Qualcomm | Canada | Full Time | Remote(Canada)| QEMU

My team is looking to hire a software developer to help us design and extend QEMU support [1] for the Hexagon DSP [2]. We're looking for candidates who have experience coding in C, C++ or Rust* and who aren't afraid of rolling up their sleeves and poring over disassembled code. This particular architecture is a bit more challenging than most, because it's a bit unique. It's a VLIW [3], so it's a great opportunity to learn about an interesting architecture. Millions of Hexagon DSPs are out there, most are found in DragonWing/Snapdragon/DragonFly SoCs for Laptops, Android phones, cars and more!

We collaborate a lot with Open Source communities like QEMU, LLVM [4], the Linux kernel [5], and more. I love being able to work on Open Source software at my day job.

You can contact me directly (email addr is in my HN user link). If you don't have experience with QEMU - don't worry! Most of us didn't have any experience with it until recently, too.

The rest of the team you'd work with lives mostly in Canada, EU, US.

* Rust experience may serve the role well but we don’t (yet) have any product software in Rust.

We are well funded, have dedicated compute for large-scale training, and publish at top venues.

Small team of senior researchers and engineers. Default is 3 days a week in our Freiburg office; remote with regular visits is possible.

We're adding a few senior people in:

- Research: LLM pre-training, post-training, speech, vision-language models, model adaptation

- Engineering: inference and hardware optimization (C++/Rust, CUDA, SIMD, NPUs), data pipelines (text and multimodal), agentic platform

Research roles: typically a PhD plus several years of experience, or an equivalent track record. Engineering roles: several years of hands-on experience in the area.

Competitive salary plus equity, time to publish and present, flat hierarchy, excellent coffee. We share details on the company, team and backing in the first call.

Apply: jobs@albslabs.com with your CV and a link to work you're proud of (paper, code, blog). Put your area of interest in the subject line.

Devin (The Devin Experience) | Founding Hardware Lead | Toronto or Boston preferred | REMOTE (North American time zones) | Full-time | Competitive salary + meaningful founding equity | https://experiencedevin.com/jobs

We're building an intimate device that responds in real time to a live AI-generated story and to her body: an app-connected, sensor-equipped vibrator synced to an interactive audio story that AI performs live. The device follows the story, and the story follows her body. Our first 1,000 pre-orders sold out, and we've raised a $1.5M pre-seed. All-woman founding team (CEO is an exited founder and HBS grad; CTO is a multi-time founder and MIT alum; COO/CPO helped lead Wattpad to a $650M exit).

This is employee #1. You'll own hardware architecture, review and change our China partners' schematics and C/C++ BLE firmware (ESP32 / nRF), co-design the BLE protocol under tight latency budgets, integrate the IMU and body sensors (separating real body signals from the device's own vibration), and take us from prototype through EVT/DVT, certification and production, with trips to Shenzhen at key milestones.

You've shipped connected hardware end to end (consumer, wearable, medical or robotics), have 8+ years building hardware products with hands-on embedded work, and have been through at least one production ramp with a contract manufacturer. Bonus: haptics/motor control (ERM/LRA, PWM, waveform tuning), real-time systems, body-worn sensing, FCC/CE/Bluetooth SIG certification.

Apply: email seema@experiencedevin.com with your resume or LinkedIn and a short note on one product you shipped: what you owned, the hardest hardware problem you solved, and how you knew it worked.

Thunder Compute (YC S24) | C++ Systems, Infrastructure, BizOps | San Francisco (Onsite) | Full-time | https://www.thundercompute.com

We're building the VMware for GPUs. Most GPUs in the cloud sit idle a lot of the time because they're bolted to one machine over PCIe. We decouple them.

Our virtualization layer is a userspace shim, loaded through LD_PRELOAD, that intercepts CUDA calls and ships them over the network to a host with a physical GPU somewhere else in the data center. Workloads run unchanged. When a process goes idle, the GPU detaches and gets reassigned, and reattaches in tens of milliseconds when it's needed again. Think Ceph for GPUs: the GPU becomes a network resource a cluster-wide scheduler can pool and pack.

The hard part is making that fast. We're within ~10% of native on most AI workloads, and it lets us serve ~1.8x more users on the same fleet. We run it in production as our own GPU cloud and sell it to enterprises with underutilized fleets.

Team is from Citadel Securities, Aquatic, Old Mission, AWS, and Bain. Series A, $17.5M raised from Matrix and Y Combinator.

Open roles:

- Software Engineer, C++ Systems ($215K-$325K + meaningful equity). Low-level, latency-sensitive work on the virtualization layer. Quant dev / HFT background preferred: https://jobs.ashbyhq.com/thundercompute/2efae53b-817c-43e7-9...

- Software Engineer, Infrastructure ($150K-$250K + meaningful equity). Go, Kubernetes, reliable systems at scale: https://jobs.ashbyhq.com/thundercompute/927a922b-c607-4b0e-a...

- Business Operations Lead ($150K-$225K + meaningful equity): https://jobs.ashbyhq.com/thundercompute/4f28e418-b77b-446e-a...

If you're cracked at building systems software and want to do something more meaningful than creating liquidity, reach out.
