A key business solution of Publicis Groupe, Publicis Media’s digital-first, data-driven global solutions deliver client value and drive growth in a platform-powered world. It is present in over 100 countries with over 23,000 employees worldwide. Overview About Performics & OneSuite Performics is the Performance Centre of Excellence within Publicis Groupe, delivering technology, data, and AI-driven marketing solutions for global brands. OneSuite is our unified marketing intelligence and automation platform powering agentic workflows, data processing, analytics services, and channel automation across Search, Social, Programmatic, Commerce, and Measurement. Data engineering is foundational across OneSuite — providing the data pipelines that power campaign activation across Search, Social, Commerce, Programmatic, and Measurement. About the Role We are seeking a Senior Data Engineer to lead the design, development, and evolution of data pipelines across OneSuite. This is a hands-on engineering role — you will write production-grade code, solve complex data engineering problems, shape pipeline patterns, and guide other engineers through technical influence. Responsibilities Core Responsibilities Data Engineering & Pipeline Development • Design and maintain data pipelines using PySpark and Databricks, following the medallion architecture (Bronze/Silver/Gold) for structured data transformation and quality. • Build and optimize ETL/ELT workflows that ingest, transform, and serve marketing performance data at scale. • Collaborate with analytics and data science teams to ensure clean, well-modeled, and accessible data assets across the lakehouse. • Implement data quality checks, schema enforcement, and lineage tracking across pipeline stages. Hands-On Development • Write high-quality, maintainable, production-ready code. • Integrate with external APIs (marketing platforms, cloud services, internal microservices). • Build and maintain CI/CD pipelines and infrastructure-as-code environments. • Lead code reviews, mentor engineers, and ensure high engineering standards. Performance, Reliability & Observability • Implement tracing, structured logging, metrics, dashboards, and alerting. • Optimize services for latency, concurrency, throughput, and cost efficiency. • Ensure system reliability through automated testing, load testing, error budgets, and resiliency strategies. • Partner with SRE to define SLIs/SLOs and improve platform-wide reliability. Cross-Functional Collaboration • Work closely with product, data, and SRE teams on shared designs across campaign activation domains. • Align architecture decisions across teams to ensure consistency and maintainability. Qualifications Must Haves Proficiency with SQL and NoSQL databases (PostgreSQL, DynamoDB, Redis, MongoDB) and familiarity with lakehouse platforms. Experience with or strong willingness to work in PySpark and Databricks, including the medallion architecture (Bronze/Silver/Gold). Hands-on experience with Docker, Kubernetes, CloudFormation, and cloud platforms (AWS or GCP). Strong CI/CD experience using GitHub Actions, Argo, or similar tools. Deep knowledge of observability practices — logs, metrics, traces, performance analysis. Proven ability to write clean, testable, well-structured production code. Nice to Have Experience with streaming or queuing systems (Kafka, Pub/Sub, SQS). Familiarity with AI/LLM systems and agentic workflow integration. Experience with Delta Lake, Unity Catalog, or other lakehouse governance and optimization tools. Core Competencies Technical Expertise: You own data pipeline design, solving complex data engineering problems while defining reusable patterns that improve scalability, reliability, and developer velocity. Leadership: You lead through influence — mentoring engineers, guiding architectural decisions, establishing engineering standards, and elevating craftsmanship without direct people management. Product Impact: Your systems directly shape OneSuite's performance, availability, and functionality across campaign activation for Search, Social, Commerce, Programmatic, and Measurement. Innovation & Learning: You stay current with emerging architecture patterns, cloud-native technologies, and data platforms. You introduce pragmatic innovations that deliver measurable engineering and product value. Collaboration: You work across teams — aligning direction and ensuring platform cohesion across campaign activation domains. You communicate clearly, build consensus, and drive clarity in complex system discussions. Additional information Publicis Groupe has fantastic benefits on offer to all of our employees.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
