About The Position

We’re a lean, in-office team that owns the stack end-to-end and builds reliable, well-crafted software to keep logistics moving. Current focus: maintain and improve the shipped Node.js/React customer portal on AWS (Terraform-managed infra, Postgres, GitLab for source control/CI-CD). Greenfield charter: plan and deliver GoLang backends with React/Typescript frontends for a modular TMS and other new projects on the same AWS/Terraform/Postgres foundation, ensuring these systems integrate with each other and the portal.

Requirements

Senior-level experience in GoLang and Node.js, plus strong React and Postgres expertise.
Broad proficiency with AWS services and Terraform/IaC.
Experience building and maintaining CI/CD pipelines (GitLab preferred).
Proven ability to build from the ground up with strong quality controls (testing, reviews, observability, security) and to integrate new systems with existing products.
Standard in-office hours in Pevely; no on-call expected.

Nice To Haves

Experience breaking monoliths into services/modules, designing API contracts, and handling data migrations.
Background with logistics/transportation or integrations with external partner APIs.
Familiarity building features that consume AI/ML APIs and services.

Responsibilities

Maintain and enhance the customer portal (Node.js/React) and build GoLang backends with React frontends for greenfield projects, including the TMS rewrite.
Plan and design module/service boundaries, contracts, and data ownership for microservices; choose sync/async integration patterns so new systems integrate cleanly with the portal and each other.
Implement and review scalable, observable, and secure services; tune performance and cost.
Own infrastructure-as-code changes with Terraform to keep environments consistent.
Build and maintain GitLab CI/CD pipelines to ensure reliable, predictable releases.
Write tested, maintainable code (unit/integration/e2e); participate in code reviews and architecture discussions.
Troubleshoot production issues; improve reliability and latency across services.
Partner with leadership across multiple departments to align roadmaps and third-party integrations.
Follow secure coding practices; partner with IT/Security on vulnerability remediation and compliance/data governance needs.
