NOW HIRING – Integration Engineer!

Join PTI as a Integration Developer and help build the systems that power communication between PTI and Class I railroad customers.

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.

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.

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.
