Basis  Sweat-Equity

We are three operators. We are adding two — one who builds the systems, one who builds the signals.

Both are founding. Both matter from day one. The trial is real, the equity is real, the market is running whether you're on the desk or not.

The one who builds it.

Modern Systems Engineer  ·  Founding

You think in systems. Code architecture, AI workflows, deployment pipelines — you build things that hold under pressure and scale as models multiply.

Quant finance may be new territory. That's fine. Curiosity beats credentials here — you've broken things that didn't scale, and built things that did. The rest is domain.

Field notes
  • a.Design the research → deployment pipeline.
  • b.Own AI/ML workflow infrastructure end-to-end.
  • c.Keep live execution alive at 3am.
  • d.Break things that don't scale; build things that do.

Halfplane · South

The one who runs it.

Quant Researcher & Trader  ·  Founding
Field notes
  • a.Research signals with short half-lives.
  • b.Run models live as they get deployed.
  • c.Kill what breaks; ship what holds.
  • d.Watch models behave in real markets, not backtests.

You work at the intersection of R&D and live execution — building models, running them live as they deploy, iterating with the core team.

Deep mentorship. Real pipelines from day one. We train hard, you execute harder. Empirical instinct beats a résumé — bring a thesis, a notebook, a track record.

How we hire

No cover letters.
Show the work.

Three steps. No theatre, no funnel, no committee. We read what you send, we sit with you, we build together.

01 Submit
Send the work
A GitHub repo, a project, a model, a trade thesis. Something you built, not a résumé. We read every submission.
02 Conversation
Sit with us
A working session with the founders. We talk through what you've done and what you'd want to build here. No panel interviews.
03 Trial
Build together
Two-month sweat-equity trial, milestones set together. Hit them and you're on the team — stipend, ESOP, founding seat.
