Principal Software Engineer

Responsibilities

• Solve real business needs at large scale by applying software engineering and analytical problem-solving skills.
• Design, develop, and support the semantic modeling layer that translates semantic queries into correct, high-performance SQL.
• Create architecture and design, influence the semantic layer roadmap, and take ownership over new capabilities spanning metrics, dimensions, relationships, and governance.
• Ensure semantic queries produce correct results while meeting the performance and scale demands of interactive analytics over petabyte-scale data.
• Partner with the Cortex and AI teams to make the semantic layer the reliable grounding source for natural-language and agent-driven analytics.
• Understand the trade-offs between expressiveness, correctness, performance, and cost, and build solutions that hold up as usage grows.
• Mentor and grow engineers, and raise the technical bar across the team.
• Ensure operational readiness of the features we ship and meet commitments to customers on correctness, availability, and performance.

Requirements

• 15+ years of industry experience designing, building, and supporting large-scale data or systems software.
• Strong computer science fundamentals including data structures, algorithms, and complexity analysis.
• Deep experience with at least one of: query compilation and optimization, database or query engine internals, semantic/metrics layers, or BI and analytics infrastructure.
• Strong grasp of SQL semantics and relational modeling.
• Fluency in Java or another similar object-oriented language is preferred.
• Track record of identifying and implementing creative solutions to complex, ambiguous problems.
• Ability to work effectively across engineering teams in multiple locations.
• BS in Computer Science; Masters or PhD preferred.
