of education and demonstrable experience.
• MuleSoft certification preferred (Developer Level 1/2 or Integration Architect).
• 8+ years overall professional software engineering experience, with at least 5 years specialising in MuleSoft.
• Experience working in Agile/Scrum delivery environments with regular sprint ceremonies, story estimation, and iterative release cadences.
