About Decibel:
Decibel is an exchange where equities, real world assets, commodities, indices and crypto trade around the clock, weekends included, all from one margin account. Matching, margin and liquidation happen onchain, so a trader can check our numbers instead of taking our word for them.

We launched in February 2026 and crossed $5B in cumulative volume in July. We are not building only for crypto natives. We are building for people who already trade equities and commodities and have never touched a wallet, and for anyone who wants access to more financial products, in more hours, than their current venue offers.

The team is small, scrappy and ambitious, and it runs financial infrastructure that does not close. Markets are open 24/7/365 and so is the venue, which means the team operates the same way: someone is always awake, releases go out on the day they are ready rather than on a Thursday, and the person who finds a problem is usually the person who chases it down.

About the role:
You will build product on top of the Decibel exchange, in our core monorepo,



mostly in the web app and the packages around it. Trading UI, onboarding flows, dashboards, internal tools, partner surfaces, and whatever the product needs next. The loop is short. You will regularly take something from idea to production in days rather than weeks.

The reason this role asks for Rust is not that you will be writing the matching engine. It is that our trading API and indexer are written in Rust, and the difference between an engineer who can read them and one who cannot is the difference between shipping a correct feature and shipping a feature that looks right until the edge case arrives. You will be reading Rust weekly and writing it occasionally.

What we mean by mid-level: you can take a feature with no hand-holding, scope it, build it, test it, and get it to production without someone checking on you daily. You do not need to have worked on an exchange before. You do need to have
