BackEnd Engineer

Who we are

Symmio is redefining onchain derivatives, bringing the liquidity and trading experience of top centralized exchanges like Binance and Bybit to a fully decentralized environment—where users always retain control of their funds. As a pioneer in onchain bilateral OTC since 2021, Symmio powers a growing ecosystem of seven distribution partners, facilitating over $11 billion in trading volume with more than $140 million in available open interest capacity. With options and meme derivatives launching later this year, Symmio is at the forefront of the next evolutions in decentralized finance.

Role
We’re looking for a Backend Engineer who thrives on solving the impossible. This role is for someone eager to push the boundaries of decentralized finance by building pSymm, a new protocol that extends Symmio’s architecture to meet TradFi requirements, including privacy, post-trade settlement, and Oracle security. This is pivotal for Symmio's integration of FIX protocols, ETFs, stocks, private onchain fund management, micro-derivatives, interest rate derivatives (IRDs), and, eventually, cross-border settlement of real-world assets (RWAs).

Responsibilities
As an early member of the pSymm team, you’ll bootstrap pSymm the protocol and its dApps from scratch. You’ll work on first-of-their-kind applications, already backed by partners ready for distribution. This is an opportunity to build and scale groundbreaking infrastructure in decentralized finance—if successful, you'll grow alongside it.
