Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure.

Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US) We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: [email protected].

We’re a small but mighty team made up of builders who love learning, being challenged, and changing the world. If that kind of job appeals to you, we should talk.

We’re looking for a Full-Stack Engineer to work across Oboe’s technology stack, from our backend pipelines that leverage AI to generate world-class content, all the way to the interfaces that our users use to engage with that content on the web.

We’re a team of generalists, so this job will have you learning every part of the systems and features that bring Oboe to life. This is a highly hands-on role where you’ll have tremendous impact, ship real features to real users, iterate quickly, and learn a ton.
