We trade the world's most volatile markets and make them more efficient.
Koton is a boutique, proprietary trading firm and a top-tier market maker on the world's largest crypto exchange, quoting across roughly 90% of trading pairs on both spot and futures. Our core is high-frequency market making, where the speed and cost-efficiency of execution decide the outcome. Around that core we run further strategies built on the same low-latency infrastructure. Binance is where our depth sits today, and we are actively expanding to other venues.
We build our own technology and run these strategies at scale, all with a small, tight-knit team where individual work is directly visible in the results. Most of our team sits in Brno in Czech Republic.
We're looking for a senior researcher to own trading strategies end-to-end, from first hypothesis to live PnL. The work comes with genuine autonomy, real capital behind it, and a feedback loop tight enough to tell you quickly whether your edge is real.
What you'll do
- Design and iterate crypto trading strategies
- Identify signals in order book dynamics, analyse trade flow, fill behavior and short-term price evolution
- State hypotheses, validate them on real historical data
- Design solutions, collaborate with dev team to deploy into production, analyze feedback from trading team
- Refine performance and PnL metrics, perform post-trade analysis and continuously review trading logic
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Who you are
- You have a detailed understanding of a number of trading strategies that were successful in a live HFT environment, either your own design or a long-term contribution to strategies design in a team
- You own the full loop: idea → analysis, validation → live PoC → iteration
- You communicate clearly and can explain your reasoning to various stakeholders
- You can work happily and efficiently in a remote setup long-term or you are happy to relocate
Bonus points
- Direct HFT experience in crypto and on exchanges (a real plus, though not required)
- Hands-on cross-exchange arbitrage
- Experience with DEX strategies and on-chain venues
- You think in terms of edge decay, latency sensitivity, and the trade-off between inventory risk and spread capture
- Expert Python, SQL, advanced.net
We expect strong evidence across several of these:
- A career across several trading firms including a research-focused role
- HFT or market making in crypto or traditional markets
- Proprietary trading firms or quantitative trading teams
- Order book mechanics
- Execution, slippage, and adverse selection
- Short-term alpha generation
- Cross exchange arbitrage
