Hey there future data wizard! Tired of corporate buzzwords and AI thats more PowerPoint than Python? Do you believe the best tool for the job isn’t always the most hyped one? Are you someone who loves to dig deep, understand how things really work and build solutions from the ground up? If you just screamed YES, then we might have the perfect playground for you.

At smartclip we’re not about chasing trends; we’re about solving real complex problems with data. We’re looking for a curious and pragmatic Data Scientist to join our passionate team. Forget maintaining legacy code — you’ll be diving headfirst into fresh challenges, turning trillions of data points into meaningful impact. You’ll enjoy the freedom to tackle problems your way at your pace with a smart and supportive team at your side. We’ll tell you what to solve; the how is up to you. You’ll never be alone though: we collaborate, not micromanage.

Your Mission

Is your idea of fun wrangling messy data, debugging ML pipelines and running experiments that actually tell you something? Do you know that correlation, causation and that pandas aren’t just cute animals? If your heart beats faster for code, queries and questions, keep reading. We’re on the hunt for a Junior Data Scientist who’s less into dashboards for the sake of dashboards and more into uncovering what really matters behind the metrics.

• Explore terabytes of real-world data, not toy datasets
• Work on questions that dont have answers on StackOverflow (yet)
• Build and improve data products and ML models with a team of domain experts
• Have the freedom to use the right tool for the right job, not just the fashionable one

Your Toolbelt

• 3 years of hands-on experience in Data Science
• Youre comfortable working with large-scale messy datasets even the kind that dont fit into memory
• For you state-of-the-art methods are not just the methods everybody use. You are not afraid to search for answers in scientific literature.
• Strong mathematical intuition; you dont just apply models, you want to understand why they work
• You follow best practices by default and know when its time to question them

Your Tools

• Python, comfy with pandas, scikit-learn & friends
• Data Science basics from feature engineering to model validation
• SQL joins, aggregations, subqueries
• Docker & Linux, smooth setup and deployment
• AI / ML real models, not just slide decks
• Git, because version control is second nature

Bonus Skills (nice to have) : Apache Spark / Kubernetes / Prefect / Airflow or similar / Torch / VLLM or LLM-related tooling / or similar / Shell scripting

Our Tech Stack

We build with the tools we love (and we love good tools): TypeScript, React, Python, SQL, Scala, Java, Docker, Kubernetes, AWS, GCP, C, GitHub and the occasional caffeine-fueled whiteboard sketch. We’re not afraid to throw something out if there’s a better way. Check out our open source stuff: in Your Loot Box
