Oils (https://oils.pub/) | Language Engineer / Debugger of Other People’s Cursed Shell Programs / Writer | REMOTE (non-US) | 50 euros/hour
Oils is our upgrade path from bash to a better language and runtime.
We’ve been awarded a 4th grant from https://nlnet.nl, and our focus is to show that OSH can be the ONLY shell on a Unix system, which is hard
It looks like we will reach this goal! Other than me, there are 4 people working PART TIME on this, and we can use more help.
If you like hunting down difficult bugs, and are skilled at Unix and Python, this could be a good fit.
Most bugs are too hard for 1 person to fix by themselves, so communication is important. And writing good test cases is important.
We’re also paying people to do polished writing, since we'd like to spread the word
Starting from 131, we’re down to 41 disagreements between OSH and sh/ash/bash, when building ~1600 packages in Alpine Linux
https://op.oils.pub/aports-build/published.html
Anyone who's not “scared” of these bugs is probably a good fit, and you can do as much or as little as you like. This is also an opportunity to get deeper into the interpreter
Communication happens on Zulip, and we also have video meetings approximately every 2 weeks
I'll have a blog post explaining this work soon, but feel free to e-mail me if this (unusual) job matches your interests. Any questions are very welcome, and you can dip your toes in to see if it works for you
I wrote this page a few years ago to help people assess the fit: https://github.com/oils-for-unix/oils/wiki/Where-Contributor...
The job is remote-only, and we slightly prefer non-US contributors due to our funding
Tech stack: Python, Shell, perhaps C++

Avy | Staff Engineer / Startup Polyglot Engineer | San Francisco | Onsite (Hybrid) | Full-Time | https://www.avy.app
We are an early-stage, well-funded startup making humans and computers work together more efficiently. Experienced team from Apple AIML and other great companies.
We're looking for a polyglot "startup engineer" at the Staff+ level can help with the end-to-end implementation of new features and capabilities and who can move between different components, be creative, be flexible, take ownership, and get things done. We have a complex, challenging product, but one that's amazing to work on and that will soon change how people think about working with each other and with AI.
You'll enjoy this role if:
- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product
- You are innovative, get satisfaction out of learning new things, and thrive in an environment of uncertainty and opportunity
To succeed, you should:
- Have the wisdom to know when to take the fast route vs when to step back and clean up your mess
- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration
- Be versed across many programming languages (e.g. from C++/Java/Swift to Go to JavaScript or Python)
- Have worked on many types of projects and software -- have you built servers, written games, shipped native apps, and vibe-coded (kidding) web apps? If so, you're a fit.
- Be versatile and work both high level and low level, on old tech and new. Have you both prompt-engineered an LLM AND tweaked the code that decodes tokens in your own local LLM runner? If so, you're a fit.
