Senior AI Analytics Engineer

THE OPPORTUNITY

We are hiring a Senior AI Analytics Engineer to our Global Analytics team in Brasil - Remote!

As a Senior AI Analytics Engineer within Wellhub's ever-growing Global Analytics team, you'll take a central role in driving a data-driven culture and executing on our analytics strategy. This technically focused role sits at the intersection of data modeling, software engineering, and applied AI — requiring deep hands-on skills across all three. You will be instrumental in building and maintaining the governed data foundations that power AI-driven analytics across the company, ensuring that every tool and workflow draws from consistent, trustworthy definitions of our most critical business concepts. This includes developing high-quality data models, building automated governance pipelines, and designing the context structures that make AI-powered self-serve analytics accurate and scalable at Wellhub. You will partner with teams across the product and business to translate complex and often loosely defined data needs into reliable, AI-ready assets that stakeholders can trust.

YOUR IMPACT

• Build and maintain high-quality LookML models, ensuring the semantic layer is enriched with accurate labels, descriptions, synonyms, and business logic that AI tools — including Looker Conversational Analytics and external LLMs — can reliably consume;
• Design and configure domain-focused Data Agents with well-structured instructions, Golden Queries, and scoped context governance to deliver accurate and trustworthy conversational analytics;
• Develop and maintain CI/CD pipelines that automate metadata governance, including AI-assisted description generation, DDL synchronization, and semantic consistency checks;
• Build reusable AI skills, tools, and workflows that allow analysts and stakeholders to interact with governed data through natural language interfaces;
• Partner with Data Analysts, Data Engineers, and business stakeholders to translate vague or poorly defined business questions into well-defined, measurable data models and agent instructions;
• Identify opportunities to improve the quality and reliability of AI-generated insights by improving context structure, metadata coverage, and semantic layer precision;
• Develop recommendations and drive improvements to data standards, processes, and definitions;
• Contribute to cross-team guidelines and best practices for responsible AI usage with data.

WHO YOU ARE

• 3-5+ years of relevant work experience in analytics engineering, data modeling, or a closely related field;
• Excellent SQL skills required;
• Proficiency in Python — comfortable writing and maintaining production-grade scripts and automation pipelines, not just exploratory code;
• Hands-on experience with a semantic layer or BI modeling tool (LookML/Looker, dbt Semantic Layer, or equivalent);
• Practical understanding of how Large Language Models consume structured context: field-level metadata, descriptions, synonyms, and prompt design;
• Experience designing context for AI agents: writing system instructions, scoping agent boundaries or contributing to agent skill frameworks;
• Experience building or maintaining CI/CD pipelines for data artifacts (GitHub Actions, dbt CI, or similar);
• Significant exposure to complex data pipelines, data modeling, and data architecture;
• Comfortable with AI-assisted development workflows: using AI coding tools, crafting Golden Queries, and building or configuring skills for data agents;
• Must be comfortable with unstructured, fast-moving, and constantly evolving high-growth environments;
• Strong execution and ownership — able to drive technical work end-to-end from ambiguous problem to reliable solution;
• Ability to communicate complex technical concepts clearly and concisely to non-technical stakeholders;
• Advanced English written and verbal communication skills.
