Careers at CallidusOS™
Build the operating system UK clinics deserve.
We're a small UK team building the platform private clinics actually want to use. If you like meaningful work, modern tools and grown-up colleagues, read on.
What it's like
Work that matters, with people you'll like.
Care, in the work
We're building software that touches patient care. Quality matters. We don't ship things we wouldn't trust with our own families.
Bias to ship
Decisions move at clinic speed, not committee speed. If you'd rather get something live and iterate than debate it for a quarter, you'll fit in.
Small team, big trust
We hire grown-ups and treat them like grown-ups. No micromanagement, no theatre, no busywork. Own your area and ship it.
Proximity to clinicians
You will spend time with real clinics. The best product decisions come from watching a busy front desk on a Saturday afternoon, not from a Notion doc.
The boring-but-important bits
How we work
Remote-friendly
Work from where you do your best work. We meet up in person regularly.
Real downtime

Make it yours
Own a meaningful slice of the product from day one. Your name will be on what you build.
