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 already have >500 organizations using our product.

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 just raised a $50M Series A and are now 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 scaling rapidly in terms of # of users and are especially keen to talk to seasoned backend, data and infrastructure engineers.

Even if we don’t have a role out for 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.

Unto Labs | Systems Engineer | San Francisco, CA | ONSITE (Hybrid OK), REMOTE (US) | Full-Time | https://jobs.ashbyhq.com/unto-labs/13df6bea-b253-4c80-ae05-5...

We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers. Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. Components are developed in C for maximal control over performance and resource usage.

Interesting problems you’ll tackle:

- Building and testing high-performance subsystems in C (cryptographic routines, consensus primitives, networking protocols)

- Designing robust process isolation on modern CPU architectures and tile-based multi-core layouts

- Optimizing memory hierarchies, cache utilization, and low-level I/O for commodity servers

You:

- 5+ years of systems programming in C/C++, Rust, or similar

- Deep expertise in CPU microarchitecture, memory subsystems, and low-level performance tuning

- Strong understanding of distributed systems design and consensus protocols

- Experience with high-performance networking and protocol design in real-time environments

Autokroma.com | C / ffmpeg / codecs / GPU / AI dev workflows | Full-time | HYBRID | Porto / North of Portugal

We do audio video software : video editing plugins, web panels, GPU visual effects, encoders, decoders, AI assisted development & testing. All levels are welcome but be sure to make me understand what are your current capabilities. You will work close to the code, user requests, whole UX in general, I try to minimize the layers between developers, products and final users.

If any of those topics are of interest to you, and you're around Porto to meet me : send me an email, the first part of the email is "contact" and after @ the domain name. Tell me your story, what you're looking for in your life now, a previous bad work experience you'd like to avoid and a good work experience that inspires you for the future.

AWS | Embedded Firmware Engineer | Austin, TX or Cupertino, CA | Full-time

I'm a team lead engineer at Annapurna Labs, the small company-within-a-company that designs AWS custom silicon. My organization designs and runs the Trainium and Inferentia machine learning (ML) accelerators. Our team is hiring engineers to help build the on-chip firmware stack for new and existing chips. This firmware is the lowest layer of the Neuron software stack; you can think of it as implementing a silicon-accelerated virtual machine that the Neuron compiler targets.

This is a bare metal, system software-oriented role (think C/C++); no specific ML experience is needed, but if you have experience writing GPU/CUDA kernels or microcode for other systems, we can definitely put your experience to work. If you're interested in machine learning, you'll be adjacent to people who have tons of experience with high performance compute, chip design, and ML algorithms.

We offer relocation to Austin or Cupertino; the team is split evenly between the two sites.

Ping me if you're wanting to chat about the team or the role: ghilliar -at- amazon.com. I'm an embedded systems engineer and I don't bite :)
