This role is responsible for leading our data pipelines development. SalesJack operates data ETLs from sources like client ERPs (enterprise resource platforms) and municipality open data to power our CRM features. You will collaborate directly with founders and lead engineers at the company and help:
- Enable scalability in our pipelines as we onboard more customers and data sources
- Setup visibility, monitoring and alerting in all parts of our ETL processes
- Allow plugging in AI led transformations at the right stages of our pipelines, and enable this to be done easily
- Lead RnD effort for AI toolings that transform a lot of manual work in the industry

- Someone who loves experimenting with data, regularly tries out new tools, and enjoys exploring the possibilities of AI and machine learning—especially large language models (LLMs)—we want to hear from you.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs, and our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are official participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS or AI company, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

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++

Tandem Health | Senior/Staff Software Engineers | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)
We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)
Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

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.
