Job description

Our client is a fast-growing, venture-backed technology company that has built a modernized Point-of-Sale (POS) platform purpose-built for the wine and liquor retail industry. Two years in, they have achieved meaningful scale - serving 150+ multi-location enterprise customers with a system that operates around the clock across multiple time zones, acting as the core platform for procurement, transactions, and reporting.
They work fully in-person, 5 days a week, out of their office in the Flatiron district of New York City. Relocation assistance and visa sponsorship are not available at this time.
Who They're Looking For
As a Senior Engineer, you'll be expected to bring strong engineering principles backed by at least 5 years of experience. The ideal candidate:
  • Has a strong computer science and programming foundation - has read Designing Data-Intensive Applications
  • Is a craftsperson who deeply cares about the quality of their output and understands the long-term costs of shortcuts
  • Builds with the end user and longevity in mind - knows how to design abstractions and APIs that are a pleasure for both customers and teammates to use
  • Communicates effectively to drive clarity and alignment across the organization - able to translate product requirements into technical challenges and vice versa
  • Is genuinely passionate about software engineering and dives deep into topics that interest them, whether that's the Node.js Event Loop or how virtual memory works at the OS level
  • Has hands-on experience with serverless architectures - comfortable designing and deploying serverless functions and event-driven systems in cloud environments (e.g., AWS Lambda, Vercel Edge Functions, or equivalent)

What You'll Work On
  • Build and own new user-facing features end-to-end, from database models to UI components
  • Continuously improve observability across existing systems - analytics, monitoring, and alerting
  • Collaborate with product and engineering to architect key differentiators, including embedded fintech products and AI agents to help merchants manage their stores
  • Build CI/CD pipelines and developer tooling (e.g., feature environments) that increase development velocity
  • Help shape engineering processes to support building a world-class product

Tech Stack
Familiarity with every tool isn't required, but candidates should have the foundational knowledge to understand what powers them under the hood:
  • Node
  • React
  • Next.js deployed on Vercel
  • Typescript
  • AWS (particularly RDS)
  • PostgreSQL
  • Terraform or equivalent infrastructure-as-code tooling

Compensation & Benefits
  • Salary: $180K-$220K + meaningful equity, depending on experience
  • Unlimited PTO
  • Full benefits package: medical, dental, vision, 401(k), transportation, and more

Interview Process
  1. One or two 30-minute introductory calls with the engineering team
  2. A take-home exercise to showcase your skills and tooling
  3. Onsite interview consisting of:
    • 1-hour system design exercise
    • 45-minute meeting with the product team and company leadership
  4. Offer
