Senior Data Engineer - Integrations (m/f/d)

At Adsquare, our mission is driven by our core focus:

• Passion – Solving complex challenges with great people, tech, and data.

• Niche – Location Intelligence for Programmatic Advertisers.

Our core values are integral to everything we do:

• Drive: We turn ambition into action to deliver valuable outcomes.

• Resilience: We adapt, persevere, and grow stronger.

• No BS: We value honesty, transparency, and clear communication.

• Humble: We choose modesty over vanity and let results speak for themselves.

• Moral Compass: We do the right thing with fairness, integrity, and respect.

We seek candidates who not only bring top-tier technical expertise but also embody these values in every aspect of their work.

You will join the Integrations Squad, a high-performance team responsible for the "final mile" of our data product. This team ensures our massive datasets reach external partners reliably and securely.

• Structure: You will join a team of 4 Backend Engineers, a Senior Data Engineer (DE) and a Technical Product Owner. Together with the other DE will be the Subject Matter Experts (SMEs) for Data Engineering within this squad.

• Culture: You will work under the guidance of a Technical Team Lead and the broader Data Engineering Guild at Adsquare but will operate with a high degree of autonomy. Because you are sitting alongside Backend Engineers, we value a software engineering mindset applied to data problems.

We are looking for a Senior Engineer to architect privacy-first, massive-scale data egress solutions.

• Architect Scalable Egress: Design and build the big data architectures required to transfer terabytes of data to third-party partners. You will optimize for throughput, latency, and cost.

• Engineering Rigor: Elevate the data engineering standards within the squad. Implement CI/CD workflows, infrastructure-as-code (Terraform), and automated testing.

• Data Pipeline Ownership: Take full ownership of the pipeline lifecycle—from raw data ingestion to transformation and external delivery—using Python, Spark, and AWS native tools.

• Collaboration: Bridge the gap between Data and Backend. You will align with other Data Experts at Adsquare on best practices (e.g., file formats like Parquet/Iceberg) and introduce these standards to your squad.

• Mentorship: Act as a technical leader. While you don't manage people, you are expected to mentor junior members and conduct code reviews that raise the bar for quality.

We are looking for a candidate with 4+ years of experience in Data Engineering or Backend Development with a heavy data focus. You must be comfortable working in a self-organized, agile environment.

Must-Have Technical Skills:

• Big Data Mastery: Deep experience with large-scale processing frameworks (e.g., Apache Spark, AWS Glue, EMR). You understand how to handle TB-scale datasets efficiently.

• Database & Storage Architecture: You don't just query data; you choose the right home for it. You have deep expertise in the trade-offs between OLAP and OLTP systems and have built solutions using NoSQL document stores, key-value stores, and horizontally scalable data warehouses (e.g., Redshift, Snowflake, StarRocks or Lakehouse architectures) as core building blocks.

• AWS Native: You have architected solutions using the AWS ecosystem (S3, Athena, Batch, Glue, Lambda).

• Infrastructure as Code: Production experience with Terraform is mandatory. You treat infrastructure as software.

• Language Proficiency:

  • Python: Advanced proficiency. You write modular, production-ready code, employing appropriately both functional programming and objected oriented programming approaches. You use test-driven development.

  • SQL: Excellent command of SQL for transformation and analysis.

• Pipeline Orchestration: Experience with tools like Airflow and dbt to manage complex dependency graphs.

• Engineering Fundamentals: Solid grasp of computer science principles, data structures, algorithms, and git-flow/CI/CD pipelines / gitlab / github.

Nice-to-Have Skills:

• Polyglot Programming: Experience with a second compiled or strongly typed language is highly valued (e.g., Scala, Go, Kotlin, C++ or Java).

• Data Formats: Expertise in optimizing file formats (Parquet, Avro, Iceberg) for performance.

• Backend Context: Experience working closely with Backend engineers or familiarity with Backend architectural patterns (microservices, API design).

On top of a competitive package…

• We are open to flexible work models: we work on a hybrid mode and remotely from anywhere in the world up to 3 months per year
• To encourage education and professional growth, we offer an individual yearly budget of 1.200€
• You are entitled to 30 vacation days per year
• We offer Urban Sports Club membership, company pension scheme
• Regular team events and company events organised by our People team (Trust us, they know how to throw a party!)
• We equip you with the latest hardware and provide you with all the tools you need to thrive
