* Deploy changes with Jenkins and GitHub Actions.


Qualifications

* Experience as a Data Engineer using SQL and Python.
* Exposure to DBT or similar data‑transformation tools.
* Exposure to Apache Airflow or similar tools for DAG creation.

Benefits

Enjoy fantastic perks such as private healthcare and dental insurance, a generous work‑from‑abroad policy, a 2‑for‑1 share purchase plan, an EV scheme to reduce carbon emissions, extra festive time off, and excellent family‑friendly benefits.

Work in a hybrid model: train to work from the office 60% of the time over a 12‑week period; also 28‑day work‑from‑abroad policy.

We are committed to creating inclusive workplaces and celebrate diversity in all its forms. We value gender, ethnicity, sexuality, disability, nationality and diversity of thought.
