Our requirements

  • At least 5-6 years of experience working as a Data Engineer, with a focus on Google Cloud Platform Data and Analytics.
  • Strong hands-on experience with Python, dbt, and Airflow
  • Solid working knowledge of BigQuery and the wider GCP data stack
  • Experience in data modelling, integration and security, with Terraform, GitHub and CI/CD as everyday tools
  • Strong problem-solving skills and the ability to get your bearings fast in an unfamiliar, undocumented environment.
  • Proven ability to work independently on complex projects, review other people's work, and mentor less experienced team members.
  • A consultant's mindset – versatile, comfortable moving between clients and domains. Most importantly: willing to learn and grow.
  • Full English proficiency is a must (B2/C1).

  • Familiarity with finance data – close cycles, reconciliation, reporting

  • Build and maintain data pipelines and transformations with Python, dbt, and Airflow
  • Model data across Data Warehouses, Lakehouses and Data Lakes within an established architecture
  • Take over existing environments – map what is there, document it, and make it reliable
    • Consult & Advise
  • Assess what exists and recommend improvements – your opinion counts, and you'll have an architect to set the direction
  • Review the work of other engineers and say clearly when something needs reworking
  • Stay up-to-date with trends and new technologies in data engineering
    • DevOps & Quality
  • Work with Terraform, GitHub and CI/CD pipelines across the full deployment lifecycle

  • Collaborate closely with the team, sharing knowledge and solving problems together
    • Company

    About the project

    We're looking for a senior Data Engineer who can step into an environment someone else built, work out how it really runs, and make it better. Most of our work is picking up existing platforms rather than starting from scratch. If you solve problems instead of waiting for instructions, like modern cloud tech, and are the person colleagues ask to check their work, keep reading.

    What we offer

    We're a growing company with global clients and big goals. That means challenges, variety, and real opportunities for you to grow. If you're ready to step up - we'll support you all the way.
  • Remote-first, flexible working model
  • Private healthcare, insurance and Multisport
  • Full working equipment provided
  • 1,000 PLN annual development budget for training, certifications, or conferences
  • Regular knowledge-sharing sessions and mentoring
  • Work with international clients from Switzerland, France, UK, the US, UAE, and more
  • A real team, where knowledge-sharing isn't just a slogan
  • Team integrations that help you connect without awkward icebreakers
