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 first 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.

We’re expanding our Stockholm team with exceptional engineers in a wide range of roles, from security to product.

Quantum Rise | Chicago or NYC (preferred), Remote for the right candidate | Full-time | No visa sponsorship | https://www.quantumrise.com/

Quantum Rise is an AI-forward consulting startup serving the middle market, across multiple industries. Clearly many companies are struggling to understand how to leverage artificial intelligence in their day-to-day operations, to understand what their existing workforce now needs to know, or to understand whether they're about to be disrupted. Many have business problems which "traditional" machine learning could help with even before the current GenAI hype cycle, but for whatever reason hadn't prioritized doing so until now. We try and help getting a handle around these issues and designing outcome-driven solutions.

Agentic AI Solutions Manager: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply curious about agentic systems across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners. This is a front-facing development role for someone who loves both tech and tackling real business problems. To apply, send me an email at julian.berman at quantumrise.com, mentioning HN and including your CV.

Data Engineer: You'll work directly with clients and application developers to design and build data solutions for AI-enabled applications, Lakehouses, Warehouses, and analytics that solve industry-specific problems. We're looking for someone passionate about delivering outcomes that combine best practices for deterministic data management and governance with AI functionality across tools, vendors, and platforms. Our clients need to leverage AI to solve specific problems using data. This is a client-facing development role for someone who loves to work with data technologies and tackle real business issues through genuine innovation. To apply, send John an email at john.swift at quantumrise.com, mentioning DE and including your resume/CV.

I’m exploring a new venture at the intersection of content provenance, fingerprinting, and AI usage attribution (audio initially, potentially expanding to voice, animation, and other media). The problem we’re evaluating is how to reliably attribute creative works when they are used, transformed, or learned by AI systems not enforcement or takedowns, but provable attribution and auditability that could later support licensing or royalties. Before building anything, we want to have a deep technical conversation with someone who has hands-on experience in areas like: • Audio or media fingerprinting / perceptual hashing • Robust similarity detection under transformations (compression, pitch/tempo changes, partial usage, synthesis) • Watermarking vs fingerprinting tradeoffs • False positives / false negatives in real-world systems • What is actually feasible vs academic or marketing claims This is not a job post (yet). We’re looking for paid consulting or advisory conversations to sanity-check an MVP approach before we pitch a pilot to talent agencies or studios. If you’ve worked on fingerprinting systems (music, video, speech, ML training detection, etc.) and are open to a conversation, I’d love to hear from you feel free to email me @ dmschultz1964@gmail.com Thanks in advance.

Full-Stack Engineer in Co-Founding for AI-driven pairing engine that automatically extracts menu data to create personalized coffee-pastry experiences.

*2. The Problem (Why now?)* Specialty coffee shops struggle to increase their average order value (AOV) because they lack digital tools to suggest pairings. Currently, menu data is "trapped" in PDFs, static websites, or Instagram images. Manually entering this data into a system is a bottleneck that prevents scaling.

*3. The Solution (How it works)* We build a bridge between B2B inventory and B2C taste. Our platform uses:

- *Automated Crawling:* Pulls data from shop URLs/socials. - *Computer Vision/NLP:* Standardizes messy menu items into a structured pairing-ready format. - *The Engine:* A hybrid ML/Rule-based system that suggests the perfect pastry for every bean profile.

*4. My Background (The Non-Tech Value)*

- *Domain Expertise:* Deep understanding of the specialty coffee B2B landscape. - *Customer Validation:* (Mention if you have spoken to X shops or have a waitlist). - *Execution:* I handle sales, marketing, and the B2B dashboard logic. I need a partner to own the data extraction and recommendation pipeline.

*5. What I’m looking for in a Co-Founder* A *Full Stack Engineer* who is excited by:

- Web scraping at scale. - OCR and NLP pipelines (turning images of menus into data). - Building "scrappy" MVPs that solve real problems for small businesses. - Ideally, a fellow runner or coffee lover who values high-intensity work and clear communication.
