Founding Hardware Engineer

What you’ll do:

As founding hardware engineer, you will be a core contributor to our ultra-low latency matching engine, implementing its technology as a hw/sw co-design in SystemVerilog, Rust, and C++.

PAX ultra low-latency in-silicon matching engine:

PAX is building the world's first exchange and co-located trading facility on a chip. We will go-to-market using AWS F2 FPGA instances and follow-on with an ASIC design that combines network aggregation with exchange functionality.

PAX provides the fastest tick-to-trade and market data publication in the world, across all exchanges (e.g. faster than NYSE, Deutsche Börse, etc.).

Exchange integrated high frequency trading logic:

The PAX λ API provides traders with on-chip exchange integrated HFT decision logic. Using the λ API, traders can make markets or take arbitrage opportunities. The λ API enables traders to respond to market events the very instant the information is registered in the exchange matching engine.

PAX business model:

PAX sells access to its ultra-low latency λ API and offers trading otherwise for free. Existing exchanges typically offer rebates for liquidity providers ("makers") and charge fees to liquidity takers (the "maker/taker" fee structure). At PAX when λ and non-λ orders pair together, the free-tier order is given a cash rebate regardless of whether their order was characterized as making or taking. PAX is the first exchange to offer zero-fee trading and rebates for both making and taking.

Deep dives on PAX market structure & technology:

• On-exchange trading incentives with inherent price competition.

• PAX rebates & fees.

• PAX λ API.
