Job description

  • Design and maintain declarative extraction specifications-using Pydantic models, JSON schemas, or domain-specific languages-that describe exactly which fields to capture, their types, and validation rules.
  • Implement pipelines that translate these specifications into executable extraction plans, leveraging both classical (Scrapy, Playwright) and AI-augmented (LLM-based semantic parsing) backends.
  • Build reusable specification libraries for recurring data types (product prices, tariff codes, regulatory texts) to accelerate onboarding of new sources.
  • Design and implement autonomous data extraction agents that can make decisions about source selection, retry logic, and parsing strategies

Autonomous & Self-Healing Systems

  • Deploy self-healing spiders that automatically detect website layout changes and repair themselves using Model Context Protocol (MCP) servers (e.G., Scrapy MCP Server, Playwright MCP).
  • Integrate semantic extraction (Scrapy-LLM, custom LLM pipelines) to eliminate selector brittleness-spiders rely on field descriptions, not fragile XPaths.
  • Hands-on experience building AI agents and orchestration systems.
  • Orchestrate complex, multi-step browsing workflows with agentic frameworks (BMAD/TEA, AutoGPT-like agents) that reason about page state, adapt to anti-bot measures, and correct their own behaviour in real time.

Platform Thinking & Reusability

  • Move beyond one-off scrapers: build a component-based extraction platform where selectors, login handlers, and pagination logic are shared, versioned, and tested.
  • Implement monitoring, alerting, and automatic rollback for failed extraction runs.
  • Champion ethical crawling by design-rate limiting, robots.Txt respect, and compliance with GDPR/CCPA are built into the specification layer, not retrofitted.

Collaboration & Continuous Innovation

  • Partner with data scientists and domain experts to refine extraction specifications for complex, unstructured domains (e.G., legal texts, tariff classifications).
  • Evaluate and pilot emerging tools to push automation coverage beyond 90%.
  • Document and evangelise specification-driven best practices across the engineering organisation., * Contributions to open-source scraping or AI-automation projects.
  • Contributions to open-source scraping or AI-automation projects.
  • Familiarity with data privacy engineering (GDPR, CCPA) baked into specification design.
  • DevOps light - Docker, CI/CD for testing extraction specifications.
