## About the Role

* 4+ years of professional programming experience, with strong expertise in Python.
 * Experience building and maintaining complex, production-grade systems.
 * Experience integrating third-party APIs (auth, rate limits, pagination, error handling).
 * Deep understanding of Python fundamentals: OOP, mutable vs. immutable types, concurrency (threads/async).
 * Solid experience with Linux-based development and production environments.
 * Working knowledge of SQL (we use PostgreSQL).
 * You enjoy a fast-moving organization where you have real impact and ownership.
 * Fluent English (written and spoken), we're a fully remote, async-friendly team.
 * Willing to complete a background check.

Nice to have

 * Experience with Redis, Docker, or CI/CD pipelines.
 * Experience in data integration, ETL/ELT, or martech/adtech APIs.
 * Experience working in a small, remote-first product company.

## Description

We're looking for a Senior Python Engineer to work on the core of our platform: Python services, API integrations, scalability, and production reliability.

A big part of the work is taming the complexity of 300+ third-party APIs, each with its own quirks in authentication, rate limits, pagination, and data formats and making the platform fast and reliable at scale.

What You'll Do.

 * Build, improve and optimize advanced services built with python that power data synchronisation, transformation across 300+ source APIs and 30+ destinations.
 * Develop new connectors and improve existing ones, handling auth flows, rate limiting, retries, pagination, and schema variations.
 * Improve scalability and reliability of production systems (performance, concurrency, monitoring, incident prevention).
 * Write well-tested code (pytest) and review merge requests from teammates.
 * Work in two-week sprints with room for shifting priorities, we stay pragmatic, not process-heavy.

Our tech stack

 * Python: Flask, threads, pytest / pytest-xdist, pylint
 * Redis, PostgreSQL
 * Linux, Docker, GitLab CI/CD
 * React + Redux on the frontend (not the focus of this role)
 * Taiga for sprint planning
