Core Responsibilities

Primary Functions

Lead the design and implementation of enterprise integration solutions using middleware platforms (e.g., Mulesoft, Dell Boomi, TIBCO, Azure Integration Services), ensuring connectivity between on-premise systems, cloud services, and third-party SaaS applications.
Define, document and enforce API standards and best practices (RESTful APIs, SOAP, GraphQL), including naming conventions, versioning, pagination, throttling, and error handling to ensure consistent developer experience and operational predictability.
Build reusable integration components and patterns (canonical data models, transformation libraries, retry and dead-letter strategies) to accelerate delivery and reduce technical debt across projects and teams.
Develop end-to-end data mapping and transformation logic (XML/JSON transformations, XSLT, JOLT, DataWeave) to guarantee accurate, performant and auditable data exchange between systems.
Design and implement secure authentication and authorization mechanisms for integrations (OAuth 2.0, JWT, API keys, mTLS) and work with security teams to ensure compliance with regulatory and internal security policies.
Own the lifecycle of APIs and integrations from requirements through design, build, test, deployment and production support, including maintaining backlog items and cross-functional sprint commitments.
Collaborate with product owners, business analysts and stakeholders to translate business processes into integration requirements, sequence dependencies, and define success criteria, SLAs and KPIs.
Implement robust monitoring, logging and alerting for integration flows (APM, ELK/ELK-like stacks, Splunk, CloudWatch, Datadog), and proactively resolve performance, latency and reliability issues.
Troubleshoot complex production incidents, perform root cause analysis, and implement permanent remediations while communicating clearly to stakeholders and documenting incident reports.
Create and maintain high-quality technical documentation (API specs, OpenAPI/Swagger, sequence diagrams, runbooks, integration design documents) to support on-call teams and knowledge transfer.
Design and manage message-based integration patterns using message brokers (Kafka, RabbitMQ, ActiveMQ) for decoupled, event-driven architectures and near real-time processing.
Lead integration testing efforts including unit, integration and contract testing, implement CI/CD pipelines for integration deployments (Jenkins, GitLab CI, Azure DevOps), and enforce automated quality gates.
Manage vendor and partner integrations — define onboarding plans, test harnesses, data mapping, error-handling processes and SLAs to ensure predictable go-lives and ongoing stability.
Conduct impact analysis for proposed changes to interfaces, orchestrations or canonical models to prevent service interruptions and to plan rollbacks or compatibility strategies.
Implement data governance controls for integration flows including data lineage, PII masking, encryption at rest/in transit and retention policies to support compliance and auditability.
Evaluate new integration technologies, middleware platforms, iPaaS and API management solutions; create proof-of-concepts and recommend technology adoption roadmaps aligned to enterprise strategy.
Estimate effort and provide reliable delivery timelines for integration workstreams and contribute to project budgeting and resource planning.
Coordinate cross-functional cutovers and release windows, ensuring rollback plans and consumer communications are in place to minimize business disruption during integration deployments.
Mentor and upskill junior integration engineers, share best practices, and lead code reviews to maintain code quality and architectural alignment across teams.
Maintain an integration backlog, prioritize work based on business value and technical risk, and ensure that integration deliverables map to business objectives and KPIs.
Enforce change control and configuration management for integration artifacts and environments, ensuring traceable deployments and environment parity across dev/test/prod.
Participate in vendor contract reviews and SLA negotiations from a technical perspective to ensure third-party obligations match enterprise operational and security requirements.
Perform continuous improvement reviews of existing integration telemetry, reduce operational toil (runbook automation, self-healing patterns) and drive cost optimizations in cloud-connected integration workloads.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Provide hands-on support during onboarding of new SaaS applications and coordinate data migrations and cutover validation.
Assist security and compliance teams with evidence and configuration details for audits related to integrations and APIs.
Run periodic integration health checks, dependency mapping and provide recommendations for architectural improvements.
Support business continuity planning for critical integration flows including DR test coordination and runbook validation.
Contribute to cross-team knowledge bases, training sessions, and developer onboarding for integration tooling and patterns.
Help define metrics and dashboards for business stakeholders to track integration performance, throughput and error rates.
