Role
Who you are
- We are not looking for just “straight-A students." We are looking for obsessive builders with spikes. If the following resonates, you belong here:
- You build on nights and weekends. You have a repo, a side hustle, or a project you built just because you are curious
- You don't wait for class assignments to write code.You hate waiting for approval
- You prefer to ship, break, fix, and apologize rather than wait for a committee decision
- You are bored by easy tasks. You want problems that are more than 1 prompt away from a solution
- You grind to win. You are the type to skip social events just to climb the Esports ladder, ace a math competition, or debug a complex issue, purely for the joy of mastery
- Pursuing a BS or higher in STEM fields; available to start full-time in 2027-2028
- Working in person in the SF, Chicago, or NYC office 4 days a week
- Proficiency with modern techstack
- AI Literate. You have strong intuition on how LLMs work: where they excel and where they generate slop. You live and breathe AI native tools (Cursor, Codex, Claude Code etc.)
What the job involves
- This role has two tracks: AI and fullstack engineering
- Most AI stays in the browser. Ours moves atoms. You aren't just building features; you are building the autonomous brain for the Fortune 100’s global supply chain
- This program is designed to compress 12 months of learning into 12 weeks by throwing you into the deep end of production AI systems on Day 1
- Instead of sandboxed projects, you get to solve real problems and impact customers directly
- This program demands intense investment, but by the end, you will perform as a strong entry-level engineer jumpstarting your career
- Week 1 (Onboarding): Deep dive into tools and domain. You will ship code to production on Day 1 and fully grasp our dev loop by Friday
- Week 2-4 (Project 1): You will finish your first project, which matches a typical entry-level engineer’s initial project
- Week 5-8 (Project 2): Your second project will have more ambiguity, and you will take on more autonomy in completing this project
- Week 9-11 (The stretch goal): Your third project comes with bigger scope and more ambiguity, typically expected of mid-level engineers
- This is the stretch goal. We do not expect everyone to finish this project. But we expect you to try your best!
- Week 12 (Demo & reflection): You present your work to the exec team and engineering org, detailing the technical tradeoff and business impact. You capture your experience as an engineering blog
- Ship critical infrastructure. Manage real-world logistics and financial data for the largest enterprise in the world
- Full-stack proficiency. Work across system boundaries, from frontend UX to LLM agents, database schema and event infrastructures
- Leverage AI tools to handle the 90% boilerplate, so you can focus the highest leverage 10%: quality, architecture, product taste
- Fireside chat and code reviews from the exec leadership team
- Direction interaction with customers and production data
- Fulltime offer. If you crush the stretch goal, you will have a return offer post graduation
Our take
In the complex landscape of global supply chains, outdated financial infrastructure and manual processes have created a significant challenge for businesses in the logistics sector. Legacy systems often rely on labor-intensive methods for recording crucial shipping documents, leading to poor auditing practices and a lack of a single, reliable "source of truth" for payment transactions.
Loop, an audit and payment platform, is actively addressing these challenges with its AI-driven approach to transportation financial data. The company's platform consolidates and analyses information, providing real-time insights into costs, improving accuracy, and unlocking savings for its users.
In a 2023 milestone, Loop raised $35 million in a Series B funding round. This investment attests to the growing recognition of its value proposition and its potential to transform how money moves through the supply chain. With an expanding customer and partner base (that in 2024 grew to include Saudi Arabia through a partnership with Mastercard and JP Morgan through a supply chain payments partnership) and over $3 billion in booked total payment volume to date, Loop is poised for further growth and innovation.
