At Roofr, we’re obsessed with our customers. That’s what makes Roofr’s CRM special. We started by building essential sales tools like aerial roof measurements and digital sales proposals. But when our customers asked for a simple, affordable way to manage and scale their entire businesses, we listened. So, we created a CRM that connects these solutions—along with payments, material ordering, and more—into a seamless, powerful platform. It’s an exciting time to be part of an extraordinary startup that is already successful, yet still early enough to offer its team significant growth, equity, and the opportunity to make a real impact.

As a Staff Data Scientist at an early-stage, high-growth company, you'll play a critical role in turning raw data into insights and apps that shape strategy, fuel growth, and improve the customer experience. You'll be partnering directly with senior leaders and an experienced data & analytics team to drive data science and experimentation initiatives across sales, marketing, and product areas — putting both traditional analysis and ML to effect change.

Architect optimization analyses and forecasts that help leaders pinpoint opportunities across Growth, Strategy, Revenue, Marketing, and Product teams.

Design counterfactual analyses and A/B tests to enable data-driven evolution of our UX, product features and customer experience.

Build data apps that automate and supercharge our sales and marketing processes.

Own your projects end-to-end — from framing the business question to shipping the model to presenting the recommendation, with the autonomy to decide how you get there.

Work on top the same semantic layer and DBT models powering our AI-driven analytics stack (Snowflake Cortex, Sigma, Claude, etc.), so your analyses build on a single-source-of-truth data.

Create data science frameworks — templates and guides that data practitioners across the org can leverage and build upon.

7+ years of experience in data science in a fast-moving business setting,



with a track record of running the show on ambiguous, high-stakes problems.

Hands-on experience with a modern cloud data stack — Snowflake, DBT, and various BI tools (Sigma, Looker, Metabase, Omni, or similar).

Strong SQL and statistical modeling skills, with a track record of building forecasting and causal inference models.

You appreciate scalable data models — you contribute to the shared semantic layer, and let the whole org benefit.

You're just as excited to hack together a scrappy new analysis or app as you are to build scalable products that meet stringent quality standards.

Self-driven and organized, with the ability to manage projects across cross-functional stakeholder groups with minimal oversight, keeping everyone updated on progress and next steps.

An amazing communicator and presenter, equally comfortable in a room with executive leadership or heads-down in the data.

A true team player — you love brainstorming, peer reviews, and pressure-testing ideas.

At Roofr, we’re big fans of AI. It helps us write job descriptions that don’t put you to sleep, takes notes during interviews so we can actually listen, and even helps us track down awesome humans like you.

Feel free to use AI to prep, research, or get pumped up for your interview (we see you, ChatGPT power users ). But when it’s time to chat, we’d love to meet you, not your AI alter ego. We are committed to equal employment opportunity in the workplace regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or veteran status.
