About Us

Global trade still runs on outdated, manual workflows - we are fixing that by building AI agents for the logistics industry. Our AI works alongside humans, automating document-heavy tasks so companies can process shipments faster and with fewer errors.

We have moved past the "zero-to-one" phase and have achieved clear product-market fit. We are currently seeing rapid traction with >100% MoM revenue growth and are already deployed with customers processing meaningful operational volume. We've raised $5M from First Round Capital and Pear VC and are now scaling our platform's breadth and depth. Our deeply technical team comes from Google, LinkedIn, Salesforce and top schools and AI research labs.

The Role

We are looking for a Senior Fullstack Engineer who thrives at the intersection of high-velocity execution and complex systems design. As we scale, you will own the evolution of our AI-driven platform, turning "messy" logistics workflows into crisp, high-performance product experiences.

This is a high-leverage role for a technical leader who wants to bridge the gap between sophisticated backend AI data and the human operators who rely on it. You won't just be shipping features; you will be defining the architectural standards that allow our team to move faster as we grow.

What You’ll Do
  • Architect Scalable Systems: Design and lead the migration of our frontend architecture to support real-time, data-heavy dashboards using TypeScript, React, and Tailwind CSS.

  • Design Human-in-the-Loop AI: Build intuitive interfaces that make AI outputs and automated workflows transparent, explainable, and easy for operations teams to manage.

  • Drive Velocity & Quality: Take full ownership of the product lifecycle - from technical discovery and scoping to production monitoring - ensuring we maintain a high "ship rate" without sacrificing reliability.

  • Technical Leadership: Define the technical vision, mentor new hires, and foster an elite engineering culture.

  • Complex Problem Solving: Tackle the "edge cases" of global trade, ensuring our core services maintain high uptime while handling unpredictable real-world document inputs.

Who We’re Looking For
  • Senior Expertise: 6–8+ years of professional software engineering experience, with a proven track record in high-growth, fast-paced environments.

  • Frontend Mastery: Deep proficiency in TypeScript and React, with the ability to architect complex state management for data-intensive applications.

  • Full-Stack Depth: Strong command of Python for backend services and advanced SQL (PostgreSQL) for database design and query optimization.

  • Bias for Action: You are a "builder" who prefers shipping over over-engineering. You write crisp requirements and drive cross-functional delivery with minimal supervision.

  • AI Fluency: Experience (or a deep interest) in integrating AI APIs and handling complex document extraction workflows.

  • In-Person Collaboration: You are energized by working shoulder-to-shoulder with founders in our San Francisco office.

Success Metrics
  • Architectural Velocity: Ability to move from concept to production-ready systems within aggressive startup cycles.

  • System Resilience: Maintaining high uptime and low error rates for core logistics services during periods of massive scale.

  • Product Impact: Measurable improvement in logistics efficiency and user adoption of AI-driven features.

Perks
  • Founder-level impact and meaningful equity during a period of massive scale.

  • Free office lunches and dinner.

  • Comprehensive health insurance and 401k plan.
