pul liWe 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 /li liWe 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 /li liWe operate at the intersection of business and technology, supporting critical domains including Finance, RD (Research and Development), GTM (Go-to-Market), MS (Manufacturing Supply), Spend…. Our pipelines power the Aily App across multiple tenants, delivering the insights that drive general enterprises in several industries /li liScale: Managing multi-tenant by design with config-driven pipelines and models that adapt to diverse client needs /li liReliability: Ensuring 24/7 uptime through automated QA, validations, and proactive monitoring /li liQuality: Implementing sophisticated business logic checks to maintain a “Single Source of Truth.” /li liGovernance: Orchestrating complex event-driven and scheduled flows while maintaining strict data security and compliance /li liData is our product. We work as strategic partners: /li liWith Product: To define and refine features that solve real-world problems /li liWith Software Engineering:



Establishing clear Data Contracts to ensure seamless integration with the Aily App /li liWith ML Data Scientists: Engineering the high-performance datasets required to transform raw data into measurable AI impact /li liWe leverage a modern, code-first data stack to maintain agility and high standards: /li liLanguages 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 /li liData Transformation Modeling: We use dbt for our SQL-based transformation layer and SQLModel with Alembic for ORM-based schema management and versioned migrations /li liStorage Analytics: Besides PostgreSQL / RDS, we utilize DuckDB and DuckLake as our embedded analytics engine, all hosted on a robust AWS infrastructure (S3, IAM) /li liOrchestration Workflow: Apache Airflow handles our complex event-driven and scheduled job flows /li liQuality Engineering Excellence: We prioritize reliability through pytest for QA validations, GitHub for version control, and a rigorous PR-based code review process /li liDesign and implement end-to-end data pipelines (ingestion → transformation → quality → delivery) for multiple use cases with growing autonomy /li liBuild and maintain data components (event-driven ingestion, transformations,



APIs, catalogs) using modern data tools /li liWrite SQL-first transformations (dbt layers + normalization framework) and Python where orchestration/API logic needs it /li liImplement robust data quality as early as possible in the pipeline (shift-left approach) for validation, monitoring, and alerting systems at scale /li liOptimize data models for performance, cost and reliability across multiple datasets /li liCollaborate with Junior/Intern team members on Data craft best practices and tooling /li /ul h3Benefits /h3 ul liGlobal company and culture /li liFast growth path /li liHybrid working model /li /ul pHands-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. Python for services/pipelines (not notebook‑only analytics). Comfort with git, PR reviews, pytest. Startup mindset: thrives in ambiguity, proactively solves complex data challenges, and improves tooling beyond your immediate scope. Ready to lead boldly – building the data foundation that enables Aily’s AI platform to deliver millions of real‑time insights, briefings and agentic responses daily. Strong SQL (complex joins, aggregations, incremental patterns). Interest in business domain (not just infra). Strong collaborators who partner with Data Practitioners, Data Scientists, Software/ML Engineers, Product teams, and business stakeholders to turn raw data into actionable customer insights. /p /p #J-18808-Ljbffr
