Software Engineering Placement

Iridium is building the infrastructure that scales invoice finance. So that every business can access the money they're already owed. One hard problem at the core of the company. Not a rotation. Payment Intelligence:
Invoices don't get paid the way the terms say they will. Every debtor has a rhythm - who pays early, who pays at 74 days regardless of what the contract says, whose behaviour shifts before they stop paying entirely. You will build the systems that learn that rhythm from real payment histories and turn it into something the rest of the platform can act on.

Collection Policy Generation:
Once you can predict how an invoice will actually be paid, the question becomes what to do about it. You will work on generating the collections policy itself - when to reach out, through which channel, and how hard - and on feeding the same signal back into how we underwrite the next invoice. This is a live problem for our lenders, not a research exercise.

Next.js and React on the front, Python and FastAPI on PostgreSQL and AWS behind it, with heavy use of agentic AI, evaluation pipelines, search & retrieval, and time-series data.

You will not be handed one narrow slice. You will follow the problem wherever it goes. Forward Deployed:
You will get real exposure to the lenders we serve. Sitting in on how they work, seeing which of your assumptions survive contact with an actual credit team, and bringing that back into what you build. Most engineers wait years for that access.

An engineer on the founding team with real ownership of work that ships. Not a rotational internship, and not shadowing.

Around four months over summer 2027. We will fit the exact dates around your course.

Next.js / React, Python / FastAPI, PostgreSQL, AWS. Agentic AI, evaluation pipelines, search & retrieval, time series.

Students at any university on a placement year, year in industry, or summer internship. Solid coding ability, comfortable reading documentation, and genuinely curious about AI and LLM systems.

In-person in New York.

We sponsor visas and cover relocation for international applicants.
