Intro 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. 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. Your Mission Key Responsibilities End-to-End Pipeline Engineering: Design and deploy robust transformation pipelines for high-volume data (TB scale). You are responsible for the full lifecycle: ingestion, transformation, testing (unit/integration), deployment, and monitoring. Architecture & Optimization: Take ownership of data modeling and architectural decisions. You will actively refactor legacy code to improve performance and reduce cloud compute costs (e.g., optimizing Athena/Snowflake/Redshift clustering or AWS Glue jobs). Software Engineering Best Practices: Elevate the team's technical standards by implementing CI/CD workflows, containerization (Docker), and rigorous automated testing. You ensure that "it works on my machine" is never an excuse. Data Quality & Observability: Instead of just building business dashboards, you build infrastructure monitoring. You will implement alerts and checks (e.g., dbt tests, Great Expectations) to catch data quality issues before they reach stakeholders. Technical Leadership: Mentor junior engineers through code reviews and technical planning. You will be the voice of engineering rigor within the squad. Your Profile We are looking for a Senior Data Analytics Engineer who approaches data with a software engineering mindset. You will join our Data Solutions squad to architect, build, and maintain production-grade data platforms. This is not a Data Analyst role. While you will understand the business context, your primary focus is technical: designing scalable architectures, writing clean and testable Python/SQL code, automating deployments, and optimizing cloud infrastructure. You will act as a technical standard-bearer, ensuring our pipelines are reliable, cost-effective, and maintainable. We are looking for a candidate who has strong analytics engineering experience or has a strong background in backend development focused on data. Must-Have Skills 4 years of experience specifically in Analytics Engineering or Data Engineering. Advanced Python proficiency beyond scripting: You write modular, object-oriented, and production-ready code. You use relevant libraries and framework for testing, and understand exception handling and logging. Deep expertise in SQL & dbt: You don't just write queries; you build scalable data models (Jinja templating, macros, incremental strategies) and understand query execution plans to optimize performance. Software Engineering Fundamentals: Proven experience with Git flows, CI/CD pipelines (e.g., GitHub Actions, GitLab CI), and Containerization (Docker). You understand how to deploy code reliably. AWS Cloud Native Experience: Hands-on experience building serverless architectures using AWS Lambda, StepFunctions, Glue, and Athena. Testing Mindset: You can demonstrate experience implementing Unit Tests and Integration Tests for data pipelines. You do not rely on manual checks or stakeholder validation for quality assurance. Data Warehouse Ops: Deep understanding of warehousing architecture (Snowflake, Redshift, or BigQuery), including partitioning, clustering, and cost governance. Nice-to-Have Skills Experience with Infrastructure as Code (Terraform) to manage cloud resources. Experience with orchestration tools like Airflow, Dagster, or Prefect. Knowledge of big data processing frameworks (Spark/PySpark). Familiarity with dashboarding tools (Streamlit, Preset, Tableau e.t.c) – Note: This is helpful for debugging and monitoring, but not the core function of the role. B.S. or M.S. in Computer Science, Engineering, Mathematics or other relevant fields. Why us?
