Core Responsibilities

Primary Functions

  • Design and implement enterprise integration solutions using Microsoft BizTalk Server, including orchestrations, receive/send ports, pipelines, maps, schemas (XSD) and custom pipeline components to meet complex business requirements and SLA targets.
  • Develop and maintain BizTalk schemas and map transformations (XSLT), building high-quality reusable maps that support versioning, extensibility and performance optimization.
  • Implement and configure adapters (HTTP, SOAP, WCF, FTP/SFTP, MSMQ, SQL, FILE, SMTP, LDAP, AS2) and custom adapters when required to connect BizTalk to disparate on-prem and cloud endpoints securely and reliably.
  • Create and maintain WCF services, SOAP and REST endpoints, and develop reliable service contracts and bindings to support synchronous and asynchronous integrations.
  • Build and maintain EDI/AS2 trading partner configurations, including X12/EDIFACT schemas, envelope settings, acknowledgements (997/CONTRL), trading partner protocols and partner onboarding processes.
  • Develop robust error handling, exception management, retry logic and compensating transactions in orchestrations and pipelines to ensure message integrity and predictable recovery behavior.
  • Author and maintain SQL Server objects (tables, stored procedures, views) used for tracking, correlation, reporting and custom persistence; optimize queries and indexes to improve BizTalk throughput.
  • Implement and enforce message security practices such as digital signatures, encryption, certificate management and secure transport channels to meet compliance and regulatory requirements.
  • Integrate BizTalk with monitoring, logging and alerting platforms (SCOM, ELK, Azure Monitor, Application Insights) and instrument solutions for end-to-end traceability and SLA reporting.
  • Create automated build and deployment pipelines for BizTalk applications using Azure DevOps, TeamCity or similar CI/CD tools, including MSI/package generation, bindings file management and environment promotion.
  • Perform capacity planning, performance tuning and load testing for orchestrations, pipelines and host instances to maintain predictable latency and throughput under peak conditions.
  • Provide design input and technical leadership for migration projects from legacy integration platforms to BizTalk or from BizTalk to Azure Integration Services, including feasibility analysis and hybrid integration designs.
  • Troubleshoot production incidents rapidly, lead RCA (root cause analysis), implement permanent fixes, and document mitigation steps and long-term corrective actions.
  • Develop custom .NET components, BizTalk pipeline components and helper libraries in C# to handle complex processing requirements that can't be solved by out-of-the-box capabilities.
  • Maintain and update BizTalk artifacts in source control, enforce branching strategies, and ensure code reviews and coding standards are followed across the team.
  • Collaborate with business analysts and product owners to gather integration requirements, translate business processes into message flows and provide estimates for implementation efforts.
  • Implement correlation and context propagation patterns to maintain message state across asynchronous and long-running processes, ensuring end-to-end transaction consistency.
  • Manage bindings, environment-specific configurations and deployment manifests to support multiple environments (dev, test, QA, staging, prod) and ensure reproducible deployments.
  • Design and implement data transformation and enrichment flows including lookups, reference data management and orchestration-based enrichment using databases, web services or cached datasets.
  • Onboard new trading partners and external systems: validate test payloads, configure security credentials, conduct test cycles, and produce partner integration documentation and runbooks.
  • Maintain up-to-date technical documentation including architecture diagrams, interface contracts, B2B partner guides, runbooks and support playbooks to enable operational continuity.
  • Coach and mentor junior developers on BizTalk best practices, design patterns, and troubleshooting techniques while promoting knowledge sharing and continuous learning within the integration team.
  • Coordinate with network, security and operations teams to plan maintenance windows, certificate rotations and platform upgrades with minimal service disruption.
  • Evaluate and recommend modernization approaches such as incremental migration to Azure Logic Apps, Azure Service Bus or API Management where appropriate while keeping hybrid interoperability.

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.
  • Assist in vendor evaluations and proof-of-concepts for integration tooling, adapters and third-party B2B gateways.
  • Provide on-call rotation support for integration platform incidents and participate in post-incident reviews to reduce recurrence.
  • Help maintain integration environment hygiene by applying patches, service packs and BizTalk cumulative updates in coordination with change control.
