Own pricing science end to end, from elasticity and demand modeling to shipping and monitoring models on GCP, with clear guardrails and operator-friendly explainability."About WalkwayWalkway 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 RoleWe'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.
This is a hands-on, high-impact role with the opportunity to lead projects and people.We're a US-based company; this position is a remote contractor role with strong overlap to EU/US time zones.What you'll doPricing Science & ModelingDesign 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.MLOps & Data EngineeringOwn feature pipelines and model services on GCP: BigQuery, Cloud Run, Pub/Sub, Cloud Storage, Vertex AI (or MLFlow), dbt/Mage/Airflow.Build reliable ELT/ETL (schema design, data contracts, idempotency, SLAs), feature stores, and model registries.Ship models to production with CI/CD, canary/A-B rollouts, monitoring for drift/quality, and automated re-training schedules.You treat models as products, you design APIs and batch jobs that other services depend on.Implement privacy and security best practices (PII handling, access control, auditability).
Leadership & CollaborationCo-lead the pricing roadmap; break down research into shippable increments.Mentor data scientists/engineers; set standards for code, reviews, docs, and experiment hygiene.Work cross-functionally with Backend, Integrations, and Design; communicate clearly with non-technical stakeholders.What you've shipped / Requirements7+ years in Data Science/ML with dynamic pricing / revenue management in adjacent spaces (travel, hospitality, mobility, e-commerce, marketplaces, ads, or gig platforms).
Strong Python (pandas, numpy, scikit-learn; PyTorch/TensorFlow a plus) and SQL; comfort profiling & optimizing code/queries.Proven data engineering chops: building production pipelines/orchestration (dbt, Airflow/Mage), data modeling, testing, monitoring, and cost/perf tuning.Depth in time-series forecasting, elasticity/choice models, causal inference or uplift, and experiment design.Experience deploying models/services on GCP (or AWS/Azure and willing to pivot): BigQuery, Cloud Run, Pub/Sub, Vertex AI/MLFlow, Cloud Functions/Scheduler.
Evidence of taking a model from notebook to production service with clear SLOs, versioned rollouts, and post-incident learnings.Comfortable with MLOps: model registry, CI/CD for ML, drift/quality monitoring, feature stores, reproducibility.Excellent communication; can turn ambiguity into a plan and explain trade-offs to product & customers.Bonus: Prior project or team leadership (tech lead/manager or de-facto lead on large initiatives).
Nice to haveOTA / travel tech integrations, pricing under parity and channel constraints.Reinforcement learning / contextual bandits in production.DuckDB, Spark/Beam, Redis, KafkaExperience designing explainable pricing UIs and operator-facing levers (guardrails, sensitivity sliders, override workflows).
