About the Company

We're looking for a Data Engineer to join our Data Platform team at Coinhako. Every dashboard, fraud signal, financial report and AI-driven analysis in the company depends on data being right. Our team runs the systems that make that true - the metadata repository, the ingestion and ELT pipelines, the warehouse, and the internal tools our teams use every day. This is a hands-on contributor role on a small team, working inside a platform direction that's already set. You'll own pieces end to end: a pipeline one week, an internal tool the next, a data-quality problem the week after. Some of it is systems that are already live and depended on - those become yours to run and improve. The rest is new. Crypto data does not behave. Upstream sources change shape without telling us. Numbers that look wrong are often correct, and numbers that look fine sometimes aren't. Most of the interesting work here is in knowing the difference - and building systems that hold up when you can't be sure.

Responsibilities

  • ● Write and run pipelines
  • ● Write and operate ingestion and ELT pipelines (Airflow / MWAA) bringing in transactions, product events and third-party feeds
  • ● Take a source we've never used and turn it into a table analysts trust
  • ● Keep pipelines healthy - including ones you didn't write
  • ● Contribute to guaranteeing the accuracy of our numbers
  • ● Add quality checks that stop bad data reaching reports, and make missing data visible instead of silent
  • ● Reconcile our numbers against independent sources
  • ● Investigate when a number looks wrong, and be able to say why it was - or wasn't
  • ● Contribute to the metadata layer
  • ● Add to and maintain the metadata repository that pipelines, apps and analytics rely on
  • ● Document datasets well enough that analysts and AI systems can use them without asking us
  • ● Contribute to the internal tools
  • ● Work on the backend and data layer behind the internal tools our teams depend on - the APIs they call and the metadata that drives them
  • ● Help integrate AI (LLM / RAG, agentic analysis) into the platform and its tools
  • ● Support the people who use it
  • ● Handle requests from analysts and stakeholders, and turn the repetitive ones into something self-service
  • ● -4 years in data engineering, backend, or platform engineering
  • ● Strong SQL and Python
  • ● Familiarity with cloud services (AWS preferred)
  • ● You understand the systems you've built - why they behave the way they do, what the trade-offs were, and what they cost to run
