In this role, you will design, develop, and support secure, reliable integrations using modern technologies including .NET, Azure, CoreWCF, Event Hubs, Kubernetes, and Terraform.
This opportunity is ideal for someone who enjoys solving complex technical problems, working with event-driven systems, and supporting mission-critical operations in a fast-paced environment.

About PTI – Where the RIGHT way is the SAFE way:

Professional Transportation, Inc. has been providing crew transportation services for railroads since 1980 and has an industry reputation for providing quality, reliable, and safe crew transportation services. Much like a shuttle service, PTI receives around-the-clock requests from our railroad customers to pick up and drop off train crews.


PURPOSE OF JOB:

This position is a non-supervisory role responsible for the design, development, and ongoing support of business-to-business (B2B) integrations between United Companies and its Class I railroad customers. The primary focus is building and maintaining the web services, messaging pipelines, and data exchanges that power trip order intake, status reporting, and operational visibility for partners. Working independently and alongside a Scrum team, this role interfaces with internal analysts and external technical counterparts at partner railroads to deliver reliable, secure, and documented integrations in accordance with United Companies’ standards and guidelines.


Why Join PTI?

  • Multiple health plan options, including medical, dental, vision, and supplemental insurance
  • Paid vacation, sick time, and holiday pay
  • 401(K) retirement plan for your future
  • Discounted cell phone plans with Verizon and AT&T

  • Design, develop, and maintain B2B integrations with Class I railroad customers, including trip order intake, status updates, and event-driven messaging.
  • Build and support SOAP/WSDL web services using CoreWCF on modern .NET, including request/response and one-way messaging patterns, with well-defined service and message contracts.
  • Implement and maintain OAuth2 and JWT Bearer authentication flows for server-to-server integrations, with secrets managed through Azure Key Vault.
  • Develop and support event-driven integration pipelines using Azure Event Hubs (Kafka surface), including producers and consumers with appropriate retry, idempotency, and dead-letter handling.
  • Follow the complete Software Development Life Cycle (SDLC): requirements, analysis, design, coding, testing, documentation, implementation, and maintenance.
  • Write and review specifications for integration components of simple to moderate complexity, and collaborate with external railroad technical counterparts to finalize interface contracts.
  • Fully document integrations, message contracts, error handling, and operational runbooks. Assist in maintaining departmental standard operating procedures (SOPs) and maintenance operation protocols (MOPs).
  • Contribute to design, code, and test reviews.
  • Perform unit, integration, and performance testing, and report results and recommendations to project lead(s).
  • Support production integrations, including monitoring, debugging, incident response, and root-cause analysis of integration failures.
  • Participate in the deployment pipeline using Azure DevOps, including containerized deployment to Kubernetes and infrastructure provisioning via Terraform.
  • Provide meaningful feedback for schedule development on specific code; deliver quality code on schedule.
