Realize your potential by joining the leading performance-driven advertising company!

As a Senior Software Engineer on the Dynamic Creative Optimization team in our Budapest office, you’ll play a vital role in building and optimizing the large-scale infrastructure that powers one of Taboola’s revenue-driving systems. You’ll design and develop highly scalable backend services that process hundreds of thousands of real-time requests per second while enabling intelligent decision-making for one of the world’s largest advertising marketplaces. You’ll own complex engineering challenges end-to-end and directly influence products that reach hundreds of millions of users every day.

To thrive in this role, you’ll need:

• 5+ years of backend software engineering experience developing production systems using Java or another object-oriented programming language (preferably Java 8+).
• Experience designing and building large-scale distributed systems and high-performance backend services.
• Strong experience with SQL and NoSQL databases in production environments.
• Solid understanding of web architectures, APIs, distributed systems, and scalable system design.
• Experience with Kafka, Docker, Kubernetes, Jenkins, or other large-scale data technologies.
• B.Sc. in Computer Science or an equivalent technical degree.

Bonus points if you have:

• Solid programming skills in Python
• Experience designing and operating telemetry, metrics collection, and alerting stacks at scale (Prometheus, Grafana, ELK/logging).
• Practical background in optimizing infrastructure costs and resource efficiency across cloud and on-prem.
• Knowledge of machine learning, algorithms, data mining, or real-time bidding systems.
• Experience with Spark or HDFS.

How you’ll make an impact:

• Design, build, and optimize backend infrastructure supporting one of Taboola’s largest real-time data platforms.
• Own features end-to-end, from architecture and implementation through deployment, monitoring, and continuous improvement.
• Develop highly scalable services processing hundreds of thousands of requests per second and tens of terabytes of new data daily.
• Collaborate closely with experienced software engineers to solve complex distributed systems challenges.
• Build innovative platforms that improve real-time decision-making, experimentation, and marketplace performance.
• Drive technical excellence while influencing products that impact billions of content recommendations across the open web.
