About the role

As a Backend Engineer, you will drive the development of the core systems powering Ads — from building scalable services for ad serving, bidding, and pricing, to integrating sponsored content into our existing ranking and delivery infrastructure. You’ll design and implement high-performance APIs, real-time decision systems, and data pipelines that ensure ads are relevant, efficient, and seamlessly embedded into the user experience.

This is a foundational role: you’ll be one of the early engineers shaping the Ads & Monetization platform, working closely with Product, Data Science, and other Engineering teams to define architecture, establish best practices, and build systems that scale with the business.

Main tasks and responsibilities

• Architect, design, and operate scalable, low-latency services for ad serving, auctions, bidding, and pricing across Bolt Food
• Integrate sponsored listings, banners, and targeted promotions into Bolt’s existing ranking and delivery infrastructure
• Build real-time decision systems and data pipelines for targeting, relevance, budget pacing, and campaign reporting, ensuring accurate billing and spend tracking
• Design high-performance APIs for merchants, advertisers, and internal teams
• Set the technical direction for the Ads & Monetization domain and establish engineering standards as one of its founding engineers
• Partner with Product, Data Science, and Commerce to take ads features from idea to launch

About you

• You have solid backend engineering experience and a track record of designing and shipping scalable, reliable, high-throughput systems
• Experience with ads platforms, real-time bidding/auctions, marketplaces, search/ranking, or recommendation systems is a strong advantage
• You feel at home with microservice architecture and are experienced in API design, possess a solid understanding of algorithms and data structures, and care about latency and performance trade-offs
• Experience with event streaming, data pipelines, or experimentation/A-B testing is a plus
• You have empathy for stakeholders and end-users, and thrive in an environment with a fast feedback cycle
• Previous technical leadership or tech-lead experience is a plus

Why you’ll love it here

• Accelerate your professional growth with unique career opportunities. Be the one of founding engineers of a new and complex product
• Enjoy a rewarding salary and stock options, knowing that as we  succeed, so do you.
• Take care of your physical and mental health with our wellness perks.
• Celebrate 5 years  with a 1-month paid sabbatical to recharge.
• Connect with colleagues at annual company events and smaller team gatherings.
• Balance flexibility and in-person collaboration with our hybrid model, including at least 12 monthly in-office days.
