About Loop
Loop is industrializing services through AI, starting with one of the world's most complex industries: the global supply chain. We're an AI-native company built to solve the systemic data problem that's held logistics back for decades. Our Logistics Data Platform turns fragmented, unstructured data into a trusted foundation that fuels automation, financial clarity, and decision intelligence at scale. Today, Loop serves >20% of the Fortune 100, manages over $30B in supply chain spend, and helps its clients save hundreds of millions of dollars each year.
We recently closed a $95M Series C and are backed by leading investors including Valor Equity Partners, Founders Fund, 8VC, Index Ventures, J.P. Morgan, and more than 50 industry-leading angel investors.
Our team brings deep expertise from Uber, Google, Microsoft, Meta, Amazon, Flexport, C3 AI, VMware, Box, UPS, and C.H. Robinson and we're looking for builders who want to help shape what comes next.
About You
As an AI full-stack engineer, you will work closely with founders and customers to understand and solve their logistics billing and payment pain points. You will ship features that directly impact customers, and you will do it with AI in two ways: building products with AI, and building the systems that let AI agents and non-technical users deliver technical work that used to require an engineer. The most valuable work here solves a whole category of problems rather than a single one-off feature. You will face and solve many complex technical challenges while you receive guidance and feedback from the team. You will shape the Loop DNA and define how we grow as a company.
Responsibilities
Work cross-functionally with product, design, and sales to understand requirements and ship thoughtful solutions.
Build and ship the AI harness: the data pipelines, schemas, validation, and feedback loops that let agents do work reliably at scale.
Start from the outcome, not the process: curate the harness, data, and success criteria instead of the specific logic, then let agents write and validate it against real data.
Write high-quality code optimized for extensibility, working across component boundaries from frontend to backend, infrastructure, and our AI stack.
Engage in code reviews to maintain a high bar of engineering excellence.
Lead discussions and documentation to communicate and arrive at the best technical design.
Adopt AI technologies such as Cursor/Codex/Claude to accelerate software development and champion adoption of AI tools across the organization for increased productivity.
Promote better practices, share technical knowledge, and help grow Loop through deliberate feedback on product, process, and culture.
Qualifications
Work in the SF office 4+ days a week.
Two years of software engineering experience.
Experience with TypeScript and tools such as GraphQL, Relay, React, and Node.js.
Experience working at early-stage companies where you shipped products end-to-end and wore many hats.
Excited to build with AI and apply it to real customer problems. No prior AI or machine learning background is required; you will learn our AI stack here.
Under the Hood
Infrastructure: AWS, CDK, Fargate ECS
Backend: TypeScript, Node.js, Prisma, NestJS, PostgreSQL, Kafka, Redis, Elasticsearch, GraphQL
Frontend: TypeScript, React, Relay, Ant Design, Vite, GraphQL
