• Support database administration activities, including user access, roles, permissions, performance, and maintenance

• Manage data deployments and contribute to CI/CD and infrastructure automation

• Investigate unfamiliar or poorly documented data sources and determine how systems, schemas, and integrations function

• Build data solutions supporting reporting, billing, customer, and operational use cases

• Integrate and work with data from internal, third-party, and legacy systems

• Partner with engineering, product, operations, and business teams to translate requirements into technical solutions

• Participate in code reviews and contribute to engineering standards and best practices

• Improve documentation, knowledge sharing, and overall platform reliability

Required Qualifications 

• Strong SQL skills, including complex joins, window functions, aggregations, NULL handling, and understanding of data grain

• Hands-on Python development experience, including maintaining code running in production

• Professional experience building or supporting production data pipelines

AI & Modern Engineering 

The engineering team incorporates AI-assisted tools into its development and problem-solving workflows. Candidates should be comfortable using AI tools thoughtfully to: 

• Investigate unfamiliar codebases, schemas, documentation, and systems

• Research and evaluate potential technical approaches

• Automate repetitive engineering tasks and workflows

• Improve development and troubleshooting efficiency

• Build custom scripts, tools, agents, or other AI-assisted workflows

Candidates should also understand the limitations of AI-generated output and be able to explain how they verify results, identify incorrect assumptions, and validate technical solutions before putting them into production.
