Ready to be a Titan?
The Data & Reporting Platform team powers ServiceTitan’s growth by delivering high-quality, low-latency, and reliable data and BI products that enable trust, acceleration, and data-driven decision-making for our customers and across ServiceTitan.
We are looking for a Principal Software Engineer to own the semantic model architecture at the heart of our data platform. The semantic layer is the single source of truth for business metrics and logic, and it powers critical data products such as Reporting, and Agentic Analytics. This role sits at the intersection of data modeling, platform engineering, and product thinking — you’ll define how data is modeled, governed, and consumed at scale across multiple product surfaces.
This is a T-shaped role: deep expertise in semantic modeling and data architecture, with the breadth to operate across the full data platform stack at the principal level. You’ll partner closely with our Data Foundations team (which owns ingestion and storage), our Reporting team (which owns the reporting experience), and teams building agentic AI capabilities; ensuring the semantic layer is the performant, scalable, and extensible foundation they all depend on.
Semantic Model Architecture: Design and evolve the semantic modeling layer that serves as the single source of truth for metrics, dimensions, entities, and business logic across all data products. Define the standards for how semantic models are authored, versioned, tested, and governed. Evaluate and drive the semantic layer technology strategy (e.g., dbt MetricFlow or equivalent).
Data Product Enablement: Architect how the semantic layer is consumed across distinct product surfaces such as Reporting (high-performance BI platform for customers), and Agentic Analytics (metadata-rich, discoverable interfaces that enable AI agents to reason over and query the semantic layer). Partner with adjacent teams to ensure the semantic layer meets each product’s unique requirements.
Performance & Scale: Own query performance, materialization strategies, pre-aggregation patterns, and cost optimization. Ensure the semantic layer is highly performant and scalable as data volumes and consumer demand grow.
Platform & Governance: Build the semantic layer as a true platform experience: self-service metric onboarding, developer-friendly abstractions, clear documentation, data validation, and governance guardrails. Make it easy for other teams to extend the semantic layer without compromising consistency or quality.
Technical Leadership: Operate as a technical leader across the Data & Reporting Platform organization. Participate in and drive design sessions across teams. Mentor engineers, manage stakeholder and leadership alignment. Contribute to architecture decisions that span from data foundations through reporting and analytics. Champion high-quality code with corresponding test coverage.
AI-Augmented Engineering: Use AI coding tools (Claude, Cursor, Copilot) as a core part of your daily workflow. Drive adoption patterns, build team-specific contexts and workflows, and set the standard for how the team multiplies velocity through AI-assisted development.
To effectively support our international teams, this position requires flexibility to overlap with US working hours as needed.
