MaFi Games | Senior SWE/Game dev | Contract preferred | Remote | C#

Hi, I’m the co-founder of MaFi Games, an indie studio behind the game Captain of Industry. We’re a small but passionate team building the best factory simulation game we can, and we need more hands!

We’re looking for an experienced software engineer to join our team and help us speed up the development. While experience in game dev is a plus, what matters to us most is strong technical ability and computer science fundamentals, e.g. experience with technically demanding programs, 3D graphics, simulation, or performance optimization.

Some reasons you may enjoy working with us:

* A multicultural, collaborative, and innovative work environment where your voice is heard.

* Fully remote work with flexible working hours and vacation schedule.

* Long-term, full-time collaboration (not a fixed-term contract).

* A high-quality C# codebase, code reviews, tests.

* Interesting technical challenges and a lot of ownership over your work.

* Work with a talented team on a popular video game with a wonderful community.

For an example of some of our technical work see https://www.captain-of-industry.com/post/cd-31. We’ve also built a unique signal-free train system https://www.captain-of-industry.com/post/cd-46.

If you’re interested, you can find detailed information, requirements, and application instructions here: https://coigame.com/jobs-swe-hn

Thanks!

P.S. We’re also looking for 2D and 3D game asset artists, in case you know someone.

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.

Albs | Freiburg, Germany | ONSITE or HYBRID | Full-time | Member of Technical Staff (Senior / Staff)

Albs is an AI research lab in stealth, building real-time multimodal models (text, speech, vision) that run on-device. We treat model architecture, inference and runtime as one system, so our models hit tight budgets for latency, power and hardware cost. 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.

Veo Technologies | Senior Software Engineer (Rust, Python, C, Embedded Linux) | Copenhagen, Denmark | ONSITE | Full-time

You won't be writing drivers or doing low-level hardware work. Day to day that means Yocto system services, D-Bus and device trees, BLE/Wi-Fi with GATT and Protobuf protocols to our mobile apps, cloud integrations (REST, S3, OpenTelemetry), and diagnostics across a fleet of devices. You will work closely with our AI, video and cloud teams.

Stack: Rust, Python, C, Yocto/OpenEmbedded (meta-tegra), Zephyr, NixOS, GitHub Actions, AWS S3, OpenTelemetry, Grafana, Loggly.
