Careers
Work on the layer every tokenized instrument is measured against.
A small engineering company in Paris, building the verified contract engine for tokenized markets. We hire slowly and we hire for the long term.
The work
Four kinds of work, one engine.
Every role touches the same object: a specification that becomes exact cash flows, lifecycle events and ISO 20022 messages, with a proof that it does.
- 01
Proof engineering
Proofs per contract family, the checker and the conformance suite.
- 02
Engine and rails
The deterministic core, ISO 20022 message generation and bank rail connectivity.
- 03
Standards and ontologies
Contract meaning agreed before code, in the working groups where the standards are set.
- 04
Academy
Courses that teach analysts and engineers to read the artefacts that make tokenized markets trustworthy.
How we hire
A conversation, a working session, an offer.
No puzzles. We talk about what you have built, then spend a working session on one real instrument together. Decisions are quick and reasons are given either way.
What we look for
People who would rather prove it than argue it.
Formal methods, financial contracts, ISO 20022, distributed ledgers or production infrastructure: deep in one, curious about the others.
- 01
Care about being right
You read the specification before the code, and you write down what you are sure of and what you are not.
- 02
Work in the open
Your work is reviewed, published and run by other people. You like that.
- 03
Speak to institutions
You can explain a proof to an auditor and a coupon schedule to a proof engineer.
Open roles
Roles are published here with their date.
Until a role you fit is listed, write to us with what you have built and what you want to build. Every application is read by an engineer.
