• Master the current workflow (Python/SQL/Airflow).
• Establish a process for monitoring and maintaining existing integrations.
• Take over the process of creating new integrations.

Challenges for the first six months

• Optimize the data aggregation process according to the specifics of the new infrastructure.
• Take ownership of ETL support – resolve incidents, suggest improvements.

What we expect from you

• 2+ years of experience as a Data Engineer.
• Experience with SQL.
• Knowledge of one of the languages: Python / Java / Scala (we use Python).
• Experience with Spark and Databricks.

We offer

• Work format of your choice: fully remote from anywhere in the free world, as well as access to one of our offices if desired (Kyiv, Warsaw).
• Conditions that help you focus on performance: fair compensation that matches your skills and experience. We also provide equipment regardless of work format and location.
• Career growth through action: 80%+ of all leads at Kiss My Apps were switchers just 2–3 years ago. Your impact here isn’t defined by years on your resume — it’s defined by how quickly you learn, take responsibility, and own your career.
• Well‑being program: we care about the mental health of our team and provide access to individual or group therapy sessions with a corporate psychologist, as well as online yoga classes twice a week.
• Development and professional fulfillment: we host internal English speaking clubs with a native speaker, and offer opportunities to speak at internal and external events by Kiss My Apps. In addition, you’ll have an annual budget to cover up to 50% of the cost of professional conferences, educational events, and training.
• Additional benefits of your choice: We offer a fixed annual budget for you to decide how to spend — 50% coverage of health insurance, therapy, sports, or dental care. Plus, 40 days of paid vacation and sick leave with no date restrictions.
• Support during wartime: we provide everything needed for uninterrupted work, systematically support the Defense Forces, and participate in Ukraine’s recovery initiatives.

Important: there is an option to reserve positions for conscripts after a trial period, provided that they have properly executed military registration documents and the company has internal capacity, as determined in accordance with applicable law.

What the hiring process looks like

• Intro with a recruiter – a 45‑minute conversation about your expectations and the culture at KMA.
• Technical interview with Data Engineer and Non‑mobile department lead.
