Senior Data Engineer

Location: New York City (3 days/week in-office)
Employment Type: Full-time

About Us

We're building an AI-native supply chain operating system for restaurant chains. We use AI to automate planning, inventory management, and spend optimization, driving higher sales, lower COGS, and saving team time. SightlineOS was co-founded by Yusha Hu, who previously led supply chain and procurement teams at Chipotle, sweetgreen, and HelloFresh, and Derrick Staten, who was technical cofounder of The League and an engineer and head of product at Branch as it scaled from zero to a $4B valuation.

The Role

As a Senior Data Engineer, you will own the core data foundation that powers forecasting, inventory intelligence, and financial insights across the platform. You will work closely with AI/ML, product, and full stack engineers to turn raw real-world supply chain data into reliable, scalable systems that customers trust. You will also work directly with customers during implementations to understand their data, troubleshoot issues, and ensure successful onboarding.

This is a high-ownership role where your architectural decisions directly impact model performance, product reliability, and customer outcomes, and where clear communication with both technical and non-technical stakeholders is essential.

You will be reporting to Louis Bensard, Head of AI & ML.

What You'll Do

  • Design and own scalable data pipelines ingesting high-volume, granular supply chain data

  • Build and maintain reliable ETL/ELT workflows for forecasting, inventory, and financial use cases

  • Develop clean, well-modeled datasets that power ML models and customer-facing analytics

  • Ensure data quality, freshness, observability, and correctness across the platform

  • Partner with AI/ML engineers to support training, inference, and evaluation workflows

  • Make architectural decisions that scale with customer growth and data complexity

  • Improve performance, reliability, and cost efficiency across the data stack

  • Collaborate directly with founders and customers to understand real operational data needs

Requirements

  • 3-5 years of data engineering experience, ideally at Series A–F startups

  • Strong experience with Python and SQL in production environments

  • Hands-on experience building and operating data pipelines at scale

  • Experience with modern cloud data infrastructure (e.g. AWS, GCP, or similar platforms)

  • Experience with modern data warehouses and transformation workflows

  • Strong understanding of data modeling for analytics and machine learning

  • Ownership mindset with a track record of shipping reliable systems

  • Clear communicator who collaborates effectively with engineering, product, and clients

  • Willing to work in-person in NYC 3 days per week

Nice to Have

  • Experience supporting ML training and forecasting systems

  • Experience with AWS (e.g. S3, Redshift, Glue, Lambda, IAM)

  • Background in supply chain, operations, or time-series data

  • Familiarity with streaming or near-real-time data systems

  • Experience with data quality, lineage, and observability tools

What We Offer

  • Meaningful equity as an early team member

  • Competitive salary

  • Work on cutting-edge agentic AI applications solving real-world problems

  • Real ownership and autonomy over technical decisions

  • Direct access to founders with experience at Chipotle, sweetgreen, HelloFresh and Silicon Valley technology startups

  • The chance to build foundational technology that will scale with the company

  • Small, focused team where your impact is immediate and visible
