## Job description

**About the Role**

We’re looking for a **Staff Data Scientist** to shape the future of our marketplace through advanced analytics, experimentation, and machine learning. You’ll **define the technical direction** of data science initiatives, **influence product strategy**, and **mentor other data scientists** to elevate our analytical standards and impact.

As a Senior Technical Leader, you’ll partner closely with Product, Engineering, and Operations teams to **turn data into decisions** that improve reliability, growth, and user experience across markets.

**What You’ll Do**

**- Lead** data science initiatives with company-wide impact — from experimentation frameworks to ML systems and causal inference methods

**- Define best practices and standards** for experimentation, modelling, and analytical excellence across teams

**- Partner with Product and Engineering leadership** to identify and prioritise high-leverage opportunities

**- Develop and deploy** scalable models and data products that drive measurable business outcomes

**- Mentor and coach** other data scientists and analysts, helping them deliver higher-impact work

**- Communicate insights and recommendations** to senior leadership, influencing product and growth strategy

**- Contribute to Heetch’s data platform evolution**, ensuring data quality, reliability, and efficiency at scale

**You’ll Thrive In This Role If You**

- Have a **deep understanding of statistics, experimentation, and causal inference**, and know how to apply them pragmatically

- Are fluent in **Python, SQL**, and modern data/ML tooling

- Have **experience bringing ML models into production** and measuring their long-term business impact

- Are skilled at **translating complex technical findings into actionable business insights**

- Are a **collaborative leader** who mentors peers and sets high standards for analytical rigor and impact

- Have **7+ years** of experience in data science, ideally with 2–3 years in a Staff-level or tech-lead capacity

**Nice to Have**

- Experience in marketplace or pricing systems (supply–demand modelling, matching, or fraud detection)

- Experience leading data science guilds, chapters, or communities of practice

- Familiarity with MLOps, feature stores, or causal inference frameworks

🌈 **Ride with Pride at Heetch** 🌍

We’re all about building a diverse, inclusive team where everyone feels safe, seen and celebrated. Different backgrounds, perspectives, and vibes? Bring it on. That’s how we grow.

And hey — studies show some people (especially women and early-career folks) hold back from applying unless they tick every single box. Don’t do that. If this role sparks something in you, but you’re not sure you match everything — apply anyway. We care about potential, mindset, and energy just as much as experience.

**Everyone’s welcome on the Ride 💖**
