Role
Who you are
- Strong ownership mindset and ability to work autonomously from problem research to production deployment
- 5+ years of experience working in ads, ranking, recommendation systems or marketplace optimization domains
- Strong experience with learning-to-rank (LTR) models and recommendation systems
- Solid understanding of ads auction mechanics, bid optimization, and pricing strategies
- Proficiency in Python and SQL; experience with CatBoost, XGBoost, or similar gradient boosting frameworks is a plus
- Experience is great, but what we really look for is drive, intelligence, and integrity. So even if you don’t tick every box, please consider applying!
What the job involves
- We're looking for an experienced Data Scientist to join our Ads & Monetization team and help build intelligent ranking, pricing, and bidding systems for our advertising platform.
- If you're excited about applying machine learning to marketplace monetization challenges across Bolt's 200M+ users, you'll find plenty of impactful work here
- We are building an advertising and monetization platform, enabling merchants and brands to reach customers through sponsored listings, banners, and targeted promotions across Bolt Food.
- You'll drive the data science roadmap for Ads — from building automated pricing and bidding engines that maximize value for advertisers and users to integrating sponsored content into our existing ML ranking systems.
- This is a foundational role: you'll be the first dedicated Data Science hire for Ads & Monetization, working closely with Product, Engineering and Data Science teams
- Develop bidding and auction algos that enable fair price discovery and efficient budget allocation
- Build conversion prediction models (pCTR, pCVR) to power automated CPA/CPO pricing for self-serve merchant advertising
- Design and implement ranking models that blend sponsored listings with organic results, optimizing for user experience and advertiser ROI
- Partner with other data science teams to extend existing ranking infrastructure with ads-specific features and signals
- Design and run experiments to validate pricing approaches, measure incrementality, and estimate causal impact of ad placements
Our take
Across Europe, more and more people are choosing flexible, on-demand transport instead of owning a car. And ride-hailing, shared vehicles and new technology like autonomous driving are all part of this shift. So, cities are pushing for safer and more efficient transport, which is encouraging mobility companies to invest in electric vehicles and even driverless solutions which could eventually reshape urban travel.
Bolt has positioned themselves right in the center of this change, with is leading mobility platform that offers ride-hailing services across more than 50 countries. Through its app, Bolt connects users with transport options designed to be affordable and simple.
Recently, the company partnered with Stellantis to explore Level 4 autonomous, driverless vehicles, showing just how far ahead Bolt is looking for its next phase of mobility.
That said, Bolt operates in a very crowded market and urban mobility is highly competitive, with many local and international players all trying to come out on top. Even so, demand for shared and on-demand transport is at an all time high and only growing. Bolt's broad geographic reach, focus on scale and willingness to invest in future technologies puts it in the perfect position to keep growing.
