Role Overview

We are looking for a Senior Backend Engineer to join our Data Fetching Team and take ownership of building, scaling, and optimizing our distributed web-data ingestion pipelines.

This role is focused on reliable large-scale data collection, web scraping, platform-specific fetchers (including TikTok and other modern social platforms), working with API and backend services powering our data intelligence products.

This is a hands-on, senior role with real ownership over architecture, execution, and technical direction.

Responsibilities

• Design, build, and maintain high-performance data fetching and scraping services for large-scale ingestion of public web and platform content.
• Develop and maintain platform-specific scrapers, especially for rapidly evolving ecosystems such as TikTok, X/Twitter, Instagram, YouTube, Telegram, and emerging platforms.
• Architect and optimize distributed scraping workflows (task queues, schedulers, rate-limit control, retries, proxies, error-handling, observability, monitoring).
• Build backend services in Python that power ingestion, normalization, parsing, and delivery of data to internal pipelines and storage layers.
• Collaborate with product, data engineering, and AI teams to ensure high availability, quality, and reliability of the fetched data.
• Contribute to existing re-usable components to enhance development velocity.
• Follow best practices in software development when implementing new and refactoring the existing codebase.

Requirements

• Strong expertise in Python, including async programming, object-oriented principles, and ORM strategies.
• Proven experience building production-grade web scrapers, crawlers, or platform data fetchers (preferably including TikTok or other modern JS-heavy platforms).
• Advanced knowledge of scraping techniques, including headless browsers (Playwright/Puppeteer), content extraction, and browser automation.
• Strong experience working with proxies, including rotation logic, tunneling, and pool management.
• Solid algorithmic thinking, ability to reason about complex workflows in a microservice world.
• Hands-on experience with relational databases and message queues.
• Hands-on experience with Docker, Kubernetes, and cloud environments like AWS and GCP.
• Strong communication skills and readiness to collaborate across engineering teams.

We Offer

• Opportunity to contribute to a mission-driven startup and support prestigious clients, including governments worldwide, enterprise clients, and leading NGOs in addressing information threats and tackling security challenges.
• Autonomy and freedom to drive experiments and bring your own ideas to life.
• Flexibility of fully remote work.
• Flexible, unlimited time-off policy.
