About the Role
We’re looking for a Software Development Engineer I to help build next-generation web crawling and data automation systems. You’ll work with modern tools like Puppeteer, Playwright, and LLMs to extract and process data at scale. This is a hands-on role where you’ll design, build, and optimize crawling pipelines, while learning from senior engineers and contributing to real production systems.

 

What You’ll Do

  • Build and maintain scalable web crawling and automation tools using Node.js, Python, or similar.
  • Use LLMs and browser automation (Puppeteer/Playwright) to adapt to complex, dynamic sites.
  • Develop reliable data pipelines to handle high-volume collection and processing.
  • Collaborate on CI/CD, monitoring, and automation for high availability systems.
  • Troubleshoot issues and optimize performance for crawling and data workflows.

 

What We’re Looking For

  • Experience coding in Typescript, Java, Python, or Go.
  • Knowledge of web scraping frameworks, browser automation, and REST APIs.
  • Familiarity with AWS services and databases (SQL & NoSQL).
  • Strong problem-solving skills and a growth mindset.

 

Nice to Have:

  • Exposure to LLMs/ML models for data extraction.
  • Experience with big data or distributed systems.
  • Previous work in e-commerce, retail, or digital data environments.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
