Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.
What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.
You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

Paradromics is building a high bandwidth brain-machine interface for clinical use. The implant we built is restoring function to patients by streaming out neural data from specific brain regions in real time, which we convert to e.g. speech using machine learning. Check out our recent article in the NYT: https://archive.ph/C6CRb .
We're looking for help in further developing and hardening our embedded Linux components, which work in tandem with FPGAs and our custom ASICs to read out neural data. Some of the ongoing efforts are: HIL testing on real devices, integrating new sensor ASICs, maintaining our Yocto build system, exploratory work on prototypes, improving our clinical UX, and improving the core code that receives and massages data. The code is largely written in Rust with a little Typescript, (and bash, and bitbake recipes, etc).
You'll be expected to have experience constructing reliable and understandable software in Linux, and some level of experience in building and interacting with embedded hardware. Rust experience is ideal but not necessary. We're not looking for a specific number of YoE, but for motivated and hungry engineers who want to push the frontier of brain-machine interfaces.

Ethan here, founder of Jump.
Machine shops lose jobs because quoting is slow. A part comes in, someone has to read the drawing, figure out how to make it, and price it, and that can take hours. Many shops also can't put customer drawings in the cloud (ITAR, export control, or just customers who say no).
We're building Jump Quote: AI that reads a shop's drawings and drafts quotes in minutes, running on the shop's own computer. We're starting with a small group of founding CNC shops. Long term, we want anyone to be able to make anything, anywhere.
We're hiring founding engineers first (software/AI and manufacturing), but every role is open. If you're exceptional at something a startup needs, apply.
We care about kindness, honesty, ambition and intelligence. We don't care where you went to school or who you've worked for. We care that you have a winning mindset and can learn and ship fast.
How it works: we start now, remote within the US. In January 2027 we're together in person in Miami, and that's when the $140K–$160K + equity package starts. You need to be authorized to work in the US for at least the next 3 years; we can't sponsor visas.
