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 a niche 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

• 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. Onsite interview consisting of:
3. • 1-hour system design exercise
   • 45-minute meeting with the product team and company leadership
