Data QA is an important function within Zyte. The Data QA team works to ensure that the quality and usability of the data scraped by our web scrapers meets and exceeds the expectations of our enterprise clients. 

Are you passionate about data and data quality and integrity?

Do you enjoy using Python and AI to analyze and manipulate data, detect data quality issues, and visualize your findings?

Are you highly customer-focused with excellent attention to detail?

Owing to growing business and the need for ever more sophisticated Data QA, we are looking for a talented Data Scientist to join our team. As a Zyte Engineer, you work on AI-based data wrangling, data manipulation, and data visualisation techniques and apply them in the verification and validation of data quality as it pertains to data extracted from the web.

Roles & Responsibilities:

• Understand customer web scraping and data requirements; map these requirements to custom AI-based data quality validation techniques, with a focus on achieving pre-established degrees of data quality and uncovering data quality issues.
• Draw conclusions about data quality by producing descriptive and evidence-based statistics, summaries, and visualisations.
• Supplement existing manual QA and schema validation techniques with AI-based data quality verification.
• Collaborate with developers to further troubleshoot and pinpoint solutions.
• Present findings and conclusions to stakeholders at various levels (other members of the QA department, developers, project managers, account managers, customers).
• Write high-quality, well-structured code that is maintainable and extensible.
• Manage code using GitHub, BitBucket and other version control approaches as applicable.

Requirements:

• Highly proficient in Python and the PyData stack. Minimum of 3 years (please provide code samples in your application - ideally pertaining to data analysis or Generative AI - via a link to GitHub or other publicly-accessible service).
• BS degree in Computer Science, Engineering, Mathematics, Statistics or equivalent.
• Up to speed on the latest advances in Generative  AI particularly as they pertain to process automation, web scraping/parsing, and data quality verification.
• Comfortable with Prompt Engineering and token/cost optimization. 
• Familiar with abstraction layers (MCP, Marvin, Langchain etc).
• Experience coding against the APIs of at least one of the Google, OpenAI, or Anthropic models.
• Experience in data quality visualization and the visualisation of data quality issues.
• Ability to work with very large datasets (into the millions of records).
• Strong knowledge of software QA methodologies, tools, and processes.
• Excellent level of written and spoken English; confident communicator; able to communicate on both technical and non-technical levels with various stakeholders on all matters of QA.
• Outstanding attention to detail.

Desired Skills:

• Prior experience in a Data QA role (where the focus was on verifying data quality, rather than testing application functionality).
• Familiarity with Jupyter and JupyterLab.
• Experience building your own dashboards.
• Experience with Spark, BigQuery, and other big data technologies.
• Previous remote working experience.

As a new Zytan, you will:

Become part of a self-motivated, progressive, multi-cultural team.
