Immunant | Systems Programmer | REMOTE (US only) | Full-time | $120k - $150k + retirement benefits

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.

To apply: team@immunant.com

We look forward to hearing from you!

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

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.

You can see a list of open positions on our career page: https://www.saildrone.com/careers
