Lightning Labs is hiring! We’re looking to expand our team to build technology that'll bring Bitcoin to the next billion people.

New Hedge fund | Sr/Staff Frontend Engineer | On-site (NYC)

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.

We are hiring for a frontend senior/staff engineer for our internal research management web application.

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

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 are potentially open to exceptional contractors located remotely.

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.

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

This greatly improves the quality of care and is on its path to becoming the next standard-of-care.

Our software stack includes Python/Django, React/Typescript, Terraform, AWS, and many other standard tools. We're a small, but nimble software team that prioritizes rapid iteration and continuous feedback to evolve our product. As a biotech company, we inherently need to always work cross functionally.

Small boutique consulting | Javascript Developer (Vue experience strongly preferred) | Remote (US) (some est meetings) | part-time/flexible/1099 | ~$50/hr

Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses. This is a great opportunity for people who value flexibility, maybe SAHMs, new parents, etc. who want to get back into the workforce in a very flexible way. Not a great fit for someone between who wants to do something temporary between jobs, supplemental around their existing full time job or who need a stable level of income.

The work is very different by client but not terribly difficult. However, no matter how senior you are there is a pretty low ceiling on what our clients are willing to pay. Our technology stack is anchored in: - JavaScript/Node/Vue - GCP/App Engine/Cloud Functions - Jira/Confluence/Google Workspace

If this sounds interesting and a good fit your lifestyle, reach out to [the two letter acronym for this Email is hidden

PS. Each time I post here I get 3-500 emails, almost all are low effort that don't meet the above description, I've hired 3 people from past posts, but it can take some time dig through everyone.
