Solace Health | Full-Stack | Remote (US Only)

I realize it's hard to tell these days what jobs are "real" but make no mistake - we're hiring aggressively.

About Solace:

The U.S. healthcare system wasn’t built for patients. It’s massive, confusing, exhausting, and designed to wear people down. It denies access, withholds clarity, fails to take patients seriously, and rarely shows them how to fix what’s broken.

At Solace, we’re on a mission to empower patients & improve outcomes.

By helping people work with professional health advocates, Solace serves as an integral, personal support layer for health issues in a way that the health system can’t. Using proprietary technology to match patients with experienced advocates, Solace cuts through the red tape of healthcare and helps individuals and families make informed decisions that result in better outcomes.

We're a Series B startup founded in 2022 and backed by Inspired Capital, Craft Ventures, Torch Capital, Menlo Ventures and Signalfire. We have a lean, fully-remote U.S. team distributed coast-to-coast.

Check out our funding announcement in the WSJ here: https://www.wsj.com/articles/medicare-coverage-fuels-solaces...

ko-br | Hiring across design, engineering, research and business development | https://ko-br.com | Onsite (London, UK or Cairo, Egypt)

It’s a shame that we have unbelievably good hardware like collaborative robots (cobots) that could transform warehouses and yet they still struggle with basic tasks like unloading mixed pallets. Why? Because today's software can't handle real-world chaos.

That's where we come in. At ko-br, we're building the AI brains that make robots truly adaptable. Our physical AI models tackle messy, unstructured problems starting with depalletizing of mixed boxes in dynamic warehouses. Think real-time adaptation to shifting pallets, mixed SKUs, and unexpected failures.

We're a deep tech startup at the crossroads of AI, robotics, and human-machine interaction. While warehouses are our first battlefield, our core mission is physical AI. So you need to be comfortable with the idea of pivoting to other sectors like education (ex: building robots for schools and universities).

P.S. We'll be in SF USA this fall, say hi if you're around :)

At Continua (http://continua.ai/), we've built an AI agent that users can invite into group conversations to make planning, coordination, and information retrieval effortless, and we're expanding our team. We've seen rapid growth over the last few months and want you to help us scale to the next level. Try adding our agent at http://continua.ai/ to group texts and kick the tires!

I’m David (https://www.linkedin.com/in/dpetrou/), the founder and CEO. Before starting Continua, I was a Distinguished Software Engineer at Google. We’re backed by top-tier VCs and incredible angel investors. Our team is a fantastic bunch (http://continua.ai/team) of accomplished engineers and researchers from Google, Slack, Disney, and several AI startups. We're pretty clued in on the technology side and have a strong vision of how the transformative technology of the last few years along with our own secret sauce (not just a ChatGPT wrapper) can help a huge number of people.

We’re hiring for two positions:

Senior/Staff Machine Learning Engineer (NYC or Seattle): https://jobs.ashbyhq.com/continua/f1d8fc3e-7092-486b-95c2-06... You'll work on building and improving the best LLM group chat experience there is, including fine-tuning models to boost conversational quality and improve scalability and identifying novel ways to build a "memory" which leads to a personalized and unique experience for our users. You're an experienced machine learning engineer with broad knowledge and skills and have experience fine-tuning LLMs for both generative and discriminative use cases. You have a Master's or PhD in Machine Learning (or a Bachelor’s with exceptional industry experience). You understand what it means to work at a fast-moving startup.

Product & Growth Manager (NYC): https://jobs.ashbyhq.com/continua/c3bc02c4-9663-4d69-8731-89... You're a technically minded PM that will drive go-to-market execution, user research, and feature development. You’ll run fast experiments, talk to users daily, and help us build the product roadmap based on real-world feedback and data. Ideal candidates have strong startup instincts, a technical background, and experience launching or growing AI products.

We offer competitive salary and equity, health benefits, 401k, and the opportunity to help shape the future of AI agents during one of the most exciting moments in computing history! Come build with us: https://jobs.ashbyhq.com/continua/

Yardstik | https://www.yardstik.com/ | Staff Engineer | Minneapolis or San Francisco (remote possible)

Yardstik is on a mission to reduce workforce risk through tools like background checks, identity verification, fraud monitoring and more. We are a well capitalized fast growing company based in Minneapolis but with a distributed workforce.

We’re looking for a Staff Engineer to help us build a brand new line of Risk products.

This isn’t just a heads-down coding role. You’d be leading the technical direction for an entirely new product category — shaping the architecture, making key system decisions, and working closely with Product and Go-To-Market to bring it all to life.

We’re a Ruby on Rails shop, so if you’ve got deep experience with Rails (and opinions on how to scale it well), you’ll feel right at home. You’ll have a ton of ownership, real input into the roadmap, and the chance to build something from the ground up that truly helps our customers reduce risk in smarter ways.

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?
