EnsoData | healthcare, sleep, machine learning | Hybrid or Remote (Madison, WI) | Product Manager - Software Medical Devices SaaS | Full Time | $110k-$130k + bonus, stock options | https://apply.workable.com/ensodata/j/5fd6175feb/

Sleep is vital to recharging mentally, restoring our bodies physically, and fighting off disease. Sleep is so core to our health that it's the activity we all spend most of our life doing. Yet sleep disorders are some of the most underdiagnosed health conditions on the planet, with an estimated 80% of obstructive sleep apnea patients undiagnosed and untreated

EnsoData uses machine learning, integration with pulse oximeter hardware, mobile apps, and clinician review UIs to automate sleep study scoring and give sleep clinicians tools to find and help patients with sleep disorders.

We're hiring a product manager to uncover what features our customers crave most, conduct discovery research in the sleep industry, define and prioritize product requirements, partner with engineers to ship features, and work with marketers to tell compelling product stories. You'll manage the product development process from whiteboard mockups tested with real users through to detailed specs and launch, breaking down ambiguous problems into releasable slices that bring AI-powered sleep diagnosis to more patients.

ProPublica | Director of Product Engineering | Remote (US only) or NYC | Full-time

ProPublica is a non-profit newsroom that investigates abuses of trust in the public interest. Journalism we published last year shed light on the impact of DOGE and ICE, investigated right-wing militias, told stories about the US medical system, and more. Here were our most-read stories in 2025: https://www.propublica.org/article/propublica-most-read-stor...

I'm the Senior Director of Technology. I'm hiring a pragmatic, mission-driven Director of Product Engineering, who will report to me, in order to provide more support for our product engineers who work on our publishing and data products. (This is not a reporting position.) You'll directly lead and manage a small team of engineers and help us to create and maintain great engineering processes.

The expected salary range for this position is $170,000 to $180,000. We cannot sponsor visas and must hire in the US. The role is almost fully remote: we have two in-person week-long summits a year.

Komodo Health | AI Platform Engineer (Senior / Staff) | Full-Time | $200-$298k + equity... | SF/NY Once-a-month-few-days / Remote US. Can sponsor.

Healthcare in the U.S. is a mess. Komodo Health is fixing that—with data. We’ve mapped the patient journey across the country to build the most complete picture of disease burden and treatment gaps. Our customers are pharma, payers, and health systems who actually want to do something meaningful with that information.

We have an exciting product, marmot, that is AI-native, both in the interface as well as in development, and want to carefully grow high productivity teams around this offering. AI integrated with Komodo's data is giving some of the most unique, real world insights any of us has seen come out of the new LLM era. Our product was just featured on Times Sqaure too! https://www.linkedin.com/posts/komodo-health_marmot-sighting...

As part of marmot, we are building an enterprise-grade AI platform, and this build out needs smart individuals who will sit at the nexus of AI Agent architectures, complex data engineering, advanced data science and messy healthcare data.

You will be an ideal candidate if you have data engineering experience as well as some experience in platform engineering, in a startup environment. We don't just want to build pipelines, we want to build AI-assisted systems that can build customized pipelines for our deployments.

This will be a small, nimble team, and we are also experimenting with our work culture as AI disrupts every aspect of it. A hunger for trying out new ideas in every aspect of work would be appreciated!

Perks will include periodic travel to SF/NY for on-site, executive coaching, etc. For the right candidate, we can also consider other perks like a 4 day work-week.

If this post sounds exciting, please email me at Email is hidden.

Important notes before you email:

1. You need to already be in the US.

2. You really need to have experience with advanced data engineering. AI experience is optional, though we will likely have to test you for your aptitude in it.

3. I have mentioned a keyword in my HN profile, include the keyword in the email (there's a bunch of people who just send emails to every address in such hiring posts). I will read every email mentioning that keyword thats sent in the next two days!
