Senior Full Stack 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 Full Stack Engineer, you'll have significant ownership over our product development. You'll ship features that directly impact our customers' operations, working closely with our founding team to build a best-in-class platform. This is an opportunity to be a key technical voice in a fast-growing startup where your decisions matter from day one.

You will be reporting to Derrick Staten, CTO.

  • Own and ship high-impact features end-to-end, from architecture to deployment

  • Build intuitive, responsive interfaces that make complex supply chain data actionable for restaurant operators

  • Collaborate directly with founders and customers to shape product direction based on real-world needs

  • Make architectural decisions that will scale with the company

  • Drive technical excellence through code review and best practices

  • Expand and maintain our end-to-end test framework to ensure product reliability

Requirements

  • 2-5 years of full stack engineering experience, ideally at Series A-F startups

  • Strong proficiency in React, TypeScript, Next.js and modern frontend development

  • Experience with server-state management in React using TanStack Query / React Query (or similar libraries such as SWR or Apollo Client)

  • Track record of shipping production features with real user impact

  • Self-starter mentality with strong ownership and follow-through

  • Excellent communication skills and collaborative mindset

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

Nice to Have

  • Familiarity with AI/ML product features

  • Background in B2B SaaS products

  • Experience with Python and cloud infrastructure (AWS/GCP)

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
