Freed | Software Engineers (Fullstack / AI), EM / Tech Lead Manager, UX Design | SF | https://getfreed.ai | Full-time

Doctors are overworked, burnt out, and are quitting in masses.

I'm head of engineering at Freed, where we combine clinician love with the latest AI tech and intense execution to create products that make clinicians happier.

Our first product is an AI scribe that automates medical documentation.

- Acquired 20,000 paying and loving clinicians, >$20M ARR in under two years

- Generate 70,000 patient notes daily using ASR and LLMs, and have saved clinicians 2.7 million hours

- Created a consumer-grade UX, with greater enthusiasm than any product I've seen (https://love.getfreed.ai/b2xGQ1)

If you’re excited about exploring new AI UX paradigms and making an impact that goes beyond design. Our team is small, kind, mission-driven — and deeply ambitious. We’re looking for someone who’s excited by ambiguity, energized by building, and who cares as much about pixels as they do about people.

Tufalabs | AI researchers and engineers | Zurich | Full time | Onsite | $165k | https://tufalabs.ai/

We are a small, independent research group working on fundamental AI research.

Since around 2008, I always believed that AI research will be the most impactful technology to work on, both from an intellectual curiosity and technological capability perspective. After a few failed attempts to get into ML/AI research, I decided to apply it to quant finance, and then start an AI research lab from it.

This is how Tufalabs was funded about a year ago. We started working on ARC (https://arcprize.org/arc-agi), and since o3 we focus on LLM-based reasoning, self-improving loops and scaling trends. You can see some of our research there: https://tufalabs.ai/blog/_site/

We do not have too many spots left, but I want to make sure we don't miss-out on people who would be great fits. We look for obsessive people who share the same research interests. To apply, email me at not_a_cat at fastmail com.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.
