Backend Engineer
Doppler is a token launch protocol coming to Solana (and live on Base, Monad, and Ethereum Mainnet) that lets teams configure tokenomics, launch with real onchain price discovery via dutch-auction dynamic bonding curves, and graduate to deep liquidity on DEXs like Uniswap. It serves token issuers and builders—from memecoin creators to protocols and RWA issuers—through an all-in-one app and a TypeScript SDK for building custom capital markets products.

About Doppler
Doppler is a liquidity bootstrapping ecosystem and capital markets protocol that helps teams create tokenized markets, let prices form through onchain price discovery, and graduate liquidity into deep, established pools. It introduces a 'dutch-auction dynamic bonding curve' primitive to source initial two-sided liquidity while protecting users from sniping bots and MEV through auction mechanics. The protocol supports memecoins, RWAs, and protocol tokens, offering capital-efficient bonding curves, seamless migration to Uniswap v2/v4, integration with OpenZeppelin Governor treasuries for governance, and composable, programmable smart contracts for vesting, airdrops, and incentives. Doppler offers two main products: an app (app.doppler.lol) for launching and trading tokens through a purpose-built interface without needing smart contract engineering, and a TypeScript SDK (docs.doppler.lol) for developers to build custom products on top of Doppler's infrastructure, such as attention marketplaces, launchpads, and new financial primitives. It also introduced 'Multicurve,' a mechanism allowing integrators to specify custom liquidity curves instead of a single constant liquidity position. The protocol targets token issuers, developers, and integrators building onchain capital markets products.
