Senior edi java full stack developer(10+ years) - remote

About the Role

We're looking for a Senior EDI Java Full Stack Developer to help build and scale our EDI and supply-chain visibility platform. You'll work across the full stack — from high-throughput, stateful stream-processing services that correlate millions of EDI documents a day, to the web UI our customers use to track their orders, shipments, and invoices in real time. This is a hands-on senior role: you'll own the design of complex features, dig into production issues at scale, and mentor other engineers, while staying close to the code.

The platform processes standard EDI transactions (X12 and EDIFACT) for large retailers, manufacturers, and logistics providers — think purchase orders, invoices, advance ship notices, and functional acknowledgments flowing through translation, correlation, and lifecycle tracking, all backed by distributed data stores and a modern web front end.

What You'll Do

Design, build, and maintain Java/Spring Boot microservices that ingest, translate, correlate, and track EDI documents end to end. Develop and tune stateful, high-volume stream-processing pipelines (Apache Flink / Kafka) that correlate related documents (PO ↔ ASN ↔ Invoice ↔ FA) and maintain document lifecycles. Build full-stack features: REST/Graph QL APIs on the back end and responsive, data-rich screens on the front end (React or Angular / Type Script). Work with a range of data stores at scale — Mongo DB (sharded), Postgre SQL, Elasticsearch, and Arango DB (graph) — including schema design, indexing strategy, and query performance. Deploy and operate services on IBM Cloud with Kubernetes and containerized workloads. Implement and troubleshoot EDI translation and mapping (X12 / EDIFACT), partner identifiers, and trading-partner onboarding. Investigate and resolve complex production issues — trace data through streaming state, databases, and search indexes; perform root-cause analysis; and deliver durable fixes. Own solution design for significant features: weigh trade-offs, document the approach, and drive it through implementation, review, and release. Write automated tests, participate in code reviews, and uphold engineering standards for reliability, performance, and security. Mentor mid-level and junior engineers, and partner with product, QA, and support teams to deliver customer-facing value.

Required Qualifications

10+ years of professional software development experience, with deep, recent work in Java (11/17+) and Spring Boot. Proven full-stack experience — production front-end work in a modern framework (React or Angular) with Type Script/Java Script, alongside back-end services. Hands-on experience with EDI standards and document types (X12 and/or EDIFACT — e.g., 850, 810, 856, 855, 997, 214) and EDI translation/mapping concepts. Solid experience designing and operating microservices and REST (and/or Graph QL) APIs. Strong experience with multiple data stores at scale — Mongo DB, Postgre SQL, Elasticsearch, and Arango DB (or comparable graph databases) — including performance and indexing considerations. Production experience deploying and operating on IBM Cloud (or a comparable cloud) with Kubernetes and Docker. Strong debugging and root-cause skills across distributed systems, and comfort operating in production. Experience with Git-based workflows and CI/CD. Excellent communication skills and a track record of technical leadership, design ownership, and mentoring.

Preferred / Nice to Have

Experience with stream processing (Apache Flink, Kafka Streams, or similar) and stateful streaming patterns. Deep experience with graph databases (Arango DB, Neo4j) for correlation/relationship modeling. Familiarity with B2 B integration protocols (AS2, SFTP, API-based) and trading-partner onboarding. Infrastructure-as-code and CI/CD pipeline ownership. Background in supply chain, logistics, or B2 B/EDI Saa S.

What Makes You a Fit

You're a seasoned engineer who's equally comfortable reasoning about distributed state in a streaming pipeline and polishing a customer-facing screen. You like untangling hard production problems, you write code others can build on, and you raise the bar for the team around you.
