Title and Summary

Lead Cloud Engineer

Overview:

Interested in building the next generation cloud data ecosystem that processes petabytes of data and powers AI-driven insights for some of the world's largest brands?

The Marketing Services Technology team is transforming its analytics and data platform from traditional on-premises Hadoop environments to a modern cloud-native architecture powered by AWS, Databricks, Apache Spark, Iceberg, and AI technologies. We are looking for a Lead Cloud Data Engineer who is passionate about cloud engineering, Big Data, distributed systems, and modern data platforms.

This role works at the intersection of Cloud, Data Engineering, Analytics, and AI. You will design and deliver scalable, secure, and high-performing data solutions that support advanced analytics, machine learning, and business growth at global scale.

The ideal candidate has hands-on experience with modern cloud technologies as well as large-scale Big Data systems, including Hadoop and Spark, and is equally comfortable architecting cloud-native solutions, developing data pipelines, optimizing distributed workloads, and driving the modernization of enterprise data platforms.

Build modern cloud data solutions. Enable AI and analytics at scale. Shape the future of data-driven marketing.

Role:

• Design, develop, and support large-scale cloud-native data solutions on AWS and Databricks.
• Build and maintain batch, streaming, and real-time data pipelines supporting analytics, reporting, machine learning, and AI workloads.
• Engineer scalable distributed data processing systems using Apache Spark and related Big Data technologies.
• Design and implement modern Lakehouse architectures leveraging Databricks, Delta Lake, and Apache Iceberg.
• Lead modernization initiatives migrating data workloads from Hadoop-based platforms to cloud-native architectures.
• Develop reusable frameworks and engineering patterns that improve scalability, reliability, and operational efficiency.
• Partner with Architects, Product Managers, Data Scientists, and Software Engineers to define and implement cloud data solutions.
• Evaluate technologies and approaches for data ingestion, transformation, storage, governance, and consumption.
• Implement best practices around security, governance, performance optimization, observability, and cost management.
• Drive automation using Infrastructure-as-Code, CI/CD pipelines, and modern software engineering practices.
• Contribute to the evolution of Marketing Services' cloud and data strategy while enabling future AI and machine learning capabilities.

All About You:

• Strong hands-on experience with Big Data technologies including Hadoop, HDFS, Hive, Spark, and related distributed computing frameworks.
• Deep expertise in cloud data engineering on AWS, including storage, compute, networking, security, and scalable data architectures.
• Experience designing and developing modern data solutions using Databricks, Spark, Delta Lake, and cloud-native technologies.
• Proficiency in Python, Java, or Scala, building large-scale distributed data processing applications.
• Experience building robust batch and streaming pipelines supporting high-volume and high-velocity workloads.
• Understanding of modern Lakehouse architecture principles and open-table formats such as Apache Iceberg and Delta Lake.
• Skilled in data modelling, schema design, partitioning strategies, query optimization, and performance tuning.
• Familiarity with enterprise-scale data governance, security, privacy, and compliance, working with structured and unstructured datasets at scale.
• Experience with Infrastructure-as-Code (e.g., Terraform), modern CI/CD, and cloud-native monitoring and observability practices.
• Strong analytical and problem-solving skills, a passion for automation, and the ability to assess emerging technologies and recommend scalable, cost-effective solutions.
• Excellent communication and collaboration across technical and business teams; comfortable in Agile/Scrum environments managing multiple priorities.
• BS/MS degree in Computer Science, Software Engineering, Information Systems, or a related field.

Preferred Qualifications:

• Experience with Databricks on AWS in enterprise production environments.
• Experience migrating workloads from Hadoop or Cloudera ecosystems to modern cloud architectures.
• Hands-on experience with Apache Kafka, Flink, or other event-streaming technologies.
• Experience supporting Machine Learning, MLOps, or AI-driven data platforms.
• AWS and/or Databricks certifications.
• Familiarity with FinOps and cloud cost optimization practices.
• Experience working with petabyte-scale data environments.

Questions you could be asked

How do you monitor a model once it's live, and how do you know it needs retraining?
Walk me through how you've used Databricks in your day-to-day work.
Describe a typical day in a role like this one: which parts run through AI directly?
If you removed AI from this role, what would be left, and how do you decide what still needs a human?

Adapt your resume

List these exact terms on your resume: Ml Ops and Databricks. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
Show where AI is part of your daily process, not a one-off project — this role expects it to be a running habit.
