Staff Data Engineer - Enterprise Platform, AI foundations

As a Staff Data Engineer, you will be tasked with building, scaling, and modernizing our enterprise data platform across modern data engineering, analytics enablement, governance, and AI-ready data foundations. In this role, you will own and improve the trusted data foundation supporting executive reporting, analytics, revenue operations, product insights, customer reporting, finance, GTM, and operational workflows across the company. You will partner across technical and business teams, and have the opportunity to shape how data engineering scales in an AI-enabled enterprise environment at petabytes scale - a high-impact role offering meaningful platform ownership and broad business visibility.

What Will You Do?

Primary responsibilities include:

• Build, maintain, and troubleshoot production-grade data pipelines across source systems, cloud data platforms, and business-facing data products, where you'll deal with datasets at petabytes scale.
• Support and improve critical data workflows using BigQuery, GCP, Kestra, Nexla, DataHub, Looker, Tableau, and Workato across Salesforce, billing, ARR, customer data, and finance domains.
• Improve data quality, observability, freshness monitoring, schema validation, reconciliation, alerting, and operational reliability for critical datasets.
• Participate in production support for business-critical data workflows, including incident response, root-cause analysis, and runbook development.
• Strengthen data governance and discoverability through metadata management, lineage, ownership, certification, metric definitions etc.
• Partner with Analytics, BI, Product, Finance, GTM, IT, Security, and Engineering stakeholders to deliver trusted datasets, AI-ready data foundations, and scalable data solutions.
• Leverage AI tools responsibly to increase engineering productivity, including SQL support, Python development, debugging, testing, and operational analysis.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

• Advanced SQL and Python proficiency for building, optimizing, troubleshooting, automating, and testing data pipelines across large datasets.
• Proven experience building and supporting batch or near-real-time ingestion pipelines using tools such as Nexla, Workato, Fivetran, APIs, or custom pipelines.
• Must-have: hands-on experience with cloud-based data stack - such as GCP and BigQuery (preferred) or comparable alternative in AWS ecosystem (and its services like Redshift, Athena etc.); including production dataset management, performance tuning, IAM, service accounts, and dev/prod environment separation.
• Experience with workflow orchestration tools such as Kestra, Airflow, dbt Cloud, or similar, including scheduling, dependencies, retries, and failure handling.
• Deep understanding of dimensional modeling (facts/dimensions, SCDs) and data quality/reliability practices (reconciliation, schema validation, freshness monitoring, runbooks).
• Familiarity with metadata management, lineage, data catalogs, semantic layers, and engineering best practices (Git, CI/CD, testing, code reviews).
