Team Overview

The Performance Measurement team is a core part of the Enterprise Performance pod, responsible for building a holistic measurement framework that enables advertisers to accurately value their ad spend across different screens. Our mission is to move beyond basic metrics to provide deep insights into advertiser outcomes like incrementality and cross-screen attribution.

The team:

• Builds and maintains a holistic measurement framework encompassing pixels, attribution, Multi-Touch Attribution (MTA), and Incrementality.
• Improves data quality by facilitating pixel management and increasing landing rates to ensure high-quality attribution.
• Integrates 3rd-party solutions to offer advertisers trusted external validation of campaign performance.
• Develops advanced solutions for incrementality across both CTV and web environments to prove the true value of ad spend.

As a Software Engineer in the Measurement & Attribution team, you will contribute to the development of our core performance measurement infrastructure. You will work on unifying delivery insights across web and CTV, helping to bridge the gap between different advertising environments. Your work will directly impact how our clients optimize for real business outcomes rather than just media KPIs.

As a Senior Software Engineer, your missions will be to:

• Design and ship features across complex backend systems, primarily using Scala, Golang and Python to support high-scale measurement and attribution.
• Develop and integrate cross-screen attribution workflows to provide a unified view of performance.
• Collaborate with the Data team to build and deploy incrementality solutions for diverse channels including web and CTV.
• Optimize and scale pixel management systems to reduce technical friction in campaign setup and improve observed performance.
• Contribute to full-stack development using Node.js and React where necessary to surface insights and measurement controls to our users in TAM.
• Ownership over the performance attribution data pipeline, conversion measurement API and Event Manager UI on TAM

What will you bring to the team?

• 7+ years of professional software development experience, with a significant focus on backend systems, infrastructure, or platform engineering.
• Deep proficiency in at least one of Java, Go or Scala with a solid understanding of object-oriented design, functional programming paradigms, and distributed system architectures.
• Good programming abilities. Testing your code is second nature to you. You are mindful of your application’s architecture, performance, maintainability, and overall quality.
• Familiarity with large, high-throughput, distributed systems, and connecting together and processing large amounts of data
• Analytical and experimental mindset in any feature or project you’ll ship to production. You like to prove an idea first before you invest large amounts of effort into development.
• Good communication skills and ability to work collaboratively within a diverse global team. You are an active listener and a dialogue facilitator, you know how to explain your decision and like sharing your knowledge.
• Multiple shipped projects in Software Engineering.
• Production knowledge and practices (Release, Observability, Troubleshooting…), thanks to multiple shipped projects / applications. Strong problem-solving skills.

Our main Stack

• Front: React, TypeScript, Angular
• Back: Scala, Go, Python
• Database: MySQL, PostgreSQL, BigQuery, Athena, Cassandra, Redis & Memcached
• Infrastructure: AWS, GCP, Inhouse Kubernetes
