138d•$145,000 - $205,000•Onsite

About The Position

As an AI full-stack engineer, you will work closely with founders and customers to understand and solve logistics billing and payment pain points. You will ship customer-impacting features using AI both to build products and to create systems that let AI agents and non-technical users deliver technical work that previously required an engineer. The role focuses on solving broad categories of problems rather than one-off issues, while tackling complex technical challenges with guidance and feedback from the team. You will help shape Loop’s culture and how the company grows.

Requirements

Work in the NYC office at least 4 days a week.
At least two years of software engineering experience.
Experience with TypeScript and tools such as GraphQL, Relay, React, and Node.js.
Experience at early-stage companies shipping products end-to-end and taking on varied responsibilities.
Interest in building with AI and applying it to real customer problems.

Responsibilities

Work cross-functionally with product, design, and sales to understand requirements and ship thoughtful solutions.
Build and ship the AI harness, including data pipelines, schemas, validation, and feedback loops that let agents work reliably at scale.
Curate the harness, data, and success criteria around desired outcomes, then let agents write and validate solutions against real data.
Write high-quality, extensible code across frontend, backend, infrastructure, and the AI stack.
Participate in code reviews and maintain a high bar for engineering excellence.
Lead discussions and document technical designs to communicate and reach effective solutions.
Adopt AI technologies such as Cursor, Codex, and Claude to accelerate software development and champion AI tool adoption across the organization.
Promote better practices, share technical knowledge, and provide deliberate feedback on product, process, and culture.
