ABOUT RAVEN
Raven is a proprietary crypto market-making and high-frequency trading firm. We trade spot, perpetuals, and prediction markets with dedicated low-latency infrastructure across eight major trading regions.
We hire competitive individuals and natural problem solvers with a record of ranking at something hard, whether competitive programming, games, or mathematics, who treat an unfamiliar problem as a challenge rather than an obstacle. We can teach markets; we cannot teach drive.
We build our own stack end to end, from connectivity and pricing through execution, monitoring, and research data.
THE ROLE
Before a strategy can price anything, a packet has to arrive, be decoded, sequenced, book-built, normalized, timestamped, and delivered - in microseconds, correctly, around the clock, because markets never sleep. You own that path, and the capture, archive, and replay that give the same data a second life in research. A stale book or a silent gap loses money faster than almost any other bug we can write.
WHAT YOU'LL OWN
Feed handlers:
Ingestion from everything we price against. Centralized exchange venues over WebSocket, FIX, and proprietary binary protocols, plus the reference feeds around them, futures and FX included - sequencing, gap detection and recovery, reconnect logic that survives the ugliest exchange behavior. DeFi feeds from the blockchain nodes around the world, where block and log streams, mempool visibility, and AMM pool state have to be reconstructed into something quotable, and reorgs, chain-tip lag, and node health are yours. Prediction markets, where books sit over discrete outcomes and the event and resolution metadata is what makes them interpretable. Work through undocumented rate limits, ghost levels, out-of-order deltas.
Latency engineering: Hardware timestamps, NUMA- and cache-aware layout, kernel bypass where it pays for itself, tail latency as the number that matters.
Capture and replay: Line-rate capture into our full-d
