From complex pick-and-pack operations to perishable shipping technology, ColdTrack delivers the best logistics solutions for cold and frozen eCommerce businesses - because perishables shouldn’t be late. Period.

ColdTrack Live is our core platform: real-time, operational software that powers temperature-sensitive fulfillment from end to end. From logistics to labeling to last-mile visibility, it’s built for performance, precision, and scale. We move fast, think critically, and expect our engineers to do the same.

We’re looking for a senior-level engineer who can architect, build, and maintain full stack applications that directly power those operations. This is not a junior or mid-level role. We need someone who has led technical initiatives, made system-level decisions, and shipped production-ready software at scale. You’ll join a sharp, fast-moving team where autonomy is expected and impact is visible.

You’ll work with modern Java backend, frontend frameworks like React with TypeScript, and real-time operational data from warehouse management systems and APIs like EasyPost. The systems you build will directly affect how our customers move temperature-sensitive goods across the country.

What You’ll Do

Build and maintain full stack features using Java and modern frontend frameworks (React, Angular, TypeScript)
Architect scalable systems and help set development standards
Integrate with third-party APIs (like EasyPost) and internal tools
Work with real-time operational data from scanners, WMS, and IoT sources
Collaborate across engineering, product, and design to shape technical direction
Participate in code reviews, mentor teammates, and unblock others
Contribute to sprint planning, technical roadmap, and system design discussion

What We’re Looking For

7-10+ years of full stack experience building modern, production-grade systems
Deep experience with Java, Spring Boot, RESTful APIs, and microservices
Strong frontend experience in JavaScript and frameworks like React, Angular or Vue
Comfort with SQL and NoSQL databases, and containerization (Docker, Kubernetes)
Experience working in cloud-native environments (AWS preferred)
Strong problem-solving, debugging, and communication skills
Self-directed and able to own end-to-end project delivery
