Attune is building developer tools for a post-AI world. Our first product is faster build tools that require zero migration effort. AI is enabling engineers to write code faster than ever. The next bottleneck will be all the other tooling between code and deployment. We’re looking for a Founding Software Engineer to help us build the future of software development: someone with the taste to see how the future of software development should look, and the autonomy and pragmatism to build that future. This is for you if - You care deeply about the craft of software engineering.

More 𝛼, less latency: exchange and HFT on one chip. As founding software engineer, you will be a core contributor to our ultra-low latency matching engine, implementing its technology as a hw/sw co-design in Rust. 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.). 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 sells access to its ultra-low latency λ API and offers trading otherwise for free. Existing exchanges typica
