About Nabla
We are a team of entrepreneurs, clinicians and engineers committed to bringing back joy to the practice of medicine.
Together with a community of clinician innovators, we've harnessed the best of machine learning science to develop Nabla: the leading AI assistant that's restoring the human connection at the heart of healthcare. By streamlining clinical documentation, Nabla is helping clinicians focus on matters most - patient care. Today, over 85,000 clinicians across 130+ healthcare organizations trust Nabla to support how they deliver care every day.
We're at the start of an ambitious journey: Ambient listening, dictation, coding, and command capabilities are all converging into a proactive assistant that intuitively streamlines clinical and financial workflows.
Backed by a recent $70M Series C, we're hiring to build the next generation of clinical AI and improve the lives of clinicians and patients everywhere.
This is a great time to join us!
The best of AI at the service of healthcare
Nabla's phenomenal traction is the result of 3 years of diligent product development.

Yann LeCun, Meta's Chief AI Scientist and Turing award winner, is an advisor to Nabla.

Together, we're committed to making clinicians' lives easier and improving healthcare experiences for everyone. We believe in a world where clinicians can focus on what they were trained to do - caring for their patients, and where no patient feels their visit was rushed.
We come to work excited to leverage AI to do more for clinicians. We're obsessed with our users' satisfaction and we actively seek out opportunities to engage one-on-one with clinicians to understand how Nabla can better help. We consistently look for ways to improve and do not shy away from doing the work to excel. Whether it's a feature our users asked for, or a new article for our blog, we prioritize collaboration to deliver exceptional outcomes.
We love having fun as much as we love work. Our #nablabla channel is as active as our #feature-show-off channel, we exercise during the work day at least 3 times a week (yoga, running, pilates, or HIIT, your choice!), enjoy regular off-sites to gather the team, and travel to see each other in places like NY, Paris, San Francisco, and many other vibrant cities. Oh, and we're constantly snacking on chocolate or nuts!
If this sounds like an environment you'll thrive in, we look forward to reading your application!
