About Wolt

At Wolt, we create technology that brings joy, simplicity and earnings to the neighborhoods of the world. In 2014 we started with delivery of restaurant food. Now we’re building the delivery of (almost) everything and you’ll find us in over 500 cities in 30 countries around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe.

Working at Wolt isn’t always easy, but it’s definitely exciting. Here you’ll learn more, build more, and ship more than in most other companies. You’ll be challenged a lot, but also have a lot of fun on the way. So, if you’re a self-starter with drive and entrepreneurial spirit, this could be the ride of your life.

Wolt’s AdTech & Promotions team is building the systems that power how restaurants and brands grow on our platform. From campaign creation to optimization and forecasting, we develop tools that help advertisers make smarter decisions and drive measurable results. As we expand our offering, we are investing in new capabilities that combine real-time data, scalable systems, and intuitive user experiences to unlock the next phase of growth.

We’re looking for a Staff Engineer to join the Wolt AdTech & Promotions organization, who can drive technical direction across this space and help us build reliable, scalable systems that directly impact revenue and advertiser success.

What you’ll be doing

Drive the technical vision and architecture for Wolt’s AdTech and Promotions platforms, ensuring they are scalable, reliable, and high-performing.
Provide technical leadership across multiple teams and projects, bringing architectural consistency to complex, large-scale systems.
Work across the end-to-end domain, contributing to backend services, data pipelines, and advertiser-facing tools.
Design and evolve systems that support campaign execution, targeting, ranking, allocation, and reporting in real-time or near real-time environments.
Partner with engineering, product, and data stakeholders to align priorities, improve campaign performance, and manage trade-offs in a revenue-driven environment.
Lead large cross-team projects, guiding them from concept to rollout across multiple regions and time zones.
Ensure strong operational excellence, including observability, reliability, and incident readiness for revenue-critical systems.
Promote best engineering practices, mentor engineers across teams, and support their growth in scalability and system design.
Act as a bridge between technical and non-technical colleagues, ensuring clarity and alignment across functions.
Contribute to the technical roadmaps of AdTech and Promotions platforms by collaborating with other senior engineers.
