Flourish Health | Senior Software Engineer | Remote (US) | Full-time | https://flourish.health | $150-189k

We're helping teens and families get the mental health support they deserve. Many of our families are on Medicaid and/or in foster care. We build tech that powers care in the real world - apps for our staff (guides, therapist, psychiatrists, ops) and for the families we serve. We're mission-driven, moving fast, and grounded in the belief that thoughtful software can genuinely change lives.

We're hiring two senior engineers to help us level up as we begin scaling. You’d be joining a tight-knit group of builders: four engineers, our head of product, and me (Josh, co-founder/CTO). You’ll work full-stack to ship features, shape the system architecture, improve developer experience, and drive our product forward. You'll also get to help us ethically integrate more AI into our app to better support our patients.

Tech stack - Typescript/NodeJS | React Native (+RN Web) | MongoDB | Google Cloud

We're fully remote, mostly in the midwest for the dev team, great health insurance, 401k matching, 20 days PTO/9 sick.

If you're interested, email josh at hour website, mention HN, and send me a link/description of something you've built (GitHub, app, side project, blog, etc.)

Make an Impact on Climate! Looking for Data Stores and Full-Stack Engineers (Remote, US)

At Insight M, we combine innovative aerospace systems with advanced data science. Unlike traditional aerospace companies, we sell information, not hardware - we operate our sensors cost-effectively at a continental scale to produce novel data streams about pressing global problems.

First on our list: spotting hard-to-monitor emissions of methane, a potent greenhouse gas that accelerates climate change. Since starting continuous survey operations in 2018, Insight M has removed methane emissions equal to over 250 million tonnes of CO2e through our work. To put that in perspective, that’s equivalent to over 60 million cars being removed from the roads or shutting down about one hundred and sixty 350 MW coal-fired power plants for a year. That's like planting 4.2 billion urban trees and letting them grow for 10 years.

We call that a good start.

As a team, we love science and engineering, we love getting our hands dirty with hardware and software, and we love seeing our work make a difference in the real world.

We’ve created a diverse, collaborative, supportive, and fun environment based on integrity and treating people right. So no matter your sex, gender, sexual identity, gender identity, race, age, beliefs, sexual orientation, or disabilities, we welcome you and would like to work with you. :-)

It’s never boring, it’s always challenging, and we’re usually laughing.

A note of encouragement: If you don't meet 100% of the qualifications on our open job descriptions: https://jobs.lever.co/insightm, you should still seriously consider applying.

Individuals with a disability are encouraged to contact [Email is hidden] to request assistance with your application and accommodations in advance of your interview.
