Senior Backend Engineer

About Us

Flashbots started in 2020 as a research and development organization formed to mitigate the negative externalities and existential risks posed by MEV. Since then, we have impacted the world of crypto through mev-geth, Flashbots Protect, MEV-Boost, MEV-Share, our open research and soon-to-be SUAVE.

Our mission is clear: illuminate, democratize and distribute. We seek to ensure that the value created on decentralized, public blockchains is transparent and distributed. We do this by conducting cutting-edge research, building mission-critical products, and coordinating a diverse community with competing interests.

Our vibe is astro-pirate-punk: irreverent, anarchic, excellent, autonomous. We’re explorers, hackers, builders, thinkers. We are relaxed, composed, and at ease in the world, but beneath our suave exterior, we do not have the time or inclination to be anything but the best.
