Walkway builds AI-driven revenue intelligence for the tours & activities industry. We help operators grow through dynamic pricing, competitive benchmarks, and data-rich insights. Our stack is GCP-centric and data heavy (real-time + batch).

The Role

We’re hiring a Senior Data Scientist specialized in Pricing who is also excellent at data engineering . You’ll co-own the pricing science roadmap end-to-end from demand / elasticity modeling to production deployment and monitoring - and help shape product and platform decisions with the founders.

We’re a US-based company; this position is a remote contractor role with strong overlap to EU / US time zones.

What you’ll do

Pricing Science & Modeling

• Design the pricing methodology for multiple channels (direct + OTAs) : demand forecasting, price elasticity estimation, competitor response, inventory / lead-time effects, seasonality & events.
• Build hybrid rules + ML systems that start simple (guardrails, explainability) and graduate to Bayesian / causal, RL / bandit approaches where appropriate.
• Define KPIs (revenue / seat, conversion, occupancy, margin) and attribution logic; build offline / online evaluation, backtests, and simulation / sandbox environments.
• Partner closely with Product to keep price recommendations explainable and operator-friendly.
