Tandem Health | Senior/Staff 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. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)

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.

Doc Labs | Founding Full-Stack Engineer | San Francisco | REMOTE (US), San Francisco | Full-time | No Visa sponsorship

Enterprises are drowning in unstructured documents and outdated workflows; we see a massive opportunity to build the next big enterprise automation platform to transform how work gets done, starting with commercial construction.

Join now and be at the ground floor of a pre-seed startup with strong momentum already in place: signed design partners, a clear product north star, and product development underway. You’ll be building alongside a team of ex-Salesforce leaders/operators with prior exits and 0→1→Salesforce-scale experience.

What You’ll Do:

- Help architect, build, and ship our core platform.

- Collaborate directly with design partners to validate and iterate quickly.

- Influence product strategy, technical direction and architecture from day one.

Who You Are:

- We’re looking for someone who thrives in ambiguity, moves fast, and thinks boldly.

- You’ve shipped products for 3 years at least and yearn to continue learning everyday growing yourself, the product and the team.

Ideal background includes two or more of the following:

- Data, enterprise SaaS, or startup experience

- Full-stack engineering with equal comfort across both frontend + backend

- AI/ML expertise

Tech Stack:

- SvelteKit, Tailwind, DaisyUI, Postgres, and Supabase

- Fast API, Python, Neo4J, LanceDB, Cloud AI providers

If you’re excited to build, ship, and grow with us, let’s talk. To apply, email me: srini@doclabs.ai

Avy | Staff Engineer / Startup Polyglot Engineer | San Francisco | Onsite (Hybrid) | Full-Time | https://www.avy.app

We are an early-stage, well-funded startup making humans and computers work together more efficiently. Experienced team from Apple AIML and other great companies.

We're looking for a polyglot "startup engineer" at the Staff+ level can help with the end-to-end implementation of new features and capabilities and who can move between different components, be creative, be flexible, take ownership, and get things done. We have a complex, challenging product, but one that's amazing to work on and that will soon change how people think about working with each other and with AI.

You'll enjoy this role if:

- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- You are innovative, get satisfaction out of learning new things, and thrive in an environment of uncertainty and opportunity

To succeed, you should:

- Have the wisdom to know when to take the fast route vs when to step back and clean up your mess

- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration

- Be versed across many programming languages (e.g. from C++/Java/Swift to Go to JavaScript or Python)

- Have worked on many types of projects and software -- have you built servers, written games, shipped native apps, and vibe-coded (kidding) web apps? If so, you're a fit.

- Be versatile and work both high level and low level, on old tech and new. Have you both prompt-engineered an LLM AND tweaked the code that decodes tokens in your own local LLM runner? If so, you're a fit.

Property Meld | Senior Software Engineer | Full-time | Remote (US & Canada) or Rapid City, SD

Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?

Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

Stack: Python, Django, Typescript, React, React Native, PostgreSQL

Zoca | AI Engineer | Full-time | Bangalore (In-office)

I'm Shambhav, CTO & co-founder at Zoca. I'm building a team to push the boundaries of what's possible with AI.

So far, we've built a platform from Bangalore that has outperformed every competitor in our space — small businesses happily pay us 10x our competitors' price because our agents actually work. These agents work like real business partners, generate leads, do followups, book appointments, manage reviews and more. We're already powering growth for over a thousand businesses.

In the next 12 months, we're going to scale this to tens of thousands, while making the agents smarter, more reliable, and capable of things people think aren't possible today. We'll be working on technical challenges like multi-channel conversations, browser automation at scale, retrieval pipelines, and real-time monitoring/eval loops.

I need AI Engineers who want to build like founders — not paper over things in a research repo, but ship production systems that touch real users. Strong TS/Python skills, a builder's mindset, and a track record of actually building (agents, GSoC projects, or similar) is what I'm looking for.

If this excites you, send me an email at shambhav@zoca.com with your working demos or GitHub profile. Show me what you've hacked on.
