<h2 id="EMGoffer-Whatwillyoudo?"><span style="font-size: 12pt;">What will you do?</span></h2>
<p><span style="font-size: 12pt;">As a <strong>Data Engineer</strong>, you'll be a key part of our data platform team, responsible for designing, building, and maintaining robust and scalable data pipelines. You'll work closely with data scientists, analysts, and server side engineers to ensure our data is reliable, accessible, and ready for analysis. Your expertise will be crucial in expanding our <strong>data warehouse</strong> and <strong>data lake</strong> capabilities, enabling us to deliver next-generation ad tech solutions.</span></p>
<p><span style="font-size: 12pt;"><strong>Your mission will be to:</strong></span></p>
<ul>
<li style="font-size: 12pt;"><span style="font-size: 12pt;"><strong>Develop and Optimize Data Pipelines:</strong> Design, build, and maintain ETL/ELT pipelines using <strong>Apache Spark</strong> to ingest, process, and transform large-scale datasets from various sources.</span></li>
<li style="font-size: 12pt;"><span style="font-size: 12pt;"><strong>Manage Cloud Infrastructure:</strong> Architect and manage our data infrastructure primarily on <strong>Google Cloud Platform (GCP)</strong> or <strong>Amazon Web Services (AWS)</strong>. This includes services like BigQuery, S3, GCS, EMR, and AirFlow.</span></li>
<li style="font-size: 12pt;"><span style="font-size: 12pt;"><strong>Enhance Data Storage:</strong> Improve and manage our <strong>data warehouse</strong> and <strong>data lake</strong> solutions, ensuring data quality, consistency, and accessibility for business intelligence and machine learning applications.</span></li>
<li style="font-size: 12pt;"><span style="font-size: 12pt;"><strong>Collaborate and Innovate:</strong> Partner with cross-functional teams to understand data needs and implement solutions that support new product features and business initiatives.</span></li>

</ul>
<h2 id="EMGoffer-Whatyoubringtotheteam"><span style="font-size: 12pt;">What will you bring to the team?</span></h2>
<ul>
<li class="p1">
<p><span style="font-size: 12pt;"><strong>5+ years of data engineering experience</strong>, building and operating production data pipelines at scale (TB+ datasets, hourly/daily batch or streaming workloads).</span></p>
</li>
<li class="p1" style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Hands-on production experience with Apache Spark</strong> (batch, streaming, or both). You should be able to walk through a non-trivial Spark job you wrote, explain partitioning and shuffle behavior, and describe how you tuned it. <strong>Language is not a filter:</strong> Scala, Python, or Java are all fine. What matters is that you can debug and ship production Spark code, not which language you write it in.</span></p>
</li>
<li class="p1" style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Production experience on GCP or AWS</strong> for at least one full project lifecycle (design, build, deploy, operate). Dataproc/EMR for compute, GCS/S3 for storage, BigQuery/Redshift/... for warehousing. <strong>GCP is preferred</strong> given our current stack, but strong AWS candidates are welcome and will ramp on GCP.</span></p>
</li>
<li class="p1" style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Production experience with Kafka</strong> or a Kafka-compatible streaming platform. Our pipelines rely on streaming, so this is a core requirement. You have debugged a real production incident involving consumer lag, rebalancing, or data loss.</span></p>
</li>
</ul>
<h3><span style="font-size: 12pt;"><strong>Nice to Have</strong></span></h3>
<p><span style="font-size: 12pt;"><strong>Production experience with a lakehouse table format</strong> (Apache Iceberg or Delta Lake). The specific format matters less than the underlying concepts: you understand how the lake stores data on object storage, how a table format adds transactional semantics on top and how a data warehouse can read that data. You have dealt with schema evolution and table maintenance.</span></p>
<h3><span style="font-size: 12pt;">We care about you</span></h3>
<ul>
<li style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Security & Savings</strong>: Attractive package providing financial peace of mind, including competitive compensation, profit-sharing, daily meal vouchers (Swile), family health insurance (Alan), and a personalized relocation package (if needed).</span></p>
</li>
<li style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Career Development</strong>: Continuous investment in our employees’ skills: in-house and external training, tech conference opportunities, internal mobility (individual contributor or management career ladder).</span></p>
</li>
<li style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Life Balance</strong>: A well-balanced work-life for our employees is one of our top priorities: 35+ days off per year, hybrid work (2 days remote work per week), fully covered parental leave, and reserved daycare places.</span></p>
</li>
<li style="font-size: 12pt;">
<p><span style="font-size: 12pt;"><strong>Wellness</strong>: Prioritizing employee well-being through premium work equipment, enjoyable work environment (work-life balance, team building events, summits), remote work subsidy, promoting Diversity & Inclusion with internal & external initiatives (women speaking groups, dedicated school partnerships), dedicated charitable time and sustainability actions (Eco Tree, subsidy for eco-mobility).</span></p>
</li>
