Quant Developer, Trading Systems (Rust and C++)

Blockhouse, full time, NYC in person or hybrid preferred, remote within US time zones considered

Blockhouse gives institutional asset managers access to the kind of trading infrastructure that usually takes years and millions of dollars to build. Founded in 2022, we run a noncustodial platform where clients keep custody of their assets while they trade, hedge and compound portfolios across crypto and tokenized markets, from FX and equities to treasuries and compute futures. Alongside the platform we run live delta neutral funding rate and market making strategies with client capital across major venues, and we keep expanding into new frontier markets such as compute hedging.

This is a quant engineering role at its core, sitting between research and production and owning the path from a researcher's spec to a live signal trading real capital. You'll work directly with the founders and our quant researchers, and although the role is open to engineers with 2 to 5 years of experience, we expect you to step up quickly, setting objectives, writing specs, breaking work into tickets and guiding the rest of the engineering team with your judgment.
