Envíe su CV y cualquier información adicional requerida después de haber leído esta descripción, haciendo clic en el botón de solicitud.- We are looking for Data Practitioners (Mix of Data Engineer and Analytics skills) who are passionate about building reliable, scalable data solutions that power enterprise-grade AI: people who make data accessible, trustworthy and ready for ML, ensuring our decision intelligence platform can serve millions of insights every day
- We are the backbone of Aily’s “Data-to-Decision” engine. We build and own the complete data lifecycle—from ingestion and transformation to quality and delivery. Our team develops the robust models, APIs and scalable infrastructure that ensure high-quality data is always available for the Aily App and our AI models
- We operate at the intersection of business and technology, supporting critical domains including Finance, R&D (Research and Development), GTM (Go-to-Market), M&S (Manufacturing & Supply), Spend…. Our pipelines power the Aily App across multiple tenants, delivering the insights that drive global enterprises in several industries
- Scale: Managing multi-tenant by design with config-driven pipelines and models that adapt to diverse client needs
- Reliability: Ensuring 24/7 uptime through automated QA, validations, and proactive monitoring
- Quality: Implementing sophisticated business logic checks to maintain a “Single Source of Truth.”
- Governance: Orchestrating complex event-driven and scheduled flows while maintaining strict data security and compliance
- Data is our product. We work as strategic partners:
- With Product: To define and refine features that solve real-world problems
- With Software Engineering: Establishing clear Data Contracts to ensure seamless integration with the Aily App
- With ML & Data Scientists: Engineering the high-performance datasets required to transform raw data into measurable AI impact
- We leverage a modern, code-first data stack to maintain agility and high standards:
- Languages & Frameworks: Python is our core for pipelines, APIs, and CLI tooling. We use FastAPI and Pydantic to serve typed, high-performance REST APIs to our platform
- Data Transformation & Modeling: We use dbt for our SQL-based transformation layer and SQLModel with Alembic for ORM-based schema management and versioned migrations
- Storage & Analytics: Besides PostgreSQL / RDS, we utilize DuckDB and DuckLake as our embedded analytics engine, all hosted on a robust AWS infrastructure (S3, IAM)
- Orchestration & Workflow: Apache Airflow handles our complex event-driven and scheduled job flows
- Quality & Engineering Excellence: We prioritize reliability through pytest for QA validations, GitHub for version control, and a rigorous PR-based code review process
- Design and implement end-to-end data pipelines (ingestion → transformation → quality → delivery) for multiple use cases with growing autonomy
- Build and maintain data components (event-driven ingestion, transformations, APIs, catalogs) using modern data tools
- Write SQL-first transformations (dbt layers + normalization framework) and Python where orchestration/API logic needs it
- Implement robust data quality as early as possible in the pipeline (shift-left approach) for validation, monitoring, and alerting systems at scale
- Optimize data models for performance, cost and reliability across multiple datasets
- Collaborate with Junior/Intern team members on Data craft best practices and tooling
Benefits
- Global company and culture
- Fast growth path
- Hybrid working model
Hands-on builders with: Data Engineers / Data Analysts with 2 to 4 years of experience who excel at building reliable, scalable data models and pipelines that power AI decision‑making at enterprise scale.
