Who are we?

Founded in 2023, Santé is a modernized Point-of-Sales (POS) system serving wine and liquor store businesses. With modernized POS systems being revitalized across the food service industry and general consumer retail, this one-size-fits-all approach falls short within the beverages industry creating a market opportunity.

Two years into the business, Santé has developed full vertical integration tailored to this market segment, driving value for 150+ enterprises hosting multiple locations each. With usage around the clock and across multiple timezones, Santé serves as the main artery for our customers to procure, transact and report on all aspects of their business. 

We work in-person, 5 days a week, out of our office in Flatiron in NYC. We are not considering any relocation or sponsorship at this time.

Who are we looking for?

As a senior engineer, we expect strong engineering principles built from at least 5 years of experience. Our ideal candidate:

  • Has a strong computer science and programming background. They have read DDIA.
  • Is a craftsperson. They deeply care about the work they put out, they did not buy into 2025’s “vibe coding” hype because they know the effects it will have on quality
  • Builds with the end user and longevity in mind. They know how to build good abstractions and APIs that are a delight for both customers and teammates to use
  • Communicates effectively to drive clarity and alignment across the company. They are able to translate product requirements into technical requirements/challenges and vice versa
  • Is genuinely interested in software engineering. They dive deep into topics that interest them, whether it be the Node.js Event Loop or how virtual memory works in an OS.

What you’ll work on?

  • Build and own new user-facing features from the ground up, starting with database models to UI components
  • Make continuous efforts to improve observability into our existing systems by ensuring our analytics, monitoring, and alerting is in a good place
  • Collaborate with product and engineering to architect and scope key differentiators we want to build including embedded fintech products and AI agents to help merchants manage their stores
  • Build CI/CD pipelines and developer tools like feature environments that unlock development velocity
  • Help shape our engineering processes to allow us to build a world-class product

Compensation and benefits
