Role
Who you are
- We're prioritizing strong software engineering fundamentals over deep crawling-specific experience. The right candidate is a great engineer first; the domain can be learned on the team
- Software Engineering Fundamentals
- 5+ years of professional software engineering experience building production systems
- Strong CS fundamentals: algorithms, data structures, concurrency, distributed systems
- Proficiency in Java and/or Python
- Track record of owning features end-to-end from design through deployment and operation
- Comfortable making sound architectural decisions at the component level
- Data Engineering
- Hands-on experience with cloud data warehouses such as BigQuery or Snowflake
- Experience designing and operating large-scale ETL/ELT pipelines
- Experience with orchestration tools such as Apache Airflow
- Experience with streaming or event-driven systems such as Apache Kafka
- Cloud and Infrastructure
- Production experience on GCP (preferred) or AWS; multi-cloud exposure is a plus
- Hands-on experience with Kubernetes (GKE/EKS) for distributed workloads
- Familiarity with infrastructure-as-code tooling such as Terraform
- Background and Mindset
- Strong communicator who can explain technical decisions clearly
- Comfortable operating in ambiguity and iterating quickly
- Bias toward action and pragmatic problem solving
- Self-starter who thrives in fast-paced, evolving environments
- Experience working in a B2B data company or data-as-a-product environment
- Core Technical Stack
- Java and Python
- Apache Kafka
- GCP (BigQuery, GKE, Vertex AI)
- Snowflake and Starburst/Trino
- Terraform
- Scrapy and web scraping frameworks
- Proxy management systems
- Distributed systems and Kubernetes
- Apache Airflow
- Large-scale ETL pipelines
- Ideal Candidate Profile
- 5+ years of software engineering experience
- Experience operating systems that process meaningful volumes of data
- Strong CS fundamentals (algorithms, data structures, distributed systems)
- Excellent communicator who can explain complex ideas to diverse audiences
- Passion for solving hard problems and building elegant, scalable systems
- Experience working in a B2B data company or data-as-a-product environment is a strong plus
Desirable
- Experience with web crawling at scale (Scrapy or similar frameworks)
- Familiarity with proxy infrastructure, rotation strategies, or anti-bot evasion techniques
- Experience extracting structured and unstructured web data from diverse site architectures
- Knowledge of SERP (Search Engine Results Page) extraction
- Comfort with AI/LLM-based extraction approaches, applying language models to HTML at scale
What the job involves
- We're looking for a Senior Software Engineer to join our Web Data team and help build the next generation of ZoomInfo's web crawling and data extraction infrastructure
- This is a hands-on engineering role with high impact. You'll work alongside experienced engineers building large-scale crawling and extraction systems that process billions of pages. Your day-to-day will involve solving real distributed systems problems, writing production code, and shipping features that directly impact data quality across the platform
- You'll partner with a dedicated people manager who handles HR and administrative responsibilities, a product manager who connects business needs with technical work, and a senior manager who removes roadblocks and supports career growth. Your focus is on engineering execution, technical excellence, and collaboration
- As a Senior Software Engineer, you'll contribute to enterprise-scale crawling and extraction platforms that process massive volumes of web data
- You will:
- Design and implement components of scalable, fault-tolerant web crawling and extraction pipelines
- Write clean, production-grade code in Java and Python
- Build and operate ETL/ELT pipelines for large-scale data extraction and transformation
- Work with cloud infrastructure on GCP and AWS, primarily on GKE
- Improve observability, reliability, and operational excellence across the systems you contribute to
- Partner with product and data science teams to deliver impactful solutions
- Contribute to code reviews, documentation, and knowledge sharing across the team
- Stay current with evolving web technologies, anti-crawling mechanisms, and AI-powered extraction approaches
- This role sits at the heart of ZoomInfo's data platform. You'll contribute to the infrastructure that powers our business intelligence products and help shape how web data acquisition is done at ZoomInfo, while working at massive scale with cutting-edge technologies
- You'll be joining at a pivotal moment: the team is growing, the ambition is high, and there's real opportunity to make a lasting impact and grow into deeper technical leadership over time
Our take
It was only a few years ago when B2B sales teams relied on warm introductions and contact books. Now, cloud-based CRM, automation and Big Data are critical tools for any selling process. ZoomInfo’s B2B contact base has played a massive part in that journey.
The company primarily helps salespeople find potential customers. Crucially, ZoomInfo then leverages technology to help make that approach as successful as possible. Think contact details of the most likely budget holder at that company, signals for when and how to approach and crucial updates on the company’s fortunes.
ZoomInfo has grown significantly over the previous few years and is now shifting its approach to pursue more inorganic growth through mergers and acquisitions, acquiring several companies in 2022, including the job recruitment website Comparably.
The risk for ZoomInfo is that these moves represent expansion beyond its traditional strengths in top-of-funnel customer acquisition. The company will need to ensure that it maximises synergies in order to win in these markets. The company has expanded operations in India and is set to see further expansion, as indicated by its appearance on the Fortune Future 50 list of robust and growing companies in 2023.
