Job description

Company Description

Mercator is building AI agents that coordinate global supply chains. Today’s systems leak $1.7T in waste each year in retail alone -- in overproduction, lost revenue, and unnecessary emissions.

Mercator’s founders are seasoned technical operators with a decade of experience leading cutting-edge AI and simulation efforts across Google (Gemini, Tensorflow, Google X).

Role Description

As our first full-stack engineer, you’ll build the interface that brings our simulation platform to life and redefines what usability looks like in a category historically dominated by Excel. You’ll design and ship consumer-grade experiences that make complex operational decisions feel simple, intuitive, and fast. A major part of this role is driving mindset and behavior change through UX: helping users shift from static spreadsheets to interactive, scenario-driven systems.

You’ll work directly with customers to understand real workflows, translate them into modern product patterns, and own the full stack across Next.js and NestJS. A critical part of the job is listening carefully to what customers ask for, recognizing when requests point in the wrong direction, and extracting the underlying workflow problem they’re actually trying to solve.

You’ll collaborate closely with the engineer building our simulation engine to ensure advanced system output becomes clear, actionable, and trustworthy. You’ll be defining not just our product, but the way an entire industry interacts with operational data.

Benefits

• Comprehensive health, dental, and vision insurance
• As a company we’ll work from a fun destination (think: skiing, surfing) two weeks a year
