CareIgnition | Senior Software Engineer (Generalist) | REMOTE, Chicago (US Only)

Medical billing in America is a black box of fragmented data and inefficiency. At CareIgnition, we are building the transparency layer for healthcare. We transform massive, messy datasets into financial clarity for employers and providers.

We are looking for a pragmatic generalist. You’ll be working across the entire stack: from building customer-facing features in React and Django to architecting data pipelines that process petabytes of medical claims and rates. Crucially, this role involves deep algorithmic and analytical work. You won't just move data; you will implement the logic that makes sense of it.

We value "generalist" DNA—engineers who are as comfortable optimizing a SQL query as they are building a clean UI component. If you enjoy solving high-scale data problems that have a direct impact on healthcare affordability, we’d love to talk.

Tech: Python, Django, React, AWS (ECS, Step Functions, Athena), SQL (DuckDB/Polars), Iceberg/Redshift.

If interested, reach to me at vikram.chauhan [at] careignition.com

Stealth | Software/AI Engineer | Remote Anywhere | Full Time

Hello, I am bootstrapping an AI companion startup. I believe that within 10 years, more people will date AI than humans. I think this is neither good nor bad, just interesting, and I want to build something in this space.

I am looking to hire someone with strong technical and problem solving skills. You will be seeing a lot of problems for the first time and need to just figure out how to hack a solution. Sometimes that involves writing code but not always. It is ok if you don't have prior AI experience.

Interesting problems we will work on:

- extreme latency issues while providing a fully multimodal experience (audio, video, text)

- building models that predict when to interrupt in a conversation

- building models and control systems for emotion

- generating avatar response in real time

- custom 3d models from input image

- real time or very fast video generation with custom characters

- llm memory

As I am bootstrapping this, I can only offer up to $4,000/mo ($50,000/yr) at the moment. If you are interested, please email James at gcyiuqy1 [at] gmail.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.

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.

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.

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 ramraj.velmurugan@komodohealth.com.

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!
