Ethena Labs is building the first crypto-based reward-accruing synthetic dollar protocol. Arthur Hayes is a founding advisor and the team has deep experience across traditional finance and crypto engineering from firms such as Cerberus, Wintermute, BITMEX, Flow Traders, Deribit, Paradigm, GMX, Zircuit, Chainlink and Kaiko. We are backed by every major exchange and trading entity in the space.
We are building two interlinked products: a crypto-native synthetic dollar (USDe) and an Internet Bond (sUSDe) accruing rewards via a delta-neutral derivatives portfolio.
We believe creating a synthetic dollar which is not reliant on existing banking infrastructure is the single most important problem to solve and the largest opportunity in crypto today.
USDe will form the first part of a broader ecosystem of products we are building including fixed and floating rate Internet bonds and composable repo markets.
Join us!
This role must reside outside of the USA.
Ethena has quickly established itself as the fastest growing and most innovative financial product utilising digital asset technology to date. The Head of Trading Technology will own the entire trading technology stack, responsible for the overall strategy, development, and maintenance of Ethena’s trading platform. Which sits at the heart of, and powers, its flagship products: USDe & sUSD.
The role reports directly into the CTO, and includes leading a small team of trading technology engineers, collaborating with stakeholders in Trading, Risk and Ops teams. This role demands a hands-on leader with deep understanding of building trading systems. You’ll both guide your team and take a lead role in development.
Our focus is on high-quality engineering, resilient system design, development-velocity, and delivering best-in-class execution capabilities.
$250,000 - $300,000 a year
If you subscribe to the mission of separating the dollar from the state, then we want to hear from you!
We look forward to receiving your application and will be in touch after having a chance to review.
