We gain momentum by identifying business opportunities, getting involved, and bringing promising, large-scale projects to life. We rely on our teams' creativity and engagement to help us succeed and diversify our projects.

We are currently looking for a Senior Developer whose role is designed for a backend-focused expert who leads Nordik's evolution toward a robust, scalable, cloud-based data ecosystem. The position elevates our data maturity through strong engineering, automation, and architectural leadership—aligned fully with the Level 3 senior expectations from the original Full Stack JD but tailored to your required specialization.

Join us

You are passionate about data, integrations and development and want to contribute to exceptional projects?

Join the Groupe Nordik team

Work with like minded professionals who use their creativity and talents for one of the most dynamic, fast-growing companies in the region.

What you will do:

As a Senior Developer (Level III) specializing in data engineering, integrations, and cloud data platforms, you will architect, design, and deliver robust backend systems, data pipelines, and database-driven applications that power Groupe Nordik's operational and analytical ecosystems.

Unlike a full-stack profile, this role is backend-centric, with deep expertise in SQL/NoSQL databases, ETL/ELT workflows, data modeling, data warehousing, and integration patterns. You will serve as a technical lead, mentor developers, and drive best practices for data quality, scalability, and reliability.

Your work will directly influence Nordik's data strategy and ensure our systems, analytics, and integrations operate smoothly across multiple environments.
