Phrasing is the best way to learn and maintain multiple languages [1]. With support for over 120 languages, science-based methodologies, and a beautiful custom built UI, Phrasing make’s it easier than ever to learn a language… or 10.
Phrasing is built with Elixir on the backend (lots of Broadway, FLAME, Nx and Scholar) with a ClojureScript front end. Everything is stored in a single Postgres database hosted with neon. I’m moving some code to a commons library, with the end goal of using Clojure as an isomorphic solution to run the same code on web, server, and mobile (<1% of the codebase, just the critical logic). The front-end is moving from Reagent+React to HSX+Preact+Preact Signals, although that’s going to be a long and slow migration.
Phrasing is my attempt to do something different [2], from both a product and a business perspective. No investments, no hyper scaling, no growth hacking — just tripling down on building the most effective application to learn a language.
Phrasing is launched, live, has some DAUs and MRR. However, long ago I’ve reached the limit of what one developer can do. I’m looking for someone to
- come on board and take over the entire Elixir codebase - watch the Broadway Pipelines, and not sleep if there are any failing checkpoints - optimize request times, reduce database pressure, and speed up extraction times - work with me to restructure things to reduce costs/complexity - work towards training novel embedding spaces, custom classic ML/NLP models, and long term algorithmic improvements to the SRS [3] - see this as a fun challenge, and have enough ownership of the product that I can focus on some user facing developments [4] Please note, I’m not looking to hire an engineer to work a 9-5, and I am in no hurry to hire someone soon. I’m looking for a co-founder to come on board, take ownership and accelerate the product. The product is built, working, and growing organically. While there is some MRR, the position will be rev-share & equity focused until the business produces enough for full salaries.To apply, please send an introduction hn at phrasing dot app. I will not be interviewing until the 12th of September, and no priority will be given to earlier or later applicants, so there is no rush. A sincere, well-written introduction is your best way to get an interview. No experience is required for this role, so long as you’re competent and hungry.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.
Looking for:
1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.
2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)
3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.
We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.
Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.
(If you have applied before, no need to re-apply, we’ll reach out.)

- Modelling buildings in code and finding the right UI for operators to edit them
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations and we need experienced, generalist engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
Nebula is building a modular blockchain stack to make on-chain finance faster, fairer, and more efficient than off-chain. The stack has 3 parts:
1. Execution environment – combines Rust + Sovereign SDK for highly performant, expressive private apps (e.g. solving latency asymmetry in exchanges). 2. Privacy protocol – blends cryptography + privacy hardware for verifiable, fast programmable privacy. 3. Nebula Exchange – a hyper-performant exchange using batch auctions + private orders to eliminate latency asymmetry and guarantee best prices. We’re hiring ambitious engineers to join the core team:
- Frontend (React/TS/Next.js) – focus on architecture, design systems, interactivity, realtime apps, Figma → production.
- Backend (Rust/Go) – core infra + SDK integration.
Requirements: detail-obsessed, independent problem solver, thrives in chaos, good communicator, can work ET hours. Nice to have: exp. in financial exchanges, realtime data-heavy apps, web3. Note: workload can be intense (sometimes 80+ hrs/wk).
