If you're interested in low-level, resource-constrained and privileged execution environments, consider joining our team of compiler, OS, and Rust enthusiasts.
At Immunant, we spend much time staring at weird build errors, ISA or ABI documentation, or digging through obscure build systems or C code written 20 years ago. In any case, we strive to make the systems we're working on more secure, more efficient, and have more Rust in them (whenever we get a chance).
We also maintain and enhance the fully open source c2rust translation framework.
If you have recent, professional experience with C/C++ and Rust and know about operating systems, hypervisor internals, or compilers, we'd love to hear from you. Candidates with only superficial knowledge in all of these areas are not encouraged to apply. Please note that we can only consider candidates resident in the US.
We offer a remote-friendly, collaborative work environment with a high degree of autonomy and competitive benefits.

We look forward to hearing from you!
Freeform is deploying metal 3D printing factories at global scale and setting a new frontier in manufacturing. With AI, GPUs, and FPGAs working in tandem, our system monitors and corrects every microsecond of the process, delivering a level of precision, speed, and quality that’s never been possible—until now. This isn’t just an improvement; it’s a leap forward in how complex metal parts are made, with the ability to revolutionize industries like aerospace, defense, automotive, energy, and beyond. We are backed by top VCs including NVIDIA’s NVentures, Founders Fund, and Threshold Ventures.
It’s a small, tight-knit team and you’d have the opportunity to own significant and impactful greenfield projects throughout the entire development lifecycle and much more. Our software team comes from the likes of Google, SpaceX, and Apple, and believe in taking a first principles approach to solving hard problems.

We make sure public money is well invested by building software for governments. We're doing to government software services what challenger banks did to banking.
Our clients are mainly governmental research institutions - we're building tools for scientists to process & visualise data, HPC data processing libraries, web apps to make people's working lives easier, and DevOps pipelines.
Currently hiring a senior python dev, a mid-level python dev, and a senior rust/c++ dev.
We do government work so the location requirement is strict. Save yourself some time and don't apply if you're outside the EU.
Company: We're a small scientific software development company that develops custom scientific and engineering analysis applications in domains including: space situational awareness (monitoring the locations, health and status of on-orbit satellites), image simulation, high power microwave systems, modeling and simulation, laser systems modeling, AI/ML including physics-informed neural networks (PINN), human body thermoregulation, computer vision and image processing, high performance computing (HPC), computer aided design (CAD), and more. All exciting applications and no CRUD. We emphasize high quality code and lightweight processes that free software engineers to be productive.
Experience: Other than interns, we currently require a Bachelors degree in physics, engineering, math, computer science, or a related field, plus preferably 3+ years of work experience or a Masters or PhD in lieu of work experience. (Roughly 30% of our staff have PhDs.)
Technologies: Mostly C++23, Qt 6.9, CMake, git, OpenGL, CUDA, Boost, Jenkins. Windows and Linux, msvc/gcc/clang/clangcl. AI/ML and other projects use Python, some use Java or Javascript/Typescript/React.

Saildrone is the world's leading collector of ocean related in situ data via uncrewed vehicle, above and below the sea surface. We work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, counting biomass to establish fishing quotas, or detecting and stopping illegal fishing and drug trafficking.
Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we recently completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just wrapped up a big demonstration for our partners in NATO[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand our planet.
Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.
In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.
