What are the responsibilities and job description for the Senior Web Scraping Engineer — Labrynth position at Infinity Constellation?
Stack @ Labrynth: GCP
At Labrynth, we’re a Silicon Valley startup building next-generation Hermeneutical-Agent systems — AI that can read, reason, and execute on the world’s most complex regulations.
Our Application Validator is live, performing audit-grade, evidence-grounded compliance checks. Next, we’re expanding the Application Generator to create regulator-ready drafts backed by verified data and citations.
You’ll help shape both — advancing safety, evaluation rigor, latency, and cost-efficiency across large-scale, production AI systems at the edge of applied research and real-world impact.
Our mission is to transform bureaucratic and complex processes using AI and automation, turning them into fast, transparent, and scalable pipelines. We are a spin-off from the world's largest AI Model Trainer - Invisible Technologies and are backed by the Infinity Constellation group. We already work with enterprise clients, governments, and large-scale projects, so you will have a real impact accelerating major developments.
About The Role
We are looking for a Senior Web Scraping Engineer to design, build, and operate large-scale data collection systems. You will be responsible for developing robust scrapers using tools such as Selenium, Beautiful Soup, Playwright, Scrapy, etc., and for creating automated workflows in the cloud that run reliably on a schedule, generate logs, and surface failures proactively.
You will also experiment with and apply LLM-based techniques to improve scraping robustness and data extraction quality.
Key Responsibilities
- Python
- Pydantic/PydanticAI
- Docling
- Django
- Cloud Run
- LLMs
- GitHub
- Clickup
- Selenium

Key Responsibilities
- Design, implement, and maintain web scraping pipelines for a wide variety of websites and data sources.
- Build scrapers using tools and frameworks such as Selenium, Playwright, BeautifulSoup, Scrapy (and similar libraries) with a focus on reliability, performance, and maintainability.
- Create automated workflows for scraping and data processing:
- Containerize scraping jobs (e.g., using Docker).
- Deploy and orchestrate them in the cloud (e.g., AWS, GCP, Azure).
- Configure scheduling (e.g., run daily/weekly/hourly) and dependency management.
- Implement monitoring, alerting, and logging:
- Capture detailed logs for each job run.
- Track job statuses and failures.
- Implement notifications/alerts when a scraper breaks or a website changes.
- Handle anti-bot measures (proxies, captchas, rate limits) and design scrapers that are resilient to layout and structure changes.
- Work closely with data engineering / product / ML teams to understand data requirements and ensure data quality.
- Utilize LLMs (Large Language Models) to:
- Parse and extract structured information from messy HTML or semi-structured content.
- Increase robustness of scrapers to frequent UI/DOM changes.
- Prototype new scraping / extraction strategies using LLM APIs.
- Write clean, well-tested, and well-documented code, and contribute to best practices, code reviews, and tooling for the team.
- Continuously improve the scraping platform, including performance optimizations, standardization, and reusability of components.
- 3 years of professional experience working with web scraping or data collection at scale.
- Strong proficiency in Python and common scraping libraries/frameworks such as:
- Selenium, Playwright, BeautifulSoup, Scrapy (or similar).
- Solid understanding of HTML, CSS, JavaScript, HTTP, and browser behavior.
- Experience building automated, production-grade workflows:
- Orchestrators / schedulers (e.g., Airflow, Prefect, Dagster, or similar).
- Building ETL/ELT pipelines and integrating with databases, data warehouses, or storage (e.g., PostgreSQL, BigQuery, S3, GCS).
- Hands-on experience with cloud platforms (AWS, GCP, or Azure), including:
- Deploying and running scheduled jobs.
- Managing infrastructure-as-code or similar deployment processes.
- Strong experience with logging, monitoring, and alerting:
- Ability to design logging for scraping jobs and to debug failures from logs.
- Familiarity with tools like CloudWatch, Stackdriver, ELK, Prometheus, Grafana, or similar.
- Experience with containers (Docker) and familiarity with CI/CD workflows.
- Exposure to LLMs (e.g., OpenAI, Anthropic, etc.) for tasks like parsing, information extraction, or automation.
- Strong problem-solving skills and the ability to debug complex, dynamic websites.
- Comfortable working in a fast-paced environment, with good communication skills in English.
- Experience with Kubernetes or other container orchestration systems.
- Experience dealing with large-scale crawling, distributed scraping, and high-concurrency systems.
- Familiarity with handling CAPTCHAs, rotating proxies, and headless browsers at scale.
- Background in data engineering
- Contributions to open-source web scraping tools or frameworks.
- Remote-first; primary collaboration in Americas time zones with ~5 hours overlap.
- Fully remote, flexible hours
- Payment in USD (contractor/freelance basis)
- Work on a global team, with real-world challenges and rapid growth opportunities
