We're hiring a Senior Full-Stack Developer to join our team in Aarhus

Build the platform that brings AI agents to ecommerce teams

We're looking for an experienced full-stack developer who can bridge the gap between powerful backend capabilities and intuitive user experiences.

This isn't about churning out features - you'll be architecting and building the platform that enables ecommerce teams to harness AI agents, manage massive datasets, and gain transparent insights into their operations.

You'll work on challenging problems:

real-time data tables handling 100k+ records, complex state management, seamless backend integrations, and interfaces that make advanced AI capabilities accessible to non-technical users.

This is a role for someone who thinks in systems, moves fast, and wants to shape both technical direction and user experience.

Join us on our growth journey

At Cernel, we're bringing the AI revolution to ecommerce by building the intelligent backbone behind every item sold online.

We make ecommerce teams work smarter, faster, and with amplified abilities across the entire value chain - starting with what lies at the core: product data.

We design and develop a platform in-house that provides our customers with advanced AI capabilities on top of their existing data, allowing them to operationalize tasks and gain transparent insights into how their data is stored, enriched, and analyzed.

We facilitate data management and actionable insights at scale across all their systems.

As Senior Full-Stack Developer, you'll work closely with our CTO, taking shared responsibility for technical decisions, architecture, and delivering solutions that our customers depend on daily.
