Join Us and Lead the Real Estate Revolution!

We are looking for a mid/senior-level data scientist who is equally comfortable writing SQL queries and ML models as they are stepping into a room with stakeholders to solve business problems. This person will be the go-to data consultant for internal teams — from product managers to the CEO — helping them make data-driven decisions, build experiments, and uncover strategic opportunities.

What You'll Be Doing:

• Collaborate with business stakeholders to deeply understand problems and design data-backed solutions.
• Perform ad hoc analysis, report, A/B test evaluation, and causal inference when needed.
• Develop, test, and deploy machine learning models in production (e.g., demand forecasting, pricing models, recommendations etc.).
• Generate data visualizations and dashboards to communicate insights clearly.
• Collaborate with cross-functional teams to define business problems and translate them into data solutions.
• Act as a data partner to stakeholders — translating complex questions into analytical plans, and results into actionable recommendations.
• Stay updated on latest tools, techniques, applications and best practices in data science and machine learning.

What We're Looking For:

• At least 3 years of experience in data science, analytics, or engineering roles.
• Strong SQL skill and using Python for software engineering, data wrangling and ML-modelling.
• Familiar with libraries such as Pandas, NumPy, Scikit-learn, TensorFlow or other similar ML/DL libraries.
• Strong understanding of statistical modeling, hypothesis testing.
• Experience deploying models to production (APIs, batch jobs, etc.).
• Excellent communication and stakeholder management skills — able to translate data insights into business impact.
• Experience with big data platforms (Spark, Hadoop), cloud services (AWS, GCP), and MLOps.
