About KNNX

KNNX is changing how companies manage their supply chains. Our technology gives businesses precision control over freight and logistics, helping them avoid costly risks and run their operations with confidence.

In the last six years, we've become a trusted partner to more than 600 companies, including some of the largest retailers in the world. Our flagship product, KNNX Freight, is part of a broader ecosystem powered by our Enterprise Transaction Assurance (ETA) platform. ETA connects siloed systems across the supply chain, creating a single version of the truth for every transaction. This enables our clients to work with cleaner data, make faster decisions, and eliminate inefficiencies at scale.

At KNNX, you'll be part of a team that's building technology with a real impact on global supply chains. We value people who are curious, collaborative, and driven to solve complex problems.

Role Overview

We're looking for a senior full-stack developer to lead the

end-to-end development

and iteration of web applications, supporting the discovery of new products and markets for KNNX, working across the stack (Node.js/Express backend and Vue.js frontend). You will design system architecture, implement new features, ensure code quality, and mentor junior developers. This role is pivotal in bridging front-end and back-end to deliver high-quality products.

Ideal Candidate

You're a technically adept builder and systems thinker who thrives at the intersection of code and business outcomes. You appreciate both the strategic complexity of freight and the technical demands of SaaS platforms, and you're energized by the challenge of solving real-world logistics problems with elegant, scalable software. You take pride in owning the full product lifecycle, from early-stage discovery and architecture to hands-on development, deployment, and continuous iteration, adapting quickly as requirements evolve and solutions take shape. You care deeply about clean code, thoughtful design, and mentoring others to raise the bar for technical excellence.
