Senior Data Scientist
About Longtail Technologies
Longtail is building an intelligent decision-streaming platform that helps airlines make smarter decisions in real time. By combining automation, proprietary algorithms, and live travel data, we enable airlines to optimize pricing, availability, and product flexibility across thousands of routes worldwide. We're a fast-growing team solving complex, real-world problems at global scale. If you enjoy uncovering insights from large datasets and building systems that influence real strategic decisions, you’ll feel at home here.
About the Role
We are looking for a Senior Data Scientist to lead the development of our elasticity intelligence capabilities. This is a high-impact, greenfield role within our new Synergy Products squad, with a strong focus on data discovery — exploring newly acquired travel datasets to uncover patterns that shape how we understand demand elasticity. You will work at the intersection of data discovery, statistical modeling, and product strategy, identifying where elasticity insights can drive the most value for airlines.
This is an individual contributor role with significant ownership and autonomy from day one, working closely with product and engineering teams to turn analytical discoveries into product impact.
What You’ll Build
You will design and deliver:
- Exploratory analytical frameworks that uncover elasticity patterns across travel datasets
- End-to-end elasticity models grounded in strong statistical methodology
- Robust evaluation frameworks to validate model assumptions
- Production-ready model architectures with data engineering
- Clear analytical insights that inform product and pricing strategy
What Success Looks Like
Within your first three months, you will have delivered:
- A clear exploratory analysis of key travel datasets identifying the most promising areas for elasticity modeling
- A defensible view of elasticity across priority datasets
- A validated modeling framework with documented assumptions and robustness checks
- A proposal for production deployment of elasticity models
- Alignment with the product roadmap
- Strong cross-functional collaboration with product, engineering, and data teams
What You’ll Do
Your work will span both data discovery and model development, including:
- Exploring large-scale travel datasets to identify patterns and opportunities related to demand elasticity
- Designing and building elasticity models end-to-end
- Evaluating model robustness and statistical validity
- Translating findings into clear product and pricing insights
- Collaborating with data engineering to productionize models and pipelines
- Communicating statistical insights clearly to product and leadership stakeholders
Our Tech Stack
You don’t need to know everything on day one — we value strong fundamentals and the ability to learn quickly.
Our ecosystem includes:
- Databricks (core platform)
- AWS
- Large-scale data lake architecture
- High-volume travel datasets
What We’re Looking For
We’re looking for someone who:
- Has experience building elasticity or demand models in production
- Brings strong applied statistics and experimentation skillsIs comfortable working with large, complex datasets
- Can evaluate and communicate model quality clearly
- Owns projects end-to-end with high autonomy
- Works collaboratively with a low-ego mindset
About You
You’ll likely thrive in this role if you have:
- Experience with pricing, retail, marketplace, e-commerce, or travel data problems
- A track record of ramping quickly in new domains
- A systems mindset beyond individual models
- Strong curiosity and the ability to discover insights in complex datasets
Nice to Have
- Experience working with travel or airline datasets
- Experience proposing production architectures for data science systems
Why You’ll Love Working at Longtail
At Longtail, you’ll build technology used by real airline partners at global scale.
You'll:
- Work on high-impact analytical problems
- Collaborate with experienced engineers and product leaders
- Take real ownership of complex systems
- Turn data discovery into product impact
We’re a distributed, collaborative team that values clarity, transparency, and sustainable ways of working.
