Company

A founder who wrote the specification.

Nexara is built by people who have run counterparty risk and sold to the institutions that carry it — and who published the reasoning before building the product.

Careers

Encode expertise into production systems.

01

The work is unusual.

A forward-deployed engineer at Nexara sits with the institution, learns how its desk actually reasons about a counterparty, and encodes that judgement into a system that then has to survive model validation.

02

What you build compounds.

It is neither pure consulting nor pure product engineering. What you build for one client becomes part of the engine every subsequent client inherits — which is why the standard for what ships is higher than a bespoke deliverable would require.

Roles and briefings shared on request

Sixty minutes, on the real platform.

Architecture walkthrough, paper review, and a live product session — not a slide deck. Under NDA.
