Data Scientist

About Tofu

How do you distinguish between real and fake in an AI world?

This question has crippled the recruiting industry overnight. Tofu is building one of the most important companies of our time and the layer to fix it.

AI has made it easier than ever to fake credentials, impersonate real people, and apply to jobs at scale using synthetic identities. More than 60% of remote applicants are fake, there were 75M detected deepfakes last year, and the number of state-sponsored groups hired by Fortune 500s grew 220%.

The hiring funnel has become the front door to the enterprise, and AI has cracked it wide open. It’s a $96 billion problem that needs to be solved.

We’re changing that.

Tofu is building a new standard for security in hiring.

And we just raised $5M from Slow Ventures and Founder Collective to step on the gas.

If you want to help build the trust layer for the internet and redefine how identity works in the AI era, we’d love to talk.

About the Role

We’re hiring a Data Scientist to work directly with our leadership and engineering teams to uncover the signals in the noise.

This is a high-leverage, high-trust role. In an environment where synthetic identities are evolving daily, you will be our lead detective. You won't just be "analyzing data" - you will be discovering the patterns that allow us to stay ahead of state-sponsored fraud and deepfakes.

You’ll shape the roadmap by deciding which signals matter, work to inject intelligence into our product, and make strategic decisions to help Tofu reach $10M in ARR by ensuring our core product is bulletproof.

In this role, you will:

• Master our Data: Get deeply familiar with our data: where it comes from, how it’s generated, and why it exists.

• Hunt for Signals: Explore raw, imperfect datasets to find patterns, anomalies, and fraud signals that others miss.

• Guide Strategy: Build analyses that help us understand trends and decide what signals or models to build next.

• Build Tools: Write SQL and Python to investigate data, validate assumptions, and build small internal tools or scripts so we always know what our data looks like.

• Drive Transparency: Help design and build analytics dashboards that give our customers visibility into the trust layer.

• Ensure Quality: Be heavily involved in QA before new models or signal iterations go out, working closely with engineering to request better instrumentation and logging.

Who You Are

• Technical Proficiency: Highly skilled in SQL and Python.

• Query Expert: Comfortable with Elasticsearch, KQL, and DSL query languages.

• Data Intuition: You thrive on messy, incomplete, real-world data and enjoy building tools from scratch to tame it.

• Curious & Skeptical: You are detail-oriented and care deeply about correctness and data quality; you aren't afraid to ask "why" and push for better data.

• Autonomous: You thrive in ambiguity and are comfortable working without perfect specs or pre-defined roadmaps.

• Collaborative: Interested in working across product, engineering, and ML teams to turn data insights into production-ready security features.

Bonus (Nice to Have):

• Django experience

• Experience in fraud, trust & safety, or risk systems

• Experience building customer-facing analytics

• Familiarity with ML workflows or model evaluation

Why Tofu and this Role

• You’ll help build the trust layer for the internet, one of the defining problems of the AI era.

• Work directly with a team obsessed with building a generational company.

• Insane level of ownership - your analyses will directly dictate the product roadmap.

Benefits & Perks

• Competitive salary + meaningful equity.

• Comprehensive health benefits.

• 3 weeks of vacation.

• New laptop and gear to do your best work.

• Tofu swag your friends will want to steal.
