- 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

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

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

🌈 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 💖
