We are a new discretionary, tech industry focused hedge fund, founded by a portfolio manager with 15+ years of experience at a Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at a well known Tiger Cub and briefly running a data startup.

We are hiring for: - Frontend senior/staff engineer for our internal research management web application - VP Eng, to lead data engineering + fullstack development (this is a player-coach role, with a lot of IC work expected; it is a small team)

Our tech stack: * Frontend: Typescript, Vue3 * Backend: Cloudflare, Supabase/Postgresql, Typescript *

On the data side: AWS, Cloudflare, Snowflake, Clickhouse, Dagster

Obviously, we are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).

We're in full-time in office in NYC, so that's a requirement for FTE.

We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.

I write about hedge fund data teams frequently here, if you are just interested in learning about the space: https://magis.substack.com/

Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)

Community Colleges are an effective and affordable part of lifting communities out of poverty through the power of education, vocational training, and cost-effective transfer credits. LBCC is looking for a Manager of Enterprise Systems and Applications Programming to lead a team in maintaining and improving our application and database environments using Oracle Cloud Infrastructure. Pay, benefits, and a full list of duties are listed on our website at the link above.

I’m going to be honest with you: I want to be the best in the world at what I do. I’m not there yet, but I know I am willing to put in the hours, and fail as many times as it takes for me to get there.

For that reason, Phrasing to me is more than just a language learning application. It’s a chance to do something different. A chance to build a product that pushes humanity forward. A chance to build experiences that are genuinely delightful. A chance to build a company that can inspire.

I’ve built the current version entirely myself (not even a single like of AI generated code). On the good side: the product is working, I’m using it every day to genuinely learn 18 languages, and the user base is growing. On the bad side: the onboarding flow needs a lot of work, the pipelines keep breaking, and the maintenance burden is too much for me to handle alone and make progress on the product at the same time.

I’m looking for an engineer to join in a co-founding capacity and help me build something truly great. You would assume responsibility of the backend Elixir application, while I spearhead the various frontends (web, mobile, design, marketing). You’d make sure every task succeeds, keep queries times minimal, and optimize the crap out of the data and the infra. On the product & leadership side—we would collaborate on everything. I believe strongly that the best ideas are born of two minds.

And to tie it all together, I’m looking for someone else that wants to be great. Someone who wants to do things differently, someone who isn’t afraid to chase their dream and take their shot.

No experience for this role is necessary. All I care about is that you’re competent, passionate and hungry.

If you feel like this is you, then send a well written introduction to hn [at] phrasing [dot] app. Any AI applications will be ignored and the senders blocked.
