Lead Data Engineer

The Opportunity: Why 1Buy.ai?

We are not just building another procurement tool. We are building the Cognitive Engine for global manufacturing. In a world of fragmented data and brittle supply chains, 1Buy.ai leverages multi-agent AI to automate the discovery, risk-assessment, and procurement of electronic components at a global scale.

We are backed by a founding team that has built, scaled, and exited some of India’s most iconic B2B and SaaS unicorns:

The Role

As Data Architect, you will design and own the data architecture that powers analytics, customer-facing insights, and AI models. You will lead a small, high-impact team of data engineers while staying deeply involved in design and implementation.

This is a builder role. You will be expected to think strategically, but also write production-grade code.

What You’ll Do

• Own end-to-end data architecture across ingestion, transformation, storage, and analytics
• Design and scale batch and streaming pipelines using Python, Airflow, Spark / PySpark, Kafka, dbt, and Debezium
• Architect and optimize data models across MongoDB, ClickHouse, and OpenSearch for high-volume ingestion and low-latency analytics
• Establish strong data quality, validation, and lineage practices using Great Expectations or similar frameworks
• Build clean, well-documented, analytics-ready datasets that power dashboards and AI workflows
• Mentor and guide a small team of 2–3 data engineers, setting standards and driving execution
• Partner closely with product, AI, and platform teams to enable new data use cases and faster experimentation
• Continuously improve performance, reliability, and cost efficiency on AWS

What We’re Looking For

• 5–8 years of experience in data engineering or data platform roles
• At least 1+ year of experience leading or mentoring engineers
• Strong hands-on expertise in Python, Apache Airflow, Spark / PySpark, and MongoDB
• Solid understanding of ETL / ELT patterns, streaming systems, CDC, and scalable data modeling
• Experience designing systems that balance flexibility, performance, and data quality
• Working knowledge of AWS and production performance tuning

Nice to Have

• Exposure to supply chain, procurement, pricing, or marketplace data
• Experience with data contracts, observability, or data SLAs
• Familiarity with privacy and compliance concepts such as GDPR or India DPDP

Why Join 1Buy.ai

• Real ownership of a core platform that directly drives revenue and AI outcomes
• Small, senior team with high autonomy and low bureaucracy
• Problems at real scale with messy, high-value data
• Opportunity to shape how data and AI are used in global procurement
• Work closely with founders who have built and scaled large multi-billion $ SaaS and supply-chain platforms

If you enjoy building data systems that actually get used and matter to the business, you will feel at home here.
