Role Description

Help us build our analytics system used by both internal teams and external clients, from the ground up. You will be a leading part of a high-performing platform data engineering team, which builds an online analytics platform providing insights and data for the world's largest brands and media platforms. This role involves working on high-scale distributed architecture, handling large-scale data processing at a petabyte scale, working with numerous advertising data sources from major platforms such as Google, Meta, and TikTok, developing systems that export massive amounts of reports with thousands of data points daily, and building robust APIs using Python and Java. You will integrate complex tools like data catalogs (e.g., Atlan, Open Metadata) and semantic layers (e.g., Looker, Cube.dev) and work with multiple data lakes such as Snowflake, BigQuery, and DataBricks. Additionally, you will leverage native tables and newly supported open formats like Iceberg and Delta to ensure maximum flexibility and minimize go-to-market time for new data products.

Who You Are

You are a passionate and experienced software engineer looking to take on your next major technical projects.  You enjoy learning the intricacies and nuances of a distributed system, and then elegantly and cleanly designing new technical implementations to organically grow that system to its greatest potential.  You can speak intelligently on the complex interaction between code choices now, their system tradeoffs, evolution, interaction, first order, future and second order effects. A constant learner, you’re a continuous contributor to the improvement in team skill level.  You’ve got the ability to take on individual assignments and complete them front to back.  You pride yourself on good architecture, writing and delivering high quality code.  

And most importantly, you enjoy sharing, reviewing, and teaching those practices to others.

What You Will do

• Be the technical system owner, responsible for producing a long-term technical vision, code quality, performance and observability.
• Learn multiple complex systems that use numerous modern cutting-edge technologies, such as Looker, Snowflake and Airflow.
• Design technical implementations to grow these systems
• Design and implement systems responsible for high concurrency access to large data sets
• Identify gaps, deficiencies and inefficiencies in the system. Propose and implement solutions.
• Help oversee technical implementations written by the rest of the team.  Ensure that team implementations are in line with the designs created by the team and aligned with DV best practices/agreed concepts, with an eye towards compatibility between features, design, implementation choices and best practices
• Be quick to fix issues that come up, and help to mentor and train others on the team
• Become a key contributor to feature scoping, technical implementation, and developer estimates
• Work with the Product Management team to understand requirements
• Be proactive about developer testing, and coding at all levels of a system of applications
• Test and optimize code developed both by you and by other team members
• Establish effective monitoring for automated system failure detection
• Continuously release your features using automated deployment tools and frameworks
