Backend Developer — Python / AWS / EDI X12

We are looking for an experienced Backend Developer to join our team and work on a transportation-domain platform with a strong focus on EDI integrations.

What you will do:

Develop and maintain backend services in Python.

Build and support integrations with external systems and partners.

Work with EDI/X12 messages, mappings, validation, and processing.

Develop asynchronous and event-driven services.

Work with AWS-based infrastructure and services.

Design and maintain APIs and integrations.

Troubleshoot integration and production issues.

Work closely with the rest of the engineering team on architecture and implementation.

Requirements:

Strong commercial experience with Python.

Experience with AWS.

Experience with backend APIs and system integrations.

Experience with message-driven/event-driven architecture.

Experience with relational databases.

Solid understanding of distributed backend systems.

Strong debugging and problem-solving skills.

EDI / X12:

Hands-on experience with EDI / ANSI X12 is highly important for this position.

Transportation-domain experience is preferred, particularly:

X12 214 — Transportation Carrier Shipment Status.

X12 210 — Motor Carrier Freight Details and Invoice.

Strong X12 experience from other industries is also highly relevant. For example:

Retail / supply chain: 850, 856, 810

Healthcare: 837, 835, 270/271

Other EDI-heavy domains

We are looking primarily for someone who understands X12/EDI concepts and has practical experience with message structures, parsing, validation, mapping, acknowledgments, trading-partner differences, and integration troubleshooting. Direct experience with 210/214 is a strong advantage, but solid X12 experience in another domain is transferable.

Nice to have:

NATS or another message bus; NATS preferred.

Transportation or logistics domain experience.

Direct experience with X12 210/214.

Rust.

Frontend/UI development experience.
