Senior Data Scientist

As our Senior Data Scientist, you'll be responsible for: 

• Collaborating with your cross-functional peers from Revenue Management, Product, Design, and Engineering on an outcome-based team to craft and deliver on OKRs related to dynamic pricing recommendations and analysis for the short term rental industry. 
• Designing to ensure solutions are deeply informed by user needs, measurable outcomes, and aligned with Beyond’s product vision.
• Working closely with data engineers to design, build, test, and maintain data pipelines, ensuring production readiness, and deploying scalable solutions.
• Driving the application of modern AI technologies, such as RAG, MCP, and embedding-based semantic search to accelerate internal tooling and improve user-facing intelligence.
• Integrating observability, monitoring, and human feedback collection into ML pipelines and agentic systems to continuously improve model performance and user alignment.
• Applying tools like LangChain and other orchestration frameworks to prototype and ship LLM-powered assistants, agents, and automations that enhance customer decision-making.
• Mentoring fellow Data Scientists and championing best practices in experimentation, validation (e.g. A/B testing, synthetic controls), and interpretability.

So what kind of person are we looking for in this role? The person who will be successful in this role will be: 

• Curious - You are driven to understand how things work or why they don't. You are interested in finding out how your work impacts our customers and the world they live in.
• Collaborative - You enjoy exploring and committing as a team, you welcome others' ideas, and you value teamwork and team decision-making over being right and having things going your way.
• Result-oriented - You manage the trade-offs between speed and quality and are able to find the right balance. You would rather ship, measure, learn and iterate, rather than code the perfect component on the first try.
• Resilient - You can adapt and roll up your sleeves to help others. You operate at a stable pace with visibility most of the time and you are ready to embrace change when it happens.
• Proactive - You take initiative to identify opportunities and drive projects forward with minimal direction, independently navigating ambiguity to deliver impactful results.

Now that we’ve told you what the job looks like, here are the qualifications we're looking for in a candidate: 

• 5+ years of experience as a Data Scientist and 10+ years in SaaS overall, preferably in high-scale, multi-tenant platforms.
• Proven expertise in machine learning and statistical modeling, with a track record of delivering models that meaningfully move product or revenue metrics.
• Fluency with Python and tools such as pandas, numpy, scikit-learn, statsmodels, scipy, Spark, SQL, Streamlit, or other common data science frameworks.
• A strong product orientation, seeking to understand customer behavior, measure impact, and co-create value with cross-functional partners.
• An experimental mindset, with familiarity in designing and interpreting causal inference frameworks (e.g., A/B tests, synthetic controls).
• Hands-on experience with modern AI techniques and tooling, including vector search, embeddings, RAG pipelines, LangChain, and model observability platforms is a plus.
• Located in Brazil or Peru
• Experience in revenue management, dynamic pricing, or the short term rental industry is a strong plus.
