Data Engineer

At iyzico, the Data Platform team builds the backbone behind analytics, reporting, and AI across one of Türkiye’s largest payment platforms. You’ll work on a large-scale distributed data warehouse and real-time CDC pipelines — at genuine scale, in a regulated environment. A growing part of this work is our governed, in-house LLM platform — used to turn natural language into trustworthy analytics, automate data workflows, and build data products that engineers and analysts can rely on. This is a role for engineers who want to own data problems end to end, from raw event to production.
What you’ll do
Build, operate, and own batch and streaming data pipelines end to end
Write and optimize SQL against a large-scale distributed PostgreSQL warehouse
Design and evolve data models and ETL/ELT processes
Develop and maintain orchestration with Apache Airflow
Build real-time data flows with Kafka and CDC
Own data quality, governance, and observability — the checks, monitoring, and alerting you actually trust
Investigate pipeline and data issues to root cause, and ship durable fixes
Help run the data platform itself: install, configure, and troubleshoot its components
Build on our in-house LLM platform: retrieval-augmented data pipelines, natural-language-to-SQL over the warehouse, and analytics automation — with correctness and governance built in
What we’re looking for
2-3 years of experience 
Strong SQL and query optimization
Solid grasp of relational databases and data modeling
Hands-on Python for data processing and automation
Working knowledge of ETL/ELT and pipeline design
Comfort in a Linux/CLI environment
Git, code review, and testing as part of your normal workflow
A problem-solver who can dig into unfamiliar systems independently
Ownership: you take a problem from investigation all the way to production
Nice to have
PostgreSQL / Citus at scale
Kafka, Debezium, or other streaming/CDC tooling
Airflow or another orchestrator
Data quality, monitoring, or observability tooling
Linux-based data platform administration
Experience with LLM/AI-based systems
Fintech or payments background
