As a Data Engineer at Stackadapt, your daily work will be highly dynamic and deeply integrated with the platform's core operations. You will spend your time designing, implementing, and maintaining the infrastructure that powers programmatic advertising at scale.

Your primary responsibilities will include:

• Developing Scalable Pipelines – Designing and implementing robust batch and real-time data ingestion pipelines that process terabytes of data daily with high reliability and low latency.
• Optimizing Infrastructure – Continuously monitoring and tuning distributed systems, databases, and query engines to reduce cloud infrastructure costs and improve query performance.
• Collaborating with Data Science – Partnering closely with data scientists to productize machine learning models, ensuring they have access to clean, high-quality features in real time.
• Ensuring Data Quality & Governance – Implementing automated testing, data profiling, and validation frameworks to ensure the accuracy, completeness, and consistency of all downstream data assets.
• Architecting Data Platforms – Designing flexible, self-service data platforms and schemas that enable product managers and analysts to easily extract insights and build reports.

To be competitive for the Data Engineer position at Stackadapt, you must possess a strong blend of software engineering discipline and big data expertise.

• Must-have technical skills – Proficient in at least one major programming language (such as Scala, Java, Python, or Go), with a deep understanding of distributed computing frameworks like Apache Spark, Flink, or Hadoop. You must also have strong SQL skills and experience working with cloud data warehouses (e.g., Snowflake, BigQuery) and streaming platforms (e.g., Kafka).
• Nice-to-have skills – Experience in the AdTech industry (understanding real-time bidding, DSPs, or SSPs), familiarity with Kubernetes and infrastructure-as-code (Terraform), and a solid background in probability and statistics.
• Experience level – Typically, Stackadapt looks for candidates with several years of hands-on experience building production-grade data pipelines and managing large-scale distributed systems.
• Soft skills – Strong analytical thinking, excellent technical communication, a proactive approach to problem-solving, and the ability to thrive in a fast-paced, rapidly evolving environment.

Q: How technical is the initial recruiter or HR screening call? A: Unlike many companies where the first call is purely behavioral, Stackadapt recruiters may ask several basic computer science and technical questions right away. You are expected to answer these questions correctly to proceed to the next round, so be sure to review your fundamentals before the very first call.

Q: What is the primary programming language used by the Data Engineering team? A: While Stackadapt utilizes a variety of technologies, candidates are generally free to use their preferred programming language (such as Python, Java, or Scala) during the coding interviews. The focus is on your problem-solving logic, data structure choice, and algorithmic efficiency.

Q: How heavily does the interview process focus on AdTech-specific knowledge? A: Prior AdTech experience is a valuable asset, but it is not a strict requirement. The interview process is highly focused on core engineering principles, scalability, and problem-solving. If you have strong distributed systems fundamentals, you can easily pick up the domain knowledge on the job.

Q: What is the typical timeline for the hiring process? A: Stackadapt is known for a highly efficient and fast-moving interview process. Candidates often receive feedback within a few days of completing a round, and the entire process—from initial application to final offer—can often be completed in two to three weeks.

• Prepare for immediate technical questions: Do not treat any conversation as "just a chat." Be ready to answer basic computer science questions, explain runtime complexities, or discuss system architecture during any stage of the process.

• Focus on probability and optimization: Practice coding problems that involve probability, statistics, and memorization. These topics frequently appear in Stackadapt technical assessments and require a strong grasp of mathematical logic.

• Communicate your thought process clearly: During coding and design rounds, talk through your reasoning out loud. If you are stuck, explain what you are trying to solve and the trade-offs you are considering. Interviewers value collaborative problem-solving.

• Be ready to discuss real-world scale: When describing your past experiences, use concrete numbers. Detail the volume of data you processed, the query latencies you achieved, the cluster sizes you managed, and the specific cost or performance optimizations you delivered.

The Data Engineer role at Stackadapt offers an incredible opportunity to work on highly challenging distributed systems problems at an immense scale. By building the pipelines that power real-time bidding and programmatic advertising, you will have a direct and measurable impact on the company's core product and business growth.

To succeed in the interview process, focus your preparation on core computer science fundamentals, algorithmic coding (specifically focusing on data structures, probability, and memorization), and scalable system design. Remember that Stackadapt values technical precision, clear communication, and a disciplined approach to problem-solving from the very first screening call.
