Data Engineer - On-site Copenhagen

AI is changing how software gets built.

The data underneath it matters more than ever.

At Heyra, we build operational AI: systems, workflows, and data platforms that live in production from day one. We work with companies that are moving quickly and need solutions that improve the way they operate.

We’re looking for a Data Engineer who enjoys building things properly. Someone who can move through complex systems, shape clean architecture and create the foundations modern AI workflows depend on.

You’ll work closely with engineers, AI specialists, strategists and designers in a company where ideas move quickly and the distance from thinking to building is intentionally small.

What you’ll work on

• Building modern data platforms and pipelines

• Creating semantic foundations for AI systems

• Developing AI-powered workflows and agentic systems

• Helping clients move AI into real operational environments

• Working closely with both technical teams and decision makers

• Shaping how modern AI infrastructure is built in practice

Requirements

You probably have experience with

• dbt, SnowFlake, Databricks, Fabric, BigQuery or similar ecosystems

• SQL, Python and APIs

• Data modelling and warehousing

• GenAI, ML or MLOps workflows

• Complex systems and problem solving

Curiosity, taste and builder mentality matter just as much to us as specific tools or years of experience.

Why Heyra

We believe consulting needs to be rewritten. We are building a consultancy designed for the agentic era. We design, build and operate AI products that change how enterprises work, from problem to prototype to production.

Heyra brings together people from engineering, strategy, product, startup and creative environments. We keep teams small, collaboration close and momentum high. We care deeply about craft, speed and building things that work in the real world.

People here care about what they build. Good ideas move quickly. New technology gets explored early. There is room to shape both the company and the way we work.

We are around 45 people today, and we are only just getting started.

If this sounds like your kind of work, send us a short note about yourself together with your CV. We care much more about curiosity, energy and the way you think than polished applications.
