Work on a hard problem with a small team
Custodian is an early-stage Swiss startup. We do not always have a specific opening, but we build across four disciplines and want to hear from people who care about this problem.
Four disciplines, one product
ML and NLP engineering
Signal extraction from conversation data, fine-tuning and evaluation, de-identification pipelines, and work on open models such as Apertus.
Full-stack engineering
The dashboards, the browser extension, the service and its data pipelines. TypeScript first, privacy by default.
Organisational psychology
Validation of the 3D Mind Model in practice, measurement frameworks that are ethically sound, review of the indicators, and advice on responsible deployment with HR.
Business development
Go-to-market among Swiss and European organisations, customer agreements, and partnerships with HR consultancies.
What you can expect
Ethics first
Privacy and the protection of employees come before growth. Every feature passes that review.
Honest about where we are
We are at the beginning: high ownership, open problems, and results we publish with their limits.
Small and cross-functional
Everyone ships. Psychologists, engineers and HR experts sit in the same conversation.
Swiss by choice
For the data protection law, the values, and because the people we build for are here.
Research meets product
Behavioural science, AI and product design, in one team.
A working system
Measured results and a working product, not a slide deck.

Write to us anyway. Tell us why you care about the problem, what you would bring, and what kind of role you look for.
