Job Opening: Backend Developer, Analytical Data (PHP + MySQL, complex queries)
Location: Remote
About the Company
We are a fast-growing product company in eSIM and digital roaming for travel. Our platform helps users around the world get mobile internet without plastic SIM cards — quickly, conveniently, and at a fair price.
We build products where decisions are data-driven: from monitoring connection quality and activation funnels to behavior analytics. That’s why it’s critical for us that production data is transformed into clean, structured, analysis-ready datasets.
About the Role
We’re looking for a developer who will take ownership of processing and preparing analytical data. Your mission is to extract and transform data from the main database, preparing it for reports and decision-making.
You’ll write complex SQL queries, aggregate, filter, and group data, and set up daily jobs for synchronization and processing. You will build processes end-to-end — from raw sources to ready-to-use data structures.

-
Daily processing and transfer of data from the production database.

Requirements
-
Excellent knowledge of MySQL and ability to write efficient SQL queries.
-
Confident proficiency in PHP.
-
Experience working with large data volumes and complex joins.
-
Basic understanding of reporting systems or data warehouses.
-
Python is a big plus (for utilities and automation).
-
Ability to work independently and propose solutions.
What We Offer
-
Fully remote work format.

Direct product impact: your processes and scripts will power reports and decision-making.
-
Strong team and fast feedback cycles.
