Employment Type: Full Time

Location: Warsaw (Remote)

Description

RubyPlay is a place where passion meets competence. Since 2017, we’ve made more than 200 innovative games and built more than 100 strong partnerships globally!

Proud to be:

• The Winner at BFTH Arena Awards — Best Online Casino Game
• Shortlisted for SBC Awards 2024 — Casino/Slots Developer of the Year
• A strong player on 10+ markets globally
• Beloved workplace for hundreds of specialists from 34 countries

We are now growing our team and looking for driven professionals ready to build their careers in a strong, international studio with a product that’s making waves worldwide. We’re hiring a Middle Data Engineer to build and operate reliable ELT/ETL pipelines on Snowflake + Airflow. You’ll consolidate data from databases, REST APIs, and files into trusted, documented datasets with clear SLAs and ownership.

Here’s How You’ll Make an Impact:

• Ingest data from RDBMS/APIs/files into Snowflake (batch/incremental; CDC when applicable).
• Build modular SQL/Python transformations; handle semi‑structured JSON; publish consumer‑ready tables/views.
• Orchestrate Airflow DAGs (dependencies, retries, backfills, SLAs) with monitoring and alerting.
• Ensure idempotent re‑runs/backfills; maintain runbooks and perform RCA for incidents.
• Tune performance & cost in Snowflake (warehouse sizing, pruning; clustering when justified).
• Partner with BI/Analytics to refine definitions and SLAs for delivered datasets.

What Makes You A Strong Candidate:

• 2–4 years building production ETL/ELT; strong SQL (joins, window functions) + Python for data tooling.
• Snowflake hands‑on: Streams/Tasks/Time Travel; performance & cost basics; JSON handling.
• Airflow proficiency: reliable DAGs, retries/backfills, SLAs; monitoring & alert routing.
• Data warehousing/modeling (Kimball/3NF), schema evolution; API integrations (auth, pagination, rate limits, idempotency).
• Git‑based CI/CD; clear written English; privacy/GDPR basics.

Nice to Have

• iGaming familiarity: stakes, wins, GGR/NGR, RTP, retention/ARPDAU, funnels; RG/regulatory awareness.
• AI & automation interest/experience: Snowflake Cortex for auto‑documentation, semantic search over logs/runbooks, or parsing partner PDFs (with guardrails).
• Exposure to cloud storage (GCS/S3/ADLS), Terraform/Docker, and BI consumption patterns (Tableau/Looker/Power BI).

Why You’ll Love It Here:

• Remote‑first flexibility — Work from anywhere with a setup for deep focus and work‑life balance
• Learning & growth — Development budgets and dedicated days to upskill and explore new areas
• Health & wellness — Medical coverage and well‑being budgets to help you feel balanced, strong, and supported
• Yearly bonus — Rewards based on company success and your impact
• Career growth — Vertical and horizontal opportunities to grow and advance
• Global team — Talented, diverse colleagues you’ll enjoy working with
