We are looking for a Senior Data Engineer to help build the next generation of our cloud data platform. This role is ideal for an engineer who thrives on solving complex data challenges at scale and brings deep expertise in Databricks, AWS cloud services, and modern data integration. You will design and operate high-performance, cloud-native data pipelines and analytics systems that power mission-critical workloads across our Ad Stack and external data ecosystems.
If you are energized by distributed systems, platform thinking, automation, and building reliable data products in a fast-moving environment, this is an opportunity to make meaningful technical impact. Join a team where you’re empowered to unleash your full potential by working with the most cutting-edge concepts in Ad-Tech.
Responsibilities
Troubleshooting: Identify and resolve production issues, optimize performance, and address bottlenecks in data processing.
Build Scalable Data Products: Design, build, and optimize cloud-native data pipelines using Databricks, Spark, SQL, and Python to support large-scale ingestion, transformation, and delivery of high-value data across the platform.
Own Platform Reliability and Scale: Advance our cloud data platform with AWS services and strong engineering field, improving scalability, observability, resilience, cost efficiency, and operational excellence.
Lead with Technical Depth: Apply deep expertise in Databricks, AWS, SQL, Python, Linux, and cloud integration patterns to solve complex engineering problems and influence architecture decisions.
Partner Across Functions: Collaborate with cloud architects, integration engineers, analysts, and product partners to deliver data solutions that are scalable, maintainable, and aligned to business outcomes.
Drive Continuous Improvement: Continuously improve data engineering standards, developer productivity, automation, and platform capabilities by introducing modern tools, patterns, and guidelines.
Communication: Clearly articulate technical concepts and solutions to internal teams and partners, fostering a collaborative environment.
Qualifications
BA/BS in Computer Science or related field.
6-8 years of experience in data engineering, cloud data platform engineering, or large-scale data systems.
Strong track record of delivering production-grade solutions using Databricks, AWS, SQL, Python, and modern ETL/ELT frameworks.
Proficiency in working with Databricks, Spark, SQL, and Python from previous professional positions.
Hands‑on experience with AWS cloud services, Linux, workflow orchestration, and modern data pipeline development in cloud‑native environments.
Deep understanding of distributed systems, cloud data architecture, data warehousing, and integration patterns.
Experience with Kafka, Airflow, Docker, Kubernetes, relational and NoSQL databases, and enterprise‑scale data platforms is highly valued.
Strong communication, problem‑solving, and ownership approach, with the ability to work effectively across teams and contribute in a high‑performance engineering environment.
