Founding Engineer

Dexter is the AI-native spend intelligence platform for complex enterprises. Big enterprises spend hundreds of millions, sometimes billions, every year buying things from suppliers, but most of them have no clear picture of what they're actually paying for. We use AI to read their invoices and contracts and turn that messy data into clear insights, so they can spot savings and make smarter decisions.

Procurement is a fascinating function, responsible for huge amounts of spend, managing strategic supplier relationships and negotiations, yet is overlooked when it comes to technology. We’re here to bring them into the AI era.

We went through Y Combinator in 2024, and have been growing since then. Now we're looking for a Founding Engineer to scale our engineering team, with a strong focus on using AI and automation to move faster than teams ten times our size.

Role description

As a founding engineer, you’ll work on building the Dexter product from the ground up, collaborating closely with the founders and our customers.

It’s not just about shipping code, but rather owning projects end-to-end, making product and technical decisions, talking to customers, and making Dexter a successful business.

Some of the problems we currently solve for our customers include structured data extraction from documents (invoices, contracts, etc), autonomous agents matching documents and entities together, and AI assistants assisting them in their tasks. It’s the full range of applied AI in the enterprise.

About us

We’re a team of builders and operators who love solving tough problems. Our founders, Vincent (ex-SoundCloud), Caterina (ex-Uber), and Bella (ex-HubSpot), met while scaling operations at Dance and saw firsthand how critical supply chain and procurement operations are to real-world products. So we built Dexter to help. We’re backed by Y Combinator and growing fast.
