About the Role
A fast-moving, pre-seed AI recruiting marketplace is looking for a Founding Engineer (AI/ML) to own the intelligence layer of their product. You'll architect and ship recommendation systems, ranking algorithms, and LLM-powered matching that connects top talent with the right opportunities — at the very core of what the product does. This is a foundational, high-ownership role at a small, ambitious team backed by notable investors and angels from top-tier VC firms.
This role is well-suited to someone who thrives in a scrappy, high-velocity startup environment, ships daily, and has something exceptional on their profile that sets them apart.

Build and own the AI/ML intelligence layer, including recommendation systems and ranking algorithms.
-
Develop LLM-powered matching to improve candidate–role alignment in production.
-
Architect and maintain production-grade data pipelines and services integrated with the core stack.
-
Collaborate cross-functionally to translate product goals into shipped features.
-
Deliver end-to-end features with full ownership, shipping to production on a daily cadence.

Required skills & experience:

-
Experience building and maintaining production data pipelines and services.
-
Comfortable in fast-paced startup environments with rapid iteration and daily shipping cycles.

Proficiency with Cursor, Typesense, and trigger.dev (or comparable tools) in production-grade projects.
Nice to have:
-
Experience with Typesense or similar search/ranking infrastructure.
-
Experience with trigger.dev or similar workflow automation tools in production.
-
Demonstrated exceptional technical achievement — top university academic record, strong open-source contributions, or notable personal/side projects.
Culture fit:
-
Openness to collaborative, in-person hackerhouse-style working environments, including potential time in Latin America.
-
Willingness to work 6 days per week in a high-intensity, early-stage environment.
