Ostium is on a simple mission: make it possible for anyone with a digital wallet to trade stocks, commodities, currencies, and crypto with full transparency. No brokers, no freezes, no hidden spreads. We’re replacing the opaque, offshore brokerage model with a transparent, permissionless trading stack built onchain. Every trade, deposit, and withdrawal is verifiable through open, auditable code. We’ve raised $27.9M+ from General Catalyst, Jump, LocalGlobe, Susquehanna (SIG), GSR, Alliance DAO, Soma Capital, Balaji Srinivasan, Meltem Demirors, and others.
About the Role.
Every hire so far has been run by the founding team. You're our first in-house talent hire. You'll own the machine that keeps hiring moving, working directly with our Strategic Initiatives Lead and COO.
The breadth is the point. At a fund, a coordinator supports one desk. Here you'll help hire quants, engineers, and controllers, and also operators, marketers, creatives, and counsel. The full cycle, across every function, from first touch to signed offer.
Do this well and the path is obvious: grow to lead our recruiting function alongside the founding team.
What You'll Do.
Run the hiring machine
Own scheduling end to end: screens, technical rounds, onsites, debriefs
Keep Ashby clean: pipelines, feedback, and data people can trust
Chase interviewer feedback so no candidate sits in limbo
Draft offers and run pre-onboarding so new hires land ready on day one
Own the candidate experience
You're the first impression of Ostium: fast responses, sharp logistics, every detail right

Build the function
Turn what works into process: structured loops, scorecards, templates
Track hiring data from day one; data drives every decision here, recruiting included
How we recruit is yours to shape

A clear, fast communicator with candidates, founders, and external partners
High ownership: you spot the ball dropping and catch it before anyone asks
Comfortable when priorities shift; you re-sort and keep moving
You use AI tools to move faster
